Key Takeaway
Note that OTUD1 may serve as a biomarker for tumor prognosis and a target for cardiovascular pathology.

This systematic review explores the physiological and pathological roles of OTUD1-mediated deubiquitination across various conditions, including tumors, cardiovascular diseases, and metabolic diseases. The synthesis indicates that OTUD1 acts as a negative regulator of NF-kappaB inflammatory signaling and type I interferon responses while maintaining immune and oxidative homeostasis.

In oncology, the role of OTUD1 is tissue-dependent; it is downregulated in most epithelial tumors to suppress malignant progression but upregulated in certain tumors where it promotes pathological remodeling. In cardiovascular and metabolic contexts, OTUD1 is upregulated and drives hypertrophy and fibrosis. The review notes that OTUD1 correlates with tumor stage, prognosis, and therapeutic sensitivity, suggesting its potential as a biomarker for diagnostic subtyping.

Several limitations are noted, including marked tissue functional heterogeneity and the discovery of non-enzymatic scaffold functions. Furthermore, clinical translation is currently hindered by a lack of highly selective targeting probes. These findings suggest OTUD1 may serve as a target for precision diagnostic and therapeutic strategies, though its role remains context-dependent.

How this fits prior evidence

This finding addresses a gap in the understanding of molecular drivers within the cardiometabolic continuum. While previous evidence established a unified cardiometabolic disease framework linking T2DM, ASCVD, HFpEF, MASLD, hypertension, and CKD via shared pathophysiology, this review identifies OTUD1 as a specific driver of hypertrophy and fibrosis in the cardiovascular system.

The body uses proteins to keep our systems in balance. One specific protein, OTUD1, plays a critical role by keeping inflammation and immune responses from becoming too active. However, when this protein behaves differently depending on where it is in the body, it can lead to serious health problems. In some cases, its activity helps maintain balance, but in others, it can drive harmful changes like tissue scarring or tumor growth.

Research shows that OTUD1 levels are linked to how far a tumor has progressed and how well it might respond to treatment. This makes it a promising candidate for a biomarker, which is a measurable sign used by doctors to diagnose diseases and predict patient outcomes. Because its role changes based on the specific tissue type, it could help doctors better categorize different types of cancer.

While these findings are promising for precision medicine, there are hurdles to clear. The protein's behavior varies greatly between tissues, and scientists currently lack highly specific tools to target it directly. These results come from a review of existing research, meaning more study is needed to understand exactly how it functions in different clinical settings.

What this means for you:
OTUD1 could help doctors better diagnose cancer stages and predict treatment success based on its role in inflammation.

Common questions

What role does OTUD1 play in the body?

OTUD1 helps keep your body's systems in balance. It works by limiting excessive inflammation and controlling immune responses. However, its role changes depending on where it is located; while it helps maintain health in some areas, it can promote harmful changes like tissue scarring or tumor growth in others.

How can OTUD1 help with cancer treatment?

OTUD1 levels are linked to how far a tumor has progressed and how well it might respond to therapy. This means it could be used as a biomarker, which is a tool for doctors to better diagnose specific types of tumors and predict a patient's outlook.

Is OTUD1 currently being used as a medicine?

Not yet. While it shows potential as a target for new therapies and a way to track disease, scientists currently lack the specific tools needed to target it directly in patients. Its effects are also very different depending on the type of tissue involved.

OTUD1 is a deubiquitinase of the OTU family that participates in immune signaling, redox balance, and cell death through modulating substrate ubiquitination. Under physiological conditions, OTUD1 primarily exerts negative regulatory effects, restricting excessive activation of NF-κB inflammatory signaling and type I interferon responses, thereby maintaining immune and oxidative homeostasis. Under pathological conditions, its functional effects undergo tissue-dependent reprogramming: it is downregulated in most epithelial tumors and suppresses malignant progression, whereas it is upregulated in certain tumors and cardiovascular or metabolic diseases and promotes pathological remodeling. It exerts protective regulation in the nervous system and mucosal inflammation, yet drives hypertrophy and fibrosis in the cardiovascular system. Preclinical studies indicate that OTUD1 expression levels correlate with tumor stage, prognosis, and therapeutic sensitivity, suggesting potential as a biomarker for diagnostic subtyping and prognostic assessment. However, marked tissue functional heterogeneity, the discovery of non-enzymatic scaffold functions, and the lack of highly selective targeting probes constitute central bottlenecks for clinical translation. This review systematically summarizes the molecular characteristics, physiological functions, disease regulatory networks, and current clinical translational status of OTUD1, with the aim of clarifying the molecular basis of its functional duality and providing a theoretical foundation for optimizing precision diagnostic and therapeutic strategies targeting OTUD1.
