Figure 1.

miR-122 expression is detected in hepatocyte cells but not in NSCLC cells, A549 or H460.

Notes: Total RNA, which was extracted from the indicated cell lines, was analyzed by real-time RT-PCR, and β-actin was chosen as loading control. (A and C) The endogenous level of miR-122 or β-actin was shown as DNA gel electrophoretic bands. (B and D) Relative RNA level was shown as mean ± SD from triplicate measurements with similar results. The expression of miR-122 in NSCLC via ad vector is shown as photograph (E and F) or relative RNA level (D and G). *P<0.05.

Abbreviations: NSCLC, non-small-cell lung cancer; RT-PCR, reverse transcription polymerase chain reaction.
