    TLDR miR-129-5p affects hair growth by targeting the HOXC13 gene.
    The study found that miR-129-5p played a significant role in hair follicle growth in Angora rabbits by targeting the HOXC13 gene. Overexpression of miR-129-5p was associated with reduced expression of hair follicle development-related genes and increased expression of genes like SFRP2, TGF-β1, and FGF2, similar to the effects of HOXC13 knockdown. Conversely, miR-129-5p knockout had effects akin to HOXC13 overexpression. Additionally, miR-129-5p promoted apoptosis and inhibited proliferation of dermal papilla cells, while its inhibition reduced apoptosis and promoted proliferation. These findings suggested that miR-129-5p could be crucial for understanding hair follicle development and might offer new approaches for diagnosing and treating hair loss in humans.
