Transient global cerebral ischemia induces up-regulation of MLTKα in hippocampal CA1 neurons.

MLTK (mixed-lineage kinase-like mitogen-activated protein triple kinase) is a member of the mitogen-activated protein kinase family and functioned as a mitogen activated kinase kinase kinase. MLTKα, one of the alternatively spliced forms of MLTK, could activate the c-Jun N-terminal kinase pathway, which involved in cellular stress responses and apoptosis. But the role of MLTKα in neural apoptosis was still unclear.
