PTEN is positively correlated with PLAC2. (A) PTEN mRNA expression levels measured by reverse transcription-quantitative PCR and analysis by paired t-test analysis showed that expression levels of PTEN mRNA were significantly decreased in Rb tissues compared with non-tumor tissues *P<0.05. Pearson's correlation coefficient showed that PTEN mRNA and PLAC2 were positively correlated both in (B) non-tumor tissues and (C) Rb tissues. Rb, retinoblastoma; PLAC2, placenta-specific 2.
