Uncontrollable cancer cell growth is characterized by the maintenance of cellular homeostasis through continuous accumulation misfolded proteins and damaged organelles. This review delineates roles two complementary synergistic degradation systems, ubiquitin–proteasome system (UPS) autophagy-lysosome system, in organelles for intracellular recycling. We emphasize interconnected decision-making processes systems maintaining homeostasis, such as biophysical state substrates, receptor oligomerization potentials (e.g., p62), compartmentalization capacities membrane structures). Mitochondria, hubs respiration metabolism, are implicated tumorigenesis. In subsequent sections, we thoroughly examine mechanisms mitochondrial quality control (MQC) preserving human cells. Notably, explored relationships between dynamics (fusion fission) various MQC processes—including UPS, proteases, mitophagy—in context repair pathways. Finally, assessed potential targeting (including molecular chaperones, dynamics, mitophagy biogenesis) therapeutic strategies. Understanding underlying may offer novel insights future therapies. highlights UPS degrading proteins, emphasizing substrate states, oligomerization, homeostasis. Innovatively links coordination to examining interplay these pathways varying degrees damage.

Abstract Telomere dysfunction is a well-known molecular trigger of senescence and has been associated with various age-related diseases, including atherosclerosis. However, the mechanisms involved have not yet elucidated, extent to which telomeres contribute atherosclerosis unknown. Therefore, we investigated mechanism metformin-induced telomere stabilization ability metformin inhibit vascular smooth muscle cell (VSMC) caused by advanced The present study revealed that inhibited phenotypes in VSMCs. Metformin increased phosphorylation AMPK-dependent PGC-1α thus telomerase activity protein level TERT OA-treated Mechanistically, AMPK only enhanced function but also TERT, whereas knockdown accelerated development senescent VSMCs regardless treatment. Furthermore, vivo results showed attenuated formation atherosclerotic plaque markers aortas HFD-fed ApoE KO mice.

The role of mitochondria as the electric engine cells is well established. Over past two decades, accumulating evidence has pointed out that, despite presence a highly active glycolytic pathway (Warburg effect), functional and even upregulated mitochondrial respiration occurs in cancer to meet need high energy biosynthetic demand sustain their anabolic growth. Mitochondria are also primary source intracellular ROS. Cancer maintain moderate levels ROS promote tumorigenesis, metastasis, drug resistance; indeed, once cytotoxicity threshold exceeded, trigger oxidative damage, ultimately leading cell death. Based on this, metabolic functions generation considered attractive targets synthetic natural anticancer compounds. Tocotrienols (TTs), specifically δ- γ-TT isoforms, vitamin E-derived biomolecules widely shown possess striking properties since they regulate several molecular pathways. Herein, we provide for first time an overview reprogramming redox homeostasis perturbation occurring cells, highlighting involvement TTs. This sheds light use these compounds promising preventive or therapeutic approach novel strategies.

Abstract NADH dehydrogenase [ubiquinone] iron-sulfur protein 3 (NDUFS3) is the core subunit of respiratory chain complex I (CI). We found NDUFS3 were abnormally elevated in human melanoma and promoted proliferation. Furthermore, could promote oxidative phosphorylation (OXPHOS) pentose phosphate pathway (PPP), as well attenuated glycolysis. As NDUFS3-mediated metabolic changes OXPHOS glucose metabolism, cells produced more ATP, resulting inhibition AMP kinase (AMPK). AMPK induced phosphoribosyl pyrophosphate synthetase1 (PRPS1) phosphorylation, which resulted suppressed PRPS1 activity. Briefly, NDUFS3-AMPK-PRPS1 signaling axis coupled OXPHOS, purine nucleotide biosynthesis to regulate Our study highlighted an unrecognized role for melanoma, might be used a potential therapeutic target treatment this type cancer.

Mitochondria are recognized as a central metabolic hub with bioenergetic, biosynthetic, and signaling functions that tightly control key cellular processes. As crucial component of mitochondrial biogenesis, peroxisome proliferator-activated receptor gamma coactivator 1α (PGC-1α) is involved in regulating various pathways, including energy metabolism reactive oxygen species homeostasis.
