We examined the correlation between gene polymorphisms in hypoxia-inducible factor-1α (HIF-1α) Pro582Ser and type 2 diabetic nephropathy (DN). A total of 244 subjects with type 2 diabetes were recruited. The 1285-bp locus polymorphism of HIF-1α exon was detected using polymerase chain reaction-restriction fragment length polymorphism. C/T single nucleotide polymorphisms were detected at the site of 1285 bp of the HIF-1α exon, from a proline to a serine (Pro582Ser). The frequency of CT heterozygotes was significantly higher in DN patients than in diabetes patients (P
In the present study, we examined whether hypoxia-inducible factor-1α (HIF-1α) polymorphisms are associated with the susceptibility to chronic obstructive pulmonary disease (COPD). One hundred and twenty patients with COPD and 112 healthy controls were recruited from the Han population in Southern China. Polymerase chain reaction-restriction fragment length polymorphism was used to assess the C1772T and G1790A polymorphisms in the HIF-1α gene, and differences in genotypes between the 2 groups were compared.
