Sex and stress steroids quickly change brain cell structures in the hippocampus.

Retinoic acid can either maintain stem cells or make them specialize, depending on the cell type.

SARMs show promise but need more evidence to prove they're better than traditional androgens.

Hair follicle growth and fiber production in animals are influenced by chemical signals, proteins, pigmentation, genetics, and nutrients.

Androgens are important for normal ovarian function and estrogen production, but may not be the main cause of follicle death.

Genetic defects in the glucocorticoid receptor gene can cause conditions with abnormal sensitivity to stress hormones, and other factors may also affect this sensitivity.

The conclusion is that while oral contraceptive pills are effective for PCOS-related high androgen levels, new treatments with fewer side effects are needed.

Non-liganded Vitamin D Receptor is crucial for healthy skin and hair.

Androgens like testosterone increase colon muscle contractions by affecting calcium pathways.

Removing part of the vitamin D receptor stops vitamin D from working properly.

Paxillin may help manage androgen-related disorders like PCOS by stabilizing androgen receptor proteins.

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.

Eating vitamin A affects hair growth and health by changing cell signals in mice.

1α,25-dihydroxyvitamin D3 directly affects cartilage growth and development.

Cocaine impairs male sexual behavior and alters testosterone metabolism in the brain.

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 protein called FERONIA helps control root hair growth in response to cold and low nitrogen by activating nutrient-sensing pathways in a plant called Arabidopsis.

G-1 promotes hair growth in female mice by activating specific signaling pathways.

Testosterone may worsen hair loss by affecting hair growth signals, while different prostaglandins can either hinder or promote hair growth.

Estrogen therapy can reduce skin aging but has cancer risks.

PGD2 increases androgen receptor activity in hair cells, which could be targeted to treat hair loss.

The conclusion suggests that prostate cancer should be classified by castration status and that new therapies targeting androgen receptor signaling show promise.

New treatments for prostate cancer and BPH show promise, including novel compounds that target hormone synthesis and response.

Male hormones may play a role in the development of heart disease, and more research is needed to understand their effects.

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

Natural products show promise for treating diseases but need more research to understand and use them effectively.

Oestrogens help maintain healthy skin, heal wounds, and may protect against skin aging and cancer.

Dermal EZH2 controls skin cell development and hair growth in mice.

Testosterone can both promote hair growth and cause baldness by affecting hair growth signals.

Dermal EZH2 controls skin cell growth and differentiation in mice.
