Figure 4. The effect of CDKN1A on the therapeutic response of GBM patients. (A–C) GSE43452, GSE65363 and GSE80729 are three microarray datasets related to TMZ chemotherapy and are employed to identify the impacts of CDKN1A expression levels on GBM therapy. (D) the expression levels of CDKN1A might be negative correlation with TMZ activity in 79 glioma cells from CellMinerCDB.
