The Roles of CCCH-Zinc Finger Proteins in the Regulation of Inflammation.
Nearly 60 CCCH-zinc finger proteins have been identified in humans and mice. These proteins are involved in the regulation of multiple steps of RNA metabolism, including mRNA splicing, polyadenylation, transportation, translation, and decay. Several CCCH-zinc finger proteins, such as tristetraprolin, Roquin and MCPIP1, are crucial for many aspects of immune responses via targeting mRNA degradation and other mechanisms. Others are involved in the regulation of cell differentiation and cancer cell growth. In the past ten years, we have been working on a novel CCCH-zinc finger containing protein, MCPIP1, in the regulation of both innate and adaptive immunity. Using transgenic and knockout mouse models, we are studying the physiological role and mechanisms of MCPIP1 in inflammatory response and immunity and the involvement of MCPIP1 in septic shock, atherosclerosis and autoimmune diseases.
Novel Molecular Regulators in Vascular Endothelial Inflammation, Injury and Repair.
Vascular endothelium is a multifunctional and critical interface between blood stream and vascular wall. Meanwhile, vascular endothelium is also the largest endocrine, paracrine and metabolic organ. Recent studies suggest that there is endothelial dysfunction at the early stage of cardiovascular diseases and stroke caused by atherosclerosis, hypertension and diabetes. In addition, the initial event in bacterial and viral infection-caused multi-organ injury is vascular endothelial damage and dysfunction. So that vascular endothelial inflammation and dysfunction is a common pathological step and basis for cardiovascular diseases and stroke and acute organ injury. Improving the function of vascular endothelium and repairing the damaged vascular endothelium would be a critical step for treatment of cardiovascular diseases and stroke and acute organ injury. Using expression profiling and bioinformatics, we recently identified an adipocyte-enriched protein, adiporedoxin, as a negative regulator of endothelial activation (Sci Rep, 2016). In addition, we have identified a TRIM protein as a novel determinant of vascular endothelial inflammation via targeting VCAM-1 degradation. Currently, we are studying the roles and mechanisms of these proteins in vascular inflammation, atherosclerosis, sepsis and cerebral small vascular disease.
