The body weights of rats in the BCP+AS-ODN group (T7:187.3 ± 8.79) and BCP+MS-ODN group (T7:187.19 ± 8.96) were similar to those of rats in the BCP+NS group (T7:182.97 ± 10.23) (P > 0.05, n = 9), which then reduced from day 7 after being injected with Walker256 tumor cells and became lower than those of the sham+NS group (T7:204.08 ± 7.57) (P < 0.0001, n = 9; Figure 3A). This evidence concerns the gene OPN1SW and neoplasm.
