Applying significance analysis of microarrays, 52 genes, involved in important pathways related to cancer, were differentially expressed between plasma cells from healthy subjects and patients with stringently defined monoclonal gammopathy of undetermined significance/smoldering multiple myeloma and symptomatic multiple myeloma. Unsupervised hierarchical clustering of 351 multiple myeloma and 44 cases of monoclonal gammopathy of undetermined significance and 16 cases of multiple myeloma with a monoclonal gammopathy of undetermined significance history, created two major cluster branches, one containing 82% of the monoclonal gammopathy of undetermined significance cases and 28% of the multiple myeloma, termed monoclonal gammopathy of undetermined significance-like multiple myeloma. Using the same clustering approach on an independent cohort of 213 cases of multiple myeloma revealed 27% with monoclonal gammopathy of undetermined significance-like multiple myeloma which, despite a lower incidence of complete remission, was associated with low-risk clinical and molecular features and superior survival. The monoclonal gammopathy of undetermined significance-like multiple myeloma signature was also seen in patients surviving more than 10 years after autotransplant.11-13-2008

20120302461GFP MUTAGENESIS AMPLIFICATION: USE OF A FLUORESCENCE-ANTIBIOTIC RESISTANCE FUSION DUAL REPORTER CONSTRUCT TO PROVIDE QUANTITATIVE AND HIGHLY SENSITIVE DETECTION OF MUTATIONS - A reversion mutation assay that is unique in providing a quantitative readout for mutagenesis. This assay is based on the creation of a functional GFP-β-lactamase fusion protein as a reporter providing both antibiotic resistance and fluorescence. This dual reporter is placed in a multicopy plasmid to increase the number of targets, with a reversion site at the N-terminus. Rare mutations at the reversion site allow read-through of the fusion protein, producing both beta-lactamase (providing antibiotic resistance) and GFP (emitting fluorescence). In the presence of carbenicillin, beta-lactamase production confers a selective advantage that allows amplification of mutant plasmids, raising the level of fluorescence emitted by GFP to levels that are detectable by fluorimetry. A window of time can be found where fluorescence is proportional to the number of mutation events at the reversion site, making fluorescence a quantitative measure of mutagenesis. Quantitative (as opposed to binary) detection of mutations allows substantial savings in test sample. This has applications in drug discovery, allowing high-throughput screening for DNA-targeting compounds and early pre-screening of leads for potential carcinogenic activity. The increased sensitivity of this assay also facilitates monitoring complex environmental samples.11-29-2012
