Hairless gene Tgf-β2 miR-31 alopecia hair loss Hr^Hp mice genetic interactions molecular interactions Hairless TGF-beta 2 microRNA-31 baldness

TLDR HR protein causes abnormal hair cycles by increasing Tgf-β2 and reducing miR-31.

The study investigated the molecular mechanisms behind hair loss in "Hairpoor" (Hr^Hp) mice, focusing on the role of the Hairless (Hr) gene. Researchers found that the Hairless gene up-regulated the expression of Tgf-β2 by down-regulating miR-31 in the skin of these mice. This regulatory pathway contributed to the hair loss phenotype observed in Hr^Hp mice. The findings provided insights into the genetic and molecular interactions involved in hair growth and loss, potentially informing future therapeutic strategies for conditions like alopecia.
