A link between APOBEC3G and miRNA was previously suggested by Ding et al. (2012) [55], who observed that overexpression of APOBEC3G in colorectal liver metastasis, promoted cell migration and invasion due to the loss of miR-29-dependent repression of matrix metalloproteinase-2 (MMP-2). The gene discussed is APOBEC3G; the disease is medical procedure.
