SNAI1 and ovarian cancer: Therefore, to analyze the in vivo roles of CHIP and Snail in the peritoneal dissemination of ovarian cancer cells, female BALB/c nude mice were injected intraperitoneally with control SKOV3 (shCont), CHIP‐depleted SKOV3 (shCHIP‐1), or Snail and CHIP double‐depleted SKOV3 (shCHIP‐1/shSnail‐2) cells, after which tumors were allowed to grow for 6 weeks.
