Abstract:
Rectal cancer is considered a major health issue in several countries that present advanced and metastatic stages and a limited response to standard treatments. Though the antineoplasic activity of cannabinoids has been documented in several studies, scarce information is available about the effect of these agents in cell lines of rectal cancer. In this work, we explored the antiproliferative effects of cannabinoid receptor agonists in rectal tumor cells. The effects of the three agonists anandamide, methanandamide and CP55940 were evaluated in the SW837 rectal tumor cell line. The three agents tested showed time and concentration dependent effects on cell viability, induction of cell death and morphological changes. The three agonists were effective to induce late apoptosis and necrosis and internucleosomal DNA fragmentation. In addition, we evaluated for the first time the patterns of CB1 and CB2 cannabinoid receptor expression in SW837. Though some differences in their effects were found, our data support the concept that these agents mostly share common antiproliferative/cell death mechanisms. Our results also confirm the antineoplasic potential of cannabinoids receptor agonists against rectal cancer, and suggest the design of cannabinoid based coadjutant therapies at the clinical level.
