Effect extraction of alkaloids from alge Chlorococcum humicola in cell line and gene expression

The first assay study effect of extract on lymphocyte division in human blood and this suggest that this extract for Chlorococcum humicola alge lead to capture cell division of lymphoid cell in human blood at mitosis stage at different levels. This block was increased with increase the concentrations, the percentage of blocked cells 16.50 to 98.30% for concentrations 50-800 µg\mL. The second assay including effect of extract on growth of tumor cell lines MCSF7, Hela RD and normal cell line was done by using cytotoxic assay. The findings demonstrated that the cytotoxicity of the extract varied depending on cell type and concentration in different cell lines. With higher extract concentrations, tumor cell line inhibition activity increased. The higher inhibition rate in MCSF7 cell line was 99.54% at the concentration 800 µg\mL and lower inhibition rate was 30.07% in concentration 50 µg\mL, while for Hela the highest inhibition rate was 90.31% in concentration 800 µg\mL and lower inhibition rate was 22.19% in concentration 50 g\mL, the highest inhibition rate for RD cell line was 10.11 % in 800 µg\mL and lower inhibition rate was 0.0 % in 50 g\mL and 9.90 in 400 µg\mL. The all results showed that crude alkaloid extract of Chlorococcum humicola alge was induced apoptosis by mitochondrial intrinsic pathway after 24 h of exposure.
