PCR-RFLPs results. Electrophoresis in 1.5% agarose gels of digested amplified products with Bpu10I and HpyCH4IV restriction enzymes (related to Figure S1 ) ( a ) Digested amplified products of SNP TOX3 rs3803662. ( b ) Digested amplified products of SNP MMP7 rs1943779. TT, CC, and CT genotypes are shown, and lane ML indicates the 100 to 1000 bp molecular gene ruler ladder.
