The effects of taurine on serum cholesterol levels and hepatic cholesterol 7alpha-hydroxylase activity (CYP7A1) were studied in rats fed cholestyramine or high amounts of sodium cholate in order to alter the intestinal pool of bile acids. Rats were fed a diet supplemented with 1% cholesterol and 0.25% sodium cholate (high cholesterol, control; C), and C supplemented with 4% cholestyramine (CH) ...

INTRODUCTION The present study was designed to investigate whether taurine mitigates fructose-induced oxidative stress in rat tissues such as heart and kidney. METHODS Male Wistar rats of body weight 170-190 g were divided into four groups containing six rats each. Control animals received the control diet containing starch while fructose-fed animals received a fructose-enriched diet (greater...

Hypoxia-induced apoptosis of retinal ganglion cells (RGCs) is the major cause of progressive vision loss in numerous retinal diseases, including glaucoma and diabetic retinopathy. Taurine is a naturally occurring free amino acid that has been shown to have neurotrophic and neuroprotective properties in the retina. We investigated the specific potential for taurine to be protective for immortali...

Potassium bromate (KBrO3) is widely used as a food additive and is a major water disinfection by-product. It induces multiple organ toxicity in humans and experimental animals and is a probable human carcinogen. The present study reports the protective effect of dietary antioxidant taurine on KBrO3-induced damage to the rat intestine. Animals were randomly divided into four groups: control, KBr...

BACKGROUND It is known that large dogs who are fed lamb and rice diets are at increased risk to develop taurine-deficiency-induced dilated cardiomyopathy. Since dogs obligatorily conjugate bile acids (BA) with taurine, we determined whether rice bran (RB) or other fibers (cellulose; CL, beet pulp; BP) would affect BA excretion and/or the taurine status of dogs. RESULTS Eighteen medium/large m...

Maternal obesity is associated with obesity and metabolic disorders in offspring. However, intervention strategies to reverse or ameliorate the effects of maternal obesity on offspring health are limited. Following maternal undernutrition, taurine supplementation can improve outcomes in offspring, possibly via effects on glucose homeostasis and insulin secretion. The effects of taurine in media...

Jiats and rabbits were fed a hypereholesteremic diet until elevated serum cholesterol levels were observed in all animals. The animals were then divided into groups, one group remaining on the original diet and the others receiving the same hypercholesteremie diet fortified with either taurine, glycine, or /8-sitosterols. In the rat, 4 per cent taurine in the diet significantly decreased the se...

Maintaining cell volume is critical for cellular function yet shift in cell volume is a prerequisite for mitosis and apoptosis. The ubiquitously and evolutionary conserved serine/threonine kinase CK2 promotes cell survival and suppresses apoptosis. The present review describes how mammalian cells regulate the cellular content of the major cellular organic osmolyte, taurine with emphasis on CK2 ...

Uptake of taurine in human placental brush-border membrane vesicles was greatly stimulated in the presence of an inwardly-directed Na+ + Cl- -gradient and uphill transport of taurine could be demonstrated under these conditions. Na+ as well as Cl- were obligatory for this uptake and both ion gradients could energize the uphill transport. This Na+ + Cl- -gradient-dependent taurine uptake was sti...

In agreement with previous results (Awapara, 1956), we noted that the taurine level in the liver of the adult female rat is higher than in the adult male rat: 9.44 and 2.08, respectively, expressed as a concentration (mumoles/g of liver). Furthermore, we observed a significant decrease of the taurine level (expressed similarly) in the liver of the lactating rat: 1.84 twenty-one days after the b...
