There is growing evidence that metabolic alterations play an important role in cancer development and progression. The metabolism of cancer cells is reprogrammed in order to support their rapid proliferation. Elevated fatty acid synthesis is one of the most important aberrations of cancer cell metabolism. An enhancement of fatty acids synthesis is required(More)
BACKGROUND A high level of circulating PCSK9 binds to the LDL receptor, reduces its cell's surface density and leads to hypercholesterolemia. The aim of this study was to examine the circulating PCSK9 level in patients with kidney disease. METHODS Out of the patients treated in our Departments we selected: (a) 44 patients with CKD stage 3 and 4 (b) 29(More)
Monitoring level of the metabolites of the coenzyme NAD such as nicotinamide and its oxidized and methylated derivatives is important due to therapeutic applications of these compounds and monitoring of oxidative stress. We evaluated feasibility of using HPLC with electrospray ion-trap mass detection for single run separation and quantitation of all the NAD(More)
Fibrate derivatives are commonly used to treat hyperlipidaemia; however, the mechanism of the antilipidaemic action of these drugs is still unknown. The effect of clofibrate (fibrate derivative) administration for 14 days on lipogenesis and on malic enzyme (EC 1.1.1.40) and fatty acid synthase (EC 2.3.1.85) gene expression in brown and white adipose tissues(More)
The changes in adenine nucleotide concentration induced by acetate were investigated in rat liver in situ and in isolated rat hepatocytes. Adenosine monophosphate (AMP) concentration increased approximately threefold within 15 minutes after intraperitoneal injection of sodium acetate. A small but significant decrease in adenosine triphosphate (ATP)(More)
Progesterone affects lipid metabolism in adipose tissue and influences fat distribution in human. The aim of the study was to analyze the effect of progesterone on rat body and fat mass and on expression of genes encoding adipokines involved in the regulation of energy homeostasis. The results presented here indicate that progesterone administration to(More)
Common molecular changes in cancer cells are high carbon flux through the glycolytic pathway and overexpression of fatty acid synthase, a key lipogenic enzyme. Since glycerol 3-phosphate dehydrogenase creates a link between carbohydrates and the lipid metabolism, we have investigated the activity of glycerol 3-phosphate dehydrogenase and various lipogenic(More)
Successful treatment of obesity and related diseases by chronic food restriction requires the understanding of the effect of such nutritional therapy on the expression of genes which have been implicated to be involved in some diseases associated with obesity. The purpose of this study was to examine the effect of chronic food restriction and chronic food(More)
Mechanisms involved in the multihormonal regulation of fatty acid synthase have been investigated by comparing levels of its mRNA with rates of enzyme synthesis in chick embryo hepatocytes in culture. Triiodothyronine or insulin caused about a 2.5-fold increase in the relative rate of synthesis of fatty acid synthase. Together, these hormones were(More)
