Nonetheless, there was no significant relationship between PLANE and NCOR2-202 expression levels in freshly isolated ESCC and LUAD samples as shown with semi-quantitative RT-PCR (Supplementary Fig. 8e), implying that additional mechanisms are likely involved in regulating NCOR2-202 mRNA expression. The gene discussed is NCOR2; the disease is esophageal squamous cell carcinoma.
