TERT expression by real time PCR in ovarian cancer and HT29 cell lines. Days of treatment are shown on the x-axis and TERT expression on the y-axis. TERT expression was determined in absence (red bars; CTRL) and in presence (blue bars) of 1 μM ATRA. The last cell line HT29 was used as a negative control. Each bar represents the mean (±SD) of three independent experiments
