Abstract

Colorectal cancer (CRC) is one of the major causes of death across the world and incidence rate of CRC increasing alarmingly each passing year. Diet, genomic anomalies, inflammation and deregulated signaling pathways are among the major causes of CRC. Because of numerous side effects of CRC therapies available now, researchers all over the world looking for alternative treatment/preventive strategy with lesser/no side effects. Olive oil which is part of Mediterranean diet contains numerous phenolic compounds that fight against free radicals and inflammation and also well-known for protective role against CRC. The current review focused on the recent evidences where olive oil and its phenolic compounds such as Hydroxytyrosol, Oleuropein and Oleocanthal showed activities against CRC as well to analyze the cellular and molecular signaling mechanism through which these compounds act on. These compounds shown to combat CRC by reducing proliferation, migration, invasion, and angiogenesis through regulation of numerous signaling pathways including MAPK pathway, PI3K-Akt pathway, and Wnt/β-catenin pathway etc. and at the same time induce apoptosis in different CRC model. However, further research is an absolute necessity to establish these compounds as nutritional supplements and develop therapeutic strategy in CRC.
