Research ArticleOpen accessIn the keywordsEpigenetic Regulation of Extracellular Matrix Remodeling in Skin Aging: Mechanisms and InteractionsJiguang Yang, Yusong Shi, Xiaoqing YanSkin aging results from complex interactions between genetic factors, environmental stressors, and epigenetic modifications that regulate extracellular matrix (ECM) remodeling. Accumulation of senescent cells impairs tissue regeneration through mechanisms including telomere shortening, reactive oxygen species accumulation, and ultraviolet (UV) radiation exposure. While epigenetic pathways regulate skin homeostasis, regeneration, and senescence, the specific epigenetic changes occurring during UV exposure, chronological aging, … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 15 Feb 2026 · 1,458 accessesView PDF Cite

Research NotesOpen accessIn the abstractNuciferine Attenuates Cigarette Smoke-Induced Senescence in HepG-2 Cells via the miR-217/SIRT1/Nrf2 PathwayYun-Hong Zhao, Yi-Meng Ge, Wei-Jia Xu et al.The lotus leaf, widely used in both medicine and cuisine, contains bioactive compounds with therapeutic potential. Nuciferine (NF), an active constituent of significant importance, is extracted from the lotus leaf. The present study sought to uncover the molecular pathways through which Nuciferine (NF) mitigates cellular senescence triggered by Cigarette Smoke Components (CSCs) in HepG-2 cells, employing an experimental model where … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 4 Oct 2025 · 2,296 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAge-Dependent Variation of Telomere Length and DNA Damage in ChickenMaxim S. Makarenko, Alexander V. Usatov, Lyubov V. Getmantseva et al.Birds are unique models for molecular studies on aging processes and cellular senescence because of their slow rates of aging and comparatively long life spans among homoeothermic animals. The study aimed to examine the relative telomere length and amount of nuclear, mitochondrial DNA lesions in hens of different ages and to find out the correlation between these biomarkers of aging. … …OnLine Journal of Biological Sciences, Vol. 17, Issue 4 · 14 Dec 2017 · 7,505 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Arid3a Transcription Factor Rescues Natural and RAS-V12-Induced Senescence Via a Rb-Dependent PathwayChristian Schmidt, Dongkyoon Kim, Shawn Mathur et al.Primary cells are protected against oncogenic events by undergoing premature cellular senescence—an irreversible cell cycle arrest activated by mitogenic signaling as well as by overexpression of tumor suppressors, including p16INK4A, p53 and PML. In the human, downregulation of Dril1/E2F-BP1, a transcriptional regulator of E2F, promotes PML-dependent premature senescence and bypass of ant-iproliferative signaling by p19Arf/p53/p21Cip1 and p16INK4a to prevent both … …American Journal of Immunology, Vol. 13, Issue 4 · 4 Nov 2017 · 8,396 accessesView PDF Cite
