Reverse correlation between expression of ZNFX1 and ZFAS1 in lung cancer specimens. A qRT-PCR analysis of ZFAS1 and ZNFX1 mRNA levels in 51 lung cancer specimens and their paired adjacent normal lung tissues. B Correlation patterns and corresponding correlation coefficient values between ZFAS1 and ZNFX1 in 51 lung cancers. Coefficient r = −0.2726, p < 0.001. C qRT-PCR analysis of ZFAS1 and ZNFX1 expression in lung cancers from smokers/former smokers versus never smokers. * p < 0.05; **p < 0.01
