This study found that among women with polycystic ovary syndrome, insulin resistance was more strongly associated with cardio-metabolic abnormalities than β-cell dysfunction, and they showed different correlations with obesity.

This study found that testosterone enhances insulin secretion in human pancreatic islets by being converted into DHT and E2, processes that are necessary for this effect.

This article reviews the potential mechanisms underlying polycystic ovary syndrome, emphasizing insulin resistance and hormone dysregulation, and reports no new research findings.

This study found that collagen VI is crucial for peripheral nerve function and regeneration, and its absence promotes abnormal hair regrowth after skin wounding in mice, revealing potential therapeutic targets for nerve injuries and hair loss.

This review discusses mechanisms of wound healing impairment in leptin-deficient murine models used for diabetic research, and reports no new clinical results; the authors emphasize the need for further study.

This review discusses the impaired functionality of regulatory T cells in the pancreas during the development of Type 1 diabetes, highlighting their role in disease pathogenesis, potential of Treg-based therapies, and challenges in clinical applications.

This study found that telomere shortening disrupts BMP/pSmad/P63 signaling, leading to skin atrophy via Follistatin up-regulation, and suggests potential therapeutic targets.

This study found that H-Ras activation in aged mouse skin leads to increased dysplasia and progression to in situ squamous cell carcinoma, highlighting an age-linked connection between immune changes, senescence, and cancer risk.

This study explored the complex roles of niche cells in regulating hair follicle stem cells, identifying specific cell functions such as signaling, sensing, and relaying messages, which could provide insights into treating hair loss conditions like androgenetic alopecia and alopecia areata.

In this study, researchers observed that the absence of the vitamin D receptor or its ligand-activated transcription in mice did not affect glucose homeostasis or gene expression in islets.

This review discusses advances in understanding mammalian stem cell niches, particularly in bone marrow, tooth, and hair follicle, and highlights the potential for developing therapies targeting these niches for tissue repair.

This paper reviews the use of interferons, particularly alfa interferon, in treating cutaneous T-cell lymphoma, noting its substantial efficacy both alone and in combination therapies with predictable, generally well-tolerated side effects.

This chapter discusses the skin stem cell niche as a complex ecosystem and highlights the diverse components and interactions that influence stem cell function, but it reports no new experimental results.

This study investigated single-cell changes in photoaged skin, revealing distinct cell clusters and increased activity in PD-L1 and PD-1 pathways in sun-exposed areas, enhancing understanding of UVA-induced skin damage and potential prevention targets for photoaging and UV-induced skin cancers.

In this study, Agaricus bisporus derived β-Glucan particles demonstrated antimicrobial, antioxidant, and anticancer effects against cervical cancer HeLa cells, suggesting potential as a therapeutic option.

This case report describes common thyroid disorders in a β-thalassemia patient with frequent blood transfusions, emphasizing the need for monitoring thyroid function in such patients.

This study found that overexpressing Rps14 in supporting cells promoted hair cell regeneration in the organ of Corti by facilitating cell proliferation and differentiation.

This forum article in BMC Biology discusses evolving views on the concept of the stem cell niche, highlighting varied mechanisms and the need for better understanding of the niche's roles and functions.

This study found that upcycled postbiotic cell-free supernatants from Limosilactobacillus fermentum MG901 and MG4237 protected human dermal papilla cells from oxidative stress, enhancing wound-healing capacity and mitochondrial function, suggesting potential as a sustainable cosmetic ingredient for hair loss alleviation.

p14ARF and p16Ink4a cause hair follicle stem cell aging and dysfunction.

This study by Dr. Manka and colleagues reported that thyroid hormones play a significant role in regulating hepatic stellate cells, influencing liver fibrosis progression via TGFβ signaling.

This review discusses genetic and epigenetic studies of PCOS, highlighting Genome-Wide Association Studies that found genetic variants related to gonadotrophin secretion influencing PCOS susceptibility, but it reports no new findings.

This study observed that Endoglin is crucial for maintaining correct hair follicle cycling and stimulating hair follicle stem cell niches through feedback interactions involving Wnt/β-catenin and Bmp/Smad signaling pathways in a mouse model.

Dermal exosomes with miR-218-5p boost hair growth by controlling β-catenin signaling.

This study found that resveratrol and fisetin promoted hair growth in mice by inducing telomerase reverse transcriptase expression, which activates hair follicle stem cells and transitions follicles from a resting to a growth phase.

This review discusses the mechanisms of skin barrier impairment in acne vulgaris and suggests strategies for its repair but reports no new clinical results.

This study found that vitamin A significantly enhanced the proliferation and inhibited apoptosis of rabbit dermal papilla cells under heat stress, likely by modulating miR-195/IGF1 and Wnt10b/β-catenin signaling pathways.

This study discusses how redox imbalance, specifically through reduced Insulin-like Growth Factor-1 mediated by the transcription factor JunB and sphingolipid metabolism changes, contributes to skin aging by depleting stem cell pools and altering the extracellular matrix, ultimately impacting skin integrity and function.

This review discusses the pathogenesis and challenges in treating primary cicatricial alopecia, highlighting the need to understand immune protection collapse in hair follicle stem cells; it reports no new clinical results.
