SRSF3 and colorectal carcinoma: RNA immunoprecipitation in LIM1215 cells overexpressing SRSF3‐GFP showed that SRSF3 does not directly interact with CDKN1A mRNA (Fig EV4F), and a CDKN1A 3′UTR luciferase reporter assay (Wang et al, 2008) further demonstrated that SRSF3 regulated CDKN1A via miR‐17/20a in human CRC cells (Fig 5D).
