This study identified differences in adverse symptoms among patients with post-finasteride syndrome based on short and long androgen receptor gene polymorphisms.

This review discusses sex differences in immune response to respiratory viral infections, including SARS-CoV-2, and highlights that hormones like estrogen may provide females with better protection, but it reports no new results.

This study found no significant difference in CAG repeat numbers of the androgen receptor gene between Han Chinese women with female pattern hair loss and healthy controls, suggesting it may not be a genetic marker for FPHL in this population.

This study observed significant differences in hair and cashmere properties among three goat breeds in Southwest China, noting better quality cashmere in Inner Mongolia cashmere goats and their crossbreed compared to Dazu black goats.

This study found differences in melanin content and gene expression in skin under black and white hair of giant pandas, providing a basis for further research on hair color distribution and skin diseases.

This review discusses sex differences in Parkinson's disease and highlights that while men are more frequently affected, androgen-modulating treatments have not yet proven effective for PD, though 5α-reductase inhibitors show potential for further study.

This study used genomic analysis to reveal moderate genetic diversity, minimal inbreeding, and specific genes under positive selection in Xiangdong black goats, highlighting their unique adaptation traits and potential for breeding and conservation.

This study constructed a genomic map of copy number variations in fine-wool sheep, revealing their potential impact on traits like growth, nutrient metabolism, and susceptibility to selection pressures.

This research suggests that mouse mutants and genomics can help study hair biology and epithelial differentiation by focusing on the role of the Foxn1 gene.

This study found differences in urinary androgen and estrogen concentrations between male pattern baldness patients treated with finasteride and healthy controls, suggesting potential biomarkers for post-finasteride syndrome.

This study reported that exogenous R-spondin-1 can restore hair follicle neogenesis in adult mouse cells, highlighting differences in gene expression and signaling pathways between fetal and adult dermal papilla cells.

Alopecia areata is linked to immune system differences, with specific biomarkers like CXCL9 and CXCL10 being key for diagnosis and potential treatment targets.

This study identified five master regulators that mediate molecular differences in hair follicle development and sexual dimorphism in the skin, providing insights into male pattern baldness and hair follicle donor dominance.

This study suggests that fibroblast growth factors exhibit significant expression differences in rodent and primate skin, potentially related to their evolutionary paths and environmental adaptations.

In this study, differences in protein expression related to twin lambing were identified in Tibetan sheep, providing insights into the reproductive performance and fertility improvement strategy for sheep in the Qinghai-Tibet Plateau.

This study found that cashmere has a significantly smaller mean fiber diameter compared to sheep and goat wool, and identified key proteins that may influence this difference.

This study identified significant genetic associations with frontal fibrosing alopecia at four genomic loci, suggesting it is a genetically predisposed immuno-inflammatory disorder influenced by the HLA-B*07: 02 allele.

This pilot study found that hair metabolome analysis may help differentiate pregnancy complications from healthy pregnancies by revealing significant metabolite differences between trimesters.
