SQSTM1 and meningioma: In this study, we have analyzed the immunohistochemical expression of p62 in a cohort of meningiomas (grade I and grade II/III), determining a score for each patient and distinguishing p62 low (ID 0–3) and high expressors (ID 4–6), as elsewhere previously reported for the same autophagy-related proteins in gliomas of CNS [28].
