Omipalisib inhibited the proliferation of Esophageal squamous cell carcinoma (ESCC) cells. (A) Representative data of 3 independent experiments in cell viability of ESCC exposed to a series of concentrations of omipalisib for 72 hours. (B, C) Representative image of clone formation assay for ESCC cells treated with omipalisib for 72 hours. Clone numbers were calculated. (D) ESCC cells were treated with a series of omipalisib and cisplatin concentrations for 72 hours, and cell viability was measured by MTT assay. (* P<0.05, ** P<0.01, *** P<0.001).
