Effect of VEGF-C siRNA and endostatin on ring formation and proliferation of esophageal squamous cell carcinoma lymphatic endothelial cells

OBJECTIVE: To study the effects of vascular endothelial growth factor C small interfering RNA and endostatin on esophageal squamous cell carcinoma-related ring formation in vitro and proliferation of lymphatic endothelial cells. MATERIALS AND METHODS: KYSE150 cells were subjected to analysis of cell transfection and endostatin operation. The groups were as follows: negative group, blank group, negative plus endostatin group, endostatin group, SG1 group, SG2 group, SG1 plus endostatin group, and SG2 plus endostatin group. The esophageal cancer-related microlymphatic endothelial cells were three-dimensionally cultured. Cell Counting Kit-8 (CCK-8) assay was employed to detect cell proliferation. RESULTS: The negative group’s three-dimensional culture result was the highest, followed by the blank group, negative plus endostatin group, endostatin group, SG2 group, SG1 group, SG1 plus endostatin group, and SG2 plus endostatin group. The quantity of living cells in the blank group was the highest, followed by the negative control, endostatin, SG2, SG1, negative plus endostatin, SG1 plus endostatin, and SG2 plus endostatin groups. CONCLUSION: Both vascular endothelial growth factor C small interfering RNA and endostatin could inhibit ring formation in esophageal squamous cell carcinoma and proliferation of lymphatic endothelial cells.
