In this study, researchers found that the female plumage color variations in the common cuckoo are linked to the female-restricted genome and suggest this pattern is maintained by balancing selection, sharing ancestry with the oriental cuckoo.

This review found that while forensic DNA phenotyping and health applications for pigmentation genetics show potential, factors like phenotype definition and population diversity present challenges to accurate genotype-to-appearance predictions.

In this study, genetic factors associated with hirsutism were identified, suggesting that both androgen-dependent and independent mechanisms may contribute to excessive hair growth in women.

In this study, researchers did not find any genome-wide significant genetic signals linked to comorbid chronic inflammatory disorders in patients with alopecia areata, but exploratory analysis suggested potential associations worth further study.

In this study, researchers observed that chronic stress affected wild-derived house mice differently by sex, with females showing less weight gain and distinct behavioral changes, while males exhibited higher hair corticosterone levels, suggesting divergent coping strategies and implications for sex-specific stress assessment protocols.

This study found that acute stress can cause rapid hair loss by triggering necrosis in hair follicle cells and initiating autoimmunity, revealing a mechanism where stress-induced nerve activity leads to tissue damage and immune system activation.

In this study, chronic unpredictable stress affected male and female wild-derived house mice differently; stressed females gained less weight, had long grooming times, and lower immobility in tests, while stressed males showed increased hair corticosterone levels and shorter immobility times.

This review explores the mechanisms, current products, challenges, and innovative approaches related to cosmetics for hair loss prevention and growth promotion, emphasizing the need for multidisciplinary cooperation to enhance product development and market success.

This study reports that SARS-CoV-2 infection, COVID-19 vaccination, and off-label dupilumab treatment may exacerbate psoriasis, with overlapping inflammatory pathways involving cytokines like IL-17 and TNF-α. Histopathological similarities between psoriasis flares and COVID-19 skin manifestations were noted, suggesting a potential connection requiring further research.

This study found that integrating breed-specific BOA and SNP-based models helps reveal the genetic factors involved in thermotolerance traits in beef cattle, enhancing insights into thermoregulation and potentially improving cattle's heat resilience.

This review highlights the potential for using the Y chromosome in epigenetic analyses to better understand male-specific aging and disease mechanisms.

This study analyzed the genetic variations of the KAP20-1 gene in Chinese Tan sheep lambs and found that the G variant was linked to an increased mean fibre curvature in their fine wool fibres, potentially influencing breeding strategies for this wool trait.

This study found significant associations between PCOS susceptibility and specific genetic variants in the APOA5 and PLIN1 genes among Western Saudi women, identifying novel alleles and genotypes that may influence PCOS risk and related clinical characteristics.

In this study, the researchers found that rare genetic variants make a minor contribution to male-pattern hair loss risk, identifying five significant gene associations, including novel genes, and noting a shared basis with monogenic hair loss disorders.

In this study, researchers conducted whole-genome resequencing of eight sheep breeds to identify additional genes associated with wool fineness, revealing 269 genes in fine wool and 319 in coarse wool breeds that are linked to significant traits and pathways.

This study found that ESR1 gene polymorphisms may be linked to hormonal imbalances in young women with hyperandrogenism, potentially affecting bone mineral density indirectly.

This review compiles existing information on the pathogenesis of androgenetic alopecia, highlighting its genetic, hormonal, and environmental factors, but reports no new clinical findings.

This study using Mendelian randomization suggests lifelong increased free testosterone in males may have beneficial effects such as increased bone mineral density and decreased body fat, but also increased risks of prostate cancer and hypertension.

This article contains no research findings; it reports on an online discussion about platelet-rich plasma (PRP) and opinions shared during a conference.

This study identified key genetic regions associated with alopecia areata, highlighting both acquired and innate immune involvement, with a novel link to the upregulation of ULBP ligands in autoimmune disease.

This review examines the interplay of genetics and neuroimmunology in alopecia areata, highlighting its potential to inform broader autoimmunity research, but reports no new findings.

This review discusses case reports of autoimmune diseases following vaccination and the challenges of establishing a clear epidemiological connection, urging further investigation into vaccine-induced autoimmunity.

Alopecia areata is caused by an immune response, and targeting immune cells might help treat it.

A mutation in the KRT74 gene causes tightly curled hair.

This review discusses the disruption of hormonal and metabolic rhythms in polycystic ovary syndrome and explores potential drug targets to address its molecular causes, without providing new clinical results.

This study found that lower testosterone levels in male COVID-19 patients were associated with greater disease severity and longer hospital stays.

This study identified a specific SNP in the CACNB4 gene associated with a higher risk of chemotherapy-induced alopecia in breast cancer patients, which may help develop interventions to improve their quality of life.

This study found that certain T cell-associated genes were upregulated in dogs with Vogt-Koyanagi-Harada syndrome and vitiligo, suggesting a shared immunopathogenesis with humans.

This study identified 24 independent genetic variations and 127 unique genes associated with nociplastic pain, suggesting it is a complex, heritable trait with links to various cognitive and metabolic pathways.
