This study identified a new type II cytokeratin, named K6hf, exclusively expressed in the companion layer of the human hair follicle, distinguishing it from other keratins and suggesting a unique biochemical role.

This study suggests that finasteride's effect on promoting hair growth in men with androgenetic alopecia may be due to its inhibition of 5aR2 localized in hair follicles.

This study identified a cluster of genes on chromosome 17 related to hair keratin-associated proteins, including 37 genes forming seven multigene families, localized in the hair shaft's upper cortex.

This background review discusses alopecia areata, highlighting the role of CD8+NKG2D+ T cells in hair follicle pathogenesis, and notes that the exact mechanisms causing hair loss remain unclear.

This study found that sebaceous glands predominantly exhibit oxidative activity of the type 2 17β-hydroxysteroid dehydrogenase isozyme, which is not inhibited by 13-cis retinoic acid.

This review discusses the distinct clinical and psychological aspects of adult female acne and reports no new clinical results, highlighting the need for a comprehensive management approach.

This study found that certain compounds from Chaga mushrooms stimulated the proliferation of human hair follicle cells more effectively than minoxidil, suggesting potential for hair-growth treatments.

This study found that 5α–reductase activity is higher in infrainfundibular keratinocytes compared to interfollicular epidermal keratinocytes, suggesting a potential role in acne-related follicular changes.

In this study, researchers found that serum dihydrotestosterone levels were significantly lower in individuals with Type 2 Diabetes compared to healthy controls, with 90% of diabetics displaying subnormal levels.

This study identifies a bipotent stem cell in adult hair follicles that self-renews and contributes to dermal sheath and papilla cell populations, potentially aiding hair regrowth after injury, disease, or aging.

This study found that squamous cell carcinomas from hair follicle stem cells are more prone to epithelial to mesenchymal transition and metastasis than those from interfollicular epidermis, due to distinct chromatin landscapes.

This study found that sympathetic nerves and arrector pili muscles form a niche that modulates hair follicle stem cell activity, revealing their role in hair follicle regeneration.

This study discovered nine human type I hair keratin genes, including a transcribed pseudogene, in a 190 kbp genomic region, revealing three gene subclusters based on sequence homologies.

This study identifies six novel keratin genes from the chromosome 17q21.2 region, suggesting their association with hair follicles, while all 27 keratin genes in the domain have been characterized transcriptionally.

This study found that overexpression of parathyroid hormone-related protein in mice resulted in 30–40% shorter hair due to premature transition into the catagen phase of the hair cycle.

This study found that SRD5a-3 is a highly efficient enzyme for converting hormones into androgens, with dutasteride being a much more potent inhibitor of SRD5a-3 than SRD5a-2.

This study found that PNU 157706 is a highly potent inhibitor of human 5α-reductase enzymes, showing a stronger and longer-lasting antiprostatic effect in rats compared to finasteride.

This study suggests that ROXYs and reactive oxygen species are likely involved in the signaling pathways plants use to respond to nitrate deprivation.

This study suggests that the absence of alpha5(IV)/alpha6(IV) chains in certain subepidermal basement membrane spots may relate to interactions with melanocytes in human skin.

This study found that serine 44 in the N-terminal head domain of keratin 17 is phosphorylated in response to various stimuli affecting skin keratinocyte growth, linking K17 up-regulation with growth and stress responses in skin epithelium.

This paper reports on the structural characteristics of α-type filaments in the inner root sheath cells of guinea pig hair follicles without presenting new clinical findings.

In this mouse study, NF-κB was shown to play a role in hair follicle cycling and morphogenesis, with specific activity patterns differing by hair type and involving noncanonical signaling for zigzag hair bending.

In this study of patients with androgenetic alopecia, botulinum toxin type A was found to significantly increase hair counts and improve hair density and coverage, with enhanced results observed when combined with oral finasteride, revealing a safe and effective treatment approach without adverse effects.

This study presents the first reported case of kerion-type scalp mycosis caused by Aspergillus protuberus, emphasizing the importance of mycological examination when diagnosing unusual scalp infections, especially in children.

In this study, researchers found that ginsenoside Re from Panax ginseng increased hair shaft length and duration in mice, comparable to minoxidil, by modulating TGF-β signaling pathways.

This study suggests that specific combinations of human type I and II hair keratins, particularly K35-K85 and K36-K81, have distinct in vitro assembly properties that are significant for macrofibril formation.

This study found that neurotrophin-4 regulates Cav3.2 T-current expression in D-hair neurons via TrkB receptor activation, highlighting its role in mechanosensitive function.

This study reports that long-term use of finasteride does not affect bone mineral density in men with benign prostatic hyperplasia over a four-year period.

This study found that trans-3,4'-Dimethyl-3-hydroxyflavanone reduces active TGF-beta2 levels in human keratinocytes, suggesting it may enhance hair growth by suppressing the TGF-beta2 activation pathway.

This case report presents the first known instance of combined polycystic ovary syndrome and autoimmune polyglandular syndrome type 2 in a patient, exploring potential mechanisms for their interrelation.
