The appropriately transformed bacterial colonies were grown in LB broth containing 100g/ml ampicillin until an OD600nm was 0.5; then expressions of the recombinant proteins were induced by adding 1mM isopropyl--D-1-thiogalactopyranoside (IPTG) to individual cultures at 37C for 4h. Thereafter, the bacterial cells were harvested by centrifugation and lysed using BugBuster Protein Extraction Reagent (Novagen, Merck KGaA, Darmstadt, Germany) supplemented with 10 microliters of Lysonase Bioprocessing Reagent (Novagen) per gram of bacterial cell pellet. It is the archaeal and eukaryotic counterpart of bacterial EF-G. Diphthine synthase is an enzyme that in humans is encoded by the DPH5 gene. The toxicity of PE-anti-TAC was enhanced 50-fold in the presence of human adenovirus type II and was reduced to control levels by adding excess anti-TAC antibody.

In this study, human single-chain antibodies (HuscFvs) that bound to P. aeruginosa exotoxin A (ETA) were generated by phage display technology using recombinant ETA, ETA-subdomains and the synthetic peptide of the ETA-catalytic site as baits for selecting ETA-bound-phages from the human-scFv phage display library. Care Med. Both targeted toxins were more than 600 to 140,000-fold more cytotoxic than the EGFR inhibitor erlotinib. Wahab, A.

The amounts of casp3 and p53 were normalized to the internal control, i.e., GAPDH. In the early stages of an infection, the number of bacterial pathogens and hence the concentration of quorum-sensing molecules is low. 2022 Dec 13;23(24):15820. doi: 10.3390/ijms232415820.

Real-time RT-PCR was performed on KAPA SYBR FAST qPCR (Kapa Biosystems, Cape Town, South Africa). Pseudomonas aeruginosa produces a myriad of virulence factors to cause fatal diseases in humans. Binding of HuscFv-display phages to the immobilized antigens were allowed at room temperature for 1h on a rocking platform. (C) Scanning electron microscopic appearances of ETA-exposed HeLa cells after treatment with ETA-bound HuscFvs, control HuscFv (Irre) and medium alone. The results of Annexin V/PI staining for apoptotic cells after treatment of the 3nM ETA-exposed cells with different concentrations of individual HuscFvs (60, 150 and 300nM) are shown in Table1. & Andersson, Y. Immunotoxins: a promising treatment modality for metastatic melanoma? Google Scholar. doi: 10.1001/jama.2017.7248. Scientific Reports (Sci Rep) Control HuscFv (300nM) showed averaged percent apoptotic cells at 23.8 0.52%, which did not differ significantly from the ETA-exposed cells in medium alone (25.08 4.51%). HuscFv-E44 was predicted to use VL-CDR2 and VL-FR3 to interact with Q310, R313, and A317 of ETA-2 (translocation domain); this binding should not be involved in the HuscFv-mediated-neutralization of ETA cytotoxicity. An exotoxin is a toxin secreted by bacteria. Toxins are molecules that cause damage to host cells and tissues, leading to disease. This conjugate was toxic to HUT-102 cells, a cell line that expresses the TCGF receptor, but was nontoxic for MOLT-4 cells, a receptor-negative line. Concentration- and time-dependent killing of PCa cells was found with IC50 values after 48 and 72 h in the low nanomolar or picomolar range based on the induction of apoptosis. Among many species of genus bacillus, most of them will not cause disease, but a few species are important factors in human diseases. The pathogenic bacterium Pseudomonas aeruginosa has the ability to cause severe acute and chronic infections in humans. I. Elongation factors are a set of proteins that function at the ribosome, during protein synthesis, to facilitate translational elongation from the formation of the first to the last peptide bond of a growing polypeptide. Immunotherapy in prostate cancer. Nevertheless, the possibility also exists that the effective HuscFvs might inhibit/interfere with some other steps of ETA-mediated cellular intoxication, either by steric hindrance of-, or direct binding to-, the toxin critical residues and in effect causing interference with the respective toxin bioactivity(-ies) such as receptor binding, clathrin-dependent cellular internalization, endosomal exit, retrograde transportation of the toxin through the Golgi network, or EF2-ADP-ribosylation.
