Going viral − Virus‐targeting nanobodies for research, diagnostics and therapy

FEBS Letters, EarlyView.
The increasing prevalence of viral diseases represents a major threat for global human health. Nanobodies, small binding fragments derived from camelid heavy‐chain antibodies, offer versatile tools for viral research, diagnostics, and antiviral therapy.

Semaphorin-3A Promotes Degradation of Fragile X Mental Retardation Protein in Growth Cones via the Ubiquitin-Proteasome Pathway

Frontiers in Neural Circuits, 2020
Fragile X mental retardation protein (FMRP) is an RNA-binding protein that regulates local translation in dendrites and spines for synaptic plasticity. In axons, FMRP is implicated in axonal extension and axon guidance.

How structural disorder and polyelectrolyte properties of prothymosin α enable its large interactome

FEBS Letters, EarlyView.
In this review, complexes of the fully disordered and highly negatively charged prothymosin α are collected, described, and discussed. Linked to its poly‐electrostatic character, prothymosin α engages a large interactome through multiple different binding modes ranging from fully disordered complexes to short linear motif (SLiM)‐driven interactions ...

Pharmacokinetic aspects of the clinically used proteasome inhibitor drugs and efforts toward nanoparticulate delivery systems

, 2021
Background Proteasome inhibitor drugs have provided a major breakthrough in the treatment of multiple myeloma and other hematological malignancies. Currently, there are three clinically used proteasome inhibitor drugs, namely bortezomib, carfilzomib, and

Mitochondrial translation and coordinated cytosolic translation in metabolic homeostasis and disease

FEBS Letters, EarlyView.
Mitochondrial function depends on coordinated protein production from the nuclear and mitochondrial genomes. This review highlights how cytosolic and mitochondrial translation, mRNA localization, protein import, and respiratory complex assembly are integrated to maintain mitochondrial proteostasis and function.

A role for eIF5A in translational control of stress‐inducible proteins in multiple myeloma cell lines

Molecular Oncology, EarlyView.
Loss of eIF5A rewires thapsigargin‐mediated endoplasmic reticulum stress responses in multiple myeloma cells by selective translation of mRNA transcripts, consequently dampening thapsigargin‐induced unfolded protein response (UPR) activation and shifting the balance from induction of apoptosis toward cell survival and proliferation.

Targeting the EpCAM‐AXL axis to overcome drug resistance in lung cancer

Molecular Oncology, EarlyView.
Lung cancer cells often evade therapy by hijacking signaling pathways. We reveal that cleaved EpCAM (sEpCAM) stabilizes the oncogenic protein AXL, driving NF‐κB and STAT3‐mediated chemoresistance. This EpCAM‐AXL axis identifies a high‐risk patient subset with poor prognosis.

Tissue- and developmental stage-specific changes in the subcellular localization of the 26S proteasome in the ovary of Drosophila melanogaster [PDF]

, 2004
The intracellular localization of the 26S proteasome in the different ovarian cell types of Drosophila melanogaster was studied by means of immunofluorescence staining and laser scanning microscopy, with the use of antibodies specific for regulatory ...

Molecular mechanisms for synergistic effect of proteasome inhibitors with platinum-based therapy in solid tumors

Taiwanese Journal of Obstetrics & Gynecology, 2016
The successful development of the proteasome inhibitor bortezomib as an anticancer drug has improved survival in patients with multiple myeloma. With the emergence of the newly US Food and Drug Administration-approved proteasome inhibitor carfilzomib ...

The multifaceted roles of lysosomes in cancer

Molecular Oncology, EarlyView.
Lysosomes support cancer cell adaptation by integrating macromolecule degradation and nutrient recycling with nutrient sensing, inter‐organelle communication and immune regulation. These interconnected functions can promote tumour growth, stress tolerance and therapy resistance, while also creating context‐dependent vulnerabilities that may be ...
