This study found that blocking autophagy in Atg7-deficient mouse hair keratinocytes altered the molecular composition of hair shafts by increasing the abundance of proteins involved in protein turnover while keratins remained unchanged, highlighting autophagy's role in reducing non-cytoskeletal protein concentrations in hair.

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 demonstrated that Forsythiaside A protected against oxidative stress in both cell models and a mouse model of liver damage, suggesting its potential as a liver-protective agent.

This review discusses how dysfunction in keratinocyte adhesion affects skin integrity and conditions like alopecia and keratoderma, highlighting the roles of intercellular junctions, and reports no new clinical results.

In this study, researchers using a Treg-specific HuR-deficient mouse model found that the RNA-binding protein HuR is crucial for stabilizing Foxp3 mRNA, affecting Treg function and immune regulation, with HuR disruption leading to impaired Foxp3 expression and potential autoimmune dysfunction.

This study found that patients with alopecia areata had significantly lower serum levels of autophagy-related protein 5, indicating a potential role of dysfunctional autophagy in the disease's pathogenesis.

In this study, XZYFD, a Traditional Chinese Medicine formulation, was found to improve androgenetic alopecia in a testosterone-induced mouse model by promoting hair regrowth, restoring follicular morphology, and modulating androgen metabolism, MAPK signaling, and lipid metabolism pathways, suggesting potential benefits for patients with metabolic dysfunction.

p14ARF and p16Ink4a cause hair follicle stem cell aging and dysfunction.

This study found that Fgf5 mutant mice exhibited longer hair, particularly in males, likely due to a prolonged anagen phase in the hair cycle.

This correspondence discusses bias in expert medical testimony within workmen's compensation cases, emphasizing the author's objective approach, but provides no new empirical findings.

This review discusses the essential roles and complex regulation of PP2A in various physiological processes and reports no clinical results; the authors highlight the need for further mouse model research to explore PP2A's therapeutic potential.

This study found that thyroxine modulates peripheral molecular clock gene expression in human hair follicles, which may have implications for treating clock-related diseases in patients with thyroid dysfunction.

This study found that oxidative damage is present in the mitochondria of PolG mice, which exhibit premature aging-like phenotypes due to mitochondrial dysfunction.

This review explores the role of Granzyme B in autoimmune skin diseases and highlights its potential as a therapeutic target due to its involvement in impaired barrier function and inflammation.

This study on adult male rats found that finasteride treatment led to molecular changes linked to erectile dysfunction, while withdrawal from the drug did not alter these parameters.

Hair follicle stem cells and mitochondria are key for hair growth, and targeting their activity could lead to new hair loss treatments.

This review provides an overview of biotin's role in metabolism and the consequences of deficiency but reports no new clinical findings; it highlights that intestinal bacteria usually meet biotin needs.

This review discusses the role of biotin in metabolism and its dietary requirements, but provides no new experimental findings.

This review examines the role of retinoic acid synthesis in hair follicles and sebaceous glands, focusing on its localization and function during normal and disease states, but reports no new results.

Metabolic issues may trigger lymphocytic cicatricial alopecia, and treatments targeting these issues could help.

In this study, researchers found that Ectoin, derived from halophilic bacteria, can mitigate stress-related skin damage by reducing cortisone's inhibitory effects on essential skin proteins and decreasing UVB-induced glucocorticoid activity, highlighting its potential as a preventative agent for stress-induced skin issues.

This study explores how EGFR signaling impacts skin inflammation and follicular integrity during hair eruption, aiming to identify druggable pathways to mitigate skin inflammation in cancer patients receiving EGFR inhibitors.

This study found that tight junctions extend to the most superficial layer of the stratum granulosum in human skin, challenging previous claims of their limited presence in the epidermis.

This summary outlines the essential roles and recommended daily intakes of biotin, while discussing consequences and mechanisms of deficiency, but presents no new research findings.

This review discusses the heterogeneity of dermal fibroblasts in healthy mouse and human skin and reports no clinical results; the authors highlight potential insights into physiological and pathological wound healing.

The researchers reported increased ubiquitination of proteins such as the insulin receptor in CYLD cutaneous syndrome skin tumors, suggesting that CYLD dysfunction may affect protein secretion and signaling processes.

This study reviews the regulatory mechanisms and molecular processes governing stem cell activity in hair follicles, highlighting their roles in hair regeneration and potential implications for treating hair and skin disorders.

This review describes bioengineering strategies to mimic the natural cell microenvironment in vitro, emphasizing the novel approach of using cell-synthesized extracellular matrix as a scaffold for engineering functional 3D tissues, while highlighting the limitations of exogenous scaffolds in tissue engineering.
