ANXA5 and ovarian cancer: Attenuated Salmonella typhimurium VNP20009 L-form bacteria can inhibit the growth of mouse epithelial ovarian cancer id8 cells, shown in Fig. 2A. To take the lower right quadrant (Annexin V+/PI− to represent apoptotic cells, FCM apoptosis detection showed that attenuated S. typhimurium L forms can induce mouse ovarian cancer ID8 cell apoptosis at 12 h after their co-culture, shown in Fig. 2B,C.
