This study identified three novel genetic loci associated with PCOS and found similar genetic architecture across different diagnostic criteria, with evidence suggesting genetic links between PCOS and various metabolic and psychological traits.

In this review, the authors summarize classical and recent insights into the biology and treatment of hypertrophic scars and keloids, concluding that while understanding and strategies have advanced, effective prevention and treatments remain unsatisfactory.

This review discusses the role of the TOR pathway in aging and suggests that rapamycin could potentially target age-related diseases, but reports no new clinical results.

This study found that Wnt signaling in the hair follicle is crucial for coordinating the behavior of epithelial and melanocyte stem cells, which drives hair regeneration and melanocyte differentiation in mice.

This review discusses the hypothesis that polycystic ovary syndrome may originate in fetal life due to prenatal androgen exposure, but reports no new clinical results.

This study found that many effects previously thought to be caused by circadian rhythm disruption in Bmal1 knockout mice are actually due to BMAL1's properties unrelated to its clock function.

This study found that using curated biomedical databases as training examples for information extraction tasks in Genome-Wide Association Studies can outperform cost-insensitive methods, demonstrating their potential use without expert annotation.

Two main types of fibroblasts with unique functions and additional subtypes were identified in human skin.

This study found that removing PPARγ specifically from mouse adipose tissue led to severe fat loss, insulin resistance, diabetes, and associated metabolic abnormalities.

This study found that glycolytic metabolism and lactate production are crucial for hair follicle stem cell activation, and manipulating these processes can stimulate the hair cycle.

This article discusses the development of an evidence-based guideline for treating androgenetic alopecia and reports no new research results.

In a mouse model, this study demonstrated that a microneedle patch system using keratin and integrated with MSC-derived exosomes and UK5099 promoted hair regrowth more efficiently than traditional delivery methods.

This study found that polycomb-group-mediated repression plays a key role in regulating hair follicle stem cell states and lineage progression by distinct mechanisms in adult mouse skin.

In this study, androgen did not affect keratinocyte growth in coculture with androgenetic alopecia-derived dermal papilla cells, but did significantly suppress keratinocyte growth when androgen receptor was overexpressed in the papilla cells.

This study found that hMSC secretomes from umbilical cord Wharton's jelly had the most potent angiogenic effects, whereas those from adipose tissue demonstrated the weakest angiogenic potential.

This study identifies a bipotent stem cell in adult hair follicles that self-renews and contributes to dermal sheath and papilla cell populations, potentially aiding hair regrowth after injury, disease, or aging.

This article discusses advancements in understanding how skin stem cells and fibroblasts contribute to scar formation, highlighting current and potential therapies aimed at preventing or reducing scarring, yet notes that effective treatments without significant side effects are still lacking.

This study found that in a population of hair follicles, regenerative cycling stages are regulated by both intrinsic and extrinsic signals, with WNT/BMP signaling mediating interactions among follicles for adaptability.

This review summarizes the roles of bone morphogenetic proteins in the development and regulation of normal and diseased skin, but it does not provide new clinical results.

This study found that macrophages near hair follicles contribute to the activation of skin epithelial stem cells in mice, suggesting a novel role for macrophages in regulating hair growth.

This study found that squamous cell carcinomas from hair follicle stem cells are more prone to epithelial to mesenchymal transition and metastasis than those from interfollicular epidermis, due to distinct chromatin landscapes.

This study reports a less invasive method for detecting human clock gene expression using hair follicle cells, which accurately reflects individual behavioral rhythms and suggests a time lag issue for rotating shift workers.

This study found that specific ATP-competitive TOR inhibitors (asTORis) decrease root growth in Arabidopsis thaliana in a dose-dependent manner, similar to their effects on mammalian cells.

This study found that 'smart' peptide hydrogels improved wound healing in a rat model of partial thickness burns, achieving greater wound closure and faster debridement compared to a standard treatment.

This study found that trilostane was effective in resolving symptoms such as polyuria and polydipsia in many dogs with pituitary-dependent hyperadrenocorticism, with significant hormone level reductions observed.

This study observed that quiescent label-retaining cells in the intestine, identified by Paneth cell markers, can switch to a proliferative state and activate Bmi1 expression during tissue injury, contributing to tissue regeneration.

This review discusses the molecular mechanisms by which oncogenic viruses contribute to cancer development through manipulation of host cellular functions and highlights the need for further research into virus-associated cancers, reporting no new results.

This study found that dermal Shh signaling regulates specific dermal papilla signatures essential for maintaining hair follicle development, suggesting that the Shh-Noggin signaling loop is crucial for hair morphogenesis.

In this study, researchers used genetic data from over 52,000 men to identify over 250 genetic loci associated with severe hair loss and developed a predictive algorithm for determining hair loss risk.

In this study, human dermal fibroblasts were identified as natural host cells that support productive Merkel cell polyomavirus infection, and the MEK antagonist trametinib was introduced as an effective inhibitor to control the virus.
