Lennox–Gastaut syndrome unveiled: Advancing diagnosis, therapies, and advocacy‐insights from the Genoa International Workshop

Epilepsia, EarlyView.
Abstract Lennox–Gastaut syndrome (LGS) is one of the most severe, yet one of the most discussed, childhood‐onset developmental and epileptic encephalopathies (DEEs). Dissent among epileptologists on the definition and minimum set of electroclinical features derives from the high etiological heterogeneity within the syndrome, which could make its ...

Human FASTK preferentially binds single‐stranded and G‐rich RNA

The FEBS Journal, EarlyView.
Although FASTK is known to play a role in mRNA biology, the mechanism through which it recognizes RNA has yet to be unraveled. Here, we used purified human FASTK to characterize its RNA‐binding properties in vitro. We found that FASTK prefers ssRNA oligonucleotides containing guanines with the potential to form G‐quadruplexes and binds robustly to any ...

Molecular basis of antibiotic sensing by the TetR family regulator CecR – a structural perspective

The FEBS Journal, EarlyView.
Escherichia coli CecR, a member of the TetR family regulators, senses selected antibiotics and activates the expression of a putative drug efflux pump. Although present in many pathogenic Enterobacteriales strains, CecR remains poorly characterized. We present the first CecR crystal structure, which reveals a unique tunnel‐like ligand‐binding cavity ...

SARS‐CoV‐2 nucleocapsid protein variants have differential RNA chaperone activity

The FEBS Journal, EarlyView.
The SARS‐CoV‐2 nucleocapsid (N) protein facilitates RNA annealing through its RBD–IDR2–CTD region, identifying it as a functional RNA chaperone. The Omicron BA.5 variant shows reduced chaperone activity compared to the Wuhan wild‐type protein. Although phosphorylation has no effect on wild‐type N, phosphomimetic modification of BA.5 N restores its RNA ...

8-Oxoguanine Disrupts G-Quadruplex DNA Stability and Modulates FANCJ AKKQ Peptide Binding

Molecules
Guanine-rich nucleic acid sequences can adopt G-quadruplex (G4) structures, which pose barriers to DNA replication and repair. The FANCJ helicase contributes to genome stability by resolving these structures, a function linked to its G4-binding site that

Oxygen‐independent expression of HIF‐1α during the cell cycle in hepatocellular carcinoma cells controls essential metabolic pathways under normoxia

The FEBS Journal, EarlyView.
In Huh7 cells, HIF‐1α is essential as it maintains the expression of proteins involved in glycolysis and steroid/cholesterol biosynthesis both under normoxia and hypoxia. On the other hand, in HeLa cells, these pathways are induced by HIF‐1α only under hypoxia.
