Abstract
Background/aim:
Colon cancer is one of the most common cancers. Treatment success and survival rates are not high enough with current approaches. Therefore, there is a need to develop new agents and treatment methods. Boric acid is the most frequently observed form of boron. Some epidemiological data suggest that environmental exposure to boric acid reduces the incidence of prostate cancer in men, cervical and lung cancers in women. Experimental studies show, boric acid reduces cell proliferation and stimulates apoptosis in some prostate, melanoma, breast cancer cell lines. In this study, it was investigated whether boric acid could be a new candidate molecule that could be used in the treatment of colon cancer.
Materials and methods:
The effects of boric acid on human colon adenocarcinoma cell line SW-480 were investigated with BrdU, TUNEL, Caspase-3, and AIF immunohistochemical studies in both 2D and 3D culture systems. In addition, a qRT-PCR study was carried out to determine the expression changes in key genes that take part in apoptosis.
Results:
We observed that boric acid suppresses cell proliferation and induces apoptosis both in 2D and 3D culture conditions. In addition, as a result of qRt-PCR studies, it was revealed that the observed apoptotic process was related to the TNF signaling pathway.
Conclusion:
Boric acid can be considered as a potential anti-cancer agent candidate for colon cancer treatment.
