MAPK8 and central nervous system cancer: No obvious difference was observed for the expression of p‐JNK (Figure 3A,B,E,F) and CX43 (Figure 3A,C,E,G) in glioma cells treated with TMZ/VCR alone and in a combined manner with NHA, but p‐JNK and CX43 expression was significantly repressed in glioma cells treated with TMZ + NHA + AS602801 and VCR + NHA + AS602801.
