This study used bioinformatics to explore molecular differences in testicular and ovarian responses to SARS-CoV-2, identifying genes that could be associated with sex differences in infection outcomes.

This review discusses the role of immune cells in mammalian hair cycle control and highlights their potential relevance to human hair cycling disorders, reporting no new clinical findings.

This study found that a cocktail of three proteins from embryonic skin can enable adult fibroblasts to regenerate hair follicles by altering gene expression and activating regenerative signaling pathways.

This study found similarities in the regeneration processes of MRL mouse ears and axolotl limbs, involving G2 cell cycle arrest and nerve-dependent mitosis, but the role of p21 in axolotl limb regeneration remains uncertain.

In this review, the authors discuss how understanding and co-regulating multiple signaling pathways could lead to effective regeneration of functional hair cells, highlighting current achievements and future approaches such as small molecule drugs and gene therapy for treating sensorineural hearing loss.

In this study, researchers found that deleting Caspase-9 in hair follicle stem cells delayed apoptosis, leading to accelerated wound repair and new hair follicle regeneration by maintaining apoptotic cells as signaling centers.

This study found that the ablation of Esrp1 and Esrp2 disrupts epithelial tight junctions by affecting Arhgef11 isoform expressions, highlighting a potential mechanistic link between splicing alterations and epithelial barrier defects.

This study found that in mice lacking EGFR, elevated Wnt signaling disrupts hair follicle development by affecting cell proliferation and differentiation, revealing a critical role for EGFR in regulating these processes.

This study created a humanized mouse model of hereditary vitamin D-resistant rickets that lacks alopecia, indicating the mutant receptor's potential to explore the syndrome's characteristics beyond vitamin D binding.

This review examines patents and publications on steroid sulfatase inhibitors since 1999 and reports no new clinical results, highlighting their potential for treating estrogen- and androgen-driven conditions.

In this study, fractional laser treatment was observed to reverse age-related gene expression changes in skin and enhance dermal remodeling, further improved by multiple treatments.

In this study, researchers observed that African spiny mice, Acomys cahirinus, are capable of regenerating skeletal muscle in dermal wound sites, unlike common mice, Mus musculus.

This study reports that compound heterozygous loss-of-function mutations in the HEPHL1 gene in a child were associated with abnormal hair and cognitive issues, linking altered ferroxidase activity to hair disorders.

This study suggests that controlling light exposure can influence cashmere growth by triggering hair follicles to enter their active growth phase sooner, potentially involving the CSDC2 gene as a key regulator.

Researchers found an RNA transcript that might help control a growth factor linked to tumor development.

This review explores recent insights into how intrinsic gene oscillations and molecular interactions in hair follicle stem cells contribute to their regenerative potential, with potential implications for regenerative medicine, but reports no new clinical results.

This study generated FGF5-knockout Dorper sheep using the CRISPR/Cas9 system, resulting in significantly increased fine-wool and active hair-follicle density, and explored downstream signaling pathways for potential applications in androgen alopecia treatment.

This study found that biallelic LSS mutations lead to congenital hypotrichosis and cataracts, with each tissue-specific loss of function observed in mouse models.

This article reviews the roles of lesser-known secreted phospholipase A2 isoforms in various biological processes, such as immune suppression, metabolic regulation, epidermal hyperplasia, and male reproduction, without reporting new clinical findings.

This study found that KLF4 expression in mouse hair follicle stem cells is important for effective cutaneous wound healing, with its knockdown leading to reduced stem cell populations and delayed healing.

In this study, researchers found that the EDMTFH protein is present in specific layers of the chicken embryo skin and feathers, suggesting its role in feather mechanics and development.

This review examines the Wnt signaling pathway's role in regeneration across key model species, but it reports no new findings and highlights the need for more research to understand the underlying molecular mechanisms.

This study identified specific germline and somatic mutations in the Phospholipase C Delta 1 gene as high-risk factors for developing hereditary trichilemmal cysts, involving a monoallelic two-hit mechanism.

This study found significant differences in gene expression between newborn and adult skin, with infant skin notably increasing processes related to ECM organization, cell adhesion, and collagen fibril organization.

This review discusses recent findings on the epigenetic regulation of adult stem cells and cancer stem cells, highlighting shared and distinct features, and reports no new clinical results.

This study found that HPV-150 and HPV-151 are rare genotypes with a preference for skin tissue, detected in some cases of skin lesions with generally low viral loads.

This study found that telomere shortening disrupts BMP/pSmad/P63 signaling, leading to skin atrophy via Follistatin up-regulation, and suggests potential therapeutic targets.

This study suggests that miRNAs, particularly miR-195-5p, may regulate the loss of hair follicle inductivity in cultured dermal papilla cells by suppressing the Wnt/β-catenin pathway.

This study suggests that the protease HAT-L4 plays a significant role in maintaining epidermal barrier function to prevent body fluid loss, as its absence in mice led to increased fluid loss and higher mortality.

This study reviews the mechanisms by which SARS-CoV-2 may impact male fertility, noting potential disruptions in spermatogenesis and hormone secretion, and underscores the need for follow-up in recovered men.
