This article describes the structure and components of hair cuticle cells and their intercellular junctions but reports no new clinical results.

This study found that the keratin expression in basal cell carcinoma resembles that of the pilosebaceous apparatus, with uniform presence of certain keratins in all cases.

This study used proteomic techniques to analyze human hair proteins, revealing keratin heterogeneity and identifying posttranslational modifications, such as cysteine trioxidation and methylation.

This review discusses Cronkhite-Canada syndrome, highlighting a relatively mild case and suggesting that it may be a more benign and possibly reversible condition with treatment, but reports no new clinical results.

This study found that matriptase, a membrane serine protease, is crucial for maintaining multiple types of epithelial tissues in mice, with its absence leading to severe organ dysfunction and increased permeability.

This study suggests that the downregulation of BBS7 in occlusal hypofunctional periodontal ligament impairs Shh signaling, which is essential for maintaining periodontal ligament homeostasis.

This article discusses the complex aetiology, diagnostic criteria, and challenges in diagnosing polycystic ovary syndrome, but does not report new clinical findings.

This study found that dysregulation of the folliculin-p0071 interaction may lead to changes in cell adhesion and signaling, contributing to conditions like emphysema and renal cell carcinoma.

This study found that sulfated CCK octapeptide reduces psoriasis-like skin inflammation in mice, suggesting a new pathophysiological role for CCK in regulating epidermal inflammation.

This case report describes a rare instance of nevus comedonicus with a multi-dermatomal unilateral pattern along the lines of Blaschko, treated unsuccessfully with topical tretinoin and oral retinoids.

This article reviews the anatomical complexity and developmental aspects of hair follicles for analyzing abnormalities, but reports no new clinical findings.

This study found that a novel nano-engineered platform, PCA, significantly promoted hair regeneration in an androgenetic alopecia mouse model by enhancing angiogenesis and hair follicle stem cell proliferation, showing promise for future hair regrowth treatments.

This study found that distinct glycoconjugate expression patterns in human hair follicle cells suggest complex carbohydrate metabolism, revealing a unique sugar moiety in outer root sheath cells not present in other keratinocytes.

In a cell-free test setting, this study found that a novel saw palmetto extract effectively inhibited the 5α-reductase type II enzyme, showing promising bioactivity comparable to finasteride for promoting prostate health.

This study found that the new cocrystal formulation KET-PABA improved the antimycotic efficiency of ketoconazole and induced an anti-inflammatory response without causing skin sensitization in mice.

In laboratory settings, this study suggests that Serenoa repens and N-acetyl glucosamine with milk proteins may promote hair follicle vascularization through specific cellular interactions and actions.

This study documents dominant transmission and complete penetrance of uncombable hair syndrome in a family, despite the father lacking visible abnormalities.

In this study, researchers found that overexpression of CRABP2 enhanced the proliferation of dermal papilla cells in Hu sheep through activation of the Wnt/β-catenin pathway, even when the pathway was inhibited.

This study found that Ecklonia cava polyphenols increased human dermal papilla cell proliferation and extended hair shaft length in vitro and ex vivo, suggesting potential as a therapeutic candidate for hair loss.

This review discusses the roles of epithelial-mesenchymal interactions and dermal papilla in hair follicle growth and cycling, but it reports no new clinical results.

This study investigated autophagy activator ICP5249 and found it promotes hair growth by enhancing cell proliferation and autophagy-related markers in human dermal papilla cells and hair follicles, with AMPKα playing a regulatory role, suggesting its potential as a hair growth ingredient.

This study reported that complex therapy involving pharmaceutical treatment and scalp application of biomimetic peptides was found to be effective in improving hair and scalp conditions in patients with telogen hair loss and androgenetic alopecia, compared to a control group receiving only pharmaceutical treatment.

This study found that the carbohydrate-based excipient β-cyclodextrin forms a stable inclusion complex with the active ingredient of Minoxicapil®, potentially enhancing its formulation for hair-loss treatment, and in vitro assays suggest improved proliferation of DPC cells, supporting its use in topical treatments.

This study found that the acyl-CoA binding protein is essential for the production of very long chain free fatty acids in the stratum corneum and maintaining normal epidermal barrier function in mice.

Keratin-associated proteins are crucial for hair strength and structure.

Keratin in mouse hair follicles is complex and plays specific roles.

This study found that cystatin M/E strongly inhibits human cathepsin V and cathepsin L via distinct non-overlapping sites, suggesting an important role in human epidermal differentiation and hair follicle morphogenesis.

This case study found that a 7-year-old girl's crystalline cataract had sulfur-containing amino acids likely cystine, and was associated with abnormal hair conditions.
