Furthermore, SRSF3 has been found to facilitate the alternative splicing of isoforms 1 and 2 of the Interleukin Enhancer Binding Factor 3 (ILF3), which results in a loss of cell cycle regulation functions.391,392 In the context of neuroblastoma, the increased expression of HNRNPA1 and PTBP1 promotes the inclusion of PKM exon 10 in an ASE, thereby contributing to tumor progression.393. This evidence concerns the gene HNRNPA1 and neoplasm.
