Lysine 63-polyubiquitination guards against translesion synthesis-induced mutationsRoland K Chiu
Department of Radiation Oncology, GROW Research Institute, University of Maastricht, Maastricht, Netherlands
PLoS Genet 2:e116. 2006
..Furthermore, we show that polyubiquitination of PCNA occurs in UV-irradiated human cells. Our findings indicate that K63-polyubiquitination guards against environmental carcinogenesis and contributes to genomic stability...
hMMS2 serves a redundant role in human PCNA polyubiquitinationJan Brun
Centre for Cancer Therapeutics, Ottawa Health Research Institute, Ottawa, ON K1H 8L6, Canada
BMC Mol Biol 9:24. 2008
..Recently, it was shown that PCNA polyubiquitination is conserved in human cells and that this modification is dependent on RAD18, UBC13 and SHPRH. However, the role of hMMS2 in this process was not specifically addressed...
Targeting the ubiquitin proteasome pathway for the treatment of septic shock in patientsJan Brun
Ottawa Health Research Institute, Ottawa, ON, Canada K1Y 4E9
Crit Care 13:311. 2009
..We posit that administration of proteasome inhibitors may enhance the survival of patients with septic shock...
Regulation of PCNA polyubiquitination in human cellsJan Brun
Ottawa Health Research Institute, Ottawa, ON K1H 8L6, Canada
BMC Res Notes 3:85. 2010
..The particulars of PCNA ubiquitination have been elucidated in yeast and to a further extent recently in human cells. However, gaps in the detailed mechanism and regulation of PCNA polyubiquitination still persist in human cells...
Proteasome inhibition as a novel therapy in treating rheumatoid arthritisJan Brun
Apoptosis Research Centre, Children s Hospital of Eastern Ontario, 401 Smyth Road, Room 3103, Ottawa, ON, Canada
Med Hypotheses 71:65-72. 2008
..Overall, the purpose of our hypothesis is to suggest a realistic and alternative treatment for patients with refractory and non-refractory arthritic disease...
Formation of lysine 63-linked poly-ubiquitin chains protects human lung cells against benzo[a]pyrene-diol-epoxide-induced mutagenicitySabine A S Langie
Department of Health Risk Analysis and Toxicology NUTRIM, Maastricht University, Maastricht, The Netherlands
DNA Repair (Amst) 6:852-62. 2007
..These findings indicate that K63-polyubiquitination guards against chemical carcinogenesis by preventing mutagenesis and thus contributing to genomic stability...
Cisplatin induces p53-dependent FLICE-like inhibitory protein ubiquitination in ovarian cancer cellsMohammad R Abedini
Department of Cellular and Molecular Medicine, University of Ottawa, Ontario, Canada
Cancer Res 68:4511-7. 2008
..Moreover, we showed that Itch (an E3 ligase) forms a complex with FLIP and p53 upon CDDP treatment. These results suggest that p53 facilitates FLIP down-regulation by CDDP-induced FLIP ubiquitination and proteasomal degradation...
