Overexpression of miR-146b-5p could inhibit the growth of glomerular mesangial cells and reduce the levels of IL6 and IL8 in lupus nephritis [27]; suppress cell proliferation, migration, and invasion in non-small cell lung cancer [28]; promote cell growth, invasion, and glycolysis in colorectal cancer [29]; and slow down the growth of Ishikawa cells in the present study. This evidence concerns the gene CXCL8 and colorectal cancer.
