Investigation of grape sap on wingless/integrated and β-catenin genes expression with histological factors on the hair follicle in rat.

Background And Purpose: Natural products are used to improve the damage caused by harmful reagents in various pathological situations. This study investigated the effect of grape sap as a natural product with antioxidant properties on follicle cell proliferation in bleomycin (as a chemotherapy agent with toxic effects on hair growth) treated rats skin.

Experimental Approach: The bleomycin treated rats were administrated grape sap. Wingless/integrated (wnt) and β-catenin gene expression as follicle proliferative markers were evaluated using real-time polymerase chain reaction. Furthermore, histological factors and total antioxidant capacity were evaluated.

Findings / Results: The data showed that, grape sap increased the number of anagenic hair follicle in grape sap (100 mg/kg) group ( < 0.001), sebaceous glands ( < 0.001), blood vessel density ( < 0.001), and hair growth length ( < 0.001). Also, wnt and β-catenin gene expression was elevated. The data showed that wnt and β-catenin gene expression were elevated in grape sap treated animals versus bleomycin group ( < 0.01 and 0.001, respectively).

Conclusion And Implications: Our finding showed that grape sap can be effective in increasing hair growth a gains bleomycin toxic effects on skin hair growth.
