Similar to circARID1A knockdown (Fig. 5e, g, i), KHSRP knockdown in IMR-5 cells (validated on RNA and protein levels, Supplementary Fig. 9) reduced cell viability (Fig. 6g) and proliferation (Fig. 6h), substantiating the proposed functions for KHSRP in neuroblastoma cells. This evidence concerns the gene KHSRP and neuroblastoma.
