The document concludes that hair is complex, with a detailed growth cycle, structure, and clinical importance, affecting various scientific and medical fields.
research Differentiation of Mouse Induced Pluripotent Stem Cells into a Multipotent Keratinocyte Lineage
Scientists turned mouse stem cells into skin cells that can grow into skin layers and structures.
research Characterization of a First Domain of Human High Glycine-Tyrosine and High Sulfur Keratin-associated Protein (KAP) Genes on Chromosome 21q22.1
Researchers mapped and categorized specific keratin-associated protein genes on human chromosome 21q22.1.
research Nutrition and Hair
Eating the right nutrients can improve hair health, but taking extra supplements usually doesn't help unless you have a deficiency.
research Physiologic functions of PP2A: Lessons from genetically modified mice
Mice studies show that Protein Phosphatase 2A is crucial for cell growth, development, and disease prevention.
research Learning from nudity: lessons from the nude phenotype
The Foxn1 gene mutation causes hairlessness and immune system issues, and understanding it could lead to hair growth disorder treatments.
research Control of pelage hair follicle development and cycling by complex interactions between follistatin and activin
Follistatin helps hair growth and cycling, while activin prevents it.
research Diet and hair loss: effects of nutrient deficiency and supplement use
Correcting nutrient deficiencies may help with hair loss, but the benefits of supplements without a deficiency are uncertain and could be harmful.
research Bone morphogenetic protein-2 (BMP-2) transactivates Dlx3 through Smad1 and Smad4: alternative mode for Dlx3 induction in mouse keratinocytes
BMP-2 activates the Dlx3 gene in mouse skin cells, important for hair and skin development.
research Large Scale Gene Expression Profiles of Regenerating Inner Ear Sensory Epithelia
Birds can regenerate inner ear cells using specific gene pathways, unlike mammals.
research Protein Kinase Cε, which Sensitizes Skin to Sun's UV Radiation–Induced Cutaneous Damage and Development of Squamous Cell Carcinomas, Associates with Stat3
Protein Kinase Cε increases skin sensitivity to UV damage and skin cancer risk.
research Improved Efficacy of Low-Dose Spironolactone and Metformin Combination Than Either Drug Alone in the Management of Women With Polycystic Ovary Syndrome (PCOS): A Six-Month, Open-Label Randomized Study
Taking low-dose spironolactone and metformin together works better for PCOS symptoms than either drug alone.
research Nutrition and hair
Certain groups may need vitamin supplements to improve hair health and prevent other health problems.
research The human type I keratin gene family: Characterization of new hair follicle specific members and evaluation of the chromosome 17q21.2 gene domain
The study identified and characterized new keratin genes linked to hair follicles and epithelial tissues.
research Age-induced hair greying - the multiple effects of oxidative stress
Hair greying is caused by oxidative stress damaging hair follicles and melanocytes.
research Influence of TRPV3 mutation on hair growth cycle in mice
The TRPV3 gene mutation affects hair growth by keeping mice in the growth phase longer, which could help treat hair loss.
research Effect of 5α-Dihydrotestosterone and Testosterone on Apoptosis in Human Dermal Papilla Cells
High levels of testosterone and 5α-DHT can lead to cell death in cells important for hair growth.
research Dihydrotestosterone Stimulates 5a-Reductase Activity in Pubic Skin Fibroblasts*
Dihydrotestosterone increases the activity of an enzyme in pubic skin cells that converts testosterone to dihydrotestosterone.
research Regulation of stem cell function by protein ubiquitylation
Protein ubiquitylation is crucial for controlling stem cell functions and could be targeted for cancer treatment.
research Tritiated Thymidine: Effect of Decomposition by Self-Radiolysis on Specificity as a Tracer for DNA Synthesis
Decomposed tritiated thymidine is less accurate for DNA tracing, and hair changes can indicate malnutrition.
