Chromosomal instability and acquired drug resistance in multiple myeloma
Chromosomal instability (CIN) is an important hallmark of human cancer. CIN not only contributes to all stages of tumor development (initiation, promotion and progression) but also drives, in large measure, the acquisition of drug resistance by cancer cells. Although CIN is a cornerstone of the complex mutational architecture that underlies neoplastic cell development and tumor heterogeneity an...
متن کاملTransfer Potential of Plasmids Conferring Extended-Spectrum-Cephalosporin Resistance in Escherichia coli from Poultry
Escherichia coli strains resistant to extended-spectrum cephalosporins (ESC) are widely distributed in Norwegian broiler production, and the majority harbor transferable IncK or IncI1 plasmids carrying blaCMY-2 Persistent occurrence in broiler farms may occur through the survival of ESC-resistant E. coli strains in the farm environment, or by transfer and maintenance of resistance plasmids with...
متن کاملMechanisms of Evolution in High-Consequence Drug Resistance Plasmids
The dissemination of resistance among bacteria has been facilitated by the fact that resistance genes are usually located on a diverse and evolving set of transmissible plasmids. However, the mechanisms generating diversity and enabling adaptation within highly successful resistance plasmids have remained obscure, despite their profound clinical significance. To understand these mechanisms, we ...
متن کاملStudy of Multiple-Drug Resistance Transfer Factors from Isolated E. coli of Poultry Farms to Salmonella typhimurium
Different studies on animals in around the world show that there are multiple-drug resistance in strains of Escherichia coli (E. coli). Such microorganisms are notorious for the extension of colibacillosis in poultry, which great economic losses bring for the poultry industry. This study was carried out to determine drug resistance and resistance factor transfer in E. coli strains isolated from...
متن کاملComplete DNA sequence and analysis of the transferable multiple-drug resistance plasmids (R Plasmids) from Photobacterium damselae subsp. piscicida isolates collected in Japan and the United States.
Photobacterium damselae subsp. piscicida is a bacterial fish pathogen that causes a disease known as pasteurellosis. Two transferable multiple-drug resistance (R) plasmids, pP99-018 (carrying resistance to kanamycin, chloramphenicol, tetracycline, and sulfonamide) and pP91278 (carrying resistance to tetracycline, trimethoprim, and sulfonamide), isolated from P. damselae subsp. piscicida strains...
