PG - 321-334 LID - 10.1017/S000711452100101X [doi] AB - A12-week experiment was conducted to evaluate the influences of thiamine ongrowth performance, and intestinal mitochondrial biogenesis and function of Megalobramaamblycephala fed a high-carbohydrate (HC) diet. Fish (24.73 (sem 0.45) g) were randomly assigned to one of four diets: two carbohydrate (CHO) levels (30 and 45 %) and two thiamine levels (0 and 1.5 mg/kg). HC diets significantly decreased DGC, GRMBW, FIMBW, intestinal activities of amylase, lipase, Na+, K+-ATPase, CK, complexes I, III and IV, intestinal ML, number of mitochondrial per field, DeltaPsim, the P-AMPK: T-AMPK ratio, PGC-1beta protein expression as well as the transcriptions of AMPKalpha1, AMPKalpha2, PGC-1beta, mitochondrial transcription factor A, Opa-1, ND-1 and COX-1 and 2, while the opposite was true for ATP, AMP and reactive oxygen species, and the transcriptions of dynamin-related protein-1, fission-1 and mitochondrial fission factor. Dietarythiamine concentrations significantly increased DGC, GRMBW, intestinal activities of amylase, Na+, K+-ATPase, CK, complexes I and IV, intestinal ML, number of mitochondrial per field, DeltaPsim, the P-AMPK:T-AMPK ratio, PGC-1beta protein expression as well as the transcriptions of AMPKalpha1, AMPKalpha2, PGC-1beta, Opa-1, ND-1, COX-1 and 2, SGLT-1 and GLUT-2. Furthermore, a significant interaction between dietary CHO and thiamine was observed in DGC, GRMBW, intestinal activities of amylase, CK, complexes I and IV, DeltaPsim, the AMP:ATP ratio, the P-AMPK:T-AMPK ratio, PGC-1beta protein expression as well as the transcriptions of AMPKalpha1, AMPKalpha2, PGC-1beta, Opa-1, COX-1 and 2, SGLT-1 and GLUT-2. Overall, thiamine supplementation improved growth performance, and intestinal mitochondrial biogenesis and function of M. amblycephala fed HC diets.
