- the antioxidant activity of holy basil extract was investigated by evaluating the quantity of ROS produced by keratinocytes or fibroblasts subjected to oxidative stress induced by menadione. has. Material and method
- ROS were labeled with the CellRox® probe; intracellular fluorescence, proportional to the amount of ROS was measured.
- ROS are the main activators of lipid peroxidation, having as their main targets polyunsaturated lipids bound to the cell membrane.
- the anti-lipid peroxidation activity of holy basil extract was investigated in keratinocytes or fibroblasts subjected to oxidative stress induced by cumene hydroperoxide. has. Material and method
- the lipid peroxides were revealed by labeling using the BODIPY® 581/591 C11 probe; intracellular fluorescence was measured.
- Glutathione is the main endogenous antioxidant peptide capable of neutralizing ROS. Intracellular GSH depletion is responsible for damage induced by oxidative stress, associated with mitochondrial toxicity.
- Skin aging is characterized by an alteration of the dermal matrix with, in particular, a reduction in the quality and quantity of matrix fibers, mainly collagen and elastin.
- the anti-aging activity of holy basil was evaluated by its ability to stimulate the expression and production of dermal matrix markers under standard conditions and under conditions of inflammatory stress modeling chronic inflammation, also called " inflamm'aging” or low-grade inflammation.
- Collagen I The gene expression of Collagen I, Elastin, Dermatopontin and MMP1 (Matrix-Metalloproteinase-1) was evaluated by real-time quantitative PCR.
- Human dermal fibroblasts were treated for 48 hours with the holy basil extract obtained according to Example 1 at 0.001% and 0.005% ms or with a mixture of Vitamin C at 10 ⁇ M and TGFB at 5 ng/mL, used as a positive reference. .
- CLN3 encodes a lysosomal/endosomal transmembrane protein (neural ceroid-lipofuscinosis 3) involved in the regulation of the autophagy process.
- Autophagy is an intracellular detoxification process allowing the degradation and recycling of damaged proteins and organelles. This process is essential for the maintenance of cell function and homeostasis. Stimulation of autophagy is of interest in slowing down aging and extending the lifespan of cells.
- PXN encodes a focal adhesion molecule (paxillin), whose expression decreases with age and therefore represents a target for anti-aging action. Due to its crucial role in cell-matrix connections and mechanotransduction between the fibroblast and its matrix, the loss of paxillin with age could compromise cell function, resulting in the appearance or aggravation of skin aging. Inducing its expression could help restore age-related loss of collagen and dermal contractility.
- paxillin focal adhesion molecule
- Table 12 Genes modulated significantly by the 3% formulation of holy basil extract compared to the placebo (fixed at 1.00)
- Reconstructed epidermis were treated topically with a formulation (cream) containing 3% holy basil extract obtained according to example 1 or its placebo, or systemically with dexamethasone at 1 ⁇ M, an anti-inflammatory reference.

- the culture subnatants were collected, an ILIa assay was carried out on the one hand and, on the other hand, these subnatants (conditioned media) were deposited on cultures of normal human dermal fibroblasts.
- Table 14 Genes modulated by the 3% formula of holy basil in the Inflamm'aging model: gene expression in the fibroblasts incubated in the presence of conditioned media (Level of expression in relative quantity; % change compared to PMA)
- the skin is daily exposed to different types of exogenous and/or endogenous stresses, likely to alter its functioning and quality, and which can ultimately lead to irreversible damage.
- Nitric oxide is a reactive species involved in the regulation of skin homeostasis. This very unstable molecule is synthesized and released by many cell types to regulate physiological and homeostatic reactions, such as melanogenesis, healing, regulation of inflammation, immunomodulation, vasodilation...
- Glucocorticoids such as cortisol.
- HPA hypothalamic-pituitary-adrenal
- Numerous studies have described the negative effects of psychological stress on cutaneous homeostasis, leading to an alteration of immune and inflammatory responses.
- the inflammatory response includes the activation of free radicals, among which, NO.
- Camptothecin is a genotoxic compound, inhibitor of toposiomerase I, used for the induction of double strand breaks in DNA.
- Double-strand breaks were detected by immunostaining of yH2AX (phosphorylation of histone H2AX which occurs early in response to double-strand breaks) and quantified by image analysis.
- Table 15 Expression of yH2AX in keratinocytes in the presence of camptothecin stress
- UV, Pollution Environmental factors
- Intracellular ROS are mainly formed by dysfunction of the mitochondrial electron transfer chain.
- Mitochondrial DNA is particularly sensitive to ROS, resulting in the following phenomena which ultimately contribute to the aging process: decrease in energy production, increase in oxidative stress, increase in mitochondrial functions.
- Normal human dermal fibroblasts were incubated for 120 minutes in the presence of the mixture of urban pollutants at 0.1% and the holy basil extract obtained in example 1 at 0.001% and 0.005% ms.
- the analysis of autophagy and mitophagy was evaluated via a lysosomal marker and a specific dye of damaged mitochondria: Damaged mitochondria were visualized by a red fluorescence produced by reaction of a fluorochrome bound by covalent bond to the membrane mitochondrial which emits when damage to the mitochondrial membrane takes place. A lysosomal dye was used to label lysosomes and assess the colocalization of damaged mitochondria to lysosomes.
- Mitophagy is represented by the percentage of lysosomes co-localized with a signal of damaged mitochondria. Pollution increased the frequency of lysosomes containing damaged mitochondria, demonstrating an increase in the process of mitophagy. Pollution increases mitochondrial and endoplasmic reticulum stress, both of which induce damage to the mitochondrial membrane. The increase in mitophagy observed under the effect of stress is linked to cells trying to eliminate damaged mitochondria and/or malformed proteins or lipids. Holy basil extract reduced and normalized pollutant stress-induced mitophagy (fig.5).
- Aquaporin 3 plays an important role in preserving skin hydration: this transmembrane protein is involved in transporting water and glycerol into keratinocytes to maintain epidermal hydration a.
