ARTICLE HIGHLIGHTS
Research background

Colorectal cancer (CRC) is a common malignant tumor.

Research motivation

Alcohol consumption is positively correlated with CRC malignant metastasis; however, the mechanism is unclear.

Research objectives

To investigate the effects of alcohol on CRC metastasis

Research methods

The interaction between laminin-γ2 (LAMC2) and integrin-β1 (ITGB1) was measured by Duolink assay, and the expression levels of LAMC2, ITGB1 and focal adhesion kinase, snail, fibronectin, N-cadherin and special AT-rich sequence binding protein 1 were measured by quantitative real-time polymerase chain reaction, immunohistochemistry and western blotting. Interleukin-1β (IL-1β), tumor necrosis factor-α and IL-6 levels were measured via enzyme-linked immunosorbent assay, histopathological assessment via hematoxylin eosin staining, and determination of aberrant crypt foci via methylene blue.

Research results

Alcohol may promote CRC metastasis by influencing the molecular mechanism of the premetastatic niche.

Research conclusions

Our study suggests that alcohol promotes epithelial mesenchymal transformation-mediated premetastatic niche formation of CRC by activating the early interaction between LAMC2 and ITGB1 and lead to CRC metastasis.

Research perspectives

To explore the effect of alcohol on colorectal cancer metastasis.
