Zinc is essential for plant growth and human health, but many soils lack enough zinc, affecting crops and potentially leading to health problems.

Skin health and repair depend on the signals between skin stem cells and their surrounding cells.

The document concludes that scalp health is influenced by complex factors affecting sebaceous glands, including hormones, aging, and various substances.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

Neurohormones help control skin health and could treat skin disorders.

Ishige sinicola extract helps bone-building cells grow and mature, which could aid in treating osteoporosis.

Sex hormones affect brain injury differently in males and females.

Blocking Wnt/β-catenin signaling with EGF receptor is necessary for proper hair growth.

Activating TSPO helps protect the retina from damage caused by high eye pressure in glaucoma.

The developed model can predict effective 5-alpha-reductase enzyme inhibitors.

Wnt-signaling is regulated differently in skin cells and immune responses during wound healing.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.

Maintaining DNA health in stem cells is key to preventing aging and tissue breakdown.

A new protein was made to detect specific skin cell growth receptors and worked in normal skin but not in skin cancer cells.

The protein StAR is found in 17 different organs and can affect hair loss and brain functions, but its full role is not yet fully understood.

A natural steroid in the body may protect against eye damage in glaucoma.

Keratinocytes show more TGF-β system activity and collagen production as they age, which might affect wound scarring.

DHT affects bone growth by altering gene activity in osteoblasts, potentially complicating steroid use.

Etifoxine, an anxiety drug, can lessen brain inflammation and cognitive issues in mice, partly by increasing production of protective brain steroids.

Mutations in the enzyme don't significantly change how it binds to its specific substances.

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.

Nutraceuticals that promote hair growth do not reduce tamoxifen's effectiveness in breast cancer treatment.

Glycogen metabolism is important for energy and processes in human hair follicles, and hair follicles may produce glucose from lactate.

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

Melatonin receptors, found in many body parts, can help treat various diseases like depression and diabetes due to their effects on inflammation, tumor progression, sleep disorders, and body mass regulation.

We now understand more about what causes acne and this could lead to better, more personalized treatments.

Melatonin helps hair grow by activating a specific signaling pathway.

Melasma's causes include genetics, sun exposure, hormones, and oxidative stress, and understanding these can help create better treatments.

BMPR1a-ECD reduces wrinkles much more effectively than retinoic acid.

Vitamin A affects hair loss and immune response in alopecia areata.
