Reference title
A microRNA 221- and 222-mediated feedback loop maintains constitutive activation of NFkB and STAT3 in colorectal cancer cells.
Experimental verification
Western blot;qRT-PCR;luciferase reporter assays
Functional description
Colorectal cancer cell lines were transfected with MIR221 or MIR222 sponges. The activity levels of NFKB and STAT3 were measured in dual luciferase reporter assays. Immunoblot and real-time PCR analyses to measure protein and mRNA levels. Cells were analyzed by proliferation, viability, and flow cytometry analyses. In agreement with the causal roles of NFKB and STAT3 in CAC development, our data vevealed dramatically decreased levels of RELA and STAT3 protein expression in tumors from mice treated with the MIR221/222 sponge. Intriguingly, treatment with the MIR221/222 sponge significantly inhibited colitis, as indicated by body weight loss, colon shortening and inflammatory factor production.
