MCT-1 promotes cell survival in serum-starvation culture. EC155-Vector or EC155—MCT-1 cells (2 × 10⁵cells /mL) were seeded in triplicate wells in 12-well plates in serum-starved culture (0.2% FBS). Cell viability was analyzed by using the trypan blue exclusion method at certain time points. Data were presented as percentage of viable cells (mean ± SD) and were derived from 3 independent experiments with each clone. The viability of EC155—MCT-1 after 72 hours of serum starvation was significantly higher than that of EC155-vector control.
