This study found that dihydrotestosterone induced hair loss and changes in hair morphology in male C57BL/6 mice, effects that could be partially reversed by the AR antagonist bicalutamide.

This study demonstrated that dermal papilla cells are molecularly distinct from fibroblasts and identified many novel molecules, including a new member of the CTGF protein family.

This study found that while autonomous Sema3A expression limited keratinocyte migration and delayed wound healing, non-autonomous application of recombinant Sema3A with EGF enhanced wound repair in mice.

This study found that carvone, a plant-derived compound, decreases melanin content and inhibits melanoma cell proliferation through the cAMP pathway, suggesting potential benefits for treating melanomas and other hyperpigmentation disorders.

In this study, topical application of α-methylspermidine during the telogen phase in mice induced hair growth by increasing the polyamine pool and mimicking the anagen phase's characteristics.

This report describes an outbreak of catheter-related infections by ESBL-producing E. coli in calves at an animal teaching hospital, highlighting the risk of these strains becoming nosocomial and increasing mortality and antibiotic use.

The researchers reported that applying proteolytic enzymes to mice skin negatively affected hair follicles, leading to degeneration and potential impairment of stem cells from the bulge area.

This study found that NKIRAS2 expression affects skin tumor suppression and HRAS-driven transformation in mice, indicating its role in carcinogenesis depends on expression level and cellular context.

This study applied a prediction model based on five SNPs to Russian males with male pattern hair loss, finding a significant association between the AR genomic region and high dihydrotestosterone levels in these patients.

This study observed that Wnt5a mRNA expression in mice correlates with the hair cycle and inhibits hair follicle growth by antagonizing the Wnts pathway.

In this case report, the authors describe a partial androgen insensitivity syndrome patient with a novel AR gene mutation, highlighting challenges in gender assignment decisions for infants with partial AIS.

This study found that SMAD2 overexpression in human hair follicle stem cells promoted differentiation and apoptosis while inhibiting proliferation, and Smurf2 upregulation limited mouse wound healing by suppressing the SMAD2/NANOG/DNMT1 axis.

This study found that polymorphism of the SHBG gene (rs1799941) is associated with an increased risk of Polycystic Ovary Syndrome in Iraqi women.

This study mapped copy number variations in Chinese fine-wool sheep, identifying regions linked to important traits like milk production and growth, and highlighting a strong selection signal at the RXFP2 gene.

This study constructed a genomic map of copy number variations in fine-wool sheep, revealing their potential impact on traits like growth, nutrient metabolism, and susceptibility to selection pressures.

This study explored how long non-coding RNA mediates the effects of FGF5 on the hair follicle development and villus growth of Liaoning cashmere goats.

This research successfully established a novel mouse model for anagen effluvium using BrdU treatment, which induced hair loss and pathological changes mimicking human symptoms.

This section presents 70 multiple choice questions designed for haematology specialist trainees, covering complex clinical cases and their likely diagnoses, adverse events, and management advice.

This article presents a collection of 70 multiple choice questions designed to assist haematology and core medical trainees with diagnostic and management skills, but it provides no new clinical findings.

This summary presents papers from the British Society for Dermatopathology but does not report new scientific findings or results.

This article discusses the structure of the human type II 5 alpha-reductase gene and reports no new experimental results.

This study details the isolation and characterization of the human type II 5 alpha-reductase gene, which may play a role in male pseudohermaphroditism, prostate cancer, and benign prostatic hyperplasia.

This study found that NGAL expression increased in calcium-induced keratinocyte differentiation in vitro and was highly elevated in psoriasis-like skin conditions and skin cancers, suggesting a role in skin hyperplasia and homeostasis.

This study found that the XEDAR receptor can activate the non-canonical NF-kB pathway involving p100 processing, which is regulated by interactions with TRAF proteins and specific kinases.

This study found that integrin-linked kinase is crucial for various epidermal functions, including differentiation and barrier formation, and also plays a previously unreported role in melanocyte development and function.

This study found that among patients with Down syndrome, those with alopecia areata may have increased antiperoxidase antibodies, possibly linked to hypothyroidism.

This review summarizes the cell type distribution and functional significance of human keratins, emphasizing their roles in tumor diagnosis and potential clinical applications, and reports no new clinical findings.

In this study, researchers identified 18 genetic associations with scalp and facial hair traits in Latin Americans, including novel loci for hair greying and balding, with implications for understanding hair evolution.

This study found that thymus transplantation in infants with FOXN1 deficiency led to T-cell reconstitution and functional immunity, resolving serious infections and cytopenias.

This study found that mice with a mutant CDP/Cux protein lacking the homeodomain showed severely impaired growth, high postnatal mortality, and reduced fertility, highlighting CDP/Cux's role in developmental regulation.
