The aim of the present study was to investigate the reversal effect and its related mechanism of Ginkgo biloba exocarp extracts (GBEEs) in obtained multidrug resistance (MDR) of mice S180 tumor cells in vitro and in vivo. In order to simulate the clinical PFC [cis-dichlorodiamineplatinum, cisplatin (DDP) + fluorouracil (FU), FU+cyclophosphamide and cyclophosphamide] scheme, a gradually increasi...
The histone-like protein H-NS is a major component of the bacterial nucleoid and plays a crucial role in global gene regulation of enteric bacteria. It is known that the expression of a variety of genes is repressed by H-NS, and mutations in hns result in various phenotypes, but the role of H-NS in the drug resistance of Escherichia coli has not been known. Here we present data showing that H-N...
OBJECTIVE To determine whether curcumin reverses the multidrug resistance of human colon cancer cells in vitro and in vivo. METHODS In a vincristine-resistant cell line of human colon cancer, the cell viability of curcumin-treated cells was determined using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Rhodamine123 efflux was evaluated to detect P-glycoprotein transp...
BACKGROUND/AIM Altered redox status has been reported to play a significant role in the development of multidrug resistance (MDR) in leukemia cells. Human biliverdin reductase (hBVR) has been recently identified as a major cytoprotectant; however, its role in MDR has not been yet investigated. In the present study we evaluated the possible role of hBVR in MDR development in the human HL60 leuke...
OBJECTIVES To determine the complete nucleotide sequence of the multidrug resistance IncA/C plasmid pR55 from a clinical Klebsiella pneumoniae strain that was isolated from a urinary tract infection in 1969 in a French hospital and compare it with those of contemporary emerging IncA/C plasmids. METHODS The plasmid was purified and sequenced using a 454 sequencing approach. After draft assembl...
One of the major problems in treatment of leukemias is multidrug resistance, which is already present at diagnosis or develops after chemotherapy. The gene expression levels of multidrug resistance resistance 1 (MDR1), breast cancer resistance protein (BCRP) and lung resistance-resistance protein (LRP) were evaluated in blood samples of 20 CLL and 24 CML patients using RT-PCR. MDR1, BCRP and LR...
Multidrug resistance is recognized as the key factor of many anticancer drugs invalidity. Anticancer treatments such as chemotherapy or radiation must hit their cellular targets and then cause cellular alteration or damage. However, in most cases the damage inflicted by the anticancer agent triggers apoptosis 1. Acute lymphoblastic leukemia (ALL) is the most frequently occurring cancer in child...
