an increased luminal pH results in decreased intestinal dipeptide transport in freshwater-acclimated fish | Fundulus heteroclitus |

an increased luminal pH results in decreased intestinal dipeptide transport in freshwater-acclimated fish but suggests an increased dipeptide transport in seawater-acclimated fish | Fundulus heteroclitus |
Expression
| Organism | Comment | Expression |
|---|---|---|
| Fundulus heteroclitus | short-term fasting results in up-regulation of PepT1 mRNA levels, while prolonged fasting results in down-regulation. The resumption of feeding results in up-regulation of PepT1 above pre-fasted levels | additional information |
