Abstract:
MicroRNAs play important roles in carcinogenesis by negatively regulating the expression of target genes. Here we explore the biological function of miR-155 and the underlying mechanism in colorectal carcinoma. We validate, for the first time, that E2F2 is a direct target of miR-155 using western blot and a luciferase reporter assay and that miR-155 regulates the proliferation and cell cycle of colorectal carcinoma cells by targeting E2F2 using siRNA technology. We also found, for the first, time that E2F2 acts as a tumor suppressor in colorectal carcinoma. Overall, miR-155 plays an important role in colorectal carcinoma tumorigenesis by negative regulation of its targets including E2F2 and may be a potential therapeutic target for colorectal carcinoma treatment.
