Long non-coding RNAs (lncRNAs) regulate a series of biological processes, and their anomalous expression exerts critical roles in progression of multiple malignancies, including colorectal cancer (CRC). The present study was designed to provide new ideas and perspectives for the role of lncRNA MCF2L-AS1 and disclose the underlying mechanism in CRC. Herein, we observed that MCF2L-AS1 expression was enriched in CRC tissues and cell lines. Additionally, silencing of MCF2L-AS1 dramatically impeded cell proliferation, invasion and migration capacities of CRC, and distinctly attenuated the expression of invasion associated targets MMP-2 and MMP-9. Moreover, depletion of MCF2L-AS1 apparently restricted the glucose consumption and lactate production, and downregulated GLUT1 and LDHA expression. More importantly, we predicted and verified that MCF2L-AS1 acted as a molecular sponge for miR-874-3p and inversely regulated miR-874-3p expression. Interesting, FOXM1 was identified as direct target of miR-874-3p, and positively modulated by MCF2L-AS1 through sponging miR-874-3p. Mechanistically, MCF2L-AS1 accelerated cell proliferation, invasion and glycolysis through competitively binding to miR-874-3p, leading to enhance FOXM1 expression. Collectively, these outcomes highlighted that MCF2L-AS1 acted as a motivator by modulating the miR-874-3p/FOXM1 axis, thereby aggravating tumorigenesis and glycolysis progress of CRC, disclosing that MCF2L-AS1 may serve as a valuable and promising therapeutic strategy for CRC.
