Figure 3From: Silencing cytokeratin 18 gene inhibits intracellular replication of Trypanosoma cruzi in HeLa cells but not binding and invasion of trypanosomesCK18 RNAi treatment does not cause apoptosis of HeLa cells. HeLa cells were left untreated (Medium) or transfected with CK18 or control RNAi. After 34 h, cells were labeled with propidium iodine (PI) and Annexin-V-FITC. Cells were analyzed by FACS.Back to article page
