From: MiR-34a is up-regulated in response to low dose, low energy X-ray induced DNA damage in breast cells
microRNA expression by qRT-PCR in MCF-10A, MCF-7 and T-47D cell lines, assessed 4 and 24 hours after 5 Gy/30 Kv X-ray irradiation event. Relative expression of miRNAs (A) miR-34a, (B) let-7a and (C) miR-21 was calculated by ΔΔCT method and the acquired fold change values are relative to their respective non-treated mock control. * significant difference in comparison irradiated versus non-treated cells (Student’s t test P ≤ 0.05).
