This study observed similar D2-40 expression in scarring and nonscarring alopecia, with some increase in scarring cases, suggesting possible Fos-dependent mechanisms, though more research is needed for definitive conclusions.

In this study, PGD2 was shown to increase testosterone production in human keratinocytes through reactive oxygen species, suggesting potential benefits of antioxidants like N-acetyl-cysteine for AGA patients.

This study observed that low serum ferritin and vitamin D levels may contribute to diffuse hair loss in women.

This study found that prostaglandin D2 reduced proliferation in bulge resident K15+ stem cells but not in other K15+ progenitor cells, suggesting differential impacts on hair follicle stem cell niches.

This study found that low serum ferritin and vitamin D2 levels are associated with hair loss in females with chronic telogen effluvium and female pattern hair loss, suggesting potential benefits of screening and supplementation.

New app improves storm surge predictions; advances in baldness treatment show potential but require time.

This review discusses advances in molecular biology and genetics related to androgenetic alopecia and reports no new clinical results.

This study suggests that the Anetholea anisita extract improved scalp health by increasing specialized pro-resolving mediators and reducing pro-inflammatory markers, leading to decreased dandruff and enhanced hair brightness in dandruff sufferers.

This review highlights that castor oil has potential dermatological uses, including enhancing hair luster, reducing hyperpigmentation, and improving skin hydration and elasticity, although rare side effects like contact dermatitis occur, necessitating further research to confirm its effectiveness in these applications.

This abstract reviews hereditary vitamin D-resistant rickets, a rare genetic condition causing severe early childhood rickets, and reports no new results; effective treatment typically requires high doses of calcium to address hypocalcemia and secondary hyperparathyroidism.

This study identified CXXC5 as a key mediator of hair loss induced by PGD2 and DHT via suppression of the Wnt/β-catenin pathway, with implications for potential therapeutic targets.

This case study describes a 21-year-old man who experienced a hemorrhagic stroke potentially linked to finasteride and minoxidil use for androgenic alopecia, emphasizing the need for thorough medication history in young stroke patients.

This review discusses the roles of prostaglandins in hair loss and highlights their potential as targets for new alopecia treatments, but reports no new clinical findings.

This study found that PCOS women with COVID-19 had lower ACE2 levels and higher insulin resistance, suggesting increased cardiovascular risk.

In this study on mice, intensive stress through methods like resiniferatoxin injections and physical restraint was found to inhibit hair follicle growth, with the mechanism involving the sympathetic nervous system and the cAMP signaling pathway in hair follicle stem cells.

This study found that vitamin C increased the survival, proliferation, and hair-regenerative potential of adipose-derived stem cells through the MAPK pathway and enhanced hair growth in mice.

This review discusses the roles of prostaglandins in the nervous system and their therapeutic potential for neurological diseases, noting their complex interactions with immune cells and signaling pathways.

This study reports the crystal structure and geometric parameters of a modified Finasteride derivative, highlighting significant differences in dihedral angles compared to its solvated analog and computational models.

This study found that prostaglandin D2 promotes androgen receptor and AKT signaling in human dermal papilla cells through the DP2 receptor, potentially contributing to androgenetic alopecia.

PGD2 stops hair growth and is higher in bald men with AGA.

This review examines the impact of vitamin D signaling in extraskeletal tissues and notes that expected benefits from animal and cell studies have not been consistently replicated in human clinical trials.

This study found that PGD2 inhibits hair follicle regeneration in mice through the Gpr44 receptor, suggesting that blocking PGD2 or Gpr44 may enhance skin regeneration after wounds.

This study identified several compounds from traditional Chinese medicines that may inhibit prostaglandin D2 synthase, potentially providing promising candidates for treating androgenic alopecia with minimal adverse skin reactions.

This study suggests that the expression of the DP2 receptor is higher in balding scalp cells and that its knockdown could inhibit the transition to the catagen phase in cultured human hair follicles, potentially counteracting hair growth inhibition associated with male pattern baldness.

This study assessed Ageratum conyzoides gel's efficacy in reducing hair loss and improving quality of life in adults with pattern baldness, finding that it decreased temporal recession and improved hair-related distress scores, with a significant reduction in 5α-reductase expression and PGD2 release in vitro.

This study found that patients with myotonic dystrophy types 1 and 2 often exhibit skin abnormalities, which correlate with genotype severity and serum vitamin D levels, and suggest premature aging.

This article describes the immunofluorescence tomography method to achieve high-resolution 3-D reconstruction of epithelial tissues and reports no clinical results.

This study found no significant correlation between vitamin D levels and disease severity in alopecia areata patients, highlighting the need for further research on vitamin D supplementation's effects.

Gene variation affects prostate issues and hair loss.

This study identified novel 4-Amino-2H-benzo[h]chromen-2-one analogs as potent androgen receptor antagonists that show strong antiproliferative activity against prostate cancer cells, suggesting them as potential lead compounds for therapy development.
