From: The long non-coding RNA BC200 (BCYRN1) is critical for cancer cell survival and proliferation
Cell cycle arrest reduces BC200 expression approximately 10-fold. (a) MCF-10A cells were treated with Lovastatin (40 μM), thymidine (2 mM), RO3306 (10 μM), nocodazole (0.1 μg/mL), or serum deprivation for 24 h to arrest cells in G1, S, G2, M and G1-phase respectively. BC200 expression was assessed by RT-qPCR and corrected to the housekeeping gene GAPDH. Data represents the mean of three replicates +/− standard error. Similar results were observed in HMEC cells (data not shown). (b) MCF-10A cells were arrested in the G1-phase by treatment with Lovastatin for 24 h. Cells were washed and released with mevalonic acid and collected every two hours to monitor BC200 and MYC expression and cell cycle phase. BC200 and MYC expression are represented on the left y-axis and the fraction of cells in each phase as determined by DNA content is represented by the right y-axis. (c) Histograms for selected time points demonstrate synchronous progression through the cell cycle following release from Lovastatin arrest. DNA content is monitored by propidium iodide fluorescence intensity on the x-axis (FL3-H)
