Okanin Suppresses the Growth of Colorectal Cancer Cells by Targeting at Peroxiredoxin 5

Advanced Science, EarlyView.
Okanin suppresses colorectal cancer growth by directly targeting PRDX5. This natural compound selectively binds peroxiredoxin 5 (PRDX5), inhibiting its activity and inducing WSB1‐mediated degradation. PRDX5 loss elevates ROS, suppresses GPX4 via SIAH2, and further triggers cell death (apoptosis and ferroptosis).

Targeting Intratumoral Copper Inhibits Tumor Progression via p62‐Mediated EZH2 Degradation and Potentiates Anti‐PD‐1 Immunotherapy in Oral Squamous Cell Carcinoma

Advanced Science, EarlyView.
The authors find that by targeting intratumoral copper, they can enhance p62‐mediated ubiquitination of EZH2 at the Ub‐K63 site by suppressing copper binding to SMURF2, an E3 ligase of EZH2, leading to its autophagic degradation. This mechanism suppressed OSCC progression and potentiated anti‐PD‐1 immunotherapy, highlighting a potential new therapeutic

RNF8/UBC13 ubiquitin signaling suppresses synapse formation in the mammalian brain

Nature Communications, 2017
Ubiquitin ligases play critical roles in neuronal connectivity in the brain. Here, Valnegri and colleagues show that ubiquitin ligase RNF8 and ubiquitin-conjugating enzyme UBC13 regulate synapse number in cerebellar granule neurons and rodent cerebellar ...

A Tyrosine Switch on NEDD4-2 E3 Ligase Transmits GPCR Inflammatory Signaling

Cell Reports, 2018
Summary: Ubiquitination is essential for protein degradation and signaling and pivotal to many physiological processes. Ubiquitination of a subset of G-protein-coupled receptors (GPCRs) by the E3 ligase NEDD4-2 is required for p38 activation, but how ...

Integrative Omics Reveals Glutamine Catabolism‐Driven Apoptotic Suppression in Monocytes upon Mechanical Unloading

Advanced Science, EarlyView.
This research integrated multi‐omics analysis of bone tissue from HLU and control mice revealed that mechanical unloading suppresses intrinsic apoptosis and augments glutamine (Gln) catabolism in osteoclast lineage cells. The findings highlight pivotal roles for SLC1A5‐mediated Gln metabolism and XIAP/Diablo axis‐mediated apoptosis suppression.

Origin and Diversification of TRIM Ubiquitin Ligases

PLoS ONE, 2012
Most proteins of the TRIM family (also known as RBCC family) are ubiquitin ligases that share a peculiar protein structure, characterized by including an N-terminal RING finger domain closely followed by one or two B-boxes. Additional protein domains found at their C termini have been used to classify TRIM proteins into classes.

Antagonistic roles of ubiquitin ligase HEI10 and SUMO ligase RNF212 regulate meiotic recombination

Nature Genetics, 2014
Crossover recombination facilitates the accurate segregation of homologous chromosomes during meiosis. In mammals, poorly characterized regulatory processes ensure that every pair of chromosomes obtains at least one crossover, even though most ...

CircPVT1 Promotes Lung Metastasis and Tumor Progression in Renal Cell Carcinoma by Encoding the cP104aa Peptide and Targeting EIF4A3

Advanced Science, EarlyView.
This study reveals that circPVT1 promotes the renal cell carcinoma lung metastasis and tumor progression through encoding the cP104aa peptide and directly binds with EIF4A3, which jointly regulates the target gene c‐MYC. Abstract Circular RNA (circRNA) plays a pivotal role in the pathogenesis of renal cell carcinoma (RCC).

Ubiquitination‐Dependent LLGL2 Degradation Drives Colorectal Cancer Progression via THBS3 mRNA Stabilization

Advanced Science, EarlyView.
During the progression of CRC, MDM2, as an E3 ubiquitin ligase, promotes the degradation of the LLGL2 protein. Reduced expression of the LLGL2 protein leads to the loss of support for the CNOT1 protein, decreasing the degradation of THBS3 mRNA. The increased THBS3 further activates the PI3K‐Akt pathway, promoting the proliferation and metastasis of CRC.

The role of ubiquitin ligases in cardiac disease

Journal of Molecular and Cellular Cardiology, 2014
Rigorous surveillance of protein quality control is essential for the maintenance of normal cardiac function, while the dysregulation of protein turnover is present in a diverse array of common cardiac diseases. Central to the protein quality control found in all cells is the ubiquitin proteasome system (UPS).
