The aim of this study was to investigate acetylcholinesterase (AChE) in total blood and liver tissue; butyrylcholinesterase (BChE) in serum and liver tissue; adenosine deaminase (ADA) in serum and liver tissue; and pyruvate kinase (PK) in liver tissue of rats experimentally infected by Fasciola
OBJECTIVE Pyruvate kinase type M2 (TuM2-PK) and thymidine kinase 1 (TK1) are the key enzymes involved in tumor cells metabolism and proliferation. We explored the association of their preoperative circulating levels with disease recurrence in patients with renal cell carcinoma (RCC). METHODS We
OBJECTIVE To compare the response of chondrocytes and cartilage matrix to injurious mechanical compression and treatment with interleukin-1beta (IL-1beta) and tumor necrosis factor alpha (TNFalpha), by characterizing proteins lost to the medium from cartilage explant culture. METHODS Cartilage

Activities of hexokinase, phosphofructokinase and pyruvate kinase were studied in rat heart after emotional-painful stress and development of myocardium necrosis. The stress caused an activation of hexokinase and phosphofructokinase within 2 and 7 days, activity of pyruvate kinase was not altered.

The effects of an intravenous administration of a single dose (100 micrograms/kg bw) of tumour necrosis factor-alpha (TNF, cachectin) on in vivo glucose oxidation and on several enzymatic activities related with glucose metabolism both in rat liver and skeletal muscle were studied. The treatment

Bcl-2 inhibits tumor necrosis factor-alpha-mediated increase of glycolytic enzyme activities and enhances pyruvate carboxylase activity.

To understand the effects of bcl-2 on glucose metabolism and tumor necrosis factor-alpha (TNF-alpha) mediated cytotoxicity, the activities of glycolytic enzymes (hexokinase, 6-phosphofructo-1-kinase, and pyruvate kinase), lactate dehydrogenase, pyruvate carboxylase, and phosphoenolpyruvate

Bcl2-low-expressing MCF7 cells undergo necrosis rather than apoptosis upon staurosporine treatment.

We present a ribozyme-based strategy for studying the effects of Bcl2 down-regulation. The anti-bcl2 hammerhead ribozyme Rz-bcl2 was stably transfected into MCF7 cancer cells and the cleavage of Bcl2 mRNA was demonstrated using a new assay for cleavage product detection, while Western blot analysis

Intravenous administration of a single dose (100 micrograms/kg bw) of recombinant tumour necrosis factor-alpha (TNF, cachectin) to rats increased the rate of in vitro fatty acid synthesis in interscapular brown adipose tissue (IBAT) from both glucose and alanine, without changes in the oxidation of
Inflammation is an energy-intensive process, and caloric restriction (CR) could provide anti-inflammatory benefits. CR mimetics (CRM), such as the glycolytic inhibitor 2-deoxyglucose (2-DG), mimic the beneficial effects of CR without inducing CR-related physiologic disturbance. This study

Pyruvate kinase M2 regulates apoptosis of intestinal epithelial cells in Crohn's disease.

BACKGROUND Pyruvate kinase M2 (PKM2), a key glycolytic enzyme, is involved in multiple cellular processes including apoptosis. Recently increased fecal PKM2 has been found in Crohn's disease (CD), but little is known regarding its function in the pathophysiology of the disease. OBJECTIVE The

Cyclosporine A inhibits breast cancer cell growth by downregulating the expression of pyruvate kinase subtype M2.

The high proliferative rate of tumor cells leads to metabolic needs distinct from those of their normal counterparts. An embryonic- and tumor-specific isoform of the enzyme pyruvate kinase M2 (PKM2) is overexpressed in cancer cells to increase the use of glycolytic intermediates for macromolecular

Regulation of pyruvate kinase isozyme M2 is mediated by the ubiquitin-specific protease 20.

The existence of a liver stem cell population has only gained credence recently, following the results of animal experiments. These cells are thought to reside in the terminal bile ductules (canals of Hering). Hepatocyte division is responsible for liver regeneration after most causes of injury.
