The "Warburg effect," also termed aerobic glycolysis, describes the increased reliance of cancer cells on glycolysis for ATP production, even in the presence of oxygen. Consequently, there is continued interest in inhibitors of glycolysis as cancer therapeutics. One example is dichloroacetate (DCA), a pyruvate mimetic that stimulates oxidative phosphorylation through inhibition of pyruvate dehy...

The decrease in plasma lactate during dichloroacetate (DCA) treatment is attributed to stimulation of lactate oxidation. To determine whether DCA also inhibits lactate production, we measured glucose metabolism in muscles of fed and fasted rats incubated with DCA and insulin. DCA increased glucose-6-phosphate, an allosteric modifier of glycogen synthase, approximately 50% and increased muscle g...

Given a distributed coordination algorithm (DCA) for agents coupled by a network, which can be characterized by a stochastic matrix, we say that the DCA can be asynchronously implemented if the consensus property is preserved when the agents are activated to update their states according to their own clocks. This paper focuses on two central problems in asynchronous implementation of DCA: which...

[Ru(bpy)(3)](2+) (bpy = 2,2'-bipyridine) ions were entrapped into the cavities of two-dimensional anionic sheet-like coordination polymeric networks of [M(dca)(3)](-) (dca = dicyanamide; M = Mn(II) and Fe(II)). The prepared compounds, {[Ru(bpy)(3)][Mn(dca)(3)](2)}(n) (1) and {[Ru(bpy)(3)][Fe(dca)(3)](2)}(n) (2), were structurally characterized by X-ray single crystal analysis. The spectroscopic...

Two new dicyanamide bridged complexes [Mn(μ1,5-dca)2(salicyh)2]n (1) and {[Ni(μ1,5-dca)(TTA)](ClO4)}n (2) (dca = dicyanamide, ; salicyh = salicylic hydrazide; TTA = triethylenetetramine) have been synthesised and structurally characterised. Both the compounds 1 and 2 consist in 1-D coordination polymers. In 1 the manganese atoms are doubly bridged by μ1,5-dca ligands, whereas in 2 the nickel at...

BACKGROUND Bcl-2 protects cells from apoptosis and provides a survival advantage to cells over-expressing this oncogene. In addition, over expression of Bcl-2 renders cell resistant to radiation therapy. Recently, dichloroacetate (DCA) was proven to potentiate the apoptotic machinery by interacting with Bcl-2. In this study, we investigated whether treating human prostate cancer cells with DCA ...

Previously, we have demonstrated that deoxycholic acid (DCA)-induced signaling of extracellular signal-regulated kinases 1 and 2 (ERK1/2) in primary hepatocytes is a protective response. In the present study, we examined the roles of the ERK and c-Jun NH(2)-terminal kinase (JNK) pathways, and downstream transcription factors, in the survival response of hepatocytes. DCA caused activation of the...

T HE EFFECT of desoxycorticosterone acetate (DCA) on potassium (K) metabolism has been investigated extensively in man, dog and rat; the characteristic response consists of kaluresis, hypokalemia and metabolic alkalosis. Dependence of these alterations in electrolyte metabolism on an adequate intake of sodium (Na) was recognized by Seldin, Welt and Cort (I). They reported that patients fed a lo...

Dynamic channel allocation (DCA) techniques have been discussed in detail in the excellent overview paper of Katzela and Naghshineh[1]. Zander [2] investigated the limitations of radio resource management in future wireless networks, while Peha et al [3] discussed the practical problems that may be encountered in designing a DCA based mobile radio system. In dynamic channel allocation all suffi...

Dichloroacetate (DCA) is a toxicant by-product from the chlorination disinfection process for municipal water. The levels would not affect people with normal renal and liver function. However, people with impaired renal or liver function may have an increased susceptibility to DCA toxicity as those are the organs affected by DCA. People (and rodents) with polycystic kidney disease (PKD) are pol...
