This study found that acute UVB exposure in mice increases the synthesis of retinoic acid in the epidermis, which is necessary for normal repair from UVB light.

This study found that human hair shafts are a rich and stable source of RNA, which can be extracted for analysis and used in personalized medicine and diagnostic applications.

This article discusses how drug molecules integrate into hair fibers, focusing on biological transport mechanisms and physicochemical factors, but reports no new experimental findings.

This study analyzed gene expression in Pashmina goats and identified key biological processes and molecular functions involved in long-fibre production, suggesting potential pathways for enhancing this trait in other goat breeds.

In this in silico study, researchers found that the hair follicle's contribution to dermal permeability of small molecules varies with the lipophilic and hydrophilic properties of substances, highlighting the need for careful characterization of substances filling the follicular route when interpreting experimental permeability data.

This study describes a family with X-linked gynecomastia and undervirilization in men, finding a subtle androgen receptor abnormality that may not always lead to infertility despite androgen resistance.

This study reports that the autotaxin–LPA–LPA3 signaling pathway at the embryo-epithelial boundary plays a critical role in decidualization by up-regulating HB-EGF and COX-2 in the uterine epithelium.

This study found a previously unreported ST14 gene mutation in a patient with ichthyosis-hypotrichosis syndrome, highlighting novel skin and hair characteristics and emphasizing the critical role of the Asp482 amino acid in matriptase activation.

This study found that the moisture sorption and desorption process can differentiate between cosmetic treatments of hair and provide insights into hair fibre structure changes, with bleaching causing greater symmetry breaking than perming.

This study describes a family where a TP63 mutation was linked with prominent alopecia and mild ectodermal dysplasia features.

This study identified two types of hard alpha-keratin filament assemblies in developing human hair follicles, which may help investigate the structural framework of mammalian keratin appendages.

This study identified several DPC-specific proteins, including ITGB1, IGFBP3, and THBS1, as potential biomarkers for hair growth modulation through proteomic and network analysis.

This study found that vitamin C increased the survival, proliferation, and hair-regenerative potential of adipose-derived stem cells through the MAPK pathway and enhanced hair growth in mice.

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.

This study synthesizes knowledge of how dendritic cell signals, epithelial integrins, and fibroblast activity converge on TGF-β1 to maintain or disrupt skin healing, contrasting normal and fibrotic scar formation and suggesting possible integrin and immune-targeted treatments for skin fibrosis.

This study found that zebrafish and stickleback fish use similar genetic programs for tooth regeneration, despite differences in their dental structures.

This study found that an 8-week supplementation with specific probiotic strains improved hormonal markers and oxidative stress while decreasing inflammation in women with PCOS, although clinical symptoms like acne and hirsutism showed no significant improvement compared to the placebo group.

This study found that tribuloside, a flavonoid from Tribulus terrestris L., enhances melanin production in human melanocytes, zebrafish, and human skin samples without causing toxicity, potentially through inhibiting PDE to increase cAMP levels and promote the melanin biosynthesis pathway.

This study found that citron seed oil promotes hair regrowth in a C57BL/6 mouse model by enhancing the transition to the growth phase, increasing hair follicle features and skin thickness, and inducing specific protein expressions that support hair regeneration.

This study indicates that MAGE-11 modulates androgen receptor transcriptional activity through F-box interactions, independent of the activation function 2 pathway, revealing a novel mechanism for androgen receptor regulation.

This study found that in mice, inactivating beta-catenin in the dermal papilla reduces hair follicle progenitor proliferation and disrupts the hair cycle.

This review discusses the effects of IGF-1 on hair follicle cell proliferation and differentiation, highlighting its roles in paracrine signaling, apoptosis prevention, and hair growth, but reports no new clinical results.

This study found that women with symptoms of oligomenorrhoea and/or hirsutism are more likely to have polycystic ovaries and less favorable biochemical and clinical markers compared to asymptomatic women.

This review explores the potential (neuro-)endocrine influences on hair follicle epithelial stem cell biology and emphasizes the need for more systematic research, but it provides no new empirical results.

This study found that RXR agonists stimulated human hair follicle growth and survival in vitro, suggesting potential for promoting hair growth in humans.

This study found that the HS III element in the K14 gene's regulatory sequence promotes gene expression in inner root sheath keratinocytes, highlighting cooperative interactions in keratinocyte-specific gene regulation.

This review discusses potential new drug treatment strategies for alopecia areata based on genome-wide association study findings, but it reports no new clinical results.

This study found that human umbilical cord blood mesenchymal stem cells promoted hair growth by advancing anagen onset and increasing hair follicle regeneration in an in vivo model.

This study found that telogen, a resting phase of the hair follicle cycle, is characterized by dynamic gene expression, including enhanced cholesterol metabolism and immune signaling, suggesting it is an active regulatory phase despite its quiescent appearance.

This study found that certain T cell-associated genes were upregulated in dogs with Vogt-Koyanagi-Harada syndrome and vitiligo, suggesting a shared immunopathogenesis with humans.
