Background & Aims: Hepatocellular carcinoma remains often refractory to classic therapies. Therefore, the search for new natural compounds with minimal toxicity is of particular interest in treatment of liver cancer. In this context, it has been shown that 2-methyl-3-pentyl-6-methoxyprodiginine isolated from cell wall of Serratia marcescens has powerful growth inhibitory effects against different kinds of cancer cells. In this study, we investigated the anti-proliferative effect of prodigiosin on the human hepatocellular carcinoma HepG2 cells on a dose-response and time-course basis.

Materials & Methods: Malignant cells were treated with various concentrations of prodigiosin (100, 200, 400 and 600 nM) and incubated for 24 to 72 h. After treatments, proliferation-rates were determined by MTT assay. Following 48 h treatments with indicated concentrations of prodigiosin, cell number and apoptotic rates were also measured by hemocytometer and flow cytometer respectively.

Results: Treatment of cells with increasing concentrations of prodigiosin significantly decreased proliferation-rates in a dose-and time-dependent manner compared to untreated cells. Specifically, Following 72 h treatments with 100, 200, 400 and 600 nM prodigiosin proliferation-rates were found to be %44 ± %2, %33 ± %4, %27 ± %3 and 27% ± %5 for indicated concentrations of prodigiosin respectively. We also found that the cell numbers were decreased in a dose-dependent manner. Specifically, 48 h treatment with 600 nM prodigiosin resulted in 77% decrease in cell number compared to untreated cells. An increase in the number of apoptotic cells (late), ranging from 37 to 97.4 %, was also observed with increasing prodigiosin concentrations.

Conclusion: Prodigiosin decreases proliferation of hepatocellular carcinoma cells with induction of apoptosis in these cells. Therefore, this compound may provide a powerful growth inhibitory agent on proliferation of hepatocellular carcinoma cells.
