Thus we used quantitative RT‐PCR to measure the mRNA levels of each FOXM1 isoform with specific primers.14 We observed that the FOXM1c isoform was uniformly expressed at a much higher level than the other three isoforms in all four cell lines (Figure 1B and Figure S1A), indicating the potential importance of FOXM1c in oesophageal cancer progression. The gene discussed is FOXM1; the disease is carcinoma of esophagus.
