DDX53 and neoplasm: Compared to the CT26 tumor growth of mice bearing unilateral CT26 tumor that received only PBS (PBS group), mice bearing bilateral heterogeneous tumors (4T1 on the left flank and CT26 on the right flank) showed similar CT26 tumor growth on the right flank after RFA was given on the left flank (Figure 5B), indicating no evident antitumor effects.
