Figure 3. Identification of PCTK1 as an elevated circulating mRNA in NSCLC patients. (A) The PCTK1 mRNA levels in the plasma were determined by reverse transcription quantitative PCR and normalized to that of the β2-microglobulin (B2M) transcript. (B) Receiver operating characteristic curve analysis of the diagnostic efficacy of plasma PCTK1 RNA levels.
