چکیده انگلیسی
Uptake of energy into cells and its allocation to individual cellular compartments by transporters are essential for tissue homeostasis. The present study gives an analysis of MCT1 expression and its cellular occurrence in the porcine intestine. Tissue portions from duodenum, jejunum, ileum, colon ascendens, colon transversum and colon descendens were collected and prepared for immunohistochemistry, Western blot and real time RT-PCR. A 169Â bp porcine MCT1 cDNA fragment was amplified and published. MCT1 mRNA expression in the large intestine was 20 fold higher compared to the small intestine. Western blot detected a single protein band of 41Â kDa at a much higher amount of MCT1 protein in the large intestine vs. the small intestine. MCT1 protein was detected in mitochondrial fractions of the large but not the small intestine. Immunohistochemistry in the small intestine showed that immune cells in the lamina propria and in the lymphoid follicles primarily expressed MCT1 while in the colon epithelial cells were the main source of MCT1. In summary, cellular expression of MCT1 differs between epithelial cells in the colon and small intestine. A possible role of MCT1 for uptake of butyrate into immune cells and the overall role of MCT1 for intestinal immune cell function remains elusive.
