Research Excerpts

Overview

Maitotoxin (MTX) is a ladder-shaped polyether produced by the epiphytic dinoflagellate Gambierdiscus toxicus. It causes influx of calcium through type L voltage-dependent calcium channels (L-VDCC) in GH4C1 rat pituitary cells.

Treatment

Maitotoxin-treated neuroblastoma SH-SY5Y cells. alpha-spectrin breakdown products (SBDPs) of 150 kDa and 145 kDa were produced by cellular calpains. PARP (113 kDa) is also cleaved into a 40 kDa immunoreactive fragment.
