Curcumin suppressed tumor growth in ESCC PDX models. a-d When the tumors of the mice injected by EG2 (a), EG37 (b), EG60 (c) or EG84 (d) became palpable, the mice were randomly distributed into four groups, and the four groups were administered indicated drugs via intraperitoneal injection three times a week for indicated time. Tumor volumes in each groups were monitored at indicated time. e-h Tumors were excised at the end of the experiment, and their weights were measured. i and j Representative photos of excised tumors in EG60 (I) and EG84 (J) models. *p < 0.05, **p < 0.01
