research Bad Hair Day: Testosterone and Wnts
Testosterone can both promote hair growth and cause baldness by affecting hair growth signals.
research Gonadal Sex Steroids: Production, Action and Interactions in Mammals
The document concludes that sex hormones are crucial for mammalian reproduction, health, and behavior, and require more research for therapeutic use.
research Erasing the methyl mark: histone demethylases at the center of cellular differentiation and disease
Histone demethylases can change gene expression and may be linked to diseases like cancer.
research Sexual Hormones in Human Skin
Human skin makes sexual hormones that affect hair growth, skin health, and healing; too much can cause acne and hair loss, while treatments can manage these conditions.
research Advances in male hormone substitution therapy
New treatments for low male hormones improved sexual function and mood but had unclear risks, especially for older men.
research Four-amino acid segment in steroid 5 alpha-reductase 1 confers sensitivity to finasteride, a competitive inhibitor.
Four-amino acid part makes enzyme sensitive to finasteride.
research The 5alpha-reductase type 1, but not type 2, gene is expressed in anagen hairs plucked from the vertex area of the scalp of hirsute women and normal individuals
The gene SDR5A1 is found in scalp hair of both hirsute and normal individuals, but it does not explain differences in hair growth.
research Vitamin D Receptor: New Assignments for an Already Busy Receptor
The vitamin D receptor is involved in multiple body functions beyond calcium regulation, including immune response and rapid reactions not related to gene activity.
research Microarray analysis of androgenetic and senescent alopecia: Comparison of gene expression shows two distinct profiles
The conclusion is that androgenetic alopecia and senescent alopecia have unique gene changes, suggesting different causes and potential treatments for these hair loss types.
research Selected Abstracts
Parthenolide promotes hair growth in mice and may influence pathways related to male pattern baldness.
research Clinical features, with video documentation, of the original familial lewy body parkinsonism caused by α‐synuclein triplication (Iowa kindred)
The document describes a woman with familial Parkinson's disease due to a genetic mutation, showing severe symptoms and poor response to treatment, and suggests finasteride may help reduce symptoms in Tourette syndrome.
research Pharmacology of anabolic steroids
Anabolic steroids can build muscle and strength but have risks and need more research on their clinical benefits and side effects.
research Androgenetic alopecia and hair growth promotion state of the art: Present and future
Current research explores hair growth drugs, while future research aims for personalized treatments.
research The 5 Alpha-Reductase Isozyme Family: A Review of Basic Biology and Their Role in Human Diseases
The document concludes that the 5 alpha-reductase enzymes are important in steroid metabolism and related to various human diseases, with inhibitors used to treat conditions like male pattern baldness and prostate issues.
research 9 Role of 5α-reductase in health and disease
5α-reductase is essential for male sexual development and its inhibitors have potential in treating various conditions related to hormone action.
research Perspectives of Kennedy's disease
Kennedy's disease leads to muscle weakness and sensory issues, has no cure but manageable symptoms, and future treatments look promising.
research Is the “Comb Over” Dying? A Mouse Model for Male Pattern Baldness (Androgenic Alopecia)
The mouse model suggests male pattern baldness may be due to an enzyme increasing DHT and higher androgen receptor levels in hair follicles.
research Bioavailability File: Bicalutamide
Bicalutamide effectively treats prostate cancer but needs careful monitoring for side effects.
research Acne-associated syndromes: models for better understanding of acne pathogenesis
The document concludes that certain genetic mutations and dietary factors are involved in acne development, and treatments like isotretinoin and diet changes can help manage it.
research BLIMP1 Is Required for Postnatal Epidermal Homeostasis but Does Not Define a Sebaceous Gland Progenitor under Steady-State Conditions
BLIMP1 is essential for skin maintenance but not for defining sebaceous gland progenitors.
research Redefining hormone resistance in prostate cancer
The conclusion suggests that prostate cancer should be classified by castration status and that new therapies targeting androgen receptor signaling show promise.
research Pharmacologic Treatment of Polycystic Ovary Syndrome
The document concludes that various drugs can manage symptoms and metabolic issues in women with PCOS.
research Early embryonic exposure of freshwater gastropods to pharmaceutical 5-alpha-reductase inhibitors results in a surprising open-coiled “banana-shaped” shell
Certain drugs change freshwater snail shells to a "banana" shape.
research Insulin Resistance and Polycystic Ovary Syndrome
Insulin resistance is linked to PCOS and can lead to other health issues, but treatments like metformin can help manage symptoms.
research Sex differences in SARS-CoV-2 infection rates and the potential link to prostate cancer
Men, especially older ones with health issues like prostate cancer, may have worse COVID-19 outcomes and could benefit from therapies targeting male hormones.
research Hair: A Review of Prominent Scalp Hair Changes throughout a Females’ Life
Women's hair gets thinner and grayer as they age, with treatments available for hair loss and graying.
research Androgenic Alopecia: Cross-Talk Between Cell Signal Transduction Pathways
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.
research Inhibition of SARS-CoV-2 entry through the ACE2/TMPRSS2 pathway: a promising approach for uncovering early COVID-19 drug therapies
