Orchestrating the metastatic symphony: the role of extracellular vesicles in the epithelial–mesenchymal transition and pulmonary niche formation of breast cancer

Biological Reviews, EarlyView.
ABSTRACT The complexity of breast cancer (BC) lung metastasis lies in the capacity of tumour cells to interact efficiently with distant organs to promote colonisation, a process that involves the sophisticated coordination of inherent cellular plasticity and the remodelling of the distant microenvironment.

Ion Activation Methods for Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

Epigenetic Regulation of Liver Fibrosis: Mechanisms and Therapeutic Implications

Portal Hypertension &Cirrhosis, EarlyView.
This review synthesizes the epigenetic mechanisms—DNA methylation, histone modifications, and non‐coding RNAs—that drive hepatic stellate cell activation and the progression of liver fibrosis. It further evaluates emerging therapeutic strategies targeting these epigenetic regulators, including DNA methyltransferase and histone deacetylase inhibitors ...

RNF13 regulates the endolysosomal pathway through interaction with the small GTPase Arl8B

The FEBS Journal, EarlyView.
The E3 ubiquitin ligase RNF13 functions as a regulatory scaffold, organizing Arl8B‐dependent complexes and tuning downstream signaling that controls endolysosomal organization and trafficking. In this model, wild‐type RNF13 associates with Arl8B on endolysosomes, whereas Arl8B (E22D/F55A) or RNF13 (L244A) variants weaken complex assembly, potentially ...

Stimulating proteasomal degradation in human proteinopathies

The FEBS Journal, EarlyView.
The proteasome mediates the degradation of a wide range of proteins. Boosting proteasomal degradation may be beneficial in several disease contexts and can be achieved either by modulating proteasome activity or by improving substrate delivery. Proteasome activity can be enhanced by increasing proteasome abundance, inducing constitutive gate opening ...

The nucleosome-remodeling ATPase ISWI is regulated by poly-ADP-ribosylation.

PLoS Biology, 2008
ATP-dependent nucleosome-remodeling enzymes and covalent modifiers of chromatin set the functional state of chromatin. However, how these enzymatic activities are coordinated in the nucleus is largely unknown.

Tankyrase‐2 regulates adipocyte differentiation through AMPK/mTOR signaling

The FEBS Journal, EarlyView.
Tankyrase 2 (TNKS2), a PARP family member, underpins adipocyte differentiation. TNKS2 controls LKB1 protein level, and consequently, the activity of the mTOR/AMPK system and adipocyte differentiation through a layered process. Pharmacological inhibition of TNKS2 leaves other PARPs and DNA repair active and therefore represents a novel target in ...

Structures of the UBR4 complex reveal a giant arena to capture diverse substrates for ubiquitin chain elongation

The FEBS Journal, EarlyView.
This review summarizes recent structures of the UBR4 complex, a giant E4 ubiquitin ligase which recognizes proteins with pre‐existing ubiquitin modifications and marks them for degradation. The UBR4 complex uses a large arena lined with substrate interaction modules to select features on ubiquitinated substrates, such as the presence of N‐degrons or ...
