May 2018 in “Asian-Australasian journal of animal sciences” OCIAD2 and DCN genes affect hair growth in goats by having opposite effects on a growth signaling pathway and inhibiting each other.
1 citations,
May 2017 in “InTech eBooks” Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.
13 citations,
April 2015 in “Actas Dermo-Sifiliográficas” The document concludes that recognizing specific histological features of different nonscarring alopecias is crucial for accurate diagnosis and understanding hair loss progression.
122 citations,
