In order to extend these data, two other cell lines, namely the H1299 adenocarcinoma and the H2170 squamous carcinoma cells, were transfected either with a control plasmid or with a plasmid encoding a myc-tagged SRSF1 protein and subjected to G418 selection for 6 days. The gene discussed is SRSF1; the disease is squamous cell carcinoma.
