Teacher:In this task, you're given a paragraph from the research paper and your task is to generate a suitable title for the research paper based on the given paper. Under 100 words is a good title length.
Teacher: Now, understand the problem? Solve this instance: Transmissible gastroenteritis virus (TGEV) primarily replicates in intestinal epithelial cells and causes severe damage to host cells, resulting in diarrhea. Surface NHE3 serves as the key regulatory site controlling electroneutral Na + absorption. In this study, our results showed that the surface NHE3 content was significantly reduced following TGEV infection, whereas the total level of protein expression was not significantly changed, and NHE3 activity gradually decreased with prolonged infection time. We then inhibited SGLT1 expression by lentiviral interference and drug inhibition, respectively. Inhibition studies showed that the level of phosphorylation of the downstream key proteins, MAPKAPK-2 and EZRIN, in the SGLT1-mediated p38MAPK/AKt2 signaling pathway was significantly increased. The surface NHE3 expression was also significantly increased, and NHE3 activity was also significantly enhanced. These results demonstrate that a TGEV infection can inhibit NHE3 translocation and attenuates sodium-hydrogen exchange activity via the SGLT1-mediated p38MAPK/AKt2 signaling pathway, affecting cellular electrolyte absorption leading to diarrhea.
