Abstract:
:The quail Pax-6 gene is expressed from two promoters named P0 and P1. P0 promoter is under the control of a neuroretina-specific enhancer (EP). This enhancer activates the P0 promoter specifically in neuroretina cells and in a developmental stage-dependent manner. The EP enhancer binds efficiently, as revealed by southwestern experiments, to a 110 kDa protein present in neuroretina cells but not in Quail Embryos Cells and Retinal Pigmented Epithelium which do not express the P0-initiated mRNAs. To study the role of p110 in Pax-6 regulation, we have purified the p110 from neuroretina cells extracts. Based on the peptide sequence of the purified protein, we have identified the p110 as the poly(ADP-ribose) polymerase (PARP). Using bandshift experiments and footprinting studies, we present evidence that PARP is a component of protein complexes bound to the EP enhancer that increases the on rate of the protein complex formation to DNA. Using PARP inhibitors (3AB and 6.5 Hphe), we show that these products are able to inhibit EP enhancer activity in neuroretina cells. Finally, we demonstrate that these inhibitors are able to decrease the expression of the P0-initiated mRNA in the MC29-infected RPE cells which, in contrast to the RPE cells, accumulated the PARP in response to v-myc expression. Our results suggest that PARP is involved in the Pax-6 regulation.

ONCOGENE文献大全abstract::p73 is a member of the p53 family. Recent studies have shown that DNA damage can stabilize p73 protein and enhance p73-mediated apoptosis in a c-Abl dependent manner. To determine what regulates p73 transcriptionally, we analysed the expression of p73 in several cell lines following genotoxic stresses. We found that p...
