The soluble urokinase plasminogen activator receptor (suPAR) has been shown to be a strong prognostic biomarker for tuberculosis (TB). In the present study, the profiles of plasma suPAR levels in pulmonary TB patients at high risk for multidrug resistance were analyzed and compared with those in multidrug resistant (MDR)-TB patients. Forty patients were prospectively included, consisting of 10 ...

Multidrug resistance (MDR) is a main cause of failure in the chemotherapeutic treatment of malignant disorders. One of the well-known genes responsible for drug resistance encodes the multidrug resistance- associated protein (MRP1). The association of MRP1 with clinical drug resistance has not systematically been investigated in Iranian pediatric leukemia patients. We therefore applied real-tim...

In adult T-cell leukemia/lymphoma (ATL), it is difficult to achieve remission and the reason for the resistance to chemotherapeutic agents may be linked to the presence of multidrug resistance (MDR) proteins. Lung resistance-related protein (LRP), multidrug resistance-associated protein and P-glycoprotein are three MDR proteins which we examined in ATL cells using multiparametric flow cytometry...

This study examined the effects of suppressing c-fos oncogene expression on multidrug resistance (MDR). A2780S human ovarian carcinoma cells with resistance to actinomycin D were isolated and the resultant A2780AD cells exhibited the MDR phenotype. A hammerhead ribozyme designed to cleave fos RNA cloned into the pMAMneo plasmid was transfected into A2780AD cells. Induction of the ribozyme resul...

The antimicrobial susceptibility of Escherichia coli isolates associated with various types of infections in dogs and cats was determined. The studied isolates were most frequently susceptible to fluoroquinolones and the extended-spectrum cephalosporins (ESCs), antimicrobials commonly used in treatment of infections in companion animals. However, an increase in the percentage of strains resista...

Multidrug-resistant (MDR) Salmonella enterica subsp. enterica serotype Newport has been a long-standing public health concern in the United States. We present the complete sequences of six IncA/C plasmids from animal-derived MDR S. Newport ranging from 80.1 to 158.5 kb. They shared a genetic backbone with S. Newport IncA/C plasmids pSN254 and pAM04528.

A multidrug-resistant (MDR) Escherichia coli strain from a human-associated pulsotype within sequence type ST131 (O25:H4) colonized three of five dogs and cats within a household. Of the four other colonizing strains identified, two were MDR and two colonized multiple hosts. The ST131 strain uniquely exhibited high resistance and virulence scores.

Pseudomonas aeruginosa (P. aeruginosa) bacteremia causes significant mortality rate due to emergence of multidrug resistant (MDR) nosocomial infections. We report the draft genome sequence of P. aeruginosa strain VRFPA09, a human bloodstream isolate, phenotypically proven as MDR strain. Whole genome sequencing on VRFPA09, deciphered betalactamase encoding blav(eb-1) and bla(OXA-10) genes and mu...

Breast cancer is commonly treated by various combinations of surgery, radiation therapy, chemotherapy and hormone therapy. Most cancers either are increasingly resistant to any initial treatment or acquire resistance to a broad spectrum of anticancer drugs over time. Combination of more than one drug or combination with multidrug resistance (MDR) modifiers will possibly support the efficiency o...

Background: Multidrug resistance (MDR) is known to defeat most chemotherapies as one of the main anticancer strategies. The role of overexpression/overactivation of ABC transporters, especially P-glycoprotein (P-gp), in the development of chemotherapy has long been demonstrated. Salinispora is a marine actinomycete genus known for the production of novel bioactive metabolites. Methods: In this...
