Aim: In this paper effect of combinational usage of calprotectin and etoposide on AGS cell line is studied.
Background: Application of combined toxic agents such as etoposide and cicplatin are commonly used for chemotherapy purposes. As a matter of fact, calprotectin and etoposide were both applied on human gastric adenocarcinoma cell line (AGS) as antitumor agents. Both calprotectin and etoposide are topo II inhibitor. Etoposide is a lipophilic agent that can easily transport from membrane while calprotectin active intracellular pathway, probably by membrane surface receptor.
Patients and methods: Calprotectin was purified from human neutrophil by chromatography methods. The human gastric adenocarcinoma cell line was exposed to different concentrations and combinations of calprotectin and etoposide. MTT assay was applied for evaluation of cytotoxicity assay.
Results: Viability of AGS cell line was reduced in high dosages of calprotectin and etposide. In fact, overnight incubation of these two agents together has been shown less effective than individual usage.
Conclusion: The result indicates that, the combination of both calprotectin and etoposide is considerably less cytotoxic on gastric cancer cells (AGS) than applying individually.
