Another circular RNA has already been identified, circSMARCA5, which has an impact on the expression of VEGFA48; however, differently from circ_0076611 which enhances VEGFA translation, circSMARCA5 affects VEGFA splicing, favoring the pro- to anti-angiogenic VEGFA isoforms ratio, thanks to its ability to sponge SRSF1 protein in glioblastoma multiforme cells. Here, SRSF1 is linked to glioblastoma.
