Fig. 5From: Investigation of synergistic mechanism and identification of interaction site of aldose reductase with the combination of gigantol and syringic acid for prevention of diabetic cataractAR mRNA expression after treatment with gigantol, syringic acid, and the combination. The expression of AR mRNA is normalized using the housekeeper gene (β-actin), which is evenly expressed in rat lens cells. Compared with the normal control group, mRNA levels of the AR gene increased 4.85-fold in Group II and 1.23-fold in Group V; *p < 0.01 vs Group I, Group III, Group IV and Group V. **p < 0.05 vs Group III and IVBack to article page
