This study suggests that hair loss was a metabolic adaptation allowing hominids to evolve larger brains by alleviating dietary restrictions on essential amino acids for hair and brain development.

This study indicates that reduced activity of the matriptase-prostasin proteolytic cascade is likely the cause of human autosomal recessive ichthyosis with hypotrichosis, as demonstrated using a novel mouse model.

In this study, researchers found that the absence of type I or type II keratins in mice leads to severe skin barrier defects, highlighting keratins' crucial role in epidermal structure and function.

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 suggests that the structure and function of the inner root sheath in mammalian hair may have evolved from simpler forms seen in monotremes, aiding in hair exit without damaging the epidermis.

This narrative review explores the molecular mechanisms driving skin development and their role in skin diseases, emphasizing how disruptions in these pathways can lead to conditions like congenital disorders and cancers, potentially guiding new targeted therapies.

This review discusses the roles of glucocorticoids and glucocorticoid receptors, and it explores potential genetic and non-genetic causes of glucocorticoid resistance or hypersensitivity syndromes, reporting no new clinical results.

This literature review highlights the importance of understanding the mechanisms behind the gradual mosaic loss of the Y chromosome (mLOY) in men, its association with various health conditions like cardiovascular diseases and cancer, and its potential as a marker for age inference.

This study found that Fgf5 mutant mice exhibited longer hair, particularly in males, likely due to a prolonged anagen phase in the hair cycle.

This study found that DHEA along with osteogenic induction medium significantly promotes the osteogenic differentiation and proliferation of human bone marrow mesenchymal stem cells from older individuals.

This study found that the unique crest feather formation in Polish chickens is driven by a 195-bp duplication in the HoxC10 gene region, which alters gene expression by modifying the genomic structure, suggesting a mechanism for diverse integumentary appendages in birds.

In cashmere goats, this study found that reducing miR-361-5p levels activates secondary hair follicle stem cells by upregulating the FOXM1 gene, which in turn stimulates the Wnt/β-catenin pathway, crucial for cashmere fiber morphogenesis.

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.

The researchers reported finding a recessive nonsense variant in the EGFR gene responsible for perinatal lethality in the "Blonde d'Aquitaine" cattle breed, prompting the development of a screening test to help eradicate this genetic flaw.

This study found that exosomes derived from mesenchymal stem cells primed with rapamycin significantly enhanced hair regrowth, hair density, and hair follicle development in depilation-induced mice compared to controls, suggesting a potential therapeutic approach for hair loss.

This study identified novel mitochondrial DNA variations in PCOS patients from Pakistan, which may serve as genetic predisposition markers, highlighting especially the potential pathogenicity of frameshift mutations in the MT-ND2 gene.

This study found that upper-bulge epidermal stem cells in mouse hair follicles are specialized for nerve interactions, crucial for forming tactile sensory units, and influence touch responses via EGFL6 and αv integrin pathways.

This study found that in Arabidopsis thaliana, the interaction between extracellular leucine-rich repeat extensins and the receptor-like kinase FERONIA helps control vacuolar expansion, crucial for cellular elongation.

This study found that ACE2 and TMPRSS2 genes were more highly expressed in tumors of elderly male cancer patients compared to healthy individuals, with notable differences across age and gender.

This study in Gansu alpine fine-wool sheep identified two SNPs in the KRT71 gene that significantly affect wool length, with distinct expression patterns observed in hair follicles, suggesting KRT71 as a candidate gene for enhancing wool production traits.

This study found that in Pomeranians with Alopecia X, key genes in the Wnt and Shh signaling pathways and stem cell markers are downregulated, which may explain the absence of anagen hair follicles.

This study identified dual epithelial and mesenchymal traits in dermal sheath cells during wound repair, suggesting they could be targeted to enhance healing.

This study found that recombinant oleosin-hFGF5 expressed in Arabidopsis can inhibit hair regeneration by decreasing the proliferation of hair follicle epithelial cells.

This review synthesizes current knowledge on choriogenesis, the final stage of oogenesis in insects, by exploring the role of follicle cells, regulatory mechanisms of gene expression, and the biochemical makeup of the eggshell, while also highlighting structural diversity and adaptations across insect species.

This report describes two cases of glucocorticoid resistance syndrome highlighting genetic diversity; one patient improved with low-dose dexamethasone despite negative genetic testing, while the other is monitored with a novel NR3C1 variant.

This review discusses the potential of biomimetic synthetic vesicles to advance precision diagnostics and medicine by combining the beneficial properties of naturally occurring extracellular vesicles and synthetic nanoparticles, although no new clinical results are reported.

This review discusses the potential of natural products to induce ferroptosis as a promising therapeutic strategy for non-small cell lung cancer and reports no clinical results; the authors highlight the need for further comprehensive studies.

This study identified three hub genes—BMP4, POSTN, and WNT5A—that are closely associated with keloid fibroblast hyperplasia, suggesting they may serve as potential biomarkers for inhibiting this condition. Further research is necessary to fully understand their roles in keloid development.

This review outlines key considerations for designing fluorescence microscopy experiments in cell biology, discussing the importance of hardware availability, suitability of biological models, and imaging agents to achieve high-resolution and informative images.

Women with PCOS often experience depression and anxiety, affecting their quality of life.
