Isozyme patterns of lactate and malate dehydrogenases were studied in tumors induced by SV40 and 7,12-dimethylbenz(a)anthracene and in established cultures of cells from these tumors. The expression of B polypeptide subunits of lactate dehydrogenase is suppressed similarly by both agents. This may
Previously, we reported a hypoxia-inducible factor (HIF)-1 inhibitor LW6 containing an (aryloxyacetylamino)benzoic acid moiety inhibits malate dehydrogenase 2 (MDH2) using a chemical biology approach. Structure-activity relationship studies on a series of (aryloxyacetylamino)benzoic acids identified
Increased glucose consumption is a hallmark of cancer cells. The increased consumption and subsequent metabolism of glucose during proliferation creates the need for a constant supply of NAD, a co-factor in glycolysis. Regeneration of the NAD required to support enhanced glycolysis has been
Chronic infection of woodchucks with woodchuck hepatitis virus (WHV) was associated with the development of hepatitis, foci of altered hepatocytes and hepatocellular adenomas and carcinomas. The cytomorphological and cytochemical analysis permitted the identification of three different types of
The aim of the present investigation was to evaluate the efficacy of Withania somnifera on tricarboxylic acid (TCA) cycle enzymes and electron transport chain in azoxymethane-induced experimental colon cancer in mice. Azoxymethane at the dose of 15 mg/kg body weight was induced intraperitoneally
A structure-activity relationship study of hypoxia inducible factor-1α inhibitor 3-aminobenzoic acid-based chemical probes, which were previously identified to bind to mitochondrial malate dehydrogenase 2, was performed to provide a better understanding of the pharmacological effects of LW6 and its
MCF-7 human breast cancer cells propagated in vitro were treated with adenosine derivatives added to the culture medium. The effects on cell proliferation, glycolysis, and glutaminolysis were investigated. Of all adenosine derivatives tested, AMP was the most efficient inhibitor of cell
The modulatory effect of Withania somnifera along with paclitaxel on tricarboxylic acid (TCA) cycle key enzymes and electron transport chain complexes were investigated against lung cancer induced by benzo(a)pyrene in Swiss albino mice. Decreased activities of TCA cycle key enzymes such as
The modulatory efficacy of capsaicin on lung mitochondrial enzyme system with reference to mitochondrial lipid peroxidation (LPO), antioxidants, key citric acid cycle enzymes and respiratory chain enzymes during benzo(a)pyrene (B(a)P) induced lung cancer in Swiss albino mice was studied. Elevations
Previous studies have shown cis-diamminedichloroplatinum(II) (Cis) an effective anti-tumour agent in man and animals. Evidence is presented here that formation of aquo complexes of this platinum derivative will significantly enhance its inhibitory properties with respect to two separate biochemical
BACKGROUND
Cancer cells have an abnormal energetic metabolism. One of the earliest discovered hallmarks of cancer had its roots in bioenergetics, as many tumours were found in the 1920s to exhibit a high glycolytic phenotype. An animal with cancer shows significant and progressive energy loss from
Betulin is a representative compound of Betula platyphylla, a tree species belonging to the Betulaceae family. In this investigation, we revealed that betulin showed anticancer activity on human lung cancer A549 cells by inducing apoptosis and changes in protein expression profiles were observed.
Beneficial effects of dehydroepiandrosterone (DHEA) supplement on age-associated chronic diseases such as cancer, cardiovascular disease, insulin resistance and diabetes, have been reported. However, its mechanism of action in hepatocellular carcinoma in vivo has not been investigated in detail. We
Asparate and alanine aminotransferase activity is approximately the same in different lobes of cerebral hemispheres of people with an uninjured central nervous system. The maximal activity of lactate, malate and succinate dehydrogenase is in the temporal lobes and thalami, the minimal one is in the
