The research concluded that selection significantly shaped the genetic variation of the X chromosome, with certain regions affected by past selective events.

Sebaceous glands in our skin, developing during pregnancy and active in puberty, produce sebum for skin lubrication, temperature control, and fighting germs, also help in hormone regulation, and their dysfunction can cause conditions like acne and hair loss.

A specific microRNA, chi-miR-30b-5p, slows down the growth of hair-related cells by affecting the CaMKIIδ gene in cashmere goats.

Key genes linked to hair growth and cancer were identified in hairless mice.

Redheaded people may have evolved to efficiently make vitamin D in areas with less sunlight.

Researchers found 617 genes that behave differently in cashmere goat hair follicles, which could help understand hair growth.

Finding functions for unknown GPCRs is hard but key for making new drugs.

Redheaded people have higher levels of a vitamin D precursor, suggesting red hair may be an adaptation for better vitamin D synthesis in areas with less sunlight.

The mtDNA N haplogroup is linked to a higher risk of late-onset lupus and specific symptoms in Han Chinese women.

Cancer cells often have more copies of TERT and TERC genes, which helps them grow and could affect patient outcomes.

A gene mutation in mice causes permanent hair loss and skin issues.

Specific genes influence hair and cashmere growth in Laiwu black goats.

The document concludes that mouse models are helpful but have limitations for skin wound healing research, and suggests using larger animals and genetically modified mice for better human application.

Pigs without the Hairless gene showed skin and thymus changes, useful for studying human hair disorders.
