SRSF1 and neoplasm: A high correlation between SRSF1 and SRSF3 was observed (Supplementary Fig. 5A), which is noteworthy because the expression of SRSF1 and SRSF3 genes is mutually regulated and coexpressed in normal and tumour cells, and SRSF3 is able to regulate the alternative splicing of SRSF1 gene30.
