The effect of interaction between Lipoprotein Lipase and ApoVLDL-II genes on fat and serum biochemical levels

Abstract

Body weight, abdominal fat weight and serum biochemical levels were determined from lean and fat chicken breeds at 12 weeks of age. Single nucleotide polymorphism (SNP) in apoVLDL-II and lipoprotein lipase genes was screened by PCR-SSCP and detected by direct sequencing. Lipoprotein lipase gene frequency was found to be significantly different (P < 0.01) in lean chicken whereas it was non-significantly different in fat chicken. SNP in apoVLDL-II and lipoprotein lipase genes significantly (P< 0.05) affected body weight and fat weight. Similarly their interaction significantly (P < 0.05) affected body weight and fat weight. However, no significant difference was observed in the percentage of abdominal fat. SNP in apoVLDL-II and lipoprotein lipase genes significantly (P < 0.05) affected total cholesterol and high density lipoprotein. More likely, the interaction of apoVLDL-II and lipoprotein lipase significantly affect total cholesterol, triglyceride, high density lipoprotein, very low density lipoprotein and low density lipoprotein.
