چکیده

Nucleolar protein 1 (Nol1) is a cell cycle dependent gene highly expressed in proliferating tissues. In order to test whether Nol1 could be used as a marker of dividing neural stem cells within mouse brain, Nol1 expression was analyzed using mouse carrying a gene trap modification of Nol1 gene. High Nol1 expression was found within the hippocampus, olfactory bulb, cerebral and cerebellar cortex. Nol1 was expressed not only in the dividing cells within the brain, but as well in the postmitotic neurons. This suggested a general role of Nol1 in assembling of ribosomes in cells with high protein production.

Telomerase activates transcription of cyclin D1 gene through an interaction with NOL1.

Telomerase is a ribonucleoprotein enzyme that is required for the maintenance of telomere repeats. Although overexpression of telomerase in normal human somatic cells is sufficient to overcome replicative senescence, the ability of telomerase to promote tumorigenesis requires additional activities that are independent of its role in telomere extension. Here, we identify proliferation-associated...

Radiation-induced expression of platelet endothelial cell adhesion molecule-1 in cerebral endothelial cells

Background: Radiation-induced molecular changes on the endothelial surface of brain arteriovenous malformations (AVM) may be used as markers for specific vascular targeting agents. In this study, we examined the level of expression of platelet endothelial cell adhesion molecule-1 (PECAM-1) on brain endothelial cell surface after radiation treatment, with the aim of targeting the radiation-induc...
