p62 is a key component of protein aggregates found in brains of neurodegenerative diseases in which oxidative stress is involved in the pathogenesis. p62 was induced in SH-SY5Y, a neuroblastoma cell line, by hydroxydoparnine or $C_2-ceramide$ known to be related to neurodegenerative diseases. The over-expression of p62 showed the neuroprotective effect against the ceramide induced cell death. In addition, p62 became insoluble and cleaved forms as time proceeded after the ceramide treatment, suggesting the mechanism by which p62 is associated with aggregates in neurodegenerative diseases.
