Keratin 15 expression in skin cells is regulated by two mechanisms involving PKC/AP-1 and FOXM1.

TrichoTech™ may help hair growth and skin repair by increasing fibroblast growth and activity.

Increasing EGR1 levels makes hair root cells grow faster.

Researchers created immortal human skin cells with constant testosterone receptor activity to study hair loss and test treatments.

Traditional Chinese medicinal foods may help manage long-term post-COVID symptoms.

MicroRNA-214 is important for skin and hair growth because it affects the Wnt pathway.

An imbalanced gut and lack of biotin can cause hair loss in mice.

Apoptosis is crucial for healthy skin and treating skin diseases.

Nuclear shape and chromatin changes affect gene expression in skin cell differentiation.

Blocking a specific enzyme can reduce the negative impact of stress hormones on hair growth cells.

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.

Non-coding RNA boosts retinoic acid production and signaling, aiding regeneration.

The nucleus is key in controlling skin growth and repair by coordinating signals, gene regulators, and epigenetic changes.

The Siah1 and Siah2 genes are active in mouse skin development and hair growth, especially right after birth.

Certain miRNAs might be involved in a hair loss condition called frontal fibrosing alopecia and could possibly help in its diagnosis.

The study found that sweat glands normally suppress immune responses, but this is disrupted in certain skin diseases, possibly contributing to their development.

Researchers created human cells that can turn into sebocytes, which may help study and treat skin conditions like acne.

Finasteride helps female-pattern hair loss.

Mice without the vitamin D receptor have bone issues and other health problems, suggesting vitamin D is important for preventing various diseases in humans.

The vitamin D receptor is involved in multiple body functions beyond calcium regulation, including immune response and rapid reactions not related to gene activity.

TGF-β is crucial for tissue repair and can cause diseases if not properly regulated.

Eph receptors and ephrins may be promising targets for treating diseases, but more understanding is needed for effective and safe therapies.

Sulforaphane from broccoli can help protect skin from sun damage.

Capsaicin, found in chili peppers, can slow down hair growth by affecting skin cells and hair follicles.

Vitamin D has potential benefits for cancer prevention, heart health, diabetes, obesity, muscle function, skin health, and immune function, but clinical results are mixed and more research is needed.

Smoking harms the skin, causing early aging and increasing cancer risk, but stopping smoking can improve skin health.

The article concludes that while we understand a lot about how melanocytes age and how this can prevent cancer, there are still unanswered questions about certain pathways and genes involved.

Human hair follicles produce and respond to erythropoietin, helping protect against stress.

Cancer can hijack the body's cell repair system to promote tumor growth, and targeting this process may improve cancer treatments.
