Lung cancer is the primary malignancy of the lung and is the leading cause of cancer‑associated mortality in China. Multidrug resistance (MDR) is an essential aspect of lung cancer treatment failure and a popular topic of investigation in tumor studies. Previous studies have demonstrated that soluble resistance‑related calcium‑binding protein (Sorcin) is involved in the MDR of various types of ...
Acquired multidrug resistance is a major obstacle to a cure for small cell lung cancer (SCLC). Overexpression of the MDR1 gene occurs infrequently in multidrug-resistant SCLC cell lines. The multidrug resistance protein (MRP) can confer multidrug resistance, but its role in clinically acquired drug resistance is unknown. The purpose of this study was to measure expression of MRP and MDR1 mRNA i...
Abstract Background: Efflux systems are components of the bacterial membrane that play a role in homeostasis of the cell and extrusion of toxic compounds. Efflux pumps of the resistance nodulation cell division (RND) superfamily, confer multidrug resistance to their host when over-expressed. One of the RND efflux systems, is AdeABC which have been characterized for A. baumannii. Another pump be...
Multidrug efflux pumps and antimicrobial resistance in Pseudomonas aeruginosa and related organisms.
Pseudomonas aeruginosa is an opportunistic human pathogen characterized by an innate resistance to multiple antimicrobial agents. A major contribution to this intrinsic multidrug resistance is provided by a number of broadly-specific multidrug efflux systems, including MexAB-OprM and MexXY-OprM. In addition, these and two additional tripartite efflux systems, MexCD-OprJ and MexEF-OprN, promote ...
We have generated rat and murine monoclonal antibodies against multidrug resistance-associated protein (MRP), a M(r) 180,000-195,000 membrane glycoprotein involved in a non-P-glycoprotein multidrug resistance of human tumor cells. The antibodies were raised against two different segments of MRP and found to be suitable for protein blot analyses, immunohistochemical and cytochemical studies, as ...
elevated expression of the drug efflux transporter abcg2 seems to correlate with multidrug resistance of cancer cells. specific cox-2 inhibitor celecoxib has been shown to enhance the sensitivity of cancer cells to anticancer drugs. to clarify whether abcg2 inhibition is involved in the sensitizing effect of celecoxib, we investigated whether the expression of abcg2 in breast cancer cell lines ...
1885 remained otherwise well until January, 1996, when he developed recurrent biliary stricturing with jaundice and worsening diarrhoea. Trough cyclosporin concentrations were considered sub-therapeutic at 60 ng/mL and so he was converted to Neoral therapy at the same dose. Several 12-h trough whole blood cyclosporin levels were taken over the following 2 months, and did not exceed 125 ng/mL. I...
The overexpression of multidrug resistance protein 1 (MDR1) and multidrug resistance protein 1 (MRP1) gene products is a major cause of multidrug resistance in cancer cells. A recent study suggested that disulfiram, a drug used to treat alcoholism, might act as a modulator of P-glycoprotein. In this study, we investigated the molecular and chemical basis of disulfiram as a multidrug resistance ...
