Researchers found that certain RNA sequences play a role in yak hair growth and these sequences are somewhat similar to those in cashmere goats.

Keratin 33A is a key protein in goat winter coats, especially in high-producing breeds.

Animal hair fibers like wool and mohair are strong when dry, but vicuna fibers are very brittle.

Otter rabbit, mink, and blue fox fur can be identified by their unique hair structures.

Removing the VDR gene in skin cells reduces their growth and affects hair-related genes.

circRNA-1926 helps goat stem cells turn into hair follicles by affecting miR-148a/b-3p and CDK19.

DNA methylation changes are linked to hair growth cycles in goats.

Goat hair follicles have insulin-like growth factor-I receptors that might affect hair growth, but no melatonin receptors were found.

The analysis found genes linked to skin and hair development are more active in Pashmina goats, which may explain their long-fiber production.

Melatonin helps hair grow by activating the RORα receptor in goats.
