mAtNOS1 regulates mitochondrial functions and apoptosis of human neuroblastoma cells

Biochim Biophys Acta. 2008 Jun;1780(6):921-6. doi: 10.1016/j.bbagen.2008.02.006. Epub 2008 Mar 4.

Abstract

mAtNOS1 is a novel gene recently reported in mammalian cells with functions that are not fully understood. The present study generated human neuroblastoma SHSY cells over- and underexpressing mAtNOS1 and shows that mAtNOS1 is involved in regulating mitochondrial nitric oxide, mitochondrial transmembrane potential, protein tyrosine nitration, cytochrome c release, and apoptosis of those cells.
