Post-translational attachment of small ubiquitin-like modifier (SUMO), defined as SUMOylation, has emerged as a new mechanism of protein regulation in plant biology. In plant, SUMOylation has been shown to play crucial roles in a variety of biotic and abiotic stress responses. Recent work using viable mutants with defective SUMOylation have indicated an important role for SUMOylation in a wide range of developmental processes, such as cell division, expansion, survival and differentiation, vegetative growth and reproductive development. This review will summarize the currently emerging information regarding the function of SUMOylation in plant development.

Small ubiquitin-like modifier (SUMO) plays a pivotal role in diverse cellular processes and is implicated in diseases such as cancer and neurodegenerative disorders. However, large-scale identification of endogenous SUMO-1 faces challenges due to limited enrichment methods and its lower abundance compared to SUMO-2/3. Here we propose a novel combinatorial peptide strategy, combined with anti-adhesive polymer development, to enrich endogenous SUMO-1 modified peptides, revealing a comprehensive SUMOylation landscape.

Reduction of glucose transporter 1 (GLUT1), even deletion, may results in cartilage fibrosis and osteoarthritis. This study aims to investigate the SUMOylation of GLUT1 in osteoarthritis through small ubiquitin-like modifier 1(SUMO1), and explore the role of SUMOylated GLUT1 in glycometabolism, proliferation and apoptosis in chondrocytes. Human chondrocytes were incubated with 10 ng/mL of IL-1β to mimic osteoarthritis in vitro.

Alzheimer's disease (AD), the most prevalent form of dementia in the elderly, involves critical changes such as reduced aerobic glycolysis in astrocytes and increased neuronal apoptosis, both of which are significant in the disease's pathology. In our study, astrocytes treated with amyloid β1-42 (Aβ) to simulate AD conditions exhibited upregulated expressions of small ubiquitin-like modifier (SUMO)-specific protease 1 (SENP1) and Pumilio RNA Binding Family Member 2 (PUM2), alongside decreased levels of Nuclear factor erythroid 2-related factor 2 (NRF2). SENP1 is notably the most upregulated SUMOylation enzyme in Aβ-exposed astrocytes.

SUMOylation is a protein modification process that involves the covalent attachment of a small ubiquitin-like modifier (SUMO) to a specific lysine residue on the target protein. This modification can influence the function, localization, stability, and interactions of proteins, thereby regulating various cellular processes. Altering the SUMOylation of certain proteins is expected to be a potential approach for treating specific cancers and diseases.
