This review discusses strategies for identifying and characterizing adult stem cells in mice and highlights their potential and limitations, but reports no new experimental results.

This study identified a domain on human chromosome 21q22.1 containing various high glycine-tyrosine and high sulfur keratin-associated protein genes, revealing their diverse expression in hair-forming cells.

This study found that methylprednisolone can block IgG-induced keratinocyte detachment in an animal model of pemphigus vulgaris, potentially by increasing the synthesis and modifying adhesion molecules.

Gene expression in wool follicles changes with growth cycles, offering insights into wool and human hair growth.

This study identified more than 100 genetic loci associated with hair color variation in Europeans, explaining a significant portion of the trait's heritability and advancing understanding of hair pigmentation.

This review discusses the similar immune pathways and genetic risk factors of vitiligo and alopecia areata but reports no new clinical findings, emphasizing the potential for shared treatment research.

This study introduces a method for long-term expansion of adult mouse epidermal stem cells in vitro using an organoid culture system that maintains the basal-apical organization.

This study found that rice genotypes exhibit significant variation in root hair properties under low phosphorus conditions, with genotype DJ123 showing particularly efficient root hair growth and phosphorus uptake.

This study in mice found that overexpressing Sonic Hedgehog in basal cells caused skin anomalies and a lack of certain hair fibers, underscoring its key role in hair follicle development.

Effective vaccines and treatments are crucial for long-term COVID-19 control.

This study observed that in vitro exposure to dihydrotestosterone worsened COVID-19 spike protein-induced endothelial injury, while spironolactone showed potential in reducing this effect, suggesting a rationale for further evaluation in treating COVID-19.

This study found associations between genetic predictors of increased testosterone and cardiovascular risk factors, but the implications for testosterone supplementation are unclear due to uncertainties in genetic variant functions.

This review discusses global variations in polycystic ovary syndrome prevalence and highlights the need for more comprehensive studies to understand its association with race, ethnicity, and diagnosis criteria; it reports no new results.

In this study, specific SNPs in the FST gene were significantly associated with various wool quality traits in Chinese Merino sheep, suggesting potential markers for breeding programs.

This study found that sheep possess a polymorphic KAP8-2 gene that shares high sequence identity with the KAP8-2 gene in goats and reindeer.

This retrospective cohort study found that patients using 5α-reductase inhibitors had reduced bladder cancer-related mortality compared to nonusers, with no significant effect on bladder cancer recurrence or upper tract urothelial carcinoma mortality.

The study observed that testosterone reduced knee range of motion in ovariectomized female rats, potentially by downregulating specific relaxin receptor isoforms, with its effects mediated via dihydro-testosterone.

This study identified a shared gene signature in scarring alopecia subtypes, with increased mast cell presence, suggesting similar treatment approaches may be effective across these hair loss disorders.

This review discusses methods for generating induced pluripotent stem cells and highlights their recent applications in studying and treating COVID-19, but it reports no new experimental results.

This protocol outlines a nationwide study to investigate the prevalence of metabolic and reproductive abnormalities, anxiety, and depression in Brazilian women with polycystic ovary syndrome, aiming to inform public health strategies.

In this study, researchers found that basal cell carcinomas with common Hedgehog signaling mutations may require additional mutations to hyperactivate downstream signaling and progress beyond dormancy.

In this study, the authors review how epigenetic regulation influences the role of iPSC-derived neural stem/progenitor cells in spinal cord injury therapy, highlighting challenges in the cells' generation, differentiation, and transplantation, and the effect of therapeutic tools on these processes.

This study found that in adolescent male rats, androgens enhance inhibitory avoidance memory, possibly by interacting with androgen receptors in the amygdala and hippocampus.

In this study, researchers found that the pCLCA2 protein is expressed in specific areas of pig skin, but its role in skin structure or function remains unclear.

This review explores how androgen administration might help alleviate inflammation and mitochondrial impairment in traumatic brain injury but reports no new experimental findings, calling attention to the need for further investigation.

This study observed hair-specific transcription of a reporter gene in transgenic mice, with increased expression after dexamethasone and ultraviolet B treatment.

In this study, researchers observed that male COVID-19 patients with more than 23 CAG repeats in the androgen receptor gene and lower testosterone levels experienced more severe disease outcomes.

This study suggests that Sox13, although dispensable for epidermal development, serves as a marker for early hair follicle development in Sox13-LacZ knock-in mice.

In this study, researchers observed that acute stress increased levels of the enzyme 5αR2 in the medial prefrontal cortex of male rats, affecting stress reactivity, but this effect was not seen in females.

This review highlights advancements in applying single-cell sequencing to cattle, sheep, and goats, noting its potential to elucidate cellular diversity and improve traits affecting livestock health and productivity, despite challenges in cell population annotation and spatial resolution in these species.
