Oligodendrogliomas are a type of glioma that are believed to originate from the oligodendrocytes of the brain or from a glial precursor cell they occur primarily in adults (94% of all primary brain and central nervous system tumors) but are also found in children (4% of all primary brain tumors.

Poly(adp-ribose) polymerase-1 (parp-1) is a member of the parp enzyme family consisting of parp-1 and several recently identified novel poly(adp-ribosylating) enzymes parp-1 is an abundant nuclear protein functioning as a dna nick-sensor enzyme. During adulthood there are two main sources of oligodendrocytes: parenchymal oligodendrocyte precursor cells (opcs) and subventricular zone derived opcs in this review, we will discuss oligodendrogenesis derived from these two sources, and also will highlight their main extrinsic and intrinsic modulators.

In this review, we focus on the growth factor signaling cascades that might be implicated in the control of the self-renewal and differentiation of embryonic, fetal, umbilical cord, and adult stem cells and their progenitors in vitro and in vivo. In order to test our hypothesis that cox-2 expression in oligodendrocytes increases sensitivity to excitotoxic death, these cox-2 transgenic oligodendrocytes were compared to wild-type oligodendrocytes for their susceptibilities to ka induced excitotoxic death.

Our lab has been investigating how oligodendrocytes acquire their identity during development we showed that the identity of these myelin-making cells requires the inactivation of genes that prevent myelin gene expression.
