Here we demonstrated that Galectin-3 protein level was frequently up-regulated in
colorectal cancer (CRC) cells and tissues. Galectin-3 up-regulation correlated
with CRC progression and predicted a shorter overall survival of CRC patients.
Galectin-3 overexpression attenuated the chemo-sensitivity of cancer cells, but
enhanced the potential invasiveness. To explore the mechanism for Galectin-3
dysregulation, we found that miR-128 level was frequently down-regulated in CRC
and negatively correlated with Galectin-3 level. Using bioinformatics analysis
and experimental validation, we showed that miR-128 could directly target
Galectin-3 to repress its protein level. MiR-128 decrease associated with CRC
progression and predicted a worse overall survival of CRC patients. Ectopic
miR-128 expression enhanced the chemo-sensitivity of CRC cells in vitro and in
vivo, and inhibited the potential invasiveness. Galectin-3 expression impaired
the cancer suppressive effects of miR-128. These data highlighted the role of
miR-128/Galectin-3 axis in colorectal cancer.
