PolyADP-ribose polymerase is a coactivator for AP-2-mediated transcriptional activation.
Overexpression of transcription factor AP-2 has been implicated in the tumorigenicity of the human teratocarcinoma cell lines PA-1 that contain an activated ras oncogene. Here we show evidence that overexpression of AP-2 sequesters transcriptional coactivators which results in self-inhibition. We identified AP-2-interacting proteins and determined whether these proteins were coactivators for AP...
متن کاملStrategies for the Use of Poly(adenosine diphosphate ribose) Polymerase (PARP) Inhibitors in Cancer Therapy
Treatments with Poly(adenosine diphosphate ribose) polymerase (PARP) inhibitors have offered patients carrying cancers with mutated BRCA1 or BRCA2 genes a new and in many cases effective option for disease control. There is potentially a large patient population that may also benefit from PARP inhibitor treatment, either in monotherapy or in combination with chemotherapy. Here, we describe the ...
متن کاملThe clinical development of inhibitors of poly(ADP-ribose) polymerase.
A number of inhibitors of DNA repair have been evaluated or are undergoing development as potential cancer treatments. Inhibitors of poly(ADP-ribose) polymerase (PARP) are of particular interest in treating hereditary breast cancers occurring in patients who are carriers of BRCA1 or BRCA2 mutations. In vitro PARP inhibitors are highly cytotoxic to cell lines carrying BRCA mutations while only m...
متن کاملLoss of amplified genes by poly(ADP-ribose) polymerase inhibitors.
A poly(ADP-ribose) polymerase inhibitor, benzamide (BA), was found to induce flat revertants of NIH 3T3 cells that had been transformed by human Ha-ras, rat Ki-ras, rat c-raf, and human ret-II. These genes had been amplified in original transformants, but they were completely eliminated by BA. Contrary to this, endogenous activated Ha-ras in a human bladder carcinoma cell line, T24, was not eli...
متن کاملThe therapeutic potential of poly(ADP-ribose) polymerase inhibitors.
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. Upon binding to DNA breaks, activated PARP cleaves NAD(+) into nicotinamide and ADP-ribose and polymerizes the latter onto nuclear acceptor proteins i...
