Fig. 2From: Involvement of epigenetic modification of TERT promoter in response to all-trans retinoic acid in ovarian cancer cell linesCell viability assay by MTT test in ovarian cancer cell lines. A) Days of treatment are shown on the x-axis and the percentage of viable cells on the y-axis. Cell viability was determined in absence (CTRL, ●) and in presence of 1 μM of ATRA (▲). HT29 cells were used as a negative control. B) Histogram showing cell survival (percentage) after 7 day of treatment respect to control. Each bar represents the mean (±SD) of three independent experimentsBack to article page
