Studysummary This study reported variable expression levels of TRα and CRABPII genes during the prenatal development of cashmere goats, contributing to an understanding of hair follicle formation in these animals. Our plain-language summary of this paper — not a Tressless recommendation.

The study investigated the expression patterns of TRα and CRABPII genes in the fetal skin of Chinese cashmere goats during prenatal development using real-time quantitative PCR (RT-qPCR). TRα was expressed at high levels at embryonic day (E) 70, decreased slightly from E75 to E90, and peaked at E130. CRABPII mRNA showed an 'up-down-up' trend, with the highest expression at E75, a significant down-regulation from E80 to E120, and a mild increase at E130. These findings provided insights into the dynamic expression of these genes during cashmere formation, potentially informing further studies on their roles in regulating cashmere growth in goats.
