[Fat 1 inhibits cell proliferation through the ERK signaling pathway in esophageal squamous cell carcinoma] Elucidation of the mechanism of action of lipid-1 in proliferating esophageal squamous cell carcinoma (ESCC). METHODS: KYSE450 cells were transfected with the plasmid Plko.1-puro-GFP-shRNA-Fat1 and real-time polymerase chain reaction (PCR) was used to verify the efficiency of Fat1 removal. The…
