Western blot analysis of the U-87 cell lysates where the groups are untreated (first column), temozolomide: TEMO, positive control (second column), and AgZE (third column) with blots of (a) caspase 8 (first blot), p53 (second blot), STAT3 (third blot), and GAPDH (fourth blot), (b) graphical representation of quantification of Western blots using Image J analysis. Upon treatment with AgZE, U-87 cell protein lysates show upregulation of caspase-8 as well as p53 with slight upregulation of STAT3 compared to untreated samples. GAPDH is used as loading control.
