one of the major complications in cancer chemotherapy is the development of resistance, and cisplatin, as one of the important medicines in treatment regimens of different cancers is not excluded. one of the most described cellular defense mechanisms involved in resistance is glutathione (gsh) and in this study, the effects of cisplatin on the total intracellular gsh level (gshi) in some sensit...
Toll-like receptors (TLRs) are a primary surveillance system for the detectionof pathogens and are crucial to the activationof host defense. TLR7 and TLR8 sense single-stranded RNA from viruses or host ribonucleoproteins and synthetic imidazoquinolines such as R848, whereas TLR9 senses unmethylated CpG motifs in viral and bacterial DNA and in host DNA. Here we report the endogenous interaction ...
The dramatic responses tumors display to targeted therapies are limited by acquired or pre-existing mechanisms of therapy resistance. We recently discovered that androgen receptor blockade by the anti-androgen enzalutamide paradoxically enhanced metastasis and that these pro-metastatic effects were mediated by the chemoattractant CCL2. CCL2 is regulated by TNF, which is negatively regulated by ...
objective(s): development of molecules that specifically recognize cancer cells is one of the major areas in cancer research. human epidermal growth factor receptor 2 (her2) is specifically expressed on the surface of breast cancer cells. her2 is associated with an aggressive phenotype and poor prognosis. in this study we aimed to isolate rna aptamers that specifically bind to her2 overexpressi...
BACKGROUND Cigarette smoke suppresses innate immunity, making smokers more susceptible to infection. The NLRP3 inflammasome is a multi-protein complex that releases interleukin (IL) -1β and IL -18. These cytokines are critical for a timely host response to pathogens. Whether cigarette smoke affects NLRP3 protein levels, and its ability to form an inflammasome, is not known. METHODS AND RESULT...
The development of resistance to chemotherapeutic agents, such as Doxorubicin (DOX) and cytarabine (AraC), is one the greatest challenges successful treatment Acute Myeloid Leukemia (AML). Such acquisition often underlined by a metabolic reprogramming that can provide therapeutic opportunity, it lead emergence vulnerabilities dependencies be exploited targets against resistant cells. In this re...
the influenza viruses are major etiologic agents of human respiratory infections, and inflict a sizable health and economic burden. this study examines the antiinfluenza virus activity of hydroalcoholic extract of olive leaves (olhe). olive leaves were collected from gardens around the city of shiraz, characterized, dried, ground to powder, and its hydroalcoholic extract was prepared. the influ...
background: rna interference (rnai) is the mechanism of gene silencing-mediated messenger rna degradation by small interference rna (sirna), which becomes a powerful tool for in vivo research, especially in the areas of cancer. in this research, the potential use of an expression vector as a specific sirna producing tool for silencing of bcr-abl in k562 cell line has been investigated. methods:...
expression of receptor tyrosine kinase ror1 in a wide variety of cancers has emerged as a new era focusing on targeting this receptor in cancer therapy. our preliminary re-sults indicate the presence of a truncated transcript of ror1 in tumor cells. the trun-cated ror1 encompasses extracellular and transmembrane domains, lacking catalytic kinase domain (ror1-ecd). as enzyme activity is highly d...
Shiga toxins (Stxs) are bacterial virulence factors produced by Shigella dysenteriae serotype 1 and Escherichia coli strains. Stxs are critical factors for the development of diseases such as severe bloody diarrhea and hemolytic uremic syndrome. Additionally, Stxs trigger the secretion of pro- inflammatory cytokines and chemokines, particularly in monocytes or macrophages. The inflammatory cyto...
