Nucleostemin: New Stabilizer of ARF.
As an essential nucleolar protein for ribosomal assembly and protein production, nucleolar GTPase nucleostemin (NS) is often highly expressed in actively proliferative cells, including stem cells and cancer cells, and therefore thought to play an oncogenic role in various types of human cancers [1]. However, given the heterogeneity of cancer cells, imbalanced expression of NS could trigger dist...
متن کاملNucleostemin and ASPP2 expression is correlated with pituitary adenoma proliferation
Nucleostemin is a GTP-conjugated protein located in the nucleoli of stem cells and certain cancer cells, and maintains cellular self-renewal. The present study aimed to evaluate nucleostemin as a potential target for pituitary adenoma gene therapy by investigating nucleostemin and apoptosis-stimulating of p53 protein 2 (ASPP2) expression and their effect on pituitary adenoma cell proliferation....
متن کاملMultiple controls regulate nucleostemin partitioning between nucleolus and nucleoplasm.
Nucleostemin plays an essential role in maintaining the continuous proliferation of stem cells and cancer cells. The movement of nucleostemin between the nucleolus and the nucleoplasm provides a dynamic way to partition the nucleostemin protein between these two compartments. Here, we show that nucleostemin contains two nucleolus-targeting regions, the basic and the GTP-binding domains, that ex...
متن کاملNucleostemin as a possible progenitor marker of corneal epithelial cells
PURPOSE Nucleostemin, a nuclear protein involved in the regulation of cell cycle and proliferation, is a candidate marker for various stem cells. We examined the expression of nucleostemin as a marker of differentiation and senescence in corneal epithelial progenitor cells. METHODS Nucleostemin expression in normal mouse corneal epithelium was examined by RT-PCR, as well as in cultured mouse ...
متن کاملImmunohistochemical study of doublecortin and nucleostemin in canine brain
Finding a marker of neural stem cells remains a medical research priority. It was reported that the proteins doublecortin and nucleostemin were related with stem/progenitor cells in central nervous system. The aim of the present immunohistochemical study was to evaluate the expression of these proteins and their pattern of distribution in canine brain, including age-related changes, and in non-...
