PCOS may have evolved as an advantage in past environments with food scarcity.

This study found that monocytes/macrophages with a pro-inflammatory M1-like phenotype may play a crucial role in the pathogenesis of hidradenitis suppurativa, suggesting potential therapeutic targets.

In this study, the misshaped and hairy ear phenotype in mutant mice was linked to mis-expression of certain Hoxc genes due to a chromosomal inversion.

This study demonstrated that genetic markers can predict human ear morphology with moderate to good accuracy, potentially aiding forensic identification in crime scene investigations where traditional DNA matches are unavailable.

This discussion highlights the potential of next-generation sequencing in forensic science for predicting phenotypic traits from DNA samples, but reports no new clinical results and underscores ongoing ethical and legal challenges.

Androgens, like DHT, affect hair growth and treatments like finasteride may help.

This study found evidence for a genetic basis of polycystic ovary syndrome, indicating an autosomal dominant pattern of inheritance among first-degree relatives.

This study identified a high proportion of dual TCR Treg cells in both lymphoid and non-lymphoid tissues of mice, revealing their tissue specificity, TCR repertoire characteristics, and functional phenotypes.

This study concluded that removing alopecia and mucous membrane components from the CLASI-A score limits the ability to capture crucial clinical information about cutaneous lupus erythematosus activity, recommending their retention.

This study found that the loss of Msx2 in knockout mice led to phenotypes similar to Peters anomaly and microphthalmia, suggesting that MSX2 plays a critical role in anterior segment development of the eye.

This case report identifies a novel maternally inherited MBTPS2 variant associated with an expanded phenotypic spectrum of BRESHECK syndrome, including cytopenias, bone marrow fibrosis, and chronic diarrhea.

This article discusses various mechanisms for promoting hair growth in pattern hair loss and highlights the challenge of balancing short-term measurable results in trials with the need for long-term efficacy data.

This study found that zebrafish and sticklebacks, despite differences in their tooth regeneration structures, share a similar genetic program during tooth regeneration, suggesting a conserved "successional dental epithelium" in vertebrates.

In this study, researchers observed significant differences in hair follicle microbiome diversity and microbial composition between hair loss and healthy groups, uncovering specific patterns and functional changes associated with female pattern hair loss, which may aid future targeted approaches for androgenetic alopecia.

In this study, researchers observed that Thunbergia grandiflora and Russelia equisetiformis exhibited mutual aid by altering their phenotypic characteristics to facilitate intertwining, suggesting a form of solidarity without apparent external threats.

This study found that LepRb neurons in the brain are important targets for androgen action and influence sex-specific differences in reproductive and metabolic regulation, implicating them in conditions such as polycystic ovary syndrome.

This study found that Swiss cattle exhibiting rat-tail syndrome are heterozygous for genetic variants linked to pigmentation and color dilution, likely due to Holstein introgression in the Simmental breed.

This study found that overexpression of the enzyme spermidine/spermine N1-acetyltransferase in mice was associated with increased fat oxidation and a leaner phenotype, while knock-out mice exhibited increased fat accumulation.

This review discusses the unique features of fetal wound healing that may enable scarless repair and reports no new experimental findings.

In this study, researchers used an evolutionary-rate-based method to identify genetic elements associated with reduced hair in mammals, finding a dichotomy between accelerated coding sequences and noncoding regulatory elements influencing hair growth.

This study identified a 69 bp deletion in the KRT75 gene as the cause of the frizzle feather trait in chickens, affecting feather curling.

In this study, a methanol extract of Eclipta alba was found to have dose-dependent hair growth-promoting activity in C57BL6 mice.

This study reports that a new nude allele, nu(StL), encodes a truncated Whn transcription factor affecting T-cell development and keratin gene expression, with notable differences from the original Whn(nu) mutation.

This article reviews the effects of 5 alpha-reductase inhibitors for treating conditions like male pattern baldness and benign prostatic hyperplasia, noting significant DHT reduction but reports no new clinical results.

This study found that administering spermidine to aged mice for six months significantly reduced various age-related conditions, including brain, heart, kidney, liver issues, and hair loss, possibly due to decreased telomere attrition.

This study found no significant association between androgenetic alopecia and metabolic syndrome, though systolic blood pressure was higher in the alopecia group compared to controls.

In this study, researchers found that single SNPs have a small genetic effect on phenotypes in Inner Mongolia cashmere goats, and constructing haplotypes from associated SNPs may uncover complex variations in cashmere traits, aiding genomics and breeding efforts.

This study found a significant association between the IRS-2 gene variant and an increased risk of PCOS, especially in non-obese women in the Chinese population from Taiwan.

This study found that the transcription factor CAP1 negatively regulates KRT83 expression in Tan sheep, possibly influencing their curly hair phenotype.

This study found that genetic variation in the KRTAP21-2 gene among crossbred Merino lambs was associated with differences in wool traits, particularly mean staple length.
