In this study, researchers found that depleting mtDNA in mice caused skin wrinkles and hair loss but restoring mitochondrial function reversed these effects, highlighting mtDNA's significant role in skin and hair health.

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 review discusses the roles and mechanisms of Wnt signaling in embryonic and adult stem cells and its association with cancers, and reports no new experimental findings.

This study identified a novel G207E STING mutation associated with severe inflammatory symptoms and suggested that common polymorphisms in TMEM173 and IFIH1 may modify the phenotype in affected individuals.

This article reviews the clinical and diagnostic features of hair shaft disorders, emphasizing the role of structured patient assessments and the avoidance of hair trauma, but reports no new results.

This mini-review discusses human hair follicle development and summarizes genetic disorders linked to abnormalities in hair follicle morphogenesis, structure, or regeneration, but reports no new experimental results.

This study found that transient mtDNA double strand breaks in mice accelerated aging in certain tissues through increased reactive oxygen species, independent of p21/p53 pathway mediation.

This study suggests that UMPP activation is a key signaling pathway in differentiating primary and secondary hair follicles in cashmere goats.

This review discusses how the p53 tumor suppressor gene helps maintain adult tissue homeostasis by promoting the removal of DNA-damaged cells, with implications for treating age-related diseases and p53-deficient cancers; it reports no new results.

Martin-Perez et al. show that rapamycin's beneficial effects in a mouse model of Leigh syndrome are linked to the downregulation of protein kinase C.

This study found that colchicine treatment significantly reduced hair fiber elongation in cultured hair follicles and altered protein expression and activity in dermal papilla cells, suggesting a role for the ubiquitin-proteasome system in its effects.

This review discusses the mechanisms governing epidermal stem and progenitor cell differentiation, emphasizing the balance necessary for maintaining skin barrier function, and reports no new experimental findings.

This review discusses spironolactone's new roles in tumor immunosurveillance, DNA repair inhibition, and viral infection suppression, highlighting its potential to extend uses beyond traditional applications, but reports no clinical results.

This study reports that synthetic carbohydrate receptors effectively inhibit Zika virus infection in cell cultures by blocking early stages of viral entry.

This study reports that chemically induced short anogenital distance in male rat fetuses involved distinctive transcriptional changes, suggesting roles for estrogen and Wnt2 signaling in anogenital tissue development.

This review discusses the development of the MATH+ treatment protocol for COVID-19 patients, detailing its scientific and clinical rationale, but reports no new experimental findings.

This study suggests that the rs2075876 variant in the AIRE gene may significantly increase susceptibility to alopecia areata in the examined male population.

This study found that in a mouse model of Leigh syndrome, rapamycin alters brain proteome and may extend survival by targeting protein kinase C.

In this study, the researchers observed that biotin administration in biotin-deficient children with alopecia eliminated certain membrane proteins from their blood, suggesting that biotin might regulate these proteins' expression.

This study found that treating asymptomatic or mild COVID-19 with cepharanthine did not significantly reduce the time to a negative test result, though 60 mg/day showed a non-significant trend needing further validation.

In this study, researchers found that Elastic Net DNA methylation clocks are not accurate for distinguishing between individuals or identifying health markers, but measuring biological "noise" in stable cytosines may serve as a potential biomarker of aging and disease.

This review discusses genetic mutations associated with Hutchinson-Gilford progeria syndrome and reports no clinical results; the authors emphasize the importance of cardiovascular monitoring in management.

In this review, researchers explored the multifaceted role of NF-κB signaling in various biological processes and diseases, including its interactions with other pathways, and discussed possible therapeutic approaches targeting this pathway for treating conditions like cancer, autoimmune disorders, and COVID-19.

In this study, 60 mg/day of Cepharanthine significantly reduced the time to a negative COVID-19 test among de novo infected patients with good compliance, though 120 mg/day showed no such effect.

This study reports that a novel gain-of-function mutation in TMEM173, combined with polymorphisms in TMEM173 and IFIH1, results in a distinct clinical phenotype with features of SAVI, including alopecia and photosensitivity.

This study found that multiple vitamins, including B6, increased the number of growing follicles in newborn mouse ovaries in vitro. VB6 promoted primordial follicle activation via the PI3K/Akt signaling pathway in both cultured mouse and human ovarian tissues.

In this review, researchers examined the link between microorganisms and vitiligo, highlighting how microbes might impact the disease's development and suggesting avenues for better treatment strategies based on these interactions.

This review explores how radiation-induced hair graying can be used as a model to study the mechanisms behind hair graying, focusing on cellular senescence and potential therapeutic targets to address age-related changes. Results are not provided.

This study found that vimentin is essential for proper wound healing and cell growth by influencing EMT signaling and mTOR activity in mice.

In this study, type I interferon response-related genes activated by RIG-1 and IL-17 signaling pathways were significantly up-regulated in both hair follicles and skin tissues affected by chronic discoidal lupus erythematosus.
