The Chemosensitizing Effect of Portulaca oleracea Methanol Extract on Human Colorectal and Lung Cancer Cells Against Irinotecan

Abstract

Cancer is a major health problem and it has been causing great damage in recent years worldwide. Serious side effects of chemotherapeutics used in cancer treatment make natural products valuable. Combined use of chemotherapy drugs and herbal products is an important approach in reducing side effects and revealing a more effective treatment. In this study, the effects of methanolic extract from Portulaca oleracea (POM) alone and in combination with Irinotecan were investigated against human colorectal carcinoma cell line HCT-116 and human lung adenocarcinoma cell line A549. The antiproliferative/anti-colony formation effects were determined using WST-1 assay and clonogenic assay. Cell death detection Elisa assay was employed to exhibite the triggered apoptosis, and quantitative real time polimerase chain reaction (qRT-PCR) was performed to evaluate the mRNA expression of mTOR, Akt and PTEN genes, which are significant modulators of apoptotic and survival pathways. It was determined that 72 h treatment with increasing concentrations of POM (0-1000 mg mL-1) decreased the viability of HCT116 and A549 cells in a dose-dependent manner. Also, POM and Irinotecan exhibited synergistic effects in both cell lines. The combination of POM and Irinotecan suppressed the colony forming capacity of HCT116 and A549 cells by 84% and 79%, respectively. POM also altered mTOR, Akt and PTEN gene expressions in HCT-116 and A549 carcinoma cells, both alone and in combination with Irinotecan. This study shows that the phytotherapeutic effect of P. oleracea needs to be studied more intensively.
