Relationship between apolipoprotein A5gene-1131T＞C and fat content on adult Tibetans in Tibetarea and Han nationality population in Liaoning province / 安徽医科大学学报

ABSTRACT

Objective To explore the gene frequency of apolipoprotein A5(APOA5)-1131T>C single nucleotide polymorphisms and its relationship with the fat contents of adult Tibetans in Tibet and Han nationality population in Liaoning province.Methods In 100 Tibetan nationality(the study group) and 100 Han nationality individuals(the control group), the polymorphism of apoa5-1131T>C genotypes was detected by polymerase chain reaction-restricted fragments length polymorphism(PCR-RFLP), and fat contents were got by using bioelectrical impedance measurement.Results Results of fat contents of body, trunk and limbs(left upper limbs, left lower limbs, right upper limbs, right lower limbs and total limbs) were respectively below① There was significant difference between male TC+CC genotype and TT genotype of Tibetan nationality.There was significant difference between male TT genotype of Tibetan nationality and of Han nationality.② There was significant difference between female TT genetype of Tibetan nationality and of Han nationality except result of the body fat contents.③ There was significant difference between the trunk and total limbs fat contents in male TT genotype, and male TC+CC genotype of Tibetan nationality and of Han nationality, and female TT genotype of Tibetan nationality.Conclusion APOA5 gene-1131T>C affects the body fat contents of Tibetans and Han nationality population, and APOA5 gene-1131T>C probably affects lipopexia in trunk.
