摘要:
分离、克隆梭鱼脂肪酸合成酶(fatty acid synthase,简称FAS)基因的部分cDNA片段(GenBank登录号为KJ848474),共920 bp,编码303个氨基酸,序列分析表明梭鱼FAS基因与其他物种的同源性为74%~95%,其中与军曹鱼、斑马拟丽鱼相似性达95%。FAS基因mRNA在梭鱼鱼皮、肌肉、肝脏、心脏、脾脏、肾脏、胃、肠、腹腔脂肪、脑和鳃组织中表达丰度差异显著(P<0.05),脑中含量最高,其次是肝脏和腹腔脂肪组织,肌肉中表达量最低,其余7种组织中的表达量均显著低于脑和肝脏(P<0.05)。此外,还研究了饲料脂肪水平对梭鱼FAS活性和mRNA表达的影响,平均质量为(9.5±0.3)g的梭鱼幼鱼投喂6种不同脂肪含量的等氮等能饲料(脂肪水平分别为2.04%、4.83%、747%、979%、12.01%、14.59%),饲养60 d,试验结束后测定各组梭鱼肝脏中FAS的生物活性及肝脏、腹腔脂肪、肌肉中FAS mRNA的表达丰度。结果表明,随着饲料脂肪水平的升高,肝脏中FAS活性呈降低趋势,14.59%组的活性显著低于2.04%、4.85%组(P<0.05);肝脏中FAS的mRNA表达量显著下降(P<0.05);肌肉和腹腔脂肪中FAS的mRNA表达量呈下降趋势,但各组之间差异不显著(P>0.05)。
