Research NotesOpen accessEvery word in the titleNuciferine 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

Review ArticleOpen accessEvery word in the titleSIRT1 Controls Lipid Metabolism Under Physiological and Pathological Conditions: Implications in AtherosclerosisAnastasia Vladimirovna Poznyak, Ludmila Viktorovna Nedosugova, Victoria Alexandrovna Khotina et al.This comprehensive review examines the multifaceted role of Sirtuin 1 (SIRT1) in cellular metabolism and energy regulation, with a particular focus on its involvement in lipid metabolism and glucose regulation. Additionally, SIRT1's impact on several pathologies, including osteoarthritis, diabetes, and cardiovascular disease, is explored. Notably, this review sheds light on the unique contribution of SIRT1 in the development and progression … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 7 Jun 2024 · 4,739 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleRelative Transcription Expression Level of SIRT1, SIRT2 and SIRT3 in Correlation to the Expression of a Set of Selected Cancer Related Genes in Human Breast CancerHamdy Swelim, Omnia Mansour, Salah Abdel-Rahman et al.Mammalian Sirtuins have been shown to perform distinct cellular functions and deregulated expression of these genes was reported to be involved in the development of various malignancies including breast cancer. An increasing number of evidence indicates that Sirtuins have both tumor promoter and tumor suppressor functions. However, the roles of Sirtuins have not been well-studied in breast cancer. In the … …OnLine Journal of Biological Sciences, Vol. 18, Issue 2 · 18 Jan 2018 · 7,476 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSeparation, Purification and Anti-aging Activity of Tobacco PolysaccharidesMengyue Huang, Jingwu Song, Shuaishuai Chang et al.To separate tobacco polysaccharides and investigate their antioxidant and anti-aging properties, crude tobacco polysaccharides were extracted from raw tobacco using hot water, followed by purification through DEAE-52 cellulose column chromatography. The molecular weight and monosaccharide composition of the isolated polysaccharides were analyzed using HPGPC and HPLC. The antioxidant activities of these tobacco polysaccharides were tested using DPPH, ABTS, hydroxyl radicals … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 1 · 15 Jan 2025 · 5,103 accessesView PDF Cite
