By contrast, galectin‐3 facilitated cell motility in cancer cells by inducing MMPs, including MMP9 (Kim et al., 2011; Mauris, Woodward, Cao, Panjwani, & Argueso, 2014; Wang et al., 2012), and galectin‐3 gene silencing considerably suppressed the mRNA and protein levels of MMP9 (Zhang et al., 2012). The gene discussed is MMP9; the disease is cancer.
