| Research Abstract |
To assess whether early lung cancer prediction might be informed by an mRNA assay for various increased genes in peripheral blood mononuclear cells (PBMNCs) and tumor tissues, we examined specimens taken from 65 carcinoma patients and 15 controls. PBMNCs and tumor-tissue specimens were taken for measurement of the mRNAs of 93 genes by TaqMan low density arrays. In the PBMNCs of the controls, 8 genes were not detected. In PBMNCs, FGF2 mRNA/GAPDH mRNA, MMP9 mRNA/GAPDH mRNA, NANOG mRNA/GAPDH mRNA, PPBP mRNA/GAPDH mRNA, S100A4 mRNA/GAPDH mRNA, STAT3 mRNA/GAPDH mRNA, and TYMP mRNA/GAPDH mRNA levels were significantly higher in the carcinoma patients than in the controls. Although the level of PPBP mRNA/GAPDH mRNA in PBMNCs appeared to correlate with that in tumor-tissue specimens, the coefficient of determination was too small (0.087). Unfortunately, measurement of mRNAs in PBMNCs may not be useful for the early diagnosis of lung carcinoma.
