CUEDC2, a CUE-domain-containing protein, modulates inflammation, but its involvement in tumorigenesis is still poorly understood. Here, we report that CUEDC2 is a key regulator of macrophage function and critical for protection against colitis-associated tumorigenesis. CUEDC2 expression is dramatically upregulated during macrophage differentiation, and CUEDC2 deficiency results in excessive production of proinflammatory cytokines. The level of CUEDC2 in macrophages is modulated by miR- 324-5p. We find that Cuedc2 KO mice are more susceptible to dextran-sodium-sulfate-induced colitis, and macrophage transplantation results suggest that the increased susceptibility results from the dysfunction of macrophages lacking CUEDC2. Furthermore, we find that Cuedc2 KO mice are more prone to colitis-associated cancer. Importantly, CUEDC2 expression is almost undetectable in macrophages in human colon cancer, and this decreased CUEDC2 expression is associated with high levels of interleukin-4 and miR-324-5p. Thus, CUEDC2 plays a crucial role in modulating macrophage function and is associated with both colitis and colon tumorigenesis.

Shunt derived from MMIMS inert gas retention data correlated well with R-S during breathing of oxygen. Shunt as derived by MMIMS was generally less than R-S.

A dual-responsive nanoparticle system was designed for the efficient delivery of genes and chemotherapeutic agents through polymer degradation responding orderly to the tumor intracellular pH and redox state.

Findings highlight the need for nurses to explore patients' use of fatigue self-management behaviours and the effectiveness of these behaviours in reducing fatigue. Interventions that improve patients' self-efficacy and neighbourhood supports have the potential to improve outcomes from fatigue self-management behaviours.
