February 2026 in “The Plant Journal” This study found that in Arabidopsis, root hair-specific proteins ADF8 and ADF11 are crucial for responding to hormonal signals like auxin and ethylene, which in turn modulate actin filament dynamics and are key for root hair growth under various environmental conditions.
November 2025 in “Scholarly Commons (Embry–Riddle Aeronautical University)” This review discusses how urban air pollutants may influence the regulation of JAK3 signaling in alopecia areata and reports no new experimental results; the authors integrate existing data to map potential pathways and biomarkers.
July 2017 in “D-Scholarship@Pitt (University of Pittsburgh)” This study found that canonical Notch signaling inhibits Merkel cell specification during embryogenesis, while skin abrasions decrease Merkel cell number only in hairless mice.
September 2016 in “Journal of Dermatological Science” This study found that protein extracts from embryonic skin can induce hair follicle neogenesis in mice by activating insulin/IGF signaling in adult fibroblasts.
