Autophagy warburg effect. To date, the reciprocal effects of these pathways have not yet been elucidated. The specific mechanism underlying the interaction of autophagy and the Warburg effect in PTC remains unclear, therefore, we focused on the regulatory axis of the SIRT6-autophagy-Warburg effect. Aug 28, 2020 · In conclusion, we identified a SIRT6-ROS-ER stress-autophagy-GLUT1-Warburg effect axis in PTC, which may provide a new therapeutic target. In direct support of this notion, we identified a loss of stromal caveolin-1 as a marker of oxidative stress, hypoxia, and autophagy in the tumor microenvironment, explaining its powerful predictive value. Warburg hypothesized that cancer growth is Aug 28, 2020 · The specific mechanism underlying the interaction of autophagy and the Warburg effect in PTC remains unclear, therefore, we focused on the regulatory axis of the SIRT6-autophagy-Warburg effect. The Mia-Paca-2 and AsPc-1 cell lines were cultured under normal Oct 25, 2020 · Again, any dysfunction in mitochondria triggers autophagy/mitophagy in CAFs that subsequently promotes reverse Warburg effect by agravating HIF-1α, and NF-kB. The association of the Warburg effect in tumor and stromal cells to cancer-related autophagy is of significant relevance in experimental therapeutics. Therefore, this study was designed to investigate the relationship between these factors in vitro and may provide therapeutic targets in the future. It is also accompanied with the activation of antioxidant defence by encouraging the up-regulation of antioxidant enzymes (peroxiredoxin-1) and antiapoptotic proteins (TIGAR) (Martinez May 4, 2018 · The Warburg effect describes a hallmark of cancer where glycolysis results in lactate production even in aerobic conditions [1, 3, 4]. Nov 1, 2020 · Dr Otto Heinrich Warburg proposed this abnormal metabolic behaviour of tumour cells in 1920. Furthermore, Warburg reported that tumourigenic cells exhibit defective mitochondrial OXPHOS that results in switching metabolic energy production to glycolysis. . Current insight revealed aerobic glycolysis supports various biosynthetic pathways and, consequently, the metabolic requirements for proliferation. Autophagy is a key contributor to cellular homeostasis and metabolism. We define and describe the Warburg effect and the newly suggested “reverse” hypothesis. Materials and Methods Cell Culture and Regents TPC-1 and K1 cells (human PTC cell lines) were obtained from the University of Colorado Cancer Center Feb 28, 2025 · Autophagy and the Warburg effect are two common pathways in pancreatic ductal adenocarcinoma (PDAC). Aug 28, 2020 · In ovarian cancer, quercetin induces protective autophagy, and apoptosis by activating ER stress through the p-STAT3/BCL-2 axis (14). May 4, 2018 · Among the cell death machinery is autophagy, a compensatory mechanism whereby energy is produced from damaged and/or redundant organelles and proteins, which prevents the accumulation of waste products, thereby maintaining homeostasis. Autophagy is a highly regulated-cell pathway for degrading long-lived proteins as well as for clearing cytoplasmic organelles. Nov 21, 2023 · In 1923, Otto Warburg published his landmark study, in which he described his seminal observations related to metabolic shifts in cancer, often referred to as the Warburg effect. Previously, it was thought the Warburg effect was a consequence of damage to the mitochondria or an adaptation to hypoxic conditions during the early avascular phase of tumor development. Jan 1, 2014 · We define the Warburg effect and the “reverse” hypothesis and we discuss the potential value of modulating autophagy. Aug 12, 2014 · In this review we introduce the autophagy process and its regulation and its selective pathways and role in cancer cell metabolism. In addition, NAC (low concentration) and CQ, previously considered to be tumor inhibitors, were shown to promote tumorigenesis in PTC with high SIRT6 expression by inducing the Warburg effect. This phenomenon illustrates the metabolic switching in tumour cells from oxidative phosphorylation to aerobic glycolysis triggered by an injury to the mitochondrial respiration. wzv2 kl4a x0b t1f u54 vgqi lyo c1x9h uy 5av
