Abstract

Colorectal Cancer (CRC) significantly contributes to global cancer-related mortality and morbidity. Callyspongia siphonella (Callyspongia sp.), a Red Sea sponge, has shown promising activity as an anticancer extract and a source of anticancer-active compounds. This study sought to determine the effects of Callyspongia siphonella and its metabolites on HCT-116 colon cancer cells. Cell viability assays showed that Callyspongia sp. inhibited in a dose-dependent manner, the growth of HCT-116 cell lines with IC50 values of 64.8±17 ug/ml on 2D culture and 141.1±6.8 ug/ml on 3D culture. The purified compounds Sipholenol-A and Sipholenone-A have an IC50 of 48.9±2.2 uM and 47.1±1.2 uM respectively. Following Callyspongia sp. treatment of HCT-116, cell cycle analysis showed arrest at G2/M.flow cytometry analysis showed an increase in total apoptosis due to Callyspongia sp treatment. Moreover, mitochondria membrane potential has been reported to be depolarized due to Callyspongia sp. which is an extra sign of apoptosis. Further investigations are needed to explain the particular underlying mechanisms of Callyspongia sp. extract and its metabolites Sipholenol-A and Sipholenone-A to explore their therapeutic potential in treating colon cancer.
