Core Tip

Core tip: Mechanistic target of rapamycin (mTOR) pathway serves as a central regulating axis that coordinates cell growth and proliferation. Single-agent mTOR inhibition therapy, however, has provided only limited therapeutic efficacy towards colorectal cancer. Blocking compensatory pathways and multiple feedback loops is considered the challenge. Combination regimens are being intensively tested in clinic. This review summarizes extensive studies describing crosstalk between mTOR pathway and major oncogenic pathways contributing to colorectal cancer development and novel combinational strategies targeting the mTOR pathway in treating colorectal cancer are also introduced.
