Hair and nails are skin parts that develop early and serve protective and functional roles.

Skin symptoms can indicate endocrine disorders and have various treatments.

Two specific hair keratin genes are active during hair growth and decline as hair transitions to rest.

Scientists made antibodies to tell cashmere and wool apart, which could improve how we identify animal fibers.

Anabolic steroids can build muscle and strength but have risks and need more research on their clinical benefits and side effects.

Human dermal fibroblasts are the main cells targeted by a virus that can cause a deadly skin cancer, and a certain inhibitor can effectively block this infection.

Ephrins slow down skin and hair follicle cell growth.

Insulin-sensitizing drugs like metformin can help with ovulation, weight loss, and lower testosterone in some women with PCOS.

Oral zinc sulphate reduces dark hair color in mice.

NcoA4 may have roles beyond helping control gene activity, possibly affecting cell behavior and stability.

Non-viral vectors show promise for safe and effective CRISPR/Cas9 gene editing in treating diseases.

Copper and iron cause keratin damage in hair by converting methionine to homocysteine.

Drugmakers are optimistic about targeting the Wnt pathway for new treatments despite past challenges.

NDP-MSH protects brain cells and reduces inflammation in Parkinson's disease by activating MC1R and involving Tregs.

Involucrin helps strengthen the inner parts of human hair.

Permed hair degrades faster and shows more damage after protease treatment compared to untreated hair.

The document reports findings on genetic research, including ethical concerns about genome editing, improved diagnosis of mitochondrial mutations, solving inherited eye diseases, confirming gene roles in epilepsy, linking a gene to aneurysms, and identifying genes associated with age-related macular degeneration.

Targeted therapies for lung cancer are effective but require careful management of side effects to benefit patients.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Melanocytes produce melanin; their defects cause vitiligo and hair graying, with treatments available for vitiligo.

Wild African goats have genetic adaptations for surviving harsh desert conditions.

Using combined treatments can help manage acne by targeting the bacteria and skin changes that cause it.

New drugs targeting the JAK-STAT pathway show promise for treating inflammatory skin diseases.

Insulin resistance is linked to PCOS and can lead to other health issues, but treatments like metformin can help manage symptoms.

Chromium supplements don't help with weight loss or improve hormone and metabolism issues in people with polycystic ovary syndrome.

Skin side effects from EGFR inhibitor cancer treatment can be managed effectively, often without stopping the medication.

Avoid chemical and physical damage to protect hair.

Hair stiffness is higher when it has more para-like cortical cells.

Sheep wool keratin solution safely and effectively promotes hair growth.

The article concludes that the wool follicle is a valuable model for studying tissue interactions and has potential for genetic improvements in wool production.
