Figure 1. miR-24 targets the melatonin-p53 pathway.
(A) Graphs show the sequence coverage, as well as the signal intensity, of H2AFX (H2AX) and MAPK12 (p38-γ) in both vehicle and melatonin treated HCT 116 cell line. (B) HCT 116 and MCF-7 cells have been treated with melatonin for 24, 48 and 72 hours. The ratio between miR-24 and RNU49 levels, normalized to their respective untreated controls, are indicated in the graphs. (C) HCT 116 cells have been transfected with either negative control (NC) or miR-24 mimic and the indicated Dual Luciferase reporters. Values for NC are set to 1. *p < 0,01. (D, E) HCT 116 and MCF7 cells have been transfected with the indicated mimic (D) or LNA (E) and subjected to quantitative Real-Time PCR. Values have been normalized to NC or LNA. (F, G) Cells have been transfected with the indicated mimic (F) or LNA (G) and cell extracts have been subjected to immunoblot with the indicated antibodies. Numbers indicate signal quantification normalized to NC or LNA-NC.
