Moreover, although we mainly explored the roles of CPT1C in CRC from the perspective of prognosis prediction and biological functions, we could not exclude the possibility that CPT1A and CPT1B might also participate in tumor phenotype modulation because some previous studies have reported that CPT1A and CPT1B could promote cell invasion and proliferation in other malignancies [35,36]. This evidence concerns the gene CPT1B and colorectal carcinoma.
