Última Cholesterol changes the fatty acid composition of rat enterocytes BJMBR Gazzola,J.; Martins,E.F.; Miyasaka,C.K.; Palanch,A.C.; Vecchia,M.G.; Curi,R.. The effect of free cholesterol on the fatty acid composition and growth of rat fetal enterocytes was investigated in the absence and presence of 10% (v/v) fetal calf serum. Cholesterol caused a significant reduction of cell number after 6 and 12 h in culture. The fatty acid composition of enterocytes cultured in the presence of serum was also changed by the presence of 20 µM cholesterol. The fatty acid profile was determined by HPLC using fluorescence detection (325 nm excitation and 395 nm emission). Cholesterol (20 µM) increased the proportion (given in percentage of the total fatty acids) of the following fatty acids in cultured cells: lauric (by 42%), oleic (by 34%), linoleic (by 44%) and gamma-linolenic (by 20%) acids and reduced the proportion of...

Ano: 2003 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-879X2003000100019 Cholesterol induces fetal rat enterocyte death in culture BJMBR Gazzola,J.; Silva,É.P.P.; Kanunfre,C.C.; Verlengia,R.; Vecchia,M.G.; Curi,R.. The effect of cholesterol on fetal rat enterocytes and IEC-6 cells (line originated from normal rat small intestine) was examined. Both cells were cultured in the presence of 20 to 80 µM cholesterol for up to 72 h. Apoptosis was determined by flow cytometric analysis and fluorescence microscopy. The expression of HMG-CoA reductase and peroxisome proliferator-activated receptor gamma (PPARgamma) was measured by RT-PCR. The addition of 20 µM cholesterol reduced enterocyte proliferation as early as 6 h of culture. Reduction of enterocyte proliferation by 28 and 41% was observed after 24 h of culture in the presence and absence of 10% fetal calf serum, respectively, with the effect lasting up to 72 h. Treatment of IEC-6 cells with cholesterol for 24 h raised... Tipo: Info:eu-repo/semantics/article Palavras-chave: Fetal enterocytes; Cholesterol; Intestine; IEC-6 cells; HMG-CoA; PPARgamma. Ano: 2004 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-879X2004000700019 Wheat bran- but not oat bran-enriched diets increase the mucosal height of the cecum and colon of newly weaned and aged rats BJMBR Cavaglieri-Felippe,C.R.; Polacow,M.L.O.; Campos,M.R.; Vecchia,M.G.; Curi,R.. The effect of diets enriched with oat or wheat bran (prepared by the addition of 300 g of each fiber to 1000 g of the regular diet), given for 8 weeks, on the mucosal height of the colon and cecum was investigated. Newly weaned (21 days old) and aged (12 months old) male Wistar rats were used in this study. As compared to controls, diets enriched with wheat bran provoked a significant increase in the mucosal height, whereas oat bran did not cause any effect. In newly weaned rats (21 days old), wheat bran increased the mucosal height (µm) in the cecum by 20% (mean ± SEM for 8 rats; 169.1 ± 5.2 and 202.9 ± 8.0 for control and wheat bran, respectively) and in the colon (218.8 ± 7.2 and 264.5 ± 18.8 for control and wheat bran, respectively). A similar effect... Tipo: Info:eu-repo/semantics/article Palavras-chave: Oat bran; Wheat bran; Colon; Cecum; Mucosa; Ageing.
