Comparison of the expression levels of the aberrantly methylated genes as determined using either real-time polymerase chain reaction (PCR) or Western blot analysis in nine samples of sinonasal inverted papilloma (SNIP) and five samples of sinonasal squamous cell carcinomas (SCC) arising in SNIPs. (a) Real-time PCR of microRNA 661 (miR-661) mRNA levels in six SNIP samples and seven SCC samples. (b) Western blot analysis of outer mitochondrial membrane lipid metabolism regulator (OPA3) and plectin (PLEC) protein levels. β-actin was used as the internal control. (c) Relative OPA3 protein levels in Western blot analysis. (d) Relative PLEC protein levels in Western blot analysis. Data presented as mean ± SE; *P < 0.001 compared with SCC group; Student's t-test or one-way analysis of variance.
