Matrix Metalloproteinase-9 −1562C/T Gene Polymorphism Is Associated with Diabetic Nephropathy

Figure 1

Electrophoresis of amplification fragments of the MMP9 promoter region for the detection of the −1562C/T polymorphism. Lanes 1, 2, and 5 are the CC genotype; lanes 3, 4, and 7 are the TT genotype; lanes 6 and 8 are the CT genotype. M: DNA molecular weight marker.
