Senescent melanocytes in nevus skin boost hair growth.

This study observed that nevus melanocytes do not exhibit signs of senescence, suggesting that their growth arrest is due to cell interactions and not directly caused by BRAF activation.

This study suggests that the growth arrest of nevus melanocytes is not due to oncogene-induced senescence but rather to collective cell interactions, similar to those in normal tissue size regulation.

This study suggests that while cellular senescence impairs epidermal stem cells in aging, it also serves an essential role during embryonic development, highlighting its dual functional nature.

This study found that H-Ras activation in aged mouse skin leads to increased dysplasia and progression to in situ squamous cell carcinoma, highlighting an age-linked connection between immune changes, senescence, and cancer risk.

This review discusses the senescence–stemness connection in cellular biology and reports no new findings, highlighting implications for both tissue repair and aggressive cancer behavior.

This workshop review discusses the dual role of cellular senescence in cancer, highlighting both its anticancer effects and pro-tumorigenic potential, while reporting no new research results.

This review examines cell senescence pathways in melanocytes, highlighting the involvement of telomere attrition, the p16/RB pathway, and cAMP signaling in the context of melanoma development, but reports no new findings.

In this study, Cyanidin 3-O-arabinoside was found to protect against DHT-induced dermal papilla cell senescence and mitochondrial dysfunction in androgenetic alopecia, restoring hair growth in mouse models.

In this study, sandalore was found to activate OR2AT4, which inhibits senescent cell traits and restores proliferation in human keratinocytes, suggesting potential anti-aging applications.

This review discusses the complex correlation between cellular senescence and PCOS, emphasizing senescence markers, mechanisms, and potential anti-senescence therapies, but reports no new clinical results.

This study found that targeting IL-6, IL-1, and CCR6 signaling pathways may effectively reduce irradiation-induced alopecia and dermatitis in radiotherapy patients.

This study found that adipose-derived stem cell extracellular vesicles reduced wrinkles and promoted cell proliferation in UVB-induced photoaging in mice by decreasing oxidative stress and inflammation.

This study found that in mice, low-dose irradiation causes stem cells in hair follicles to undergo chromatin alterations, which may eventually lead to long-term functional loss in tissues or organs.

This study suggests that epigallocatechin gallate (EGCG) from green tea may counteract DHT-induced hair follicle damage by modifying the miRNA expression profile in human dermal papilla cells.

In this study, researchers discovered that the HrasG12V oncogenic mutation in murine skin epithelial cells initially promotes progenitor cell renewal but later leads to a balanced differentiation, stabilizing clone growth.

This study shows that inhibiting anti-apoptotic proteins BCL-W and BCL-XL can specifically induce apoptosis in senescent cells, suggesting a potential strategy for treating age-related pathologies.
