WebCentrosome hyperamplification with the formation of multiple asters and programmed chromosome inactivation in aberrant spermatocytes during male meiosis in … WebMoreover, through the analyses of p53 in SCCHN samples by direct sequencing and by loss-of-heterozygosity test, we found that p53 mutations correlated with occurrence of centrosome hyperamplification. However, in some cases, we observed centrosome hyperamplification in tumors that retained wild-type p53. These tumors contained high …

Web24 dec. 2008 · Here we found that the 2 μm hyperamplification in SUMO pathway mutants requires the homologous recombination repair (HRR) pathway. During vegetative yeast growth, the primary role of HRR is to repair double-strand breaks (DSBs) and to resolve aberrant structures generated during DNA replication ( Paques and Haber, 1999 ; Krogh … Web1 dec. 2003 · γ-Irradiation induced centrosome hyperamplification in MYCN-transduced cells.Cells grown on coverslips were irradiated with 10 Gy at 25°C using a 137 Cs source … Web1 jan. 2003 · In line with this finding, studies have provided evidence that centrosome aberrations result in chromosome missegregation and may lead to malignant transformation.17-19 Specifically, centrosome hyperamplification, induced by p53 mutations or Mdm2 overexpression, has been shown to induce aneuploidy.17 In another … ginza willow avenue bldg 4階
