This study identified overexpression of certain immune-related genes and underexpression of genes in specific signaling pathways in premature androgenetic alopecia, suggesting potential new therapeutic targets.

This article describes a potential novel approach to reduce chemotherapy-induced hair loss by enhancing the expression of specific transporters in hair follicles, but reports no clinical results.

This study found that MED1 deficiency in keratinocytes accelerates skin wound healing in young mice but delays healing in older mice, suggesting differential roles in epidermal regeneration with age.

This study found that maternal sub-maintenance nutrition reduced the density and branching ratio of secondary wool follicles in Merino sheep fetuses and identified genes potentially involved in these processes.

This study suggests that miRNAs, particularly miR-195-5p, may regulate the loss of hair follicle inductivity in cultured dermal papilla cells by suppressing the Wnt/β-catenin pathway.

This review discusses the multifaceted roles of hair follicles in skin health, including potential contributions to skin neoplasias, and reports no new results.
