T-type calcium channels regulate medulloblastoma and can be targeted for therapy.

Purpose: The goal of this study was to investigate the role and therapeutic targeting of T-type calcium channels in medulloblastoma, a common and deadly pediatric brain tumor that arises in the cerebellum.

Methods: T-type calcium channel expression was assessed in publicly available bulk and single cell RNA-seq datasets. The effects of T-type calcium channel blocker mibefradil on cell growth, death and invasion were assessed with cell counting, alamar blue, trypan blue and transwell assays.
