The researchers found that polypeptide N-Acetylgalactosaminyltransferase 12 (GALNT12) expression was highly linked with poor prognosis in glioblastoma, demonstrating that GALNT12 in U-87 MG glioblastoma cells mediates cell proliferation, migration, and invasion through the PI3K/Akt/mTOR pathway [47]. Here, GALNT12 is linked to glioblastoma.
