SORBS2 and ovarian cancer: First, to identify endogenous RNA targets of SORBS2 in ovarian cancer cells, we performed high-throughput RNA immunoprecipitation sequencing (RIP sequencing) in A2780s ovarian cancer cell lines expressing Flag-tagged SORBS2 and control A2780s ovarian cancer cells (Fig. 3a; Additional file 2: Figure S7c and Additional file 2: Figure S9a–b).
