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 abstract contains fragmented and promotional text about various topics, including Hondrostrong and unrelated products, without presenting any new research findings.

This review discusses hair follicle organoids as emerging models for studying hair biology and disorders, emphasizing their promise for bridging basic research and clinical applications, but reports no new results.

This study found that overexpression of ornithine decarboxylase and activated Ha-ras together led to a high rate of tumor development in a mouse model without additional carcinogens.

This study suggests that polyamines regulate CK2 enzyme activity and its subcellular distribution, as demonstrated in mouse models and cell cultures with elevated levels of ornithine decarboxylase.

This study developed new immortalized keratinocyte cell lines lacking COL7A1 using CRISPR/Cas9 technology, providing a valuable model to explore the biology and treatment options for recessive dystrophic epidermolysis bullosa.

This laboratory study found that nonanal, a plant scent compound, may stimulate growth factors and cell proliferation in human hair follicle dermal papilla cells, suggesting a cAMP-mediated mechanism.

This case report identified trichorrhexis nodosa in a patient, likely due to the topical use of an ayurvedic preparation containing calcium hydronide.

This study reported that a three-dimensional hydrogel culture system supports the growth and maintenance of distinct dermal papilla cell types, crucial for skin reconstitution assays in neonatal mice.

This study reported a 3.86% prevalence of PCOS among tenth-grade schoolgirls in Guangzhou, with higher rates observed in obese girls compared to their lean counterparts.

This study established a method for selecting human hair follicle stem cells through quick-adherence to collagen, and found that β-catenin plays a role in their proliferation and differentiation.

In this study, researchers synthesized the fictional compound 1-hydroxyindole and discovered its potential medical applications, including anti-aging properties, itch relief for atopic dermatitis, and as a stronger treatment for dementia compared to cilostazol. Additionally, they found that 1-methoxyindole derivatives function as anticancer agents in diets.

This study found that FZD2 is crucial for hair follicle formation and postnatal growth in mice and has a novel role in regulating early epidermal development, including stratification and cornification.

This study found that inhibiting the enzyme ornithine decarboxylase (ODC) prevented UVB-induced basal cell carcinomas in a mouse model, suggesting ODC is a potential target for chemoprevention strategies.

In this study, researchers observed that RE-ORGA, a preparation from Korean herbs, may help alleviate androgenic alopecia by promoting human dermal papilla cell proliferation, reducing 5α-reductase enzyme levels, and displaying anti-inflammatory properties, suggesting potential regulation of androgen receptor sensitivity.

This study found that nestin-expressing unipotent progenitor cells capable of differentiating into outer root sheath keratinocytes are present during hair follicle development and in adult hair follicles.

This study found that obese Egyptian women with polycystic ovary syndrome had significantly lower serum 25-OH vitamin D levels compared to non-obese women with the condition.

This study found that TPA treatment transiently induces high levels of ODC in mouse epidermal cells, particularly around hair follicles, with localization reduced by retinoic acid or cycloheximide pretreatment.

This study found that the hair interior defect in AKR/J mice is linked to a mutation in the Soat1 gene, which disrupts SOAT1 protein expression and affects lipid metabolism critical for normal hair formation.

This study identifies iRhom2 as a crucial regulator of hair follicle differentiation, showing that the iRhom2Uncv mutation leads to dysplasia and reduced TACE maturation, resulting in a hairless phenotype in mice.

This study reported that overexpressing ornithine decarboxylase in C57Bl/6 mice increased their sensitivity to tumor promotion by TPA, a change reversible by doxycycline treatment.

This study found that using ionic liquid for specimen preparation allowed for observation of dermal papilla cells and their cilia in near-living conditions, reducing damage typically caused by conventional preparation methods.

This research detailed a single-cell atlas showing dynamic hair follicle stem cell states associated with the hair cycle during aging in mice, highlighting differences in chromatin landscape linked to stem cell differentiation and quiescence, and providing a foundation for future exploration of aging reversal.

This study found that the protein hairless acts as both a corepressor and coactivator of the vitamin D receptor, influencing gene transcription in a ligand-selective manner.

This study found that HPV16 oncogene expression in multipotent epithelial stem cells led to abnormal mobilization, altering their quiescence without affecting other stem cell markers, suggesting a distinct stem cell compartment.

This article reviews the history and characteristics of the rare nude phenotype SCID, primarily distinguished by severe T cell immunodeficiency and notable skin and hair abnormalities, but reports no new clinical findings.

This study found that 40.42% of undergraduate medical students aged under 25 had early canities, with grade I being the most common.

This article discusses various methods, including Skincell Advanced and Mesoderm youth activator cream, for improving skin appearance and reducing signs of aging but reports no new research findings.
