The unique metabolic profile of cancer (aerobic glycolysis) might confer apoptosis resistance and be therapeutically targeted. Compared to normal cells, several human cancers have high mitochondrial membrane potential (DeltaPsim) and low expression of the K+ channel Kv1.5, both contributing to apoptosis resistance. Dichloroacetate (DCA) inhibits mitochondrial pyruvate dehydrogenase kinase (PDK)...
As an immune-inspired algorithm, the Dendritic Cell Algorithm (DCA), produces promising performance in the eld of anomaly detection. This paper presents the application of the DCA to a standard data set, the KDD 99 data set. The results of different implementation versions of the DCA, including antigen multiplier and moving time windows, are reported. The real-valued Negative Selection Algorith...
Infection by HIV-1 can effectively be suppressed by antiretroviral therapy (ART). However, the persistence of a small, latent virus reservoir impedes viral eradication. Thus, most infected individuals must be treated with ART for life. While efforts to find a sterilizing cure that eradicates the virus are ongoing, an alternative approach deemed a functional cure has remained less explored. A fu...
HeLa and PANC-1 cells were exposed to conflicting signals promoting anaerobic or aerobic energy-generating processes and their viability, cell numbers and the ability of HeLa cells to form colonies were assessed. Under conventional aerobic cell culture with 5% CO(2), dichloroacetate (DCA), an inhibitor of the enzyme pyruvate dehydrogense kinase with subsequent stimulation of pyruvate dehydrogen...
BACKGROUND The hydrophilic bile salt ursodeoxycholate (UDCA) inhibits injury by hydrophobic bile acids and is used to treat cholestatic liver diseases. Interestingly, hepatocyte cell death from bile acid-induced toxicity occurs more frequently from apoptosis than from necrosis. However, both processes appear to involve the mitochondrial membrane permeability transition (MPT). In this study, we ...
Aconitine-containing agent enhances antitumor activity of dichloroacetate against Ehrlich carcinoma.
UNLABELLED Significant variability of anticancer efficacy of dichloroacetate (DCA) stimulated an active search for the agents capable to enhance it antitumor action. Therefore, the aim of this work is the study of capability of aconitine-containing antiangiogenic agent BC1 to enhance anticancer activity of DCA against Ehrlich carcinoma. MATERIALS AND METHODS DCA (total dose was 1.3 g/kg of b....
UNLABELLED It is known that glycolysis contributes to the survival of tumor cells by providing them with energetic and plastic substrates. Dichloroacetate (DCA) as inhibitor of kinase pyruvate dehydrogenase shifts balance of energy metabolism of tumor cells from aerobic glycolysis towards oxidative phosphorylation. The aim of the study was to investigate cytostatic/cytotoxic effect of DCA on gl...
Elevated levels of bile acids have been implicated in the abnormal morphogenesis of the colonic epithelium thus contributing to colorectal cancer (CRC). Alternatively sodium butyrate (NaB) produced by anaerobic fermentation of dietary fibre is regarded as being protective against colon cancer. Bile acids such as deoxycholic acid (DCA) are thought to mediate some of their actions by differential...
