Metallothioneins (MTs) are low-molecular-weight metal-binding proteins potentially involved in the detoxification of heavy metals, protection against oxidative stress, and other biological processes. This study examined progesterone’s influence on Mt gene expression in rat adipose tissue. Wistar rats (females and males) received 100 mg of progester...

Background 5-Fluorouracil (5-FU) is a cornerstone in treatment of colorectal cancer (CRC) and is usually combined with leucovorin (LV) to enhance the antitumour effect by increase thymidylate synthase (TS) inhibition, the key target enzyme for 5-FU. Arfolitixorin (Arfo) is an active form of the reduced folate, [6 R]-5,10-methylenetetrahydrofolate (...

Lipid metabolism in various adipose tissue depots can differ vastly. This also applies to lipogenesis, the process of synthesizing fatty acids from acetyl-CoA. This study compared the expression of some lipogenic enzymes: fatty acid synthase (FASN), ATP-citrate lyase (ACLY), and malic enzyme 1 (ME1) in different regions of the posterior subcutaneou...

Systemic sclerosis is a rare autoimmune condition leading to incurable complications. Therefore fast and precise diagnosis is crucial to prevent patient death and to maintain quality of life. Unfortunately, currently known biomarkers do not meet this need. To address this problem researchers use diverse approaches to elucidate the underlying aberra...

Fatty acid metabolism, including β-oxidation (βOX), plays an important role in human physiology and pathology. βOX is an essential process in the energy metabolism of most human cells. Moreover, βOX is also the source of acetyl-CoA, the substrate for (a) ketone bodies synthesis, (b) cholesterol synthesis, (c) phase II detoxication, (d) protein acet...

This review highlights the complex role of fatty acid β-oxidation in brain metabolism. It demonstrates the fundamental importance of fatty acid degradation as a fuel in energy balance and as an essential component in lipid homeostasis, brain aging, and neurodegenerative disorders.

Purpose Amino acids (AAs) play important physiological roles in living cells. Some amino acid changes in blood are specific for autoimmune disorders, and some are specific for thyroid cancer. The aims of this study were to profile AA metabolites in the serum of patients with papillary thyroid carcinoma (PTC0) without Hashimoto’s thyroiditis (HT) an...

Background: Systemic sclerosis (SSc) is an autoimmune disease with an elusive etiology and poor prognosis. Due to its diverse clinical presentation, a personalized approach is obligatory and needs to be based on a comprehensive biomarker panel. Therefore, particular metabolomic studies are necessary. Lipidomics addressed these issues and found dist...

(1) Background: Hyperbaric oxygen therapy (HBOT) uses 100% oxygen delivered at 1.5–3 times the atmospheric pressure in a specialised chamber to achieve supraphysiological oxygen tension in blood and tissues. Besides its target, HBOT may affect inflammation, endothelial function or angiogenesis. This study analysed the effect of HBOT on blood concen...

The importance of coenzyme A (CoA) as a carrier of acyl residues in cell metabolism is well understood. Coenzyme A participates in more than 100 different catabolic and anabolic reactions, including those involved in the metabolism of lipids, carbohydrates, proteins, ethanol, bile acids, and xenobiotics. However, much less is known about the import...

Background Cumulating evidence underlines the role of adipose tissue metallothionein (MT) in the development of obesity and type 2 diabetes. Fasting/refeeding was shown to affect MT gene expression in the rodent liver. The influence of nutritional status on MT gene expression in white adipose tissue (WAT) is inconclusive. The aim of this study was...

Recent findings suggest that inhibition of AMP-deaminase (AMPD) could be effective therapeutic strategy in heart disease associated with cardiac ischemia. To establish experimental model to study protective mechanisms of AMPD inhibition we developed conditional, cardiac specific knock-outs in Cre recombinase system. AMPD3 floxed mice were crossed w...

Nucleotide metabolism and signalling is directly linked to myocardial function. Therefore analysis how diversity of genes coding nucleotide metabolism related proteins affects clinical progress of heart disease could provide valuable information for development of new treatments. Several studies identified that polymorphism of AMP deaminase 1 gene...

Chemerin is an adipokine that regulates adipocyte development and metabolism as well as inflammatory and immune function of some cells. Although chemerin may be linked to obesity and related diseases, little is known about the nutritional regulation of chemerin gene expression. We investigated the effect of prolonged food restriction, a common appr...

It is generally accepted that the location of body fat deposits may play an important role in the risk of developing some endocrine and metabolic diseases. We have studied the effect of food restriction and food restriction/refeeding, often practiced by individuals trying to lose body weight, on the expression of genes which are associated with obe...

Corticosterone — product of 11-β-hydroxysteroid dehydrogenase type I (11βHSD1) stimulates adipocytes differentiation and activates lipogenic enzymes gene expression in white adipose tissue (WAT) of rats. The aim of the study was to examine the effect of chronic food restriction, often practised by obese individuals trying to lose body mass, on: a)...

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 chron...

Several lines of evidence suggest that malonyl-CoA in the hypothalamus plays an important role in monitoring and modulating body energy balance. In fasted state the level of malonyl-CoA concentration significantly decreases. Simultaneously, orexigenic neuropeptides (NPY - neuropeptide Y, AgRP - agouti-related peptide) genes are expressed at high le...

Beneficial effects of food restriction as well as elevated circulating adiponectin concentration on the cardiovascular system, lipid metabolism and non-insulin dependent diabetes have been reported. The present article indicates that the reduction in rat body and adipose tissue weight after long-term (1 month) food restriction (either 75% or 50% of...

Microsatellite alterations are a common feature of neoplastic cells. Our study aimed to compare the profile of microsatellite DNA alterations in tumor tissue and urine sediment at 12 selected microsatellite loci in transitional cell carcinoma of the bladder, and to determine which of the 12 markers or combination of markers has potential for the no...

Assuming that a high flux of carbohydrate is strictly connected with lipid synthesis in neoplastic cells, one can hypothesize that the activity of citrate synthase, which plays an important role in glucose to lipid conversion, is enhanced in pancreatic cancer. The aim of the present study was to verify this hypothesis. The activity of citrate synth...

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 li...
