We observed the polymorphism distribution and coaction of uncoupling protein 3（UCP3）-55C/T,adiponectin（APN）＋45T/G and tumor necrosis factor（TNF）-α-308G/A on the onset and development of T2DM in a Northern Chin...We observed the polymorphism distribution and coaction of uncoupling protein 3（UCP3）-55C/T,adiponectin（APN）＋45T/G and tumor necrosis factor（TNF）-α-308G/A on the onset and development of T2DM in a Northern Chinese Han population of 213[100 type 2 diabete（T2DM） patients and 113 health control subjects] by polymerase chain reaction-restriction fragment length polymorphisum（PCR-RFLP） method.Results demonstrate the polymorphism of UCP3-55C/T,APN＋45T/G,and TNF-α-308G/A related to T2DM onset and developement.And the individuals carrying UCP3-55T,APN＋45G and TNF-α-308A allele had higher T2DM risk.Those results are the first report to evaluate the association of the coaction of UCP3,APN,TNF-α genes polymorphism on T2DM risk and the susceptibility of T2DM in the Northern Chinese Han population.展开更多
