Biochemical and Biological Evaluation of an L-Asparaginase from Isolated Escherichia coli MF-107 as an Anti-Tumor Enzyme on MCF7 Cell Line.

Background: One of the most widely used anticancer agents is microbial L-ASNase. Herein, we assessed the biochemical and biological properties of an isolated L-ASNase from a Gram-negative bacteria strain, Escherichia coli MF-107.

Methods: Using garden asparagus, we obtained several bacterial isolates.

Evaluation of Inflammasome Activation in Peripheral Blood Mononuclear Cells of Hemodialysis Treated Patients with Glomerulonephritis.

Recently, it has been found that abnormal activation of inflammasomes, the intracellular multiprotein complexes, plays an important role in the pathogenesis and the development of inflammatory diseases. To determine whether the NOD-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome is involved in chronic inflammatory condition reported in glomerulonephritic- hemodialysis (HD) patients, we investigated the mRNA levels of , , and in human peripheral blood mononuclear cells (PBMCs) collected from 28 glomerulonephritic-HD patients. To confirm the mRNA quantification results, we investigated the IL-1ß content and Caspase 1 activity in serum and PBMC lysates, respectively.

Cell-free extracts of and display antiproliferative and antioxidant activities against HT-29 cell line.

Many beneficial effects of probiotic Lactobacilli on cancer prevention and therapy were previously presented. So finding probiotics with proapoptotic activities is a promising approach for cancer drug discovery. Here, the antiproliferative and antioxidant activities of cell-free extracts of and on HT-29 cell line were evaluated employing MTT and DPPH assays.

Cytotoxic and apoptotic properties of a novel nano-toxin formulation based on biologically synthesized silver nanoparticle loaded with recombinant truncated pseudomonas exotoxin A.

Bacterial toxins have received a great deal of attention in the development of antitumor agents. Currently, these protein toxins were used in the immunotoxins as a cancer therapy strategy. Despite the successful use of immunotoxins, immunotherapy strategies are still expensive and limited to hematologic malignancies.

Cytotoxic and apoptotic properties of silver chloride nanoparticles synthesized using Escherichia coli cell-free supernatant on human breast cancer MCF 7 cell line.

Synthesis of silver and silver based nanoparticles using microorganisms has received profound interest because of obtaining nanoparticles with unique physicochemical and biological properties. In the current study, for the first time, synthesis of silver chloride nanoparticles (AgClNPs) using cell-free supernatant of Escherichia coli culture is reported. Prepared AgClNPs were characterized by EDS, XRD and FESE.

Association between thrombophilia gene polymorphisms and recurrent pregnancy loss risk in the Iranian population.

Unlabelled: Miscarriage is the most common complication in pregnancy. Considering the importance of the problem thrombophilia in pregnant women and its association with recurrent pregnancy loss (RPL), analysis of polymorphisms of genes involved in thrombophilia can be useful. We investigated the frequency and association between ten polymorphisms of seven thrombophilia genes and RPL in an Iranian population.

Evaluation of G2 Citric Acid-Based Dendrimer as an Adjuvant in Veterinary Rabies Vaccine.

For induction of an appropriate immune response, especially in the case of an inactivated vaccine, the use of an adjuvant is crucial. In this study, adjuvanticity effect of G2 dendrimer in veterinary rabies vaccine has been investigated. A nonlinear globular G2 dendrimer comprising citric acid and polyethylene glycol 600 (PEG-600) was synthesized and the toxicity was studied in vitro on the J774A.
