Gene Expression of Glycolysis Enzymes in MCF-7 Breast Cancer Cells Exposed to Warburg Effect and Hypoxia.

Hypoxia can cause significant changes in the glucose metabolism of cancer cells that prefer aerobic glycolysis for energy production instead of the conventional oxidative phosphorylation mechanism. In this study, breast cancer cells (MCF-7) were exposed to glucose (0-5.5-15-55 mM), during specific incubation periods (3, 6, 12, or 24 hours) under normoxic and hypoxic conditions.

Anti- inflammatory effect of boric acid on cytokines in ovariectomy-induced rats.

The increase in the rate of inflammation in the post-menopause period also leads to a significant increase in the use of anti-inflammatory agents. This study aimed to investigate the effect of BA supplementation on pro-and anti-inflammatory cytokines in ovariectomy (OVX) induced rats. A total of 48 nonpregnant female Wistar albino rats (80-100 g) were used in the experiment.

Assessment of pollution with biomarkers in fish culture.

Biotransformation enzymes are stimulated or inhibited depending on the exposure to xenobiotics and widely used as a biomarker. In this study, EROD activity, GST activity, reduced GSH amount, amount of lipid peroxidation product MDA as oxidative stress parameter, and ACHE inhibition as a neuromuscular parameter were measured in liver and muscle tissues of rainbow trout (Oncorhynchus mykiss) produced in aquaculture of Kemer Dam and in concrete ponds located in Fethiye. Samples were collected in January and July from fish farming in net cages in Kemer Dam and concrete cages in Fethiye in order to evaluate seasonal changes.

Investigation of glucose catabolism in hypoxic Mcf 7 breast cancer culture.

Hypoxia plays an important role in tumor phenotype and progression and alters glycolysis, with changes in signaling pathways that develop in response to hypoxia. In this study, the effects of oxygen (normoxia/hypoxia) and of glucose levels on the glucose metabolism was investigated in MCF-7 cancer cells. Under either normoxia or hypoxia conditions, the cells were exposed to glucose at different concentrations (0, 5.

Determination of DNA damage in experimental liver intoxication and role of N-acetyl cysteine.

The present study aimed at detecting DNA damage and fragmentation as well as histone acetylation depending on oxidative stress caused by CCl4 intoxication. Also, the protective role of N-acetyl cysteine, a precursor for GSH, in DNA damage is investigated. Sixty rats were used in this study.

Acute phase protein levels in pregnancy and oestrus cycle in bitches.

The purpose of this study was to evaluate the acute phase protein (serum amyloid A, C-reactive protein, haptoglobin, ceruloplasmin and fibrinogen) profiles in pregnant dogs as well as bitches at various stages of the estrus cycle and to verify possible relationship(s) among the APPs profile and hormonal status. A total of 60 bitches of various breeds were enrolled. The animals were divided into six groups.

Serum and hair levels of zinc and other elements in dogs with visceral leishmaniasis.

The aim of this study was to determine the zinc, iron, copper, calcium, phosphorus, and magnesium levels in blood serum and zinc and copper levels in hair of dogs with canine visceral leishmaniasis. The serum zinc and iron levels were found to be significantly lower in diseased dogs than those of healthy controls. Serum copper levels were significantly higher, whereas no significant differences were observed for calcium, phosphorus, and magnesium.
