Definitions
- the field of the invention is that of uronephrology. More specifically, the invention relates to a method for in vitro diagnosis of pathologies of the urinary system.
- Renal diseases can reach the different structural compartments of the kidney: vessels, glomeruli, tubules, interstitium. These disorders lead to acute and / or chronic renal failure, their ultimate evolution being the complete destruction of the functional units of the kidney, replaced by an expansion of the extracellular matrix, that is to say renal fibrosis.
- the renal diseases can touch the native kidneys or the allografts after a kidney transplant. In France, an estimated 3000 new cases of transplant patients per year (kidney, heart, liver, marrow, lung ).
- the systematic follow-up of the transplant patients made it possible to study the early stages of renal diseases evolving towards fibrosis.
- the expression in renal tissue of epithelial-mesenchymal (MP) transition markers allows early detection of fibrosing renal tissue disease, which can be caused by ischemia, rejection and / or toxicity of immunosuppressive agents, cyclosporine A (CsA) in particular (Slattery et al., Am J Pathol 2005 Aug; 167 (2): 395-407; Hertig et al., American Journal of Transplantation 2006, Galichon et al., Fibrogenesis Tissue Repair 2011, Galichon et al, Transplantation, 2011).
- CsA cyclosporine A
- TEM is a dynamic process in which cells lose their epithelial characteristics and acquire mesenchymal characteristics. These changes affect both the morphology of the cell and its operation. When it reaches the renal tubular cells, it shows a progression to fibrosis and chronic renal failure (Hertig et al., J Am Soc Nephrol 2008). It is therefore necessary to monitor the occurrence of this phenomenon in transplant patients in order to adapt or modify the immunosuppressive treatment.
- the reference method used for the detection and monitoring of any renal pathology is biopsy.
- the biopsy involves taking a carrot of tissue in the kidney transcutaneously, transvenously, or surgically. This sample is then subjected to histological examination for signs of possible pathology (destruction, cellular infiltration or hypertrophy of the glomerular, tubular, vascular or interstitial compartments).
- the sampling is not without risk for the patient. Many complications are observed such as hematuria, renal insufficiency on an obstacle or even anuria, the appearance of hematomas in the perirenal region, the appearance of arteriovenous fistulas, and, more rarely, the haemorrhage, the loss graft, death. In addition to the risks associated with any invasive procedure, it is possible to perform the biopsy in a region that is not representative of the overall state of the kidney and therefore to underestimate or overestimate the patient's actual situation as a result of this sampling.
- the invention particularly aims to overcome these disadvantages of the prior art.
- an object of the invention is to provide, in at least one embodiment, a method for early diagnosis of renal pathologies or pathologies having renal effects.
- Another object of the invention is to implement, in at least one embodiment, a non-invasive diagnostic method.
- the invention also aims to implement, in at least one embodiment, a reliable and accurate diagnostic method.
- Another object of the invention is to implement, in at least one embodiment, a simple diagnostic method to achieve.
- Another object of the invention is to implement, in at least one embodiment, a more economical diagnostic method.
- Another object of the invention is to implement, in at least one embodiment, a method of monitoring the efficiency and tolerance of a treatment.
- Another object of the invention is to implement, in at least one embodiment, a less painful diagnostic method for the patient.
- such a method comprises the following steps:
- the invention is based on the use of the cells and microparticles contained in the urine in order to extract the genetic material and to compare the expression of a gene of interest, correlated with a pathology, with the expression of a gene specific for urinary cells not affected by the pathology.
- Urine contains a small amount of urothelial cells, derived from the normal renewal of the epithelium of urinary excretory pathways. It may also contain, in a variable amount, depending in particular on the presence of a renal pathology, leucocytes, tubular or renal glomerular cells, blood ... as well as microparticles.
- microparticles are meant the complex vesicular structures that can be released by most cells during activation or apoptosis processes. They are composed of a double layer of phospholipids exposing transmembrane proteins and receptors and contain cytosolic components such as enzymes, transcription factors and A Nm from their parent cells.
- urothelial cells refers to the transitional epithelial cells that make up human purothelium, from the pelvis to the urethra. These cells have various forms: cylindrical, kite, umbrella, balloon.
- specific marker of urothelial cells means a gene specifically expressed by urothelial cells or urothelial microparticles, whether inside the cells or on their surface, and the level of synthesis by said cell is independent of the pathologies that may be affect the kidney cells. This notion is therefore different from the notion of housekeeping gene in which the expression is ubiquitous, whatever the cell type, the function of the cell or its state.
- One of the contributions of the invention is therefore the normalization of the expression of the gene of interest by the expression of a gene independent of the affected cell types.
- This normalization step makes it possible to determine an expression threshold of the pathological marker with respect to a urinary marker independent of the quantitative and qualitative variations of urinary cells of renal origin. It is then possible to know if this marker is expressed in a significant way or, on the contrary, very weak.
- This feature provides a reliable, accurate diagnostic test that more accurately reflects the patient's state of health.
- the method according to the invention can be used for diagnostic purposes or to monitor the evolution of a pathology.
- working from a urine sample has many advantages: the sample is easily accessible;
- the sample is non-invasive and painless
- this standardization process can be applied to various pathologies, renal or non-renal, since these pathologies modify the expression and / or the quantity of urothelial cells and / or microparticles excreted and present in the urine.
- the invention further relates to an in vitro diagnostic method wherein step b) comprises detecting the transcript of said at least one urothelial cell specific marker and / or urothelial microparticles and said at least one transcription product. marker of said pathology.
- the study of transcription products is more reliable than the study of the presence of a gene in the genome of the cell. It is indeed known that the presence of a gene in the genome of a cell is not necessarily correlated with its expression in said cell, the regulation of the expression of a particular gene being subjected to many parameters. The detection of the transcription product thus makes it possible to obtain a more precise and reliable result.
- step b) is implemented by means of a nucleic acid amplification technique chosen from the group comprising RT-PCR, quantitative PCR and PCR. in end point, semi-quantitative PCR or their combination.
- PCR Polymerase Chain Reaction
- RT-PCR Reverse-Transcriptase Polymerase Chain Reaction
- Quantitative PCR also known as real-time PCR, is understood to mean the in vitro replication technique of a targeted DNA fragment that furthermore makes it possible to measure the initial quantity of this target fragment.
- Semi-quantitative PCR differs from quantitative PCR in that PCR is interrupted in several points, to evaluate the amount of initial DNA. This type of PCR is useful when the amount of DNA is unusually low. End-point PCR combines the Northern blot technique with conventional PCR to evaluate the initial amount of DNA through comparison of agarose gel bands.
- the invention further relates to an in vitro diagnostic method wherein step b) is carried out using a nucleic acid hybridization technique selected from the group consisting of in situ hybridization (ISH), fluorescence-labeled in situ hybridization (FISH), biochip, Northern blot or Southern Blot.
- a nucleic acid hybridization technique selected from the group consisting of in situ hybridization (ISH), fluorescence-labeled in situ hybridization (FISH), biochip, Northern blot or Southern Blot.
- the invention also relates to an in vitro diagnostic method in which step b) is implemented via a nucleic acid sequencing method.
- the invention further relates to an in vitro diagnostic method wherein said pathology is renal pathology and is selected from the group consisting of renal fibrosis, phenotypic change of renal epithelial cells, graft rejection, cancer, glomerular diseases (diabetes, extramembranous glomerulonephritis, minimal glomerular lesions, segmental and focal hyalinosis ...), tubular diseases (acute tubular necrosis, expression of epithelial-mesenchymal transition markers, atrophy, cell rejection, excretory tract obstruction, etc.) , interstitial diseases (inflammation, fibrosis), vascular diseases of the kidney (arterial hypertension, thrombotic microangiopathy, humoral rejection, etc.).
- renal pathology is renal pathology and is selected from the group consisting of renal fibrosis, phenotypic change of renal epithelial cells, graft rejection, cancer, glomerular diseases (diabetes, extramembranous glomerulonep
- TEM epithelio-mesenchymal transition
- Epithelial phenotypic changes are markers of TEM (eg, vimentin and ⁇ -catenin in tubular epithelium) that can be studied in tissues in clinical situations (Hertig A et al., Early Epithelial phenotypic changes predict graft Brooks, J Am Soc Nephrol, 19 (2008) 1584-1591).
- Another object of the invention is a method in which said patient has received an organ transplant and said renal pathology is the presence of interstitial fibrosis, tubular atrophy or epithelial-mesenchymal transition markers in the renal graft.
- the method according to the invention thus makes it possible to detect effectively and early the occurrence of a renal pathology such as inflammation or TEM, inducing epithelial phenotypic changes in the kidney.
- the invention also relates to an in vitro diagnostic method in which at least one genetic marker specific for said renal pathology is selected from the group comprising the human genes of CD45 (SEQ ID 1), CD68 (SEQ ID 2), and VIM (SEQ ID NO: 3) as well as genes having a sequence homology of at least 80%, preferably at least 85%, preferably at least 90%, preferably at least 95%, of preferably at least 99% with these.
- the human gene CD45 also has the symbol PTPRC (Protein Tyrosine Phosphatase Receptor type C).
- PTPRC Protein Tyrosine Phosphatase Receptor type C
- the inventors have surprisingly discovered that the expression of these genes is considerably increased in the urine of clinically stable kidney transplant patients, but whose biopsy of the graft demonstrates the presence of phenotypic epithelial changes.
- This over-expression is correlated with the presence of epithelial phenotypic changes, occurring during an epithelial-mesenchymal transition, and tubulointerstitial involvement on renal allograft biopsies, these biopsies being performed as part of a systematic screening three months after transplantation. It is possible, within the meaning of the invention, to search for the expression of only one gene, a marker specific for a pathology.
- markers for clear cell carcinoma include the search for racemase, caveolin-1 (SEQ ID 29), ROR1 (SEQ ID 30), CD10 (SEQ ID 31), keratin 7 , vimentin (SEQ ID 3), TP53 (SEQ ID 26) in the context of monitoring renal cancer.
- a "homologous sequence” or a "sequence homology" between two nucleotide sequences is determined by the linear comparison of the nucleotide sequences by the Basic Local Alignment Search Tool (BLAST), a blastn algorithm available on the NCBI site:
- BLAST Basic Local Alignment Search Tool
- database human genome + transcripts (human genomic plus transcript) (Human G + T);
- blastn Somewhat similar sequences
- said pathology is a pathology modifying the quantity of cells and / or microparticles excreted in the urine.
- said pathology modifying the quantity of cells and / or microparticles excreted in the urine is chosen from the group comprising glomerular diseases such as segmental and focal hyalinosis, tubular diseases such as acute tubular necrosis and epithelial phenotypic changes. , cell rejection and interstitial diseases such as acute rejection of a graft, Sjögren's disease and sarcoidosis.
- glomerular diseases such as segmental and focal hyalinosis
- tubular diseases such as acute tubular necrosis and epithelial phenotypic changes.
- cell rejection and interstitial diseases such as acute rejection of a graft, Sjögren's disease and sarcoidosis.
- the method according to the invention makes it possible to reliably, rapidly and noninvasively detect the development of non-renal diseases by collecting a urine sample from the patient, since these pathologies modify the gene expression profile. and / or the amount of cells excreted in the urine.
- Tubular necrosis results in an increase in the number of tubular cells in the urine, due to a large desquamation of the walls of the renal tubular epithelium.
- Segmental or focal hyalinosis is accompanied by a large amount of podocytes in the urine.
- the increase in the number of leucocytes is a sign of an acute rejection of a graft.
- said at least one marker specific for urothelial cells is selected from the group comprising the human genes of uroplakin 1A (SEQ ID 4), uroplakin 1 B (SEQ ID 5), uroplakin 2 (SEQ ID 6 ), uroplakin 3A (SEQ ID 7), uroplakin 3B (SEQ ID 8), uroplakin 3BL (SEQ ID 9), BcasI (SEQ ID 10), CEP152 (SEQ ID 11), CRABP2 (SEQ ID 12), DNASE1 (SEQ ID 13), KRT20 (SEQ ID 14), PLEKHF1 (SEQ ID 15), PLEKHG4B (SEQ ID 16), RCN1 (SEQ ID 17), SEMA5B (SEQ ID 18), SULT2A1 (SEQ ID 19), ), TFF1 (SEQ ID NO: 20), VILL (SEQ ID NO: 21), ZNF720 (SEQ ID NO: 22) as well as genes having a sequence homology of at least 80%,
- urothelial cells express these genes. These genes are specifically and consistently expressed by urothelial cells and / or microparticles, independently of renal pathologies. Of course, these genes are present in the genetic material contained in the nucleus of each cell of the body. However, not all genes are expressed in the same way by all cells in the body. In other words, not all genes are transcribed from DNA to mRNA and then translated from mRNA to protein in all cells in the human body. However, the inventors have discovered that among the cells and the microparticles contained in the urine, these genes are specifically expressed by the urothelial cells and this, steadily.
- genes linked to a pathology specifically affecting the renal cells or modifying their quantity in the urine are thus constitute reference frames of choice for the normalization of genes linked to a pathology specifically affecting the renal cells or modifying their quantity in the urine.
- the inventors wish to emphasize that the aforementioned genes can, in fact, be detected in other cell types, for example when this detection is based on the simple search for the presence of a gene in the total DNA and not on the genes expressed by a cell type. These genes can also be expressed by other cell types.
- their interest in the present invention is related to the fact that, of all the cell types that can be found in a urine sample of a patient, only urothelial cells express these genes, regardless of pathological conditions.
- the concept of specific marker of urothelial cells, or urothelial microparticles is to be distinguished from the concept of household gene.
- household genes are genes expressed by all cells, regardless of their cell type and function.
- specific marker of urothelial cells corresponds to genes expressed solely by urothelial cells among all the cells likely to end up in a urine sample.
- said at least one specific marker for urothelial cells or urothelial microparticles is chosen from the group of genes comprising the human genes UPK1A, UPK1B, UPK2 and UPK3A as well as genes having a sequence homology of at least 80%, preferably at least 85%, preferably at least 90%, preferably at least 95%, preferably at least 99% with these.
- Normalization means the elimination of bias due to measurement or manipulation errors, and independent of biological variation. The standardization step therefore makes it possible to produce more reliable results. Normalizing by using specific genes of the cells affected by the pathology sought makes it possible to eliminate the bias linked to the proportion of these same cells in the urine sample. Indeed, the quantitative and The quality of the urine is not fixed either because of the urinary flow or because of the disease. The risk of underestimating the real progression of the pathology in the patient is therefore real, and could be harmful for its therapeutic management.
- normalization is a logarithmic scale (which corresponds to the raw result) on a linear scale in two steps:
- the operator should measure the optical densities of each migration band with any standard software (Image J TM, UN-SCAN-IT Gel TM) and report back to determine the expression threshold of the gene of interest in the patient.
- the expression threshold is then calculated as follows:
- the invention also relates to an in vitro diagnostic method further comprising a step of comparing the expression threshold of said marker of a renal pathology to a threshold of expression unchanged by the disease.
- the invention further comprises an in vitro diagnostic kit for the detection of pathologies from a urine sample from a patient comprising at least one pair of primers for detecting in said sample at least one pathology-specific marker and at least one pair of primers for detecting at least one urothelial-specific marker.
- said pathology is a renal fibrosis or a phenotypic change of the renal epithelial cells
- said at least one marker specific for a renal pathology is selected from the group comprising the human genes of CD45, CD68 and VIM.
- said at least one specific marker for urothelial cells is selected from the group comprising the human genes of uroplakin 1A, uroplakin 1B, uroplakin 2, uroplakin 3A, uroplakin 3B, uroplakin 3BL, Bcas1, CEP 152, CRABP2, DNASE1, KRT20, PLEKHF1, PLEKHG4B, RCN1, SEMA5B, SULT2A1, TFF1, VILL, ZNF720 as well as genes having a sequence homology of at least 80 %, preferably at least 85%, preferably at least 90%, preferably at least 95%, preferably at least 99% with these.
- Another object of the invention is the use of the in vitro diagnostic kit for the detection of a renal pathology, said renal pathology being a fibrin or a phenotypic change of renal epithelial cells.
- Figure 1 presents a graph showing the correlation of the TEM scores with the GAPDH standardized vimentin urinary PCR (VIM) results.
- FIG. 2 illustrates the correlation of the same TEM scores with the same urine PCR results for vimentin (VIM), when the latter are normalized by the UPK1A uroplakin 1A gene.

- FIG. 4 shows the correlation of the same TEM scores with the same urinary PCR results for CD68, when the latter are normalized by the UPK1A uroplakin 1A gene.
- Figure 5 shows the correlation of the TEM scores with the results of urinary CD45 PCR, standardized by GAPDH.
- FIG. 6 describes the correlation of the same TEM scores with the same CD45 urinary PCR results, when the latter are normalized by the UPK1 A uroplakin A gene.

- Figure 8 is a graph showing the significance of gene enrichment for the term "kidney” and the term “intercellular junction” as a function of the normalization method.
- the general principle of the invention rests on the comparison of the expression of a gene correlated with a pathological phenomenon, designated as a marker of a pathology or pathological marker, on the expression of a reference gene whose level of Expression in urothelial cells is independent of the cells affected by the pathology.
- the latter is designated as a specific marker for urothelial cells.
- Example 1 Diagnosis of renal graft epithelial phenotypic changes by the method according to the invention.
- the urine sample is centrifuged at 2000 rpm for 20 min at room temperature (T amb ). A volume of 2 ml of supernatant is stored at -80 ° C. The remainder of the supernatant is removed. The pellet, containing the cells and the minerals, is taken up in a volume of 15 ml of PBS1X buffer solution. The cell suspension is again centrifuged to remove the debris for 10 min, at 2000 rpm, T amb - The supernatant is removed, the pellet is drained by inversion of the tube before being resuspended in 150 ⁇ l of lysis buffer RLT, supplemented per 1% by volume of ⁇ -mercaptoethanol (14.3 M solution).
- the RLT buffer is provided by Qiagen Laboratories, in the RNeasy® micro kit. At this stage, the lysate thus obtained can be stored at -80 ° C or can be directly used to carry out RNA extraction.
- mRNAs messenger RNAs
- Indicator markers for pathology, fibrosis or MMT do not are usually expressed only when these phenomena appear. Studying their transcription is therefore more relevant than looking for their presence in the genome.
- the ARs are extracted from the cell lysate, prepared as previously described, using the RNeasy® micro kit (Qiagen) according to the protocol provided by the manufacturer. Specifically, the protocol followed is the protocol "Fabrics obtained by microdissection". Briefly, a volume of 70% sterile ethanol is added to the homogenized lysate, as indicated in the protocol. The lysate is deposited, wholly or partly, in an RNeasy® column, supplied with the kit. The columns are centrifuged for 15 seconds, at a rotation speed greater than 10,000 rpm, at 4 ° C. The effluent is eliminated. The column is washed with RW1 buffer, supplied with the kit. The RNAs are eluted and then recovered in 14 ⁇ l of water devoid of RNAse.
- RNA reverse transcription of previously extracted RNAs is performed using the QuantiTect® Reverse Transcription Kit (Qiagen). Briefly, the previously produced RNA solution is supplemented with gDNA Wipeout Buffer, provided in the kit, before being incubated at 42 ° C for 2 min. This step makes it possible to eliminate the residual genomic DNA.
- the retro-transcriptional mixture contains the nucleic bases (RT Primer Mix), the retro-transcriptase (Quantiscript® Reverse Transcriptase) and the reaction buffer (Quantiscript® RT Buffer). It is added to the RNA solution. The mixture is incubated for 15 min at 42 ° C for retro-transcription. The mixture is then incubated for 3 min at 95 ° C to inactivate the retro-transcriptase.
- the complementary DNA solution thus prepared may be stored or diluted to l / 10th before analysis. 4. Quantitative PCR.
- Quantitative PCR is used to evaluate the initial amount of transcirption products in cells. It thus makes it possible to determine whether a gene is overregulated or underregulated.
- the primer pairs used are provided by Roche Laboratories:
- Vimentin is a protein belonging to the family of intermediate filaments. The gene symbol encoding it is VIM. She participates in the cytoskeleton.
- CD45 or PTPRC, is a transmembrane protein tyrosine phosphatase, normally expressed by leukocytes.
- CD68 is a glycoprotein, normally expressed by macrophages and monocytes.
- VIM vimentin

- the uroplakin 1A gene is used as a reference gene, specific for urothelial cells.
- the amplification program is as follows:
- the plate containing the amplified DNA is removed from the automaton and stored at 4 ° C.
- the raw results are retrieved from the PLC for normalization. 5. Standardization
- the raw results are normalized according to the reference method used to calculate the amount of initial DNA, during a quantitative PCR. Briefly, the results of each patient were standardized and then linearized as follows:
- GPDH household gene
- the Cp being the number of amplification cycles before detection of the fluorescent signal by the apparatus.
- Figures 1 and 2 show the correlation of the quantitative PCR results on the vimentin gene, correlated with the TEM scores. According to Figure 1, the coefficient of
- Figure 4 shows that normalization with uroplakin greatly improves the test.
- the slope of the regression line becomes positive and the expression of CD68 is positively regulated during phenotypic epithelial changes. This result is consistent with the anatomopatho logical examination on control biopsies.
- test improves considerably when uroplakin is used as a reference gene for standardization of results.
- vimentin CD68 and CD45 (PTPRC) is positively regulated in the phenomena of TEM in the kidney. This corresponds to what is actually observed in immunohistochemistry on patients' biopsies.
- the method according to the invention reflects the actual situation of the patient. It also makes it possible to accurately and reliably monitor and diagnose the occurrence of epithelial phenotypic changes in the kidney.
- Example 2 Detection of Urine-Expressed Genes in 26 Patients With or Without Epithelial Phenotypic Changes on Graft Biopsy and comparing the results obtained according to the conventional normalization method and the method according to the invention.
- Example 1 Twenty-six clinically stable patients had a urine sample as described in Example 1, before biopsy of the graft. Of the 26 patients analyzed, 12 had no evidence of EMT while 14 had the signs. Cell pellets were prepared from these urine samples as described in Example 1. These cell pellets were then sent to Miltenyi Biotech Gmbh for RNA extraction, reverse transcription in complementary DNA, amplification, incorporation of fluorescent label. of DNA, quality controls, and hybridization on Agilent® complementary DNA chips. These chips make it possible to study quantitatively the expression of genes representing all the human genes. The transcriptome of each patient was therefore analyzed on a chip. In other words, a chip corresponds to a patient.
- the expression level of the genes is expressed in fluorescence intensity after adjustment on internal fluorescence controls present on each chip: these are the raw data.
- the median here corresponds to the brightness emitted and recorded for the gene located at the median of the list of genes analyzed on the complementary DNA chip.
- a normalization by the median makes it possible to eliminate the biases related to the preparation of each of the chips.
- An example of bias related to the preparation of the chip is the amount of fluorescent label incorporated into the patient's DNA or the temperature at which the chip is exposed. Normalization by the median is performed by applying to each gene tested on the complementary DNA chip for a given patient the following formula:
- x represents each gene tested on the complementary DNA chip separately tested in this model the blood and SFN covariates are respectively the average value of the hemoglobin genes and the average value of the laminate from the expression measurements delivered by the complementary DNA chip of a given individual.
- the setting of the blood and the layer in the covariate makes it possible to take into account contamination of the sample by blood and / or non-renal epithelial cells.
- the inventors have observed on the one hand the enrichment of the term "kidney” in the UP TISSUE database in order to evaluate the consistency of the results obtained by the implementation of the normalization method according to the invention with respect to the studied organ, and on the other hand the enrichment of the term "intercellular junction” (GO: 000591 l ⁇ cell-cell junction) in the database GOTERM CC FAT to evaluate the coherence of the results with respect to the studied pathology, here ⁇ .
- the method according to the invention has thus demonstrated its effectiveness for the early detection of the appearance of phenotypic changes.
- Other applications than the detection of the TEM are possible thanks to the method according to the invention.
- the detection of acute rejection of a renal graft can be diagnosed by the method according to the invention.
