Figure 7. Treatments with ginger extract, selenium, and their combinations modulated the ocular mRNA expression of TRPV1 (A) and TRPM2 (B) in diabetic rats.Gene expression was analyzed by quantitative real-time PCR, and results are shown as the mean ± SD (n=8).Triple asterisks (*p < 0.001) indicate a statistically significant difference compared to the control (C) group.**The symbols #, +, and ^ denote significant differences compared to the untreated diabetic (D) group at #p < 0.05, +p < 0.05, ^p < 0.05, and ^^^p < 0.001.
