This study described the clinical and genetic features of two Iranian siblings with hereditary vitamin D resistant rickets, identifying a specific VDR gene mutation contributing to their symptoms.

TRH in hair follicles can influence hair color by increasing melanin.

This study demonstrates that miniaturized hair follicles in female pattern hair loss overexpress nuclear aryl hydrocarbon receptors, suggesting a potential role for environmental pollutants in this condition.

This study found that a novel R343H mutation in the vitamin D receptor gene impairs its transcription activity, contributing to hereditary vitamin D-resistant rickets and alopecia in the affected family.

This study identified a monoclonal antibody, HKN-2, that recognizes specific cells in human skin and may indicate a common antigenic determinant between hair and other skin epithelial tissues.

This study generated a transcriptomic map of human hair follicles, identifying compartment-specific gene expression profiles that can aid in developing targeted therapies for hair follicle disorders.

In this study, researchers identified two distinct homozygous mutations in the KRT85 gene among consanguineous Pakistani families with pure hair and nail ectodermal dysplasia, highlighting variations in severity and potential impacts on the K85 protein function.

This study observed that female nurses experienced higher hair cortisol concentrations, indicating increased stress, during periods of the COVID-19 pandemic compared to the summer release period.

This study suggests that human scalp hair follicles express erythropoietin and its receptor, up-regulating receptor expression under hypoxic conditions, and may mimic another hypothalamus–pituitary axis equivalent involving the TRH-TSH system.

This study found that mutations in the hairless gene in mice disrupt hair follicle integrity during catagen, leading to baldness due to disintegrating epithelial structures and loss of normal dermal papilla.

This study reports that a new DART-HRMS method can effectively analyze intact hair for drug use timelines, with cocaine detection aligning with forensic standards and identifying multiple drugs from high-resolution data.

This study found that the long non-coding RNA lnc056 promotes the proliferation of hair follicle stem cells by upregulating TRIP6 expression through interaction with the transcription factor HNRNPUL1, suggesting a potential target for hair loss treatment.

This study characterized a new human keratin, hK6irs1, specifically found in the inner root sheath of hair follicles, which suggests its role in the structural integrity and guidance of growing hair shafts.

This study observed that putrescine and HR form a negative feedback mechanism affecting hair cycling, indicating a significant connection between HR, polyamines, and hair growth regulation.

This review discusses multiple physiological roles of parathyroid hormone-related protein, such as cartilage mineralization and hair follicle regulation, and reports no new experimental results.

This study found that most pathogenic HR mutants associated with atrichia with papular lesions had abolished corepressor activity due to defective interactions with histone deacetylases.

This study demonstrates that the trichohyalin gene is located at chromosomal region 1q21, where several other genes related to epidermal differentiation also map.

In this study, a Chinese Han family with hereditary vitamin D-resistant rickets was found to have a homozygous missense mutation in the VDR gene, and the affected individual uniquely responded well to treatment with oral calcium and low-dose calcitriol.

This study found that human placenta hydrolysate effectively inhibited atopic dermatitis development in stimulated human cells and a mouse model, suggesting its potential as a therapeutic agent for related skin diseases.

This piece marks the tenth anniversary of the American Board of Hair Restoration Surgery and highlights the addition of 14 new diplomates from diverse countries, while reporting no new clinical findings.

This article summarizes a meeting of the American Board of Hair Restoration Surgery's Board of Directors to discuss future plans, but does not report new experimental results.

This study found that HtrA2 inactivation in mnd2 mice is associated with delayed hair cycle phases and growth retardation of adipocytes, suggesting HtrA2's role in regulating adipogenesis-related hair growth.

This study found that both a high dose of CPA and GnRHa are effective for treating hirsutism in hyperandrogenic women, but GnRHa with add-back therapy may lead to a longer remission period.

This study identified the c.1204G to A (p.E402K) mutation in the hHB6 gene as a cause of monilethrix in a Chinese family, highlighting the gene's role in the condition.

This study reports the first case of atrichia with papular lesions in a Taiwanese family without a detectable mutation in the HR gene.

This review discusses the role of corticotropin-releasing hormone in human skin, focusing on its regulation, receptors, and functions, and highlights parallels with the hypothalamo-pituitary-adrenal axis; it reports no new research findings.

In this case study, a girl with hereditary vitamin D resistant rickets had a novel mutation in the VDR gene that affected hair cycling without causing total alopecia, suggesting ligand-independent VDR function in hair cycling.

This study identified a distinct gene near the hairless locus on chromosome 8p that is responsible for hereditary Marie Unna type hypotrichosis in a German family.
