The inhibitive effect of proteasome inhibitor MG132 on cell proliferation and colony formation in ESCC cells. MTT assays were used to assess the cell viability of cells constantly treated by MG132 at the indicated time points. The concentrations of MG132 are indicated in the figure. (A) KYSE30 cell line; (B) KYSE140 cell line; (C) KYSE180 cell line. Colonies were counted 2 ~ 3 weeks after cells were seeded and constantly treated by MG132 at the indicated concentrations. (D) Representative photographs of colony formation in KYSE30 cell line; (E) Representative photographs of colony formation in KYSE180 cell line; (F) Statistical analysis in KYSE30 and KYSE180 cell lines. Data are represented as mean +/- SD.
