Kim MK et al. (39) investigated the differences in gene expression of dermal papilla cells (DPs), which regulate hair growth in balding and non-balding areas, in patients with androgenetic alopecia and discovered that leucine-rich repeat containing 15 (LRRC15) was overexpressed in balding-area DP cells compared to non-balding-area DPs, inhibiting cell growth. Here, LRRC15 is linked to androgenetic alopecia.
