Oncogenic metabolic reprogramming contributes to tumor growth and immune evasion. The intertumoral metabolic heterogeneity and interaction of distinct metabolic pathways may determine patient outcomes. In this study, we aim to determine the clinical and immunological significance of metabolic subtypes according to the expression levels of genes related to glycolysis and cholesterol-synthesis in bladder cancer (BCa).

Lactic acid produced by tumors has been shown to overcome immune surveillance, by suppressing the activation and function of T cells in the tumor microenvironment. The strategies employed to impair tumor cell glycolysis could improve immunosurveillance and tumor growth regulation. Dichloroacetate (DCA) limits the tumorderived lactic acid by altering the cancer cell metabolism.

Cancer cells prefer utilizing aerobic glycolysis in order to exacerbate tumor mass and maintain un-regulated proliferative rates. As a key glycolytic activator, phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3 (PFKFB3) has been implicated in multiple tumor type progression.

Các rối loạn của các quá trình chuyển hóa Các phân tử sinh học được phân thành 4 nhóm chính: các nucleic acid, các protein, các carbohydrat và các lipid. Các con đường chuyển hóa chính để chuyển hóa các phân tử này gồm có: quá trình glycolysis (chuyển đường D-glucose thành lactic acid), chu trình citric acid, chu trình pentose phosphate, quá trình gluconeogenesis (tạo glycogen từ các phân tử không phải carbonhydrate như protein, chất béo), tổng hợp và dự trữ glycogen và acid béo, các quá trình giáng hóa, tạo năng lượng và các hệ thống vận chuyển....

Glycolysis from [6-3 H]glucose and gluconeogenesis from [U-14 C]glycerol were examined in isolated hepatocytes from fasted rats. A 5 mMbolus of glycerol inhibited phosphory-lationof 40 mMglucoseby50%andglycolysis bymore than 60%, and caused cellular ATP depletion and glycerol 3-phosphate accumulation. Gluconeogenesis from 5 mM glycerol was una€ected by the presence of 40 mMglucose.

We used parameter scanning to emulate changes to the limitingrate for steps inafittedmodel of glucose-derepressed yeast glycolysis. Three flux-control regimes were observed, two of which were under the dominant control of hexose transport, in accordance with various experimental studies andothermodel predictions.

Erythrocytic stages of the malaria parasitePlasmodium fal-ciparumrely on glycolysis for their energy supply and it is unclear whether they obtain energy via mitochondrial res-piration albeit enzymes of the tricarboxylic acid (TCA) cycle appear to be expressed in these parasite stages. Isocitrate dehydrogenase (ICDH) is either an integral part of the mitochondrial TCA cycle or is involved in providing NADPH for reductive reactions in the cell.

Phylogenetic evidence is presented that primitively amito-chondriate eukaryotes containing the nucleus, cytoskele-ton, and endomembrane system may have never existed. Instead, the primary host for the mitochondrial progeni-tor may have been a chimeric prokaryote, created by fusion between an archaebacterium and a eubacterium, in which eubacterial energy metabolism (glycolysis and fermentation) was retained.

Methylglyoxal is the most important intracellular glycation agent, formed nonenzymatically from triose phosphates during glycolysis in eukaryotic cells. Methylglyoxal-derived advanced glycation end-products are involved in neurodegenerative disorders (Alzheimer’s, Parkinson’s and familial amy-loidotic polyneurophathy) and in the clinical complications of diabetes.

Diacylglycerol (DAG) andproteinkinase C(PKC) isoforms have been implicated in insulin signalling in muscle and fat cells.We evaluated the involvement ofDAGandPKCin the action of insulin in adult rat hepatocytes culturedwith dexa-methasone, but in the absence of serum, for 48 h. Our results show that although insulin stimulated glycolysis and glycogen synthesis, it had no effect on DAG mass or molecular species composition.

In Lactococcus lactisthe enzymes phosphofructokinase (PFK), pyruvate kinase (PK) and lactate dehydrogenase (LDH) are uniquely encoded in the las operon. We used metabolic control analysis to study the role of this organization. Earlier studies have shown that, at wild-type levels, LDH has no control over glycolysis and growth rate, but high negative control over formate production (C Jformate LDH ¼

Glucose-6-phosphate isomerase catalyzes the reversible aldose-ketose isomerization of D-glucose-6-phosphate to D-fructose-6-phosphate in glycolysis and gluconeogenesis, and in the recycling of hexose-6-phosphate in the pentose phosphate pathway. The unicellular protozoans,Trypan-osoma brucei, T. cruziandLeishmaniaspp., of the order Kinetoplastida are important human parasites responsible for African sleeping sickness, Chagas’ disease and leish-maniases, respectively. In these parasites, glycolysis is an important (and in some cases the only) metabolic pathway for ATP supply....
