BAX and neoplasm: To this end we analyzed the expression marker proteins p53/bax (pro‐apototic) and bcl‐2 (anti‐apoptotic) which play a key role in apoptosis pathways and tumor growth.[47] Our data indicate a positive correlation between the expression of bax and p53 proteins and the concentration of 1 (Figure 3 c,e), while the expression of bcl‐2 is down‐regulated at increasing concentration of 1 (Figure 3 d,f).
