In our study, we monitored the expression of the PAX6 gene in 6 medulloblastoma cell lines and 14 medulloblastoma primary tumor samples: a majority of the cell lines showed moderate expression levels of PAX6 with the exception of the PFSK-1 and D283 cell lines (p = 0.015) (Figure 4E). Here, PAX6 is linked to medulloblastoma.
