The mutated hairless gene causes hair loss by acting as a new type of corepressor affecting thyroid hormone receptors.

Hair stem cell regeneration is controlled by signals that can explain different hair growth patterns and baldness.

Hormone treatments in transsexual individuals reduce hair growth and oil production in male-to-females and increase them in female-to-males.

Different types of skin cells have unique genetic markers that affect how likely they are to spread cancer.

Mammalian organs regenerate using stem cells and cell plasticity, but this ability declines with age.

The document concludes that the exact way alcohol causes harm to fetal development is unknown, but it significantly affects nutrient transport to the fetus and a safe level of alcohol during pregnancy is not determined.

Flutamide is more effective and has fewer side effects than spironolactone for treating hirsutism.

Accurate diagnosis and effective oral treatment are key to managing tinea capitis and preventing its spread.

TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

Humans lost body hair relatively recently in evolution.

Effective treatments for male pattern baldness include oral finasteride and topical minoxidil, while topical minoxidil is best for female pattern baldness.

Estrogen therapy can reduce skin aging but has cancer risks.

TNF alpha in skin cells causes weight loss, hair and fat issues, and skin inflammation in mice.

Researchers developed promising agents for prostate cancer imaging, with the best one showing high potential for clinical use.

The WNT signaling pathway is important in many diseases and targeting it could offer new treatments.

K_ATP channel gene mutations are linked to heart diseases, but more research is needed to understand the connection and treatment potential.

Dextran sulfate was found to be toxic and ineffective for treating HIV.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

Vitamin D is important for skin health and may affect conditions like psoriasis and hair loss, but more research is needed to understand its role fully.

Periodontal ligament stem cells show promise for regrowing tissues but require more research for safe, effective use.

Eating less sugar, milk, and saturated fats and more vegetables and fish may help treat and prevent acne.

The HR protein helps hair grow by blocking a hair growth inhibitor, aiding in hair follicle regeneration.

Estrogen loss during menopause worsens skin health, but hormone replacement therapy may improve it, though more research is needed.

Exosomes could potentially enhance tissue repair and regeneration with lower rejection risk and easier production than live cell therapies.

The conclusion is that PCOS is caused by ovarian sensitivity to hormones and disrupted hormone control, possibly due to ovarian factors, and more research is needed.

Modulating BMP activity changes the number, size, shape, and type of ectodermal organs.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Obesity worsens PCOS symptoms, and PCOS may lead to more weight gain; managing both requires a holistic approach that includes mental health.

Low doses of some substances can be beneficial, while high doses can be harmful or toxic.
