Prolactin and melatonin affect the growth of Angora and Cashmere goat hair differently.

Animals that change color with the seasons mainly do so in response to daylight changes, but climate change is causing camouflage problems that may require evolutionary changes.

Human skin's melanocytes respond to light by changing shape, producing pigments and hormones, which may affect sleep patterns.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

Melatonin may help with sleep issues, depression, and cancer, but more research is needed.

The article concludes that better understanding gene regulation related to seasonal changes can offer insights into the mechanisms of seasonal timing in mammals.

Melatonin implants can change the seasonal prolactin levels and hair growth in adult cashmere goats but not in juveniles, and don't delay spring moult for better fiber harvesting.

The workshop highlighted the genetic links and psychological impacts of hair loss and skin disorders.

Melatonin treatment made ferrets grow their fur earlier and affected their breeding time.

Prolactin and melatonin can stimulate hair growth in Cashmere goat hair follicles, but melatonin may reduce follicle viability over time.

Immunizing goats against melatonin can temporarily change their cashmere growth cycles and increase fleece production.

Prolactin affects hair growth and skin conditions, and could be a target for new skin disease treatments.

Timing of light therapy affects horse coat growth, with photoperiod being crucial.

Hair growth is influenced by hormones and goes through different phases; androgens can both promote and inhibit hair growth depending on the body area.

Human skin can make serotonin and melatonin, which help protect and maintain it.

Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.

Androgens can both stimulate and cause hair loss, and understanding their effects is key to treating hair disorders.

Prolactin affects hair growth cycles and can cause early hair follicle regression.

Melatonin implants and long daylight hours alter the timing of hormone release and hair growth in mouflon sheep.

Sex hormones, especially estradiol, can change chicken feather shapes and colors.

Melatonin may benefit skin health and could be a promising treatment in dermatology.

Melatonin helps regulate hair growth and protects the hair follicle from stress.

Mouflon rams mature gradually with changes in body, horns, and hormones linked to age and seasons, reaching full sexual maturity well after puberty.

Prolactin affects the production of different keratins in human hair, which could lead to new treatments for skin and hair disorders.

Prolactin slows down hair growth in mice.

The control system for hair growth cycles is not well understood and needs more research.

Goat reproductive activity and coat growth are affected by light and temperature, with temperature altering prolactin levels and hair growth, but not melatonin or estrus onset.

Researchers found genes that control hair color and growth change before the visible coat color changes in snowshoe hares.

Genes related to pigmentation, body rhythms, and behavior change during hares' seasonal coat color transition, with a common genetic mechanism in two hare species.

OCT binds strongly to hair sheath cells and may affect skin and hair growth with fewer side effects than vitamin D3.
