Scientists found 53 keratin genes in yaks that are important for hair growth and share similarities with those in other animals.

Human hair keratin genes are similar to mouse genes and are specifically expressed in hair follicles.

Keratin 18 helps diagnose and predict cancer progression and affects cancer growth and spread.

Environmental factors can cause mutations in skin proteins, leading to skin disorders.

Skin cells and certain hair follicle areas produce hemoglobin, which may help protect against oxidative stress like UV damage.

Understanding hair biology is key to developing better treatments for hair and scalp issues.

Explosions don't stop hair proteins from being used to identify people.

Odontogenic keratocysts are caused by abnormal Hedgehog signaling and can lead to tooth and bone issues.

The research identified two types of keratinocytes in chicken scales: one for hard scales and another for soft skin, with similarities to human skin differentiation.

The KRTAP21-1 gene affects wool yield and can help improve wool production.

The KRTAP21-2 gene affects wool length and quality in sheep.

The KRTAP36-2 gene in sheep affects wool yield.
