PG - 3240-3251 LID - 10.1038/onc.2016.468 [doi] AB - Chronic inflammation is believed to have a crucial role in colon cancer development. MicroRNA (miRNA) deregulation is common in human colorectal cancers, but little is known regarding whether miRNA drives tumor progression by regulating inflammation. Here, we showed that miR-19a can promote colitis and colitis-associated colon cancer (CAC) development using a CAC mouse model and an acute colitis mouse model. Tumor necrosis factor-alpha (TNF-alpha) stimulation can increase miR-19a expression, and upregulated miR-19a can in turn activate nuclear factor (NF)-kappaB signaling and TNF-alpha production by targeting TNF alpha-induced protein 3 (TNFAIP3). miR-19a inhibition can also alleviate CAC in vivo. Moreover, the regulatory effects of miR-19a on TNFAIP3 and NF-kappaB signaling were confirmed using tumor samples from patients with colon cancer. These new findings demonstrate that miR-19a has a direct role in upregulating NF-kappaB signaling and that miR-19a has roles in inflammation and CAC.
