Abstrakt: This study aimed to investigate the antimitotic and antiproliferation activities of crude acetone-methanol and aqueous extracts of two marine molluscs commonly found in the Niger Delta region of Nigeria; T.fuscatus and P.aurita , against human cancerous cell lines (DU145, Hep-2, and HCC1395) cell lines in vitro . The antimitotic activity of the extracts was evaluated using Allium cepa root meristematic cells. Antiproliferative activity of the plant extracts against the cancerous cell lines was compared with normal cell line (VeroE6). Doxorubicin was used as a positive control. Gene expression studies using qPCR for the proapoptotic genes, CASP3, CASP8 and P53 were also carried out. The alcohol extract of T.fuscatus (TFAC) exhibited the most promising activity against all the cancer cell lines tested (DU145 IC 50 = 96.48 ± 1.36 μg/ml, HCC 1395 IC 50 = 61.44 ± 2.45 μg/ml, Hep2 IC 50 = 0.52 ± 0.36 μg/ml) and also had the highest selectivity index of 4.94, 7.78 and 921.97 for DU145, HCC 1395 and Hep-2 cells respectively. Furthermore, TFAC was the only extract that significantly upregulated the expression of caspase 3, caspase 8 and P53. Thus, these findings suggest potential exploitation of TFAC as an anticancer agent.
