Lifestyle changes can improve body composition, excess male hormone levels, and insulin resistance in women with PCOS.

High levels of male hormones, insulin resistance, and obesity are closely linked and worsen polycystic ovary syndrome, but more research is needed to improve treatments.

The hedgehog signaling pathway is crucial for hair growth but not for the initial creation of hair follicles.

Hair follicle development and microbes help regulatory T cells gather in newborn skin.

Researchers found 19 genes important for root hair growth in a plant called Arabidopsis.

Men are more likely to have severe COVID-19 cases and fatalities than women due to factors like lifestyle, aging, and biological differences.

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

Capsaicin, found in chili peppers, can slow down hair growth by affecting skin cells and hair follicles.

A substance called DKK-1 increases in balding areas and causes hair cells to die when exposed to DHT.

Blocking COX, especially COX-2, in the skin can reduce inflammation and pain and may help prevent skin cancer.

Stress-related substance P may lead to hair loss and negatively affect hair growth.

DrugNet effectively identifies new uses for existing drugs and may save resources in drug development.

Tributyltin exposure causes sex changes, sterilization, and decline in the snail Ocinebrina aciculata, risking its extinction.

Understanding hair growth involves complex interactions between molecules and could help treat hair disorders.

The document concludes that more research is needed to better understand and treat primary cicatricial alopecias, and suggests a possible reclassification based on molecular pathways.

Keratinocytes help heal skin wounds by interacting with immune cells and producing substances that kill pathogens.

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

The niche environment controls stem cell behavior and plasticity, which is important for tissue health and repair.

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

Sonic hedgehog signaling is crucial for hair growth and maintaining hair follicle identity.

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

Adam10 enzyme is crucial for healthy skin and proper Notch signaling.

Fat-derived stem cells show promise for skin repair and reducing aging signs but need more research for consistent results.

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

Macrophages help heal nerves by aiding the maturation of Schwann cells and are important for nerve repair.

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.

Damage to skin releases dsRNA, which activates TLR3 and helps in skin and hair follicle regeneration.

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

Understanding how cells die in the skin is important for treating skin diseases and preventing hair loss.

Vitamin D has potential benefits for cancer prevention, heart health, diabetes, obesity, muscle function, skin health, and immune function, but clinical results are mixed and more research is needed.
