SOCS7 and neoplasm: We observed that SOCS7 overexpression significantly increased the expression of SOCS7 in tumor xenografts at day 33 (Fig. 2o) and that the volume of the developed tumor at days 21–33 (Fig. 2p) and the tumor weight at day 33 (Fig. 2q) in mice injected with SOCS7-overexpressing CAOV3 cells were substantially (P < 0.01) lower than those in the control mice.
