Cell death induced by Morarah and Khaltita in hepatoma cancer cells [Huh-7]

ABSTRACT

To compare the combined and isolated growth inhibitory effects of Morarah and Khaltita [herbs] on hepatoma cell lines [Huh-7], through induction of apoptosis or necrosis. Comparative controlled in-vitro study. The Molecular Biology Laboratory, The Aga Khan University, Karachi, from June to December 2006. The growth of hepatoma cell lines [Huh-7] was checked by adding Khaltita and Morarah to the cells before culture in a 24 well plate. Six wells were selected and labeled for each of the four variables [controls, Khaltita, Morarah and mixture]. After 2 days, cells were studied under an inverted phase contrast microscope and fields were recorded. Approximately four fields per slide of higher intensity were selected randomly to determine the dead cell density, and the procedure was repeated 10 or more times. Frequency and percentages were calculated for dead or alive cells in controls, Morarah, Khaltita and their mixture. Chi-square was used to compare the qualitative variables. P-values < 0.05 were considered significant. Morarah and Khaltita were found to induce statistically significant [p < 0.001] cell death in hepatoma cell lines [Huh-7]. At a magnification of 40x, the controls showed 1% dead cells compared to 91% in Morarah, 83% in Khaltita and 73% in combined mixture of Khaltita and Morarah. At magnification of 20x, the controls showed 4% dead cells compared to 44% in Morarah, 47% in Khaltita and 49% in the combined mixture of Khaltita and Morarah. Morarah and Khaltita induced cell death in cultured hepatoma cells [Huh-7]
