摘要： Yangtze sturgeon (Acipenser dabryanus) is a species endemic to Yangtze River drainage in China and is listed as a critically endangered species on the IUCN Red List. In the present study, cholecystokinin (CCK), one of the most important neuroregulatory digestive genes, and its receptor (CCKr) were identified from the full-length tran-scriptome analysis of A. dabryanus. The deduced amino acid sequences of CCK and CCKr from A. dabryanus showed structural features common to those in other vertebrates. Gene expression profile analysis showed that CCK and CCKr were universally expressed in different tissues, and both had the highest expression in the brain. Starvation and refeeding significantly regulated the expression levels of CCK and CCKr in the brain, suggesting that CCK and CCKr were involved in feed intake regulation in A. dabryanus as in mammals. In addition, the expression levels of CCK and CCKr under different feeding frequencies were studied. Compared with the control group (fed two times a day), the expression levels of CCK and CCKr in the intestine and brain did not change significantly in the other groups after 8 weeks of rearing, indicating that the feeding frequency might not in-fluence the appetite of A. dabryanus. The present work provides a basis for further investigation into the regu-lation of feeding in A. dabryanus.
