Additionally, we observed that the mRNA levels of KIF4A, KIF9, KIF18A, and KIF23 were elevated in LGG patients with a higher histological grade and astrocytoma histologic type than in those with a lower histological grade and histologic type, including oligoastrocytoma and oligodendroglioma. The gene discussed is KIF23; the disease is astrocytoma (excluding glioblastoma).
