This review discusses the development and role of corneodesmosin in skin and hair follicle integrity, highlighting findings from mouse models and its connection to genetic diseases, with no new experimental results included.

This review discusses potential mechanisms contributing to higher COVID-19 mortality among men, particularly the roles of smoking, genetic factors, and reproductive hormones, without presenting new clinical findings.

This article reviews genetic and phenotypic aspects of androgen insensitivity syndromes, emphasizing the diversity of mutations that complicates molecular screening and the importance of genotype-phenotype correlations.

This review discusses androgenetic alopecia and alopecia areata through a systems biology lens, emphasizing the role of multi-omics data integration to explore molecular mechanisms and potential therapeutic strategies, but offers no new clinical results.

This study suggests that topical procyanidin B-2 is safe for use as a hair growth agent, as it showed no mutagenic effects or significant irritation in a series of toxicological tests.

This article reviews the genetic and potential environmental factors in alopecia areata's pathogenesis and suggests a polygenic model but reports no new clinical findings.

The Dfl mutation in mice causes poor sebaceous gland function and complete hair loss.

This research suggests that targeting the HIF-1α pathway via PHD inhibitors may enable regeneration similar to amphibians in mammals, potentially fast-tracking regenerative therapies from mice to humans.

This article discusses the discovery of the first known menstruating rodent, the spiny mouse, and proposes that a significant increase in progesterone during the luteal phase is a unique feature of menstruating species, but reports no new experimental results.

This study found that the gene SRD5A1, associated with methylation changes due to early-life environment, may play a role in altering reproductive phenotypes in women by delaying pubertal onset and decreasing ovarian reserve.

This review discusses recent findings on hair follicle morphogenesis and regeneration, focusing on molecular signals and stem cells, and suggests that understanding these processes may aid in developing new strategies for wound healing.

This study found that a newly identified gene, mK17n, may explain the lack of nail issues in mK17 null mice by compensating for mK17's function in the nail bed.

This study identified a 195 bp duplication in crested chickens that causes large crest feathers and can be associated with cerebral hernia in some breeds, but not all.

This study found an association between 'short' CAG repeats in the androgen receptor gene and increased non-random X chromosome inactivation in women with androgenic alopecia.

This review discusses sex differences in immune responses and highlights mechanisms involving sex hormones, X-linked genes, and X-Chromosome Inactivation, but reports no new clinical findings.

This review explores the structural and functional sex differences in mammals beyond reproductive organs, highlighting variations in life expectancy, organ size, metabolism, and immune function, but it reports no new results.

This study reports that X chromosomes often show greater differentiation between human populations than autosomes, likely due to a mix of demography and selection pressures.

Alopecia areata is complex, with genetic and immune factors, and animal models are key for future treatment research.

This study developed the mTurquoise2-Col4a1 mouse model and used fluorescent tagging of collagen IV to offer new insights into basement membrane dynamics during hair follicle budding, revealing that basement membranes are flexible and stable structures in developing skin tissue.

This study found that administering the gut bacterium Thauera sp. strain GDN1 to mice significantly reduced their serum androgen levels, indicating gut bacteria may influence androgen metabolism.

A gene mutation causes a rare hereditary hair loss, offering potential for new treatments.

This study identified a missense mutation in the human hairless gene associated with a rare form of recessively inherited alopecia universalis, pinpointed on chromosome 8p12.

This study found that purified apple juice containing procyanidin B-2 promoted hair growth in both mouse models and human clinical trials for male pattern baldness.

This study identified and characterized a gene called 4C32, which is expressed in the periderm of embryonic mouse skin and has a structure similar to keratin-associated proteins.

This study identified a novel locus for hereditary hypotrichosis simplex on chromosome 13q12.12~12.3 in a four-generation Chinese family.

This study found that recombinant hepatitis B vaccine may increase the risk of alopecia areata onset in older predisposed mice but larger trials suggest this effect might lie within normal variation.

This review discusses genetically-engineered mouse models for studying melanocytes and reports no new experimental findings; it emphasizes their potential to address unanswered questions in melanoma biology.

This study observed that numerical chromosomal aberrations were more common in men with severe male factor infertility and azoospermia compared to those with other sperm quality issues, while chromosomal translocations were significantly associated with oligoasthenozoospermia, highlighting important genetic counseling considerations.

This study found that administering an adenovirus vector to increase Sonic hedgehog gene expression in mouse skin accelerated the transition of hair follicles into the growth phase, promoting hair growth.

This review discusses recent molecular biology advances in the human phenol sulfotransferase gene family and reports no new results; the authors highlight its relevance for studies of endogenous and xenobiotic metabolism.
