Two spurge species, Euphorbia resinifera O. Berg and Euphorbia officinarum subsp. echinus (Hook.f. & Coss.) Vindt inhibit colon cancer

Abstract

Colon cancer, a prominent contributor to global cancer-related deaths, prompts the need for innovative treatment strategies. Euphorbia resinifera O. Berg (E. resinifera) and Euphorbia officinarum subsp. echinus Hook. f. & Coss Vindt (E. echinus) and their bee-derived products have been integral to traditional Moroccan medicine due to their potential health benefits. These plants have historical use in addressing various health issues, including cancer. However, their effects against colon cancer remain unclear, and the specific mechanisms underlying their anti-cancer effects lack comprehensive investigation. The study aimed to assess the potential anti-cancer effects of Euphorbia extract on colon cancer cell lines (DLD-1) through various techniques. The apoptosis, migration, and proliferation of DLD-1 cells were measured in DLD-1 cells. In addition, we conducted High-Performance Liquid Chromatography (HPLC) analysis to identify the profile of phenolic compounds present in the studied extracts. The extracts demonstrated inhibition of colon cancer cell migration. E. resinifera flower and E. echinus stem extracts show significant anti-migratory effects. Regarding anti-proliferative activity, E. resinifera flower extract hindered proliferation, whereas E. echinus flower extract exhibited dose-dependent inhibition. Apoptosis assays revealed E. resinifera flower extract inducing early-stage apoptosis and E. echinus flower extract promoting late-stage apoptosis. While apoptotic protein expression indicated, E. resinifera stem and propolis extracts had minimal impact on apoptosis. The findings provide evidence supporting the beneficial effects of E resinifera and E. echinus extracts on colon cancer and exerting anti-cancer properties.
