Prostate cancer cells can make their own androgens to activate the androgen receptor, and treatments like abiraterone may increase this ability, suggesting new therapies should target the entire steroid-making pathway.

Nerve signals are crucial for hair follicle stem cells to become skin stem cells and help in wound healing.

Testosterone is important for men's sexual function, may help some women's sexual desire, while other hormones and neurotransmitters also play complex roles in sexual behavior.

DNA profiling in forensics has improved, but predicting physical traits and ancestry from DNA has limitations and requires ethical consideration.

Auxin and ethylene hormones both work together and against each other to control plant growth.

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

The study found that in Latin America, ancestry varies by location, influences physical traits, and affects how people perceive their own heritage.

Stem cell niches are crucial for regulating stem cell behavior and tissue health, and their decline can impact aging and cancer.

SKPs are similar to adult skin stem cells and could help in skin repair and hair growth.

Frontal fibrosing alopecia is a hair loss condition in postmenopausal women, similar to lichen planopilaris, with ineffective treatments.

Microspheres about 1.5 micrometers in size can best penetrate hair follicles, potentially reaching important stem cells.

The research found that different types of fibroblasts are involved in wound healing and that some blood cells can turn into fat cells during this process.

TRPA1 is crucial for mechanical sensitivity in skin sensory neurons.

Vitamin D receptor interacts with certain dietary components to help prevent diseases and regulate hair growth.

The document likely offers guidance on treating a woman's excessive hair growth, considering her symptoms and obesity.

The Rotterdam Study aims to understand disease causes in the elderly and has found new risk factors and genetic influences on various conditions.

The study found that sweat glands contain different types of stem cells that help with healing and maintaining healthy skin.

Zinc oxide nanoparticles in sunscreen do not penetrate deep into the skin.

Polymeric nanoparticles show promise for treating skin diseases.

New nanofiber technology improves wound healing by supporting cell growth and delivering treatments directly to the wound.

Wnt signaling is crucial for pigmented hair regeneration by controlling stem cell activation and differentiation.

Mutations in the SRD5A3 gene cause a new type of glycosylation disorder by blocking the production of a molecule necessary for protein glycosylation.

Growing human skin cells in a 3D environment can stimulate new hair growth.

Apoptosis is essential for human skin development and forming a functional epidermis.

The guidelines advise against using testosterone and DHEA in women for most conditions due to safety and effectiveness concerns, but suggest considering testosterone for postmenopausal women with low sexual desire.

Wnt1/βcatenin signaling is crucial for heart repair after injury.

Dermoscopy is a useful tool for identifying features of skin conditions, but more research is needed to define its role in dermatology.

Ectodin integrates BMP, SHH, and FGF signals in developing ectodermal organs.

Fat cells help recruit healing cells and build skin structure during wound healing.

The timing of when the gene Bmal1 is active affects aging and survival, with its absence during development, not adulthood, leading to premature aging.
