The INAVA mRNA in Extracellular Vesicles Activates Normal Ovarian Fibroblasts by Phosphorylation–Ubiquitylation Crosstalk of HMGA2

Advanced Science, EarlyView.
Ovarian cancer‐derived extracellular vesicles (EVs) transfer INAVA mRNA to normal ovarian fibroblasts (NOFs). Translated INAVA protein inhibits HMGA2 phosphorylation‐dependent ubiquitylation and proteasomal degradation, promoting NOF activation.

The E3 Ubiquitin Ligase ARIH1 Facilitates Colorectal Cancer Progression by Promoting Oxidative Phosphorylation via the Mitochondrial Translocation of K63‐Linked Ubiquitinated PHB1

Advanced Science, EarlyView.
The RBR E3 ubiquitin ligase ARIH1, which is upregulated in colorectal cancer cells, promotes cell growth and metastasis and correlates with an unfavorable CRC prognosis. Mechanistically, ARIH1 catalyzes K63‐linked ubiquitination of PHB1, enhancing the interaction between PHB1 and Akt.

Two distinct modes for propagation of histone PTMs across the cell cycle [PDF]

, 2015
Epigenetic states defined by chromatin can be maintained through mitotic cell division. However, it remains unknown how histone-based information is transmitted.

Transient Interdomain Interactions Modulate the Monomeric Structural Ensemble and Self‐Assembly of Huntingtin Exon 1

Advanced Science, EarlyView.
Polyglutamine (polyQ) tract expansion (≥ 36 amino acids) within the N‐terminal region of the Huntingtin protein (Httex1) causes Huntington's disease (HD), for which the underlying causes are not well‐understood. The authors performed computer simulations to understand the cause of HD at the molecular level.

Post-translational modifications of lipid-activated nuclear receptors: Focus on metabolism [PDF]

, 2017
Post-translational modifications (PTM) occur to nearly all proteins, are catalysed by specific enzymes and are subjected to tight regulation. They have been shown to be a powerful means by which the function of proteins can be modified resulting in ...

HDAC6 and USP9X Control Glutamine Metabolism by Stabilizing GS to Promote Glioblastoma Tumorigenesis

Advanced Science, EarlyView.
Glioblastoma (GBM) growth relies on glutamine synthetase (GS), which is stabilized by histone deacetylase 6 (HDAC6) and deubiquitinated by ubiquitin‐specific peptidase 9, X‐linked (USP9X). HDAC6 promotes GS deacetylation, while USP9X removes its K48‐linked polyubiquitination, enhancing GS stability.

Macrophage WEE1 Directly Binds to and Phosphorylates NF‐κB p65 Subunit to Induce Inflammatory Response and Drive Atherosclerosis

Advanced Science, EarlyView.
The present study shows that macrophage WEE1 drives NF‐κB activation and inflammatory atherosclerosis by directly phosphorylating p65 at S536. This finding illustrates a macrophage‐specific WEE1‐p65 axis in regulating inflammatory atherosclerosis and points out new directions to broaden the clinical applications for WEE1 inhibitors in atherosclerosis ...
