Abstract

Liver-intestine cadherin (LI-cadherin), a novel member of the cadherin family, has been associated with the ability of a tumor to acquire an aggressive phenotype in several types of cancer. However, the exact function of LI-cadherin in the process of tumor invasion and metastasis remains predominantly unknown. To explore the effect of LI-cadherin on the regulation of matrix metalloproteinase-2 (MMP-2), MMP-9 and galectin-3 in LoVo human colorectal cancer cells, a RNA interference technique was applied to suppress the expression of LI‑cadherin. Subsequently, the mRNA levels and activities of MMP-2 and -9 were analyzed by semi-quantitative reverse transcription-polymerase chain reaction and gelatin zymography, respectively. Additionally, the protein expression level of galectin-3 was determined by western blot analysis. The results of the present study demonstrated that short hairpin RNA (shRNA)-silencing of LI-cadherin significantly increased the mRNA levels and activities of MMP‑2 and ‑9, and significantly reduced the protein levels of galectin‑3 in LoVo cells compared with control shRNA (P<0.05). These data indicate that knockdown of LI‑cadherin facilitates the invasion of cancer cells by degrading extracellular matrix components via activation of MMP‑2 and ‑9, and increases cancer cell adhesion and migration via altered expression of galectin‑3. This suggests that LI‑cadherin serves an important role in the invasion and metastasis of colorectal cancer, and may be used as a potential therapeutic target.
