Antiproliferative effects of porins extracted from Klebsiella pneumoniae on HL-60, NIH/3T3 and Human foreskin fibroblast cell (HFFC) lines measured by ELISA method
View through CrossRef
Approximately, 50% of the dry mass of the outer membrane of gram-negative bacteria consists of proteins, and more than 20 immunochemically distinct proteins (termed outer membrane proteins [OMPs]) have been identified. An identified local strain of Klebsiella pneumoniae was used as a primary source for the isolation and purification of porins. Multiple concentrations of purified porins (5, 10, 15, 20, 25) g/ml were incubated with three different cell lines for (24, 72 , 120) hrs, after the end of the incubation periods, the cells were treated with Cell proliferation ELISA, BrdU (colorimetric) kit to evaluate the antiproliferative effects of porins. The results revealed that porins are potent antiproliferative agent in a time and concentration dependent manner and thus could greatly affect prokaryote-eukaryote interaction as well as the whole inflammatory process resulted after infection with gram negative bacteria.
