This article reviews the use of hair cortisol concentration as a biomarker to assess long-term stress in both animals and humans, but it reports no new experimental results.

This study found that deleting the CD98hc protein in mouse skin impairs wound healing and homeostasis, resembling aging effects, due to disrupted integrin signaling pathways.

This study identified chemokine receptor ligands cxcl10 and cxcl11 as new hair-specific transcriptional targets of the Eda pathway, suggesting chemokine signaling plays a role in primary hair follicle patterning.

This review discusses the role of Hedgehog signaling in epidermal and hair follicle development and its involvement in basal cell carcinoma, without reporting new empirical findings.

This abstract discusses the dermatological symptoms associated with hepatitis C virus infections but reports no new research findings.

Mutations in the hHb6 gene cause the hair disorder monilethrix.

This review discusses the evaluation, clinical presentation, and cutaneous manifestations of congenital adrenal hyperplasia, focusing on differential diagnosis challenges with polycystic ovary syndrome, and reports no new clinical findings.

This study found that mutant cells in hair follicles can be tolerated or eliminated by surrounding normal tissue, suggesting the potential for wild-type cells to counteract oncogenic mutations.

Congenital Adrenal Hyperplasia is mainly caused by enzyme deficiencies, leading to varying symptoms like hormone imbalances and physical changes.

This study describes a mouse model for Marie Unna Hereditary Hypotrichosis, identifying mutations in the hairless gene that result in sparse or absent hair and cyst-like hair follicles.

This review discusses genetic mutations associated with Hutchinson-Gilford progeria syndrome and reports no clinical results; the authors emphasize the importance of cardiovascular monitoring in management.

In this study, researchers created a mutant mouse lacking the first cut repeat in the Cux/CDP protein, resulting in curly vibrissae and wavy hair, supporting the role of Cux/CDP's DNA binding domains in gene regulation during development.

In this study, researchers identified a novel and two previously reported pathogenic mutations in the HR gene associated with atrichia with papular lesions in five Pakistani families.

This study identified a novel CDH3 mutation associated with sparse hair and pigmentary macular changes in two siblings with hypotrichosis but no visual symptoms.

This study explored the effects of a common Hutchinson-Gilford progeria syndrome mutation in an inducible mouse model, revealing skin abnormalities similar to those in affected patients.

In this study, researchers found that overexpression of the Hedgehog signaling effector Gli2 in mice led to odontogenic keratocysts development, implicating GLI transcription factors in human keratocyst pathogenesis.

In this study, mice engineered to express human EGFR showed tissue-specific growth defects and neurodegeneration rescue, but developed severe heart issues and accelerated bone cell differentiation.

This study identified a human sequence likely coding for a new ultra-high sulphur protein, which may aid in understanding hair differentiation and the molecular basis of human trichothiodystrophy.

This study suggests that Houttuynia cordata extract may promote hair growth by stimulating dermal papilla cell proliferation and extending the anagen phase through enhanced energy metabolism and gene expression changes.

In this study, injecting chimeric RNA–DNA oligonucleotides into mice skin caused a temporary mutation in keratin 17, altering hair morphology, but the mutation was transient due to genetic compensation or cell replacement.

This study found that DHHC13 is crucial for hair anchoring and skin barrier function, with its deficiency in Zdhhc13(skc4) mice leading to cyclic alopecia and skin abnormalities due to cornifelin deficiencies.

The researchers found that HOXC13 regulates different keratin proteins in a mixed manner, with certain SNPs impeding this regulation, while also demonstrating negative-feedback by HOXC13 and positive regulation by LEF1 and melatonin on the HOXC13 promoter.

This review covers the pathophysiology, diagnosis, and treatment of congenital adrenal hyperplasia due to 21-hydroxylase deficiency and reports no new findings.

This study found that a newly identified mutation in the hairless gene in mice led to decreased Hr mRNA levels and changes in gene expression related to hair follicle development.

In this study, Huoxue Bushen Mixture was associated with increased blood vessel formation and VEGF expression in mice hair follicles, suggesting it may enhance hair growth.

This research reports a new autosomal recessive mutation in mice, 'lanceolate hair', causing generalized alopecia and hair shaft abnormalities, which may serve as a model for Netherton's syndrome in humans.

This study suggests that impaired Nrf2 signaling and its relationship with keratin 16 may contribute to follicular hyperkeratinization and occlusion in hidradenitis suppurativa, opening new therapeutic avenues.
