Abstract:Spermatophore regeneration is an important biological process in Litopenaeus vannamei. In this study, changes of biochemical components contents during spermatophore regeneration showed that in hemolymph, the glucose content significantly increased from day 2 to day 8 and then decreased from day 10 to day 12; triglyceride (TG) and total cholesterol (TC) contents were relatively stable. In the hepatopancreas, glucose, and TG contents significantly decreased during regeneration; TC contents significantly increased at day 4 and then decreased. In the testes, glucose content significantly increased while TC content significantly decreased during whole stage; TG content at day 4 was highest. In terminal ampoule, changes of glucose and TC contents were similar, the contents at day 4 were highest; TG content at day 6 was significantly lower than day 2. During spermatophore regeneration, expression level of pyruvate kinase (PK) was significantly higher during day 2 to day 4 than at other times, and expression levels of three lipogenesis-related genes diacylglycerol O-acyltransferase homolog 1 (DGAT1), sterol regulatory element-binding protein 1 (SREBP1) and sterol O-acyltransferase 2 (SOAT2) were significantly higher during day 2 to day 8 than at other times. The results indicated that the hepatopancreas could be the energy source that provides glucose and TG; glucose, TG, and TC play important roles in spermatophore regeneration
