Abstract

The invention belongs to biomedicine technical fields, and in particular to a kind of enteric microorganism gene marker and its application for distinguishing liver cancer and non-liver cancer.The present invention provides a kind of for distinguishing the enteric microorganism gene marker of liver cancer and non-liver cancer, and 30 kinds of microbial genes shown in SEQ ID NO:1-30 form, and the microbial gene is enriched in human body intestinal canal.Microbial gene difference model of the invention realizes good discrimination in liver cancer and non-liver cancer patient, also demonstrates feasibility, applicability and universality of the difference model in Chinese different geographical.

Description

A kind of enteric microorganism gene marker for distinguishing liver cancer and non-liver cancer and its Using
Technical field
The invention belongs to biomedicine technical fields, and in particular to a kind of enteric microorganism base for distinguishing liver cancer and non-liver cancer Because of marker and its application.
Background technique
Liver cancer (hepatocellular carcinoma, HCC) disease incidence in global malignant tumour occupies the 6th, death Rate occupies second.China is liver cancer big country, and the highest country of global onset of liver cancer rate, and lung is only second in kinds of tumor Cancer occupies second.Due to hepatitis B and hepatitis C virus persistent infection and its caused by cirrhosis prevalence, China's liver cancer Incidence is serious.Onset of liver cancer number accounts for the 55% of the whole world at present, and death toll accounts for about whole world PLC mortality number 45%, it constitutes a serious threat to the health of our people.Since liver cancer onset is hidden, early diagnosis is difficult, and Most patients are true Later period of hepatocarcinoma, poor prognosis have been reached when examining.It is even also easy to recur after operation excision, lack effective therapeutic agent and means. Therefore, the diagnostic model for establishing difference liver cancer and non-liver cancer, realizes the early diagnosis of liver cancer, early detection, morning for liver cancer Phase diagnosis and early treatment are of great significance.
Human body intestinal canal microecosystem and health and disease are closely related.Huge number (10 is colonized in human body intestinal canal14)、 Microbiologic population's (about 1.5 kilograms) that structure is complicated (more than 1000 kinds bacteriums).Its cell total amount is almost human body own cells 10 times of quantity, gene total amount are 150 times of mankind itself's gene.During intestinal flora and host's symbiosis and coevolution, The digestion and absorption, immune response, metabolism etc. for adjusting host play a significant role.Intestinal microecology imbalance promotes chronic disease Occurrence and development, including cirrhosis, hepatocellular carcinoma, cancer of pancreas and colorectal cancer etc..
Crux function bacterium can become the new biomarkers of human diseases in enteric microorganism.The feature of intestinal microecology Or it is just more and more extensive as the differentiation tool of specified disease or tumour based on the difference model that enteric microorganism is established Report and approval." visible peristalsis visible intestinal peristalsis (Enterotypes) " of intestinal flora can reflect that people to the neurological susceptibility of disease, prompts intestinal flora tool There are potential early warning and diagnostic effect.Qin J etc. takes the lead in reporting intestinal microecology and diabetes B using metagenomics Correlation, it is indicated that 23 strains are likely to become the enteric microorganism marker for distinguishing diabetes B.Qin N, Li A etc. (2014 Year Nature magazine) Chinese population liver cirrhosis patient micro-ecological in intestines parsed by macro genomic sequencing technique, micro- On biological gene and functional level, 15 markers of cirrhosis specificity are identified, the liver for creating a high accuracy is hard Change patient's discrimination index.Ren Z etc. points out that intestinal microecology reacts more sensitive, intestinal microecology to acute rejection of liver transplantation Change Early acute rejection after can be used to predict liver transfer operation, improves the auxiliary that acute cellular rejection damages after liver transfer operation can also be become Property target.Wang Z etc. (Nature, 2011) points out that the lecithin lipid metaboli dependent on intestinal microecology promotes cardiovascular disease Progress, this is found to be the novel diagnostic method of cardiovascular disease and therapeutic strategy provides theoretical basis.Oh PL etc. The variation of (AJT, 2012) discovery intestinal microecology is closely related with small intestine transplantation repulsion, can become a potential graft rejection Diagnostic marker.Yu J etc. is disclosed in different nationalities patient and is demonstrated the microbial markers of colorectal cancer, it is indicated that micro- A kind of early diagnosis marker of the biomarker as payable, noninvasive colorectal cancer.Thus, enteric microorganism may It is the powerful of various disease diagnosis.However, for distinguishing liver cancer and the enteric microorganism model of non-liver cancer is not reported also It crosses.
Summary of the invention
The present invention provides a kind of for distinguishing the enteric microorganism gene marker of liver cancer and non-liver cancer, by SEQ ID 30 kinds of microbial gene compositions, the microbial gene shown in NO:1-30 are enriched in human body intestinal canal.
In addition the present invention also provides one kind to be used for detection reagent, including for detecting 30 shown in SEQ ID NO:1-30 The primer of kind microbial gene, sequence are as follows:
