Insights into the Anticancer Mechanisms Modulated by Gamma and Delta Tocotrienols in Colorectal Cancers.
Colorectal cancer (CRC) is a growing concern all over the world. There has been a concerted effort to identify natural bioactive compounds that can be used to prevent or overcome this condition. Tocotrienols (T3s) are a naturally occurring form of vitamin E known for various therapeutic effects, such as anticancer, antioxidant, neuroprotective, and anti-inflammatory activities. The literature evidence suggests that two T3 analogues, ie, gamma (γ)- and delta (δ)-T3, can modulate cancers via several cancer-related signaling pathways. The aim of this review was to compile and analyze the existing literature on the diverse anticancer mechanisms of γT3 and δT3 exhibited in CRC cells, to showcase the anticancer potential of T3s. Medline was searched for research articles on anticancer effects of γT3 and δT3 in CRC published in the past 2 decades. A total of 38 articles (26 cell-based, 9 animal studies, 2 randomized clinical trials, and 1 scoping review) that report anticancer effects of γT3 and δT3 in CRC were identified. The findings reported in those articles indicate that γT3 and δT3 inhibit the proliferation of CRC cells, induce cell cycle arrest and apoptosis, suppress metastasis, and produce synergistic anticancer effects when combined with well-established anticancer agents. There is preliminary evidence that shows that T3s affect telomerase functions and support anticancer immune responses. γT3 and δT3 have the potential for development as anticancer agents.
