The review of pathogenic mechanism of Aeromonas hydrophila and action of tetracycline against it in aquatic animals
Aeromonas hydrophila is one of common bacterial disease in aquatic animals and its outbreak cause to decrease of aquatic production. Aeromonas disease is due to a protein toxin, aerolysin that exported by Aeromonas hydrophila. This protein toxin forms channels on target cells membrane, disrupting normal activities and cause to destruction and death of them. Aerolysin toxic protein is secreted b...
متن کاملOptimization of EnBase Fed-Batch Cultivation to Improve Soluble Fraction Ratio of α-Luffin Ribosome Inactivating Protein
Background: The increase of the protein expression via ribosomal manipulation is one of the suggested cellular mechanisms involved in EnBase fed-batch mode of cultivation. However, this system has not been implemented for cytotoxic proteins.Objectives: Here, the expression pattern of α-Luffin, a ribosome inactivation protein (RIP) with an innate toxicity,...
متن کاملSpecific Inhibition of the Expression of the Promyelocytic Leukemia (PML) Protein by Anti-Sense Oligonucleotides
In the present study, using anti-sense oligonucleotides the inhibition of expression of the PML protein hasbeen investigated. The anti-sense oligonucleotides were designed against the translation initiation site ofthe PML gene, and their effects were investigated on cellular growth and DNA synthesis. Incubation of normalhuman fibroblast cells with the anti-sense oligonucleotid...
متن کاملRoles of the mammalian target of rapamycin, mTOR, in controlling ribosome biogenesis and protein synthesis.
mTORC1 (mammalian target of rapamycin complex 1) is controlled by diverse signals (e.g. hormones, growth factors, nutrients and cellular energy status) and regulates a range of processes including anabolic metabolism, cell growth and cell division. We have studied the impact of inhibiting mTOR on protein synthesis in human cells. Partial inhibition of mTORC1 by rapamycin has only a limited impa...
متن کاملEffects of dihydrostreptomycin on ribosome function in vivo: lack of correlation between changes in ribosome patterns and growth.
In vivo treatment of susceptible Escherichia coli cultures with low concentrations of dihydrostreptomycin leads to a decline in polysomes and a corresponding increase in 70S particles which behave as run-off ribosomes, as well as free 30S and 50S subunits. We have examined the timing and extent of these effects on ribosomes and compared them to the effects of this antibiotic on growth and prote...
متن کامل[Inhibition of protein synthesis by antibiotics].
Protein synthesis is a complex, multi-step process involving many enzymes as well as conformational alignment. However, the majority of antibiotics that block bacterial protein synthesis interfere with the processes at the 30S subunit or 50S subunit of the 70S bacterial ribosome. The aminoacyltRNA synthetases that activate each amino acid required for peptide synthesis are not antibiotic target...
