Figure 6.
Semi-quantitative analysis of immunohistochemical staining of GRP78, p-ERK and caspase-12 in the kidney, based on the percentage of positively stained areas in the tubules and the intensity of staining. Animals were divided into four groups: the control group (N), the cisplatin (CP) group (C), the grape seed proanthocyanidin extract (GSPE) group (G) and the CP+GSPE group (C+G). The expression of GRP78, p-ERK and caspase-12 was significantly increased in the C group compared to the N group and significantly decreased in the C+G group compared to the C group.*Statistically significant difference compared to the N group (p<0.05); #statistically significant difference compared to the C group (p<0.05).
