Interestingly, in our glioma series, out of the 34 GBM cases which showed high immunohistochemical expression of SRSF1, high ATG7 and ATG4 levels were found in 27/34 (79%) and 23/34 (68%) cases, respectively; among the 15 cases of oligodendroglioma with high SRSF1 immunoexpression, 11/15 cases (73%) had also high levels of ATG7. Here, ATG7 is linked to central nervous system cancer.
