study of kir expression and hla ligands in cd56+ lymphocytes of drug resistant tuberculosis patients
analysis of receptor–ligand interactions in the context of diseases necessitates to understand how hla–kir genotypes function in diseases. although cd56+ lymphocytes are derived from multiple lineages, they share a functional association with immunosurviellance and antimicrobial responses. the present study aimed to determine whether kir phenotype in cd56 lymphocytes and corresponding...
Multiple drug resistance (MDR) is considered a major challenge in the clinical treatment of non-small cell lung cancer (NSCLC). Both nitric oxide synthase (iNOS) and Wnt signaling pathway participate in the regulation of drug resistance, but the interaction between them remains unclear. In the present study, we detected the activation of Wnt/β-catenin signaling in iNOS-induced drug-resistant lu...
A gemcitabine (GEM)-resistant human pancreatic cancer cell line (PANC-1RG7) was established in vitro by gradually increasing GEM concentrations and cloning cell cultures to develop a cellular model of acquired drug resistance studies. We found that PANC-1RG7 cells exhibited significantly different morphological characteristics from parental cells. PANC-1RG7 cells grew slowly (p<0.05), yet the c...
background: integrons are the major reasons of multidrug resistance (mdr) among enteropathogenic bacteria. occurrence of horizontal gene transfer between integron-carrying microorganisms and other enteric bacteria may increase the rate of emergence of integron-associated antibiotic resistance. objectives: the objective of this study was to investigate class 1 integrons among members of enteropa...
Colorectal cancer (CRC) is one of the most common reasons for cancer-associated mortality worldwide. The present study aimed to investigate the drug resistance mechanism of the oxaliplatin (OXA)-resistant HT-29 cell line (HT-29/L-OHP) and examine the expression of lysosome-associated protein transmembrane 4β (LAPTM4β), a drug resistance-associated gene. In the present study, a drug concentratio...
عفونت و تهاجم ارگانیسم های انگلی به بدن، عامل اصلی بیماری و مرگ انسانها از آغاز بشریت بوده است . در حقیقت بسیاری از اشکال حیات بدون غلبه بر ارگانیسم های زنده دیگر، قادر به ادامه زندگی نخواهند بود. انسانها معمولا مستعد تهاجم ارگانیسم های کوچکتری مانند کرمها، آمیب ها، قارچها، باکتریها و ویروسها هستند. این عوامل مکان خاصی را در بدن انتخاب کرده، مواد ضروری لازم برای حیات و تکثیر خود را دریافت نموده...
Acinetobacter baumannii is a common causative agent of hospital-acquired infections and a leading cause of infection in burns patients. Carbapenem-resistant A. baumannii is considered a major public-health threat and has been identified by the World Health Organization as the top priority organism requiring new antimicrobials. The most common mechanism for carbapenem resistance in A. baumannii ...
Human hepatoma cells may represent a valuable alternative to the use of human hepatocytes for studying hepatic drug transporters, which is now a regulatory issue during drug development. In the present work, we have characterized hepatic drug transporter expression, activity and regulation in human hepatoma HuH-7 cells, in order to determine the potential relevance of these cells for drug trans...
We present a new approach for pathogen surveillance we call Geogenomics. Geogenomics examines the geographic distribution of the genomes of pathogens, with a particular emphasis on those mutations that give rise to drug resistance. We engineered a new web system called Geogenomic Mutational Atlas of Pathogens (GoMAP) that enables investigation of the global distribution of individual drug resis...
