Immunofluorescence analysis of GPX4 and NF-κB regulated by cryptotanshinone under ischemia-reperfusion injury. (a) Fluorescence image of GCs stained with GPX4 and NF-κB after different treatments. The photograph shows GPX4 and NF-κB and merge images. (b) Numerical data of the expression of GPX4-positive cells. (c) Numerical data of the expression of NF-κB-positive cells. , compared to control; ^# compared to IR; ^$ compared to IR+CRY; ^& compared to IR+CRY+ferrostatin-1.
