The effect of STEAP4 (six-transmembrane epithelial antigen of the prostate 4) on goat adipocyte differentiation is unclear. We cloned the goat STEAP4 gene based on the Jianzhou Da’er goat and analyzed its properties and its expression in tissues and adipocytes; further, the positive effect on the expression of subcutaneous adipocytes was obvious. This study will provide a basis for elucidating the biological function of the STEAP4 gene in goat and provide a reference for goat molecular breeding.

Tissue inhibitor of metalloproteinase 1 (TIMP1) plays a crucial role in follicle growth and embryonic development. Ovarian granulosa cells also play an essential role in these processes. However, the effect of TIMP1 on the biological function of goat ovarian granulosa cells remains unknown. The objective of this study was to explore the impact of TIMP1 on granulosa cell proliferation and reproductive characteristics in goats.

Cashmere is a natural fiber from cashmere goats. The textile has been favored by consumers due to typical features like lightness, softness, and comfort. In this study, we show that circRNA-0100 promotes the differentiation of secondary hair follicle stem cells into hair lineage via sequestering miR-153-3p to heighten the KLF5 expression. Our results provide significant information for artificially regulating the secondary hair follicle regeneration and cashmere growth in cashmere goats.

Intramuscular fat is a type of fatty tissue deposited between skeletal muscle fibers and muscle bundles, which is regulated by the number and size of preadipocytes in the muscle, and it is a key factor affecting meat tenderness and juiciness. As a member of miRNAs, a variety of studies suggested that miR-25-3p may play an important role in regulating lipid metabolism and adipocyte differentiation. This study attempts to investigate the role of miR-25-3p in goat intramuscular preadipocytes.

This study provided a theoretical and experimental basis for further studying the molecular regulation mechanism of hair follicle development. EDA and EDAR were both expressed in the skin tissue in the seven cashmere goat embryo stages. Moreover, EDA and EDAR play an important role in the formation of embryonic placode (Pc). After interfering with EDA and EDAR, the expression of BMP2, BMP4, noggin, β-catenin, TGF-β2, Wnt-10b, and NOTCH1 in fibroblasts and epithelial cells changed significantly.
