ATG7 and oligodendroglioma: Based on our findings, the correlation between SRSF1 and autophagy in adult gliomas remains controversial, as SRSF1 levels seemed to correlate to ATG7 and ATG4 in GBM samples and to ATG7 in oligodendrogliomas; conversely, no correlation between SRSF1 and ATG4 was found in oligodendrogliomas.
