SUMO--a post-translational modification with therapeutic potential?

Current Opinion in Pharmacology
Chang-Hoon Woo, Jun-ichi Abe


Sumoylation is a covalent modification, which is mediated by small ubiquitin-like modifier (SUMO) polypeptides. A growing body of evidence has shown that sumoylation affects the functional properties of many substrates in the regulation of cellular processes. Recent reports indicate the crucial role of sumoylation in human diseases including familial dilated cardiomyopathy, suggesting that targeting of sumoylation would be of considerable interest for novel therapies. Even though hundreds of SUMO substrates have been identified, their pathophysiological roles remain to be determined. Among them, ERK5-sumoylation has recently been linked to diabetes and implicated in endothelial dysfunction and cardiomyocyte apoptosis in vivo. These findings support the idea that ERK5-sumoylation is a novel therapeutic target for the treatment of diabetes-related cardiovascular diseases.

Anti-inflammatory Treatments

A drug or substance that reduces inflammation (redness, swelling, and pain) in the body. Anti-inflammatory agents block certain substances in the body that cause inflammation and swelling. Discover the latest research on anti-inflammatory treatments here


Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.

Cardiovascular Inflammation

Inflammation plays a significant role in the development of cardiovascular diseases, an understanding of these endogenous processes is critical for evaluating the risks and potential treatment strategies. Discover the latest research on cardiovascular inflammation here.


Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
