Relative expressions of AK096725 and ENST00000453068 in 70 paired RCC tumor specimens and adjacent normal tissue samples determined by qRT-PCR.

<p>The expression level of lncRNAs was normalized using β-actin as an internal control. The median in each triplicate was used to calculate the relative lncRNA concentration using the comparative ΔCt method. The lines are at mean with SEM. AK096725 was found significantly differentially upregulated in tumor specimens (<i>P</i> = 0.043), while ENST00000453068 was identified as significantly downregulated in tumor specimens (<i>P</i><0.001).
