Sirtuin 6 (SIRT6) is a nicotinamide adenine dinucleotide (NAD)-dependent enzyme. It is a novel member of the sirtuin family that has been shown to have an important role in various molecular pathways in glycolysis, cancer, and neurodegenerative responses. Recently, SIRT6 has emerged as a prominent research issue because its biochemical activity and regulation are possibly associated with human metabolism and disease. In this review, we summarized the connection between SIRT6 and glycolytic metabolism; discussed recent developments in the involvement of SIRT6 in a variety of life-threatening illnesses, including cancer, neurodegenerative diseases and cardiovascular disease; and explored possible treatment approaches for those diseases with SIRT6. This review provides insights into the role of SIRT6 in disease.

One hallmark of cancer is the upregulation and dependency on glucose metabolism to fuel macromolecule biosynthesis and rapid proliferation. Despite significant pre-clinical effort to exploit this pathway, additional mechanistic insights are necessary to prioritize the diversity of metabolic adaptations upon acute loss of glucose metabolism. Here, we investigated a potent small molecule inhibitor to Class I glucose transporters, KL-11743, using glycolytic leukemia cell lines and patient-based model systems.

Background: Hypoxia-inducible factor 1 alpha (HIF-1α) and its related vascular endothelial growth factor (VEGF) may play a significant role in atherosclerosis and their targeting is a strategic approach that may affect multiple pathways influencing disease progression. This study aimed to perform a systematic review to reveal current evidence on the role of HIF-1α and VEGF immunophenotypes with other prognostic markers as potential biomarkers of atherosclerosis prognosis and treatment efficacy.
Methods: We performed a systematic review of the current literature to explore the role of HIF-1α and VEGF protein expression along with the relation to the prognosis and therapeutic strategies of atherosclerosis.

: Incomptine A () has been reported to have cytotoxic activity in non-Hodgkin lymphoma cancer cell lines and have effects on U-937 cells, including the induction of apoptosis, the production of reactive oxygen species, and the inhibition of glycolytic enzymes. Also, has cytotoxic activity in the triple-negative subtypes, HER2+, and luminal A of breast cancer cells, with its properties being associated with an effect on the antiapoptotic function of Hexokinase II (HKII). : In this research, we reviewed the altered levels of proteins present in the lymph nodes of male Balb/c mice inoculated with U-937 cells and treated with or methotrexate, as well as mice only inoculated with cancer cells.

While 5-fluorouracil (5FU) plays a central role in chemotherapy for colorectal cancer (CRC), resistance to 5FU remains a major challenge in CRC treatment, and its underlying mechanisms remain unclear. In this study, we investigated the relationship between 5FU resistance acquisition, stemness, and energy metabolism. Among the two CRC cell lines, HT29 cells exhibited glycolytic and quiescent properties, while CT26 cells relied on oxidative phosphorylation (OXPHOS) for energy.

Background/objectives: The avascular nature of the follicle creates a hypoxic microenvironment, establishing a niche where granulosa cells (GCs) rely on glycolysis to produce energy in the form of lactate (L-lactate). Autophagy, an evolutionarily conserved stress-response process, involves the formation of autophagosomes to encapsulate intracellular components, delivering them to lysosomes for degradation. This process plays a critical role in maintaining optimal follicular development.
