SPHINX31 acts as a SRPK1 inhibitor targeting the ATR/DNA‐PKcs/CHK1 replicative checkpoint to inhibit cell growth in non‐small cell lung cancer

Molecular Oncology, EarlyView.
The kinase SRPK1 directly interacts with the protein TOPBP1 and regulates the pre‐mRNA splicing of WIZ thereby contributing to the activation of the ATR/CHK1 replicative checkpoint in response to replicative stress. This allows cancer cells' genomic stability and survival.

Uncovering a cryptic allosteric hub governing energy landscape plasticity within the Nur77 ligand-binding domain

Magnetic Resonance Letters
Nur77 (NR4A1) is an orphan nuclear receptor whose allosteric mechanism departs fundamentally from that of classical nuclear receptors. Its ligand-binding pocket is constitutively occupied by endogenous hydrophobic side chains, obscuring the structural ...

Temperature and magnetic field dependence of a Kondo system in the weak coupling regime [PDF]

, 2013
The Kondo effect arises due to the interaction between a localized spin and the electrons of a surrounding host. Studies of individual magnetic impurities by scanning tunneling spectroscopy have renewed interest in Kondo physics; however, a quantitative ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Structural insights into a highly flexible zinc finger module unravel INSM1 function in transcription regulation

Nature Communications
Orderly development of neuroendocrine and nervous system of mammals requires INSM1, a key regulator for cell differentiation. Ectopic expression of INSM1 is closely correlated with human neuroendocrine tumorigenesis, which makes INSM1 a reliable ...

Dose‐dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

FEBS Open Bio, EarlyView.
NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

Design of an engineered Gα

Magnetic Resonance Letters
G protein-coupled receptors (GPCRs) are pivotal therapeutic targets that signal through heterotrimeric G proteins. While structural insights into Gα s and Gα i/o subfamilies have advanced significantly, characterizing the Gα q/11 subfamily remains ...

Adenosine triphosphate as a modulator of protein interactions and stability

FEBS Open Bio, EarlyView.
ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...
