In a controlled study, researchers observed that lambs exposed to colder temperatures had increased wool growth, thicker skin, altered physiological traits, and activated specific molecular pathways, highlighting potential targets for enhancing cold tolerance, welfare, and productivity in sheep breeds.

In this animal study, researchers found that local administration of mesenchymal stem cell therapy improved hair regrowth and reduced local inflammatory cytokines in mice with Alopecia Areata, although systemic cytokine levels were unchanged.

This report describes a novel mutation in the CDH3 gene in an 11-year-old Iranian boy with hypotrichosis and juvenile macular dystrophy, indicating a new genetic variant associated with the disorder.

This study found that melatonin treatment increased epidermal thickness, subcutaneous fat, and dermal-related factors in postmenopausal rats, suggesting benefits for skin structure after menopause.

This review discusses the multifaceted actions of metformin in polycystic ovary syndrome and reports no new clinical results; the authors emphasize metformin's potential benefits in both cardiometabolic and reproductive aspects of PCOS.

In this study, molecular dynamics simulations indicated that the Glu413Lys mutation in human hair keratin significantly affects the stability of coiled coil structures, whereas Glu413Asp showed no impact on stability.

In this study, researchers identified specific long non-coding RNAs involved in feather development that do not follow traditional genetic inheritance patterns in chickens.

In this study, rice bran mineral extract increased expression of anagen-related proteins and decreased inflammatory markers in human dermal papilla cells, suggesting potential for hair growth enhancement and prevention of hair loss.

This study used transcriptome analysis to explore the genetic mechanisms behind the development and seasonal variation of nuptial pads in R. chensinensis, identifying key genes and processes that suggest the pads' development involves complex regulatory pathways, particularly those related to cell cycle and hormone synthesis.

In this research, sequencing the chloroplast genomes of 10 Sansevieria trifasciata cultivars allowed the identification of a trnT-psbD deletion marker capable of distinguishing closely related species, and highlighted evolutionary links with Dracaena, contributing molecular tools for taxonomy and phylogenetic studies in Asparagaceae.

Bimekizumab quickly improves psoriasis symptoms and skin at the molecular level.

This case report describes a novel mutation in the CDH3 gene in an 11-year-old Iranian boy with sparse scalp hair and macular dystrophy, leading to altered P-cadherin synthesis.

This study found that shampoo and conditioner do not alter hair's molecular structure, while perming treatments significantly affect keratin and intermediate filament structures due to bond alterations.

This review covers the structure, development, cycle, and molecular regulation of hair follicles but does not report new results, aiming to offer insights for addressing hair follicle-related diseases.

In this review, the authors emphasize that phenotypic heterogeneity in genetic systems and human diseases is influenced by stochastic fluctuation and network topology, proposing that ultrasensitivity and threshold effects explain this variability, which may inform strategies for preventing and treating genetic diseases.

This study introduced and validated a reliable and reproducible metal-free mouse model for ACLR surgery, providing a new tool to investigate the molecular mechanisms of graft-tunnel healing.

This study found that virgin coconut oil improved skin inflammation and symptoms of seborrheic dermatitis in rats, particularly at a dose of 10 mg/kg, by reversing alterations in antioxidant and inflammatory markers.

This study used single-cell transcriptomic analysis to identify a specific cell population in acne patients' non-lesional skin, providing evidence for the comedone switch hypothesis by suggesting a shift towards infundibular differentiation at the expense of sebaceous gland maintenance.

This study investigated age-related changes in female scalp dermal fibroblasts, finding alterations in gene and protein expressions associated with fibrosis and senescence, which could potentially affect hair follicle health and contribute to aging-related hair changes.

This article explores the complexity and significance of the hair follicle, emphasizing new insights into its biological roles and the involvement of p53 in follicular regression.
