This study identified novel compound heterozygous mutations in the DSG4 gene in a Japanese patient with congenital hypotrichosis, suggesting overlap between localized autosomal recessive hypotrichosis and monilethrix.

This study discovered nine human type I hair keratin genes, including a transcribed pseudogene, in a 190 kbp genomic region, revealing three gene subclusters based on sequence homologies.

This study found that LGR5 is uniquely expressed in human corneal endothelial cells and maintains endothelial cell phenotypes while inhibiting mesenchymal transformation through the Wnt pathway.

This study found that human hair follicle-derived mesenchymal stem cells can differentiate into myogenic, osteogenic, adipogenic, and chondrogenic lineages, although this potential decreases over time and varies by lineage.

This study identified that a deficiency in the palmitoyl transferase enzyme, due to a mutation in the Zdhhc13 gene, led to severe physiological abnormalities in mice, including skin, bone, and systemic amyloid issues.

In this study, researchers found that disrupting the PRL gene in mice led to earlier hair molting, especially in females, suggesting that PRL inhibits murine hair cycle events.

This study found that dysregulation of the folliculin-p0071 interaction may lead to changes in cell adhesion and signaling, contributing to conditions like emphysema and renal cell carcinoma.

This study found that thyrotropin-releasing hormone (TRH) acts as a potent stimulator of hair growth in human scalp hair follicles, promoting elongation and prolonging the anagen phase.

This study found that the co-activator CBP enhances the agonistic action of hydroxyflutamide on androgen receptors, suggesting a mechanism for therapy resistance in prostate cancer.

This study observed that human hair follicles were able to regenerate fiber-forming structures after the bulb was amputated and transplanted onto athymic mice, suggesting a general regenerative capacity.

This study found that human hair follicles express erythropoietin and its receptor, suggesting these follicles may use erythropoietin signaling to modulate apoptosis under stress conditions like hypoxia and chemotherapy.

This study found that p53 plays a crucial role in regulating apoptosis during hair follicle regression (catagen) in mice, and its absence leads to delayed progression and altered expression of apoptosis-related markers.

This study reports that plasma rich in growth factors appeared to improve hair follicle regeneration and patient satisfaction in individuals with androgenetic alopecia, though further trials are needed.

This review discusses the role of keratins in maintaining epidermal structure and function and reports no new results; the authors emphasize the lack of rational therapies for skin disorders linked to keratin mutations.

This study found that securinine and ajmaline significantly inhibited hepatocellular carcinoma cell viability and induced apoptosis, with securinine showing lower toxicity to normal liver cells.

This review discusses the advancements and challenges in developing in vitro human skin models incorporating components like vasculature for drug testing and disease research, but reports no new clinical results.

This study found that CD45RO+ cells, a subtype of T lymphocytes, were notably reduced in the ovarian follicles of women with PCOS, which may contribute to the condition's pathogenesis.

This study found that ectopic expression of Whn in transgenic mice caused impaired differentiation in epidermis and hair follicles, with hair growth defects and severe urinary tract issues leading to hydronephrosis.

This study found that untreated men with coeliac disease exhibited androgen resistance, potentially linked to sexual dysfunction, which improved as intestinal health improved, a pattern not observed in other chronic illnesses.

This study demonstrates that inhibiting SFRP1 with the antagonist WAY-316606 enhances hair growth in human scalp hair follicles ex vivo by facilitating Wnt signalling.

This study found that in vivo, a novel microneedle system for valproic acid delivery may improve hair regrowth efficacy by upregulating hair follicle development pathways more effectively than topical application.

This study found that composite skin constructs containing dermal papilla cells promoted better skin healing and hair regeneration in nude mice, highlighting their role in tissue-engineered skin for severe injuries.

This study reported that a three-dimensional hydrogel culture system supports the growth and maintenance of distinct dermal papilla cell types, crucial for skin reconstitution assays in neonatal mice.

This study found that nonionic liposomes were the most effective vehicle for delivering reporter genes into the skin of rat pups, compared to other liposome and nonliposome formulations.

This study found that beta-caryophyllene enhanced re-epithelialization in cutaneous wounds of female mice, suggesting its potential for improving wound healing through multiple pathways.

This study demonstrated that a c-Kit-CreER-driven mouse model confirms melanocyte stem cells as a genuine source of melanoma, paralleling human melanoma in heterogeneity and gene signatures.

This study found that endocrine therapy for breast cancer is associated with a pattern of hair loss similar to androgenetic alopecia, negatively impacting quality of life despite mild severity.

This study found that β-catenin signaling increases in newly born glial cells in the cortex after traumatic brain injury in mice, suggesting potential targets for enhancing recovery through the Wnt/β-catenin pathway.

This study found that overexpression of the mineralocorticoid receptor in a mouse model led to premature epidermal barrier development, keratinocyte apoptosis, and postnatal alopecia, indicating new roles for MR signaling in skin physiology.

This review explores the mechanisms of hair cell death due to factors like noise, ototoxic drugs, and aging and reports no conclusive clinical results; ongoing research may eventually enable preventive treatments for hearing loss.
