Effects of methylation agent S-adenosyl-L-methionine on the biological behaviors of colorectal cancer cells
摘要
Abstract
Objective To evaluate the effects of methylation agent S - adenosyl - L - methionine ( SAM ) on the biological behaviors of colorectal cancer ( CRC ) cell lines, SW620 and LoVo. Methods LoVo and SW620 were treated with SAM for 6 days. Cell proliferation and cell cycle were assessed by plate colony formation assay and flow cytometry assay , respectively. Meanwhile, the efficacy of SAM on CRC cell apoptosis was also analyzed by flow cytometry. S - adenosyl -L-homocysteine ( SAH ) -treated cells and mock - treated cells were used as control groups in our study. Results A significant inhibition of cell proliferation was observed in SAM - treated SW620 and LoVo cells as compared with SAH -treated cells ( P <0. 001 ). In addition, a significant reduction of the plate colony formation was also observed in SAM-treated cells as compared with SAH - treated cells and mock - treated cells ( P < 0. 001 ). However, no apoptosis peak was detected in SAM - treated cells. Conclusion Methylation agent SAM can not only inhibit cell proliferation but also result in the arrest of cell cycle. Our study suggests a potential role of SAM in the clinical treatment of CRC.关键词
