This study found that activation of delta-opioid receptors in keratinocytes may delay the expression of the PER2 gene, suggesting a possible link to cancer development through circadian rhythm disruption.
February 2024 in “Journal of medicinal food” This study reports that the β-catenin inhibitor tegatrabetan reduced hair growth and hair follicle numbers in mice, suggesting its potential as a model for developing new hair growth materials.
March 2026 in “Frontiers in Veterinary Science” This study found that all-trans retinoic acid (ATRA) inhibits proliferation and promotes apoptosis in secondary hair follicle-derived dermal papilla cells from cashmere goats, likely via the TGF-β2/Smad2/3 signaling pathway.

April 2017 in “European Journal of Cell Biology” This study observed that CIP/KIP proteins play a significant role in regulating cell cycle arrest and differentiation in human hair follicles, supporting hair growth and formation in the anagen phase.
