Abstract:
Multiple members (DUSP1-29) of dual-specificity phosphatase (DSP) family are key regulators of mitogen-activated protein kinases (MAPKs), which regulate numerous physiological responses. Eight DUSPs are also named MAPK phosphatases (MKPs). DUSP dysregulation contributes to the pathogenesis of various human inflammatory and chronic diseases. Downregulation of DUSP1, DUSP3, DUSP11, and DUSP22, as well as upregulation of DUSP4, DUSP6, and DUSP23 are involved in human autoimmune diseases. Besides autoimmune diseases, reduction of DUSP1, DUSP2, and DUSP14, as well as induction of DUSP8 contribute to the pathogenesis of allergic diseases. Additionally, decreased levels of DUSP2, DUSP11, DUSP22, and DUSP28 are associated with human inflammatory bowel diseases. Moreover, deficiency of 10 DUSPs, as well as induction of DUSP4 are associated with metabolic diseases. Downregulation of 5 DUSPs are involved in cardiovascular disease pathogenesis; in contrast, upregulation of other 5 DUSPs are correlated with cardiovascular diseases. Collectively, dysregulated DUSPs could be diagnostic biomarkers and therapeutic targets for inflammatory diseases. Due to complex expression patterns of DUSPs, it is crucial to study the regulatory mechanisms of individual DUSPs in various inflammatory and chronic diseases. In this review, we summarize the roles and regulatory mechanisms of DUSPs in human inflammatory and chronic diseases. We also discuss the potential therapeutic applications of DUSP agonists/inhibitors in human inflammatory and chronic diseases.
Insights
Dual-specificity phosphatases (DUSPs) regulate mitogen-activated protein kinases (MAPKs). Dysregulated DUSPs are implicated in inflammatory diseases, offering potential diagnostic and therapeutic targets.
Area of Science:
- Biochemistry and Molecular Biology
- Immunology
- Pathology
Background:
- Dual-specificity phosphatases (DUSPs) are critical regulators of mitogen-activated protein kinases (MAPKs).
- Dysregulation of DUSPs is linked to the pathogenesis of numerous human inflammatory and chronic diseases, including autoimmune, allergic, inflammatory bowel, metabolic, and cardiovascular diseases.
- Specific DUSP members show altered expression patterns (downregulation or upregulation) across different disease states.
Purpose of the Study:
- To review the roles and regulatory mechanisms of DUSPs in human inflammatory and chronic diseases.
- To explore the potential therapeutic applications of DUSP modulators (agonists/inhibitors).
Main Methods:
- Literature review summarizing existing research on DUSP involvement in various diseases.
- Analysis of DUSP expression patterns and their association with disease pathogenesis.
- Discussion of DUSP regulatory mechanisms and therapeutic potential.
Main Results:
- DUSP dysregulation is a common feature across diverse inflammatory and chronic diseases.
- Specific DUSPs are implicated in autoimmune diseases (e.g., DUSP1, DUSP4), allergic diseases (e.g., DUSP1, DUSP8), inflammatory bowel diseases (e.g., DUSP2, DUSP11), metabolic diseases, and cardiovascular diseases.
- Altered DUSP expression can serve as diagnostic biomarkers and therapeutic targets.
Conclusions:
- Dysregulated DUSPs are key players in the pathogenesis of inflammatory and chronic diseases.
- Understanding individual DUSP regulatory mechanisms is crucial for developing targeted therapies.
- DUSP agonists and inhibitors represent promising therapeutic strategies for managing these conditions.
