Solamargine also activated the expression of caspase-9(15) which plays a central role of in apoptosis signal transduction, a cascade of biochemical reactions inside the cell in ignition of cell death and the regulation of cancer cell apoptosis and caspase -3, a caspase protein(15) that interacts with caspase-9 and dependent on mitochondrial cytochrome c release(15) in initiation of anti cell proliferation and tumor cell invasion.
Additional differentiation of the effect of p53, researchers found that although P53 may have a profound and positive inhibition of the tested cancer line, but its function also was reduced due to the presence of pifithrin-α(15), and mitochondrial translocation inhibitor pifithrin-μ(15), in inhibition of function of p53-mediated apoptosis, in prevented p53 binding to Bcl-xL and Bcl-2 (15)at the mitochondria ..., thus partially reversing the anti proliferative activity of solamargine.
Dr. Li X(15), the lead scientist said, "(the results finding, indicated that) Solamargine activates the mitochondria-mediated apoptotic pathway in U2OS cells via both p53 transcription-dependent and -independent mechanisms".
Although eggplant with abundantly bioactive compounds may be considered as function food in reduced risk and treatment of cancers, however, according to Dr. Shimada A. in an one year (continuous 2 days for 12 months) food surveys held at 5 areas in Japan, the frequency of intake eggplant may associate to increase risk of gastric cancer and gastric cancer mortality rate(7), but may account partly for the geographic variation in gastric cancer mortality in Japan(11).
