In our research, we investigated the chemosensitivity of CpG ODN in HepG2 human hepatoma cells, the HepG2 cells have been cultured in vitro, and the cell proliferation, apop tosis, cell cycle as well as the antiapoptotic things were tested. selleck Bortezomib The attainable molecular mechanisms have been investigated. Results CpG ODN in bination with five FU Rocuronium decreases cell viability in HepG2 cells Preceding studies showed that TLR9 is expressed in hu guy lung cancer A549 cells and human hepatoma HepG2 cells TLR9 expression and perform in BEL 7402 cells, belong to the human hepatoma cell lines, are certainly not reported. The expression of functional lively TLR9 in human malignant tumors might possibly have an effect on treatment method ap proaches using CpG ODN. To evaluate the cytotoxicity of CpG ODN on HepG2 cells, BEL 7402 cells and A549 cells, cells had been incubated with five gradient concentra tion ranging from 0. 25 to 25 uM for 48 h.
The viability was established utilizing CellTiter 96Aqueous A single Solu tion Cell Proliferation Assay The results showed that CpG ODN substantially decreased the viability of HepG2 cells within a dose dependent method. Nevertheless, CpG ODN had no impact within the viability of BEL 7402 cells and A549 cells These findings indi cated that HepG2 cells, but not BEL 7402 cells and A549 cells, are delicate to CpG ODN. Taking into ac count the high inhibition of CpG ODN on HepG2 cells, and it had been chosen and utilized in the subsequent experiments. could promote cell proliferation and survival in human hepatocellular carcinomas. Herein, we pared the cytotoxicity of non CpG ODN,CpG ODN and ODN M362 towards HepG2 cells, cells have been taken care of with non CpG ODN, CpG ODN or ODN M362 at 5 concentra tion ranging from 0. 25 to 25 uM for the indicated time. The outcome showed that CpG ODN substantially decreased the viability of HepG2 cells in time and dose dependent manner Yet, non CpG ODN and ODN M362 didnt have direct cytotoxicity toward HepG2 cells The results showed that CpG ODN, but not ODN M362 and non CpG ODN, can dir ectly mediate cytotoxicity towards HepG2 cells.
