RESUMEN
K121Q polymorphism of membrane gl yc oprotein PC-1 gene was assayed by PCR-RFLP and distributions of Q, K alleles a nd KQ, KK genotypes were observed in 92 normal controls and 107 type 2 diabetic patients. The results suggest that Q allele is related to type 2 diabetes and ty pe 2 diabetes with obesity, hypertension and hyperlipidemia.
RESUMEN
Objective To investigate the relationship between ?3 adrenergic receptor(?3AR) gene Trp~(64)Arg mutation and insulin resistance(IR) in Chinese.Methods The 120 patients with type 2 diabetes mellitus(group DM) and 80 nondiabetic subjects as normal controls(group N)were involved in the study.Polymerase chain reaction(PCR) and the restriction fragment length polymorphism analysis(PCR-RFLP) were used to determine the ?3AR genotype.The indexes such as body weight,height,waist circumstance,hip circumstance,blood pressure,lipids,fast plasma glucose and insulin were detected in all subjects.The IR was estimated by homeostasis model assessment(HOMA-IR).The patients in the diabetes group were divided into relative insulin sensitive group and relative insulin resistant group by the 75th percentile HOMA-IR.Results The BMI of the patients with the ?3AR Trp~(64)Arg mutation was significantly higher than that of those without the mutation(P
