First May PARP bones are bona fide PARP contains Lt a conserved glutamate ETA-receptor that the catalytic activity of t defined by PARP, PARP 8:06, 10, 12, 14 and 16, that Key lacking NAD binding and catalytic glutamate residues that are likely to be inactive. Among the family members, PARP PARP PARP 1 and 2 so far are the only known members whose activity T by DNA strand breaks stimulate targeting Haupts Chlich proteins Involved in chromatin structure and DNA metabolism and PARP PARP 1 and 2 itself Polyation mediated PARP 1 and PARP 2 causes decondensation of chromatin at the sites of Sch, recruitment of repair mA, 1:328 346 www.

Re U 30 December 2010, accepted fifth January 2011, Epub 8th January 2011, VER Published 15th February 2011 Abstract: Poly-polymerase PARP 1 and 2 to a family of enzymes, the reindeer, with NAD as a substrate go, polyation catalyze protein. PARP-1 and PARP 2 catalytic activity t is primarily involved DNAstrand breeze of proteins in chromatin structure and DNA metabolism and provides strong support for a double r Both PARP and PARP-2 stimulation in response to DNA-Sch As the DNA-Sch The sensors and transducers to downstream effectors.
The DNA-Sch The reaction has important implications for the stability of t of the genome and the development of tumors. To manipulate responses to DNA-Sch Ending for selectively to the death of tumor cells, concerning React chtliche efforts at determining the molecular mechanisms to recognize the cells to approximating a Besch Autocompletion and DNA repair to erm concentrated. PARP inhibitors, which compete with NAD in the active site were highly conserved enzyme as a potential new therapeutic strategies, such as chemotherapy and radiopotentiation and treatment of specific cancers with defects in DNA repair as a single agent therapies emerged.
In this study, we highlight the emerging information about the specific and redundant functions of PARP PARP 1 and 2 in the genome surveillance and repair mechanisms of DNA.

In addition, we provide a shield U of ongoing clinical trials with PARP inhibitors and the value of PARP-1 and PARP-2 expression as a prognostic biomarker for cancer.

Pathways and DNA repair processes controlled The cell cycle have important consequences for the stability of t of the genome and the development of tumors. In fact, considerable efforts are concentrated to find answers to DNA-Sch To treat the order selective death of tumor cells. Agents of radiation and chemotherapy cancer treatment are the hours Most frequent, with the DNA-Sch Induced cell death of tumor-ending and there are efforts to understand and improve the current response to cytotoxic chemotherapy. Therefore, PARP inhibitors, which compete with NAD with the enzyme highly conserved active site s as m Potential new therapeutic strategies, such as chemotherapy and radiopotentiation and for the treatment of certain forms of cancer with defective repair of DNA damage caused as a single therapy agents acting by the principle of synthetic lethality t.
