Figure 1. miR-20b is upregulated and miR-125a is downregulated in radioresistant esophageal cancer cells KYSE-150R. (A) The relative levels of miR-20b in parental (KYSE-150) cells and radioresistant (KYSE-150R) cells. (B) The relative levels of miR-125a in KYSE-150 cells and KYSE-150R cells. *P<0.05 by Student’s t-test.
