Identification of Genes Potentially Regulated by Human Polynucleotide Phosphorylase (hPNPaseold-35) Using Melanoma as a Model
Human Polynucleotide Phosphorylase (hPNPase(old-35) or PNPT1) is an evolutionarily conserved 3'→ 5' exoribonuclease implicated in the regulation of numerous physiological processes including maintenance of mitochondrial homeostasis, mtRNA import and aging-associated inflammation. From an RNase perspective, little is known about the RNA or miRNA species it targets for degradation or whose expres...
متن کاملFrom polynucleotide phosphorylase to neurobiology.
In the fall of 1944, I enrolled at the Hebrew University of Jerusalem. The student body numbered about 700 and the choice of faculties was somewhat limited.My hopewas to study medicine, but the plans to open a medical school were still at the drawing board stage. I therefore chose to study chemistry with biochemistry and bacteriology as minor subjects, which I thought I would need later if I we...
متن کاملPolynucleotide phosphorylase of Micrococcus lysodeiktpcus. III. The apparent arsenolysis of nucleoside diphosphates by polynucleotide phosphorylase.
The enzyme, polynucleotide phosphorylase, catalyzes the polymerization of nucleoside diphosphates to polyribonucleotides with the formation of inorganic orthophosphate (1, 2). The reaction is readily reversible, and the phosphorolysis of polyribonucleotides has been studied extensively (3-6). Several recent reviews (7-9) afford extensive summaries of the literature. In the accompanying paper (l...
متن کاملIdentification and cloning of human polynucleotide phosphorylase, hPNPase old-35, in the context of terminal differentiation and cellular senescence.
Terminal differentiation and cellular senescence display common properties including irreversible growth arrest. To define the molecular and ultimately the biochemical basis of the complex physiological changes associated with terminal differentiation and senescence, an overlapping-pathway screen was used to identify genes displaying coordinated expression as a consequence of both processes. Th...
متن کاملStudies on Polynucleotides Synthesized by Polynucleotide Phosphorylase
The preparation of synthetic ribonucleic acid in which one of the nucleotide species is labeled with P32, makes possible studies on the distribution of the labeled nucleotide in the polynucleotide chain. Fig. 1 presents the structure of a polynucleotide in which labeled adenylic acid is randomly distributed. Hydrolysis of such a polymer with snake venom phosphodiesterase (Fig. 1A) will yield a ...
