Abstract

The alterations in cancer cell's metabolism have been associated with enhanced
oxidative stress. Therefore, a partially purified SOD-like activity protein from the
roots of Raphnus sativus (R. sativus) and low-molecular-weight heparin (LMWH)
were tested for their abilities to inhibit the growth of Ehrlich ascites carcinoma cells
(EAC) intraperitoneally implanted in albino mice. Ninty mice were randomly divided
into 6 groups. The antitumor effect of the partially purified protein and LMWH were
assessed by estimating transforming growth factor Beta (TGF-β) and vascular
endothelial growth factor (VEGF) in serum. Also, tumor volume, median survival
time (MST), total lipids, DNA and RNA contents in liver tissues as well as liver
function tests and the redox status were estimated. TGF-β, VEGF, DNA, RNA, and
malondialdehyde (MDA) levels in addition to serum alanine transaminase (ALT) and
gamma glutamyl transferase (GGT) activities and tumor volume were highly
significantly increased (P<0.001) in the untreated EAC-bearing mice compared to
those of the control. However, total lipids in liver tissues and serum albumin were
highly significantly decreased in the same group compared to the corresponding
values of the control group. All these parameters were restored to their normal levels
in the partially purified extract and LMWH treated EAC-bearing mice groups
compared to the untreated EAC-bearing mice. It could be concluded that, the partial
purified protein with SOD-like activity from the roots of R. sativus and the LMWH
have a remarkable anti-tumor activity against EAC cells in Swiss albino mice through
its potent effect on both TGF-β and VEGF.
