January 2023 in “Frontiers in Genetics” In this study, researchers generated transgenic mice with skin-specific overexpression of ovine β-catenin to investigate its role in hair follicle development. The ovine β-catenin gene was successfully integrated and inherited across six generations, as confirmed by PCR and Southern blot tests. qRT-PCR and western blot analyses showed specific expression of β-catenin mRNA in the skin. Phenotypic analysis of the sixth generation revealed that overexpression of β-catenin increased hair follicle density by accelerating the catagen-to-anagen transition, indicating that ovine β-catenin can promote hair follicle development in mice, demonstrating domestication traits in animals.

October 2022 in “International Journal of Molecular Sciences” The study investigated the effects of fish collagen peptides (CP) on hair growth in human dermal papilla cells and C57BL/6 mice, focusing on the Wnt/β-catenin and BMP signaling pathways. CP significantly enhanced cell proliferation and hair regrowth, with the CP1000 group showing results comparable to finasteride. CP increased the expression of hair growth factors (IGF-1, VEGF, krt27, Gprc5d, Ki67) and decreased TGF-β1, a growth inhibitor. Protein analysis revealed that CP upregulated Wnt10b and β-catenin levels while downregulating BMP4 and BMP6 levels. The findings suggest that CP could be a promising nutraceutical for hair loss prevention and regrowth.
