Changes in SCF/GAPDH and C-kit/GAPDH by RT-PCR analysis. (A) Representative images of gel electrophoresis of GAPDH,SCF, and c-kit in rats of each group. (B) Group levels of relative mRNA expression of SCF and c-kit, with products quantified by ratio to GAPDH. : Group I=normal control rats (n=10); : Group II=diabetic control rats (n=10); : Group III=diabetic + curcumin treated rats (n=10); : Group IV=normal + curcumin treated rats (n=10). All values are expressed as the mean ± SD. *p<0.01 (compared to Group I.), # p <0.05 (compared to Group II), Δp >0.05 (compared to Group I).
