This study used transcriptome analysis to explore the genetic mechanisms behind the development and seasonal variation of nuptial pads in R. chensinensis, identifying key genes and processes that suggest the pads' development involves complex regulatory pathways, particularly those related to cell cycle and hormone synthesis.

This review discusses genetic and epigenetic mechanisms that may contribute to aging and presents models suggesting that chromosomal changes could play a key role in the aging process; it reports no new experimental findings.

This systematic review and meta-analysis found 30 genetic loci associated with skin ageing phenotypes, noting shared biological pathways in aspects like pigmentation and wrinkling; researchers suggest further studies targeting the same SNP across populations could clarify these associations.

This study found that cataracts, hair changes, short stature, and low bodyweight are key indicators for diagnosing Werner syndrome in patients under 30, differing from older age group symptoms.

This review discusses the mechanisms and treatment strategies for age-related hair changes, such as androgenetic alopecia and hair graying, and reports no new clinical results.

This case report described a 9-year-old girl initially suspected to have complete androgen insensitivity syndrome, whose laboratory tests later suggested an alternative diagnosis involving atypical steroid metabolism patterns and hormonal responses.

This review explores the complex pathophysiology of androgenetic alopecia, highlighting genetic factors, androgen metabolism, and emerging therapies such as platelet-rich plasma and low-level laser therapy, but notes that no ultimate cure exists and treatments focus on slowing progression and promoting hair growth.

In this review, researchers discuss the factors contributing to early graying, such as genetic predisposition, oxidative stress imbalance, and nutrient deficiencies, and highlight potential restoration methods involving palmitoyl tetrapeptide-20 and the endocannabinoid system in hair follicles.

This article discusses a proposed "Darwinian" model of carcinogenesis and emphasizes that cancer prevention involves more than avoiding mutagens, as gene-environment interactions are complex and non-linear.

This review discusses the mechanisms of skin aging, highlighting the roles of stem/progenitor cells, genetic and environmental factors, and suggests potential for cell-based therapies, but reports no new experimental findings.

This study reports that dynamic interactions between stem cells and their niche, influenced by macro-environmental factors, regulate regenerative behavior in integument pattern formation.

This study found that specific genetic changes in both coding and noncoding regions may have independently driven the evolution of hairlessness in various mammalian species through accelerated evolution.

This chapter discusses genetic polymorphisms related to phenotypes that differentiate between populations and reports no new results; it highlights the role of DNA technology in understanding human adaptation history.

This research highlights advancements in understanding and treating psoriasis, finding that targeted therapies like IL-17 and IL-23 inhibitors show promise, but challenges such as adverse events, treatment resistance, and the need for personalized approaches remain.

This study developed a deep learning-based tool to quantify individual hair fibers in mice, revealing distinct hair phenotypes linked to hormonal, genetic, and age-related factors, and suggesting its potential for new diagnostic methods through hair analysis.

This review discusses recent advances in the understanding of follicular melanogenesis and its pathological changes, particularly how these changes are associated with specific disease phenotypes, but it reports no new results.

This article reviews various causes and treatments for alopecia, including nutritional deficiencies, stress, and hormonal changes, and reports no new clinical results.

This review discusses the management of hair loss in midlife women, focusing on female pattern hair loss, hair shaft alterations from hair care, and telogen effluvium, and reports no new research findings.

This case report documents acquired progressive kinking of the hair in a prepubertal boy but does not provide new clinical results.

This review discusses the importance of early diagnosis and the management of hidradenitis suppurativa, reporting no new clinical results but highlighting current therapeutic approaches and need for collaboration in treatment.

This review presents updated tables of mouse mutants with hair growth abnormalities to aid in understanding the molecular mechanisms of human hair disorders, but reports no new clinical results.

This article reviews the generation of complex integument patterns through genetic, chemical, and environmental influences, with applications in tissue engineering, but reports no new experimental results.

Genetic factors alone might not cause pemphigus vulgaris; other factors like birth complications and puberty may trigger it.

This review discusses the effects of pregnancy on melanocytic nevi and reports no new clinical results; it suggests that changing nevi during pregnancy should be evaluated similarly to those in nonpregnant patients.

This study reported a previously undescribed form of hereditary hypotrichosis in a family, characterized by childhood-onset hair loss, morphea, and probable autosomal dominant inheritance.

Up to 50% of scalp hair can be lost before it appears thin, and treatment is only needed for hair loss caused by diseases or deficiencies.

Childhood hair and scalp disorders can be managed with treatments like cortisone and corticosteroids.

This study reviews current research to better understand how various environmental and lifestyle factors, collectively known as the exposome, impact hair health and aging, acknowledging that the detailed mechanisms remain partially understood.

This study found significant differences in alopecia rates among rhesus macaques based on their previous housing facilities, suggesting that factors beyond current environment may influence alopecia.

This book discusses current research on polycystic ovary syndrome, including diagnosis, management, and the impact of lifestyle changes, without reporting new clinical results.
