eIF4G stimulates the activity of the DEAD box protein eIF4A by a conformational guidance mechanism [PDF]

, 2011
The activity of eIF4A, a key player in translation initiation, is regulated by other translation factors through currently unknown mechanisms. Here, we provide the necessary framework to understand the mechanism of eIF4A?s regulation by eIF4G.

Compartmentalisation in cAMP signalling: A phase separation perspective

British Journal of Pharmacology, EarlyView.
Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.

Identification of novel pathway partners of p68 and p72 RNA helicases through Oncomine meta-analysis [PDF]

, 2007
Background The Oncomine™ database is an online collection of microarrays from various sources, usually cancer-related, and contains many "multi-arrays" (collections of analyzed microarrays, in a single study).

Enhancing antitumour response to proteasome inhibitors with inhibitors of insulin‐degrading enzyme, a new molecular vulnerability in multiple myeloma

British Journal of Pharmacology, EarlyView.
Inhibitors of insulin‐degrading enzyme boost PI cytotoxicity through an increased sensitivity of proteasome to PI inhibitors, induction of ISR, DNA damage and Myc down‐regulation. They overcome PI resistance in vitro and induce tumour regression in vivo.

The RNA helicase DDX3X is an essential mediator of innate antimicrobial immunity.

PLoS Pathogens, 2018
DExD/H box RNA helicases, such as the RIG-I-like receptors (RLR), are important components of the innate immune system. Here we demonstrate a pivotal and sex-specific role for the heterosomal isoforms of the DEAD box RNA helicase DDX3 in the immune ...

Proteostasis of organelles in aging and disease

The FEBS Journal, EarlyView.
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

LINC00908 attenuates LUAD tumorigenesis through DEAD-box helicase 54

American Journal of Cancer Research
Lung adenocarcinoma (LUAD) is one of the leading causes of cancer-related death worldwide. We identified a specific long non-coding RNA (LncRNA), LINC00908, which was downregulated in LUAD tissues and associated with good outcome. LINC00908 inhibited glycolysis by regulating the expression of the DEAD-box helicase 54 (DDX54), which was screened by a ...

GCN2 in proteostasis: structural logic, signalling networks and disease

The FEBS Journal, EarlyView.
Threats to protein synthesis activate the kinase GCN2, initiating the integrated stress response (ISR). GCN2 is triggered by stalled ribosomes and uncharged tRNAs, which accumulate when amino acids are scarce. The ISR adjusts cellular physiology by promoting redox balance, protein quality control, and mitochondrial optimisation.

Translation termination depends on the sequential ribosomal entry of eRF1 and eRF3.

, 2019
Translation termination requires eRF1 and eRF3 for polypeptide-and tRNA-release on stop codons. Additionally, Dbp5/DDX19 and Rli1/ABCE1 are required; however, their function in this process is currently unknown.

Exercise‐related microRNAs in Caenorhabditis elegans regulate calcium homeostasis and mitochondrial dynamics: Conserved pathways, divergent microRNAs

The FEBS Journal, EarlyView.
Exercise‐related microRNAs cel‐miR‐249‐3p and cel‐miR‐77‐5p in C. elegans regulate lifespan, fitness, mitochondrial morphology and membrane potential. Although lacking direct mammalian orthologs, H2O2‐induced microRNAs mmu‐miR‐181a‐5p and mmu‐miR‐378a‐3p regulate myogenesis, autophagy, mitochondrial content and respiration in murine myoblasts ...
