This review examines how caloric restriction could promote autophagy to rejuvenate aging stem cells, though the precise molecular mechanisms remain unclear.

The study emphasizes that telomere shortening is identified as the sole cause of aging among the twelve hallmarks and suggests that increasing telomere and rDNA array length in adult stem cells might effectively reverse aging and extend lifespan.

This review summarizes advancements in forensic DNA phenotyping for appearance, ancestry, and age prediction from crime scene samples, reporting no new research findings but highlighting areas needing further research and validation.

This article discusses the relationship between mitochondrial DNA damage and atherosclerosis, suggesting that mtDNA damage may increase plaque vulnerability independent of reactive oxygen species, but reports no new clinical results.

This study found that mitochondrial oxidative phosphorylation in epithelial cells is necessary for proper enamel formation and odontoblast differentiation in developing incisor teeth in K320E-Twinkle Epi mice.

This study found significant variation in tissue mutant load in individuals with the T8993G mutation, which complicates genetic counseling and may inform genotype-phenotype correlations, especially using hair bulb mtDNA analysis.

This review found that current forensic DNA phenotyping panels for biogeographical ancestry and visible traits face significant limitations due to inconsistencies in terminology, genetic understanding, and genotyping technologies, highlighting the need for harmonization and further research.

In this study, researchers discovered that ROR2, a Wnt receptor, plays a crucial role in regulating hair follicle stem cell self-renewal and maintenance, compensating for the absence of β-catenin.

In this study, researchers found that massively parallel sequencing of mitochondrial DNA (mtDNA) can improve information recovery from forensic samples, with successful full region amplification possible from as few as 2,000 mtDNA copies, albeit with variability in heteroplasmy among hair samples from the same donor.

This study demonstrated that gene-corrected 3D skin constructs from RDEB patient-derived iPSCs, grafted onto immunocompetent mice, showed normal collagen VII expression after two months.

This research quantified the fidelity of human mitochondrial DNA polymerase and found it averages 1 error in 440,000 nucleotides, impacting its function related to disease and mitochondrial health.

This study found that in people with leprosy sequelae, ulcers on the lower limbs exhibited decreased microbial diversity and reduced abundance of specific bacteria compared to normal skin, with skin metabolites closely linked to these microbial changes.

This study found that HBV infection altered steroid metabolism in male mice, significantly increasing levels of dehydroepiandrosterone and reducing dihydrotestosterone, which may suppress viral replication by affecting HBV promoter activity.

This study suggests that selenium deprivation in mice accelerates age-related degeneration but paradoxically promotes longevity, potentially decoupling healthspan from lifespan.

This study found that intermittent treatment with FTI lonafarnib and sulforaphane may be a promising therapeutic approach for children with Hutchinson-Gilford progeria syndrome, as it improved the cellular phenotype.

Werner's syndrome causes early aging and increases cancer risk, requiring early diagnosis and symptom management.

In this study, Dguok deficiency in mice led to premature hair greying due to a loss of melanocyte stem cells and mature melanocytes, with increased oxidative stress and cell death; treatment with an antioxidant mitigated these effects, suggesting DGUOK's importance in hair pigmentation maintenance.

This study found that while zebularine did not significantly accelerate wound healing, it improved the quality of restored skin in mice, suggesting potential for further research into epigenetic inhibitors.

This review examines the genetics of acne vulgaris, concluding that stem/progenitor cell maintenance and cellular migration are key processes in its pathogenesis, potentially shifting future treatment strategies beyond traditional antibiotics and retinoids, which have notable side effects.

This review study focused on various in vitro methods to evaluate skin permeation and retention of sunscreens, highlighting the importance of assessing sunscreen penetration due to widespread nanomaterial usage and advancements in cosmetic formulation.

This study found that mice lacking the vitamin D receptor (VDR) developed skin tumors more rapidly than those with normal VDR activity, regardless of 1,25-dihydroxyvitamin D(3) presence.

In this study, researchers found that Notch signaling is crucial for late-stage epidermal differentiation and postnatal hair cycle homeostasis by regulating hair follicle stem cell proliferation and differentiation.

This article reviews the role of vitamin D receptor in protecting the skin from UV radiation-induced damage and tumor formation, but it reports no new clinical results.

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 study suggests that myotonic dystrophies may qualify as segmental progeroid disorders due to molecular and clinical similarities with typical progeroid syndromes.

This review discusses the impact of melatonin and its metabolites on skin aging, summarizing how they may serve as "aging neutralizers" through their anti-oxidative and anti-inflammatory properties, but reports no new clinical results.

This study found that domestic temporary hair dyes may pose a health risk due to their cytotoxic effects on human red blood cells and NIH/3T3 cell lines.

In this study, researchers observed that EGFR deficiency in the epidermis affects gene expression related to cell differentiation and structure, highlighting spatial and temporal roles of EGFR during skin and hair follicle development.

This review highlights recent advances in CRISPR-based lineage tracing methods that can improve our understanding of skin stem cell behavior, regeneration, and disease, with potential applications in organoids and model organisms.

This review explores the detrimental effects of sunlight on the skin’s circadian rhythm and photodamage, noting the potential of natural cosmeceuticals to influence this rhythm, but reports no new results.
