RESUMO
@#Circular RNAs (circRNAs) are a class of non-coding RNAs formed by covalently closed loops through backsplicing. From previous studies, RNA was found to be involved in the development and formation of colorectal cancer. By emphasizing on the true function of circRNAs through focusing on its biogenesis, roles in disease treatment and roles as biomarkers, we are able to utilize circRNAs as therapy for cancer. Cancer is a chronic disease that contributes to high mortality worldwide. Colorectal cancer is one of the most common cancer in the world and in Malaysia in general. The incidence and mortality rates of colorectal cancer worldwide show a drastic and alarming increase. Colorectal cancer occurs due to mutations from certain genes involved in proliferation regulation, cell survival and cell death. This article aims to discuss the role and importance of Circular RNA in colorectal cancer. By identifying the true function of circRNAs, it can help us to develop our understanding on the real biological roles of circRNAs in colorectal cancer.
