Cold water immersion in recovery following a single bout resistance exercise suppresses mechanisms of miRNA nuclear export and maturation

open access: yesPhysiological Reports, 2023
Cold water immersion (CWI) following intense exercise is a common athletic recovery practice. However, CWI impacts muscle adaptations to exercise training, with attenuated muscle hypertrophy and increased angiogenesis.

Goniothalamin as a Styryl‐Lactone Toxicophore in Cancer Models: Electrophile‐Driven DNA Damage, Reactive Oxygen Species–Endoplasmic Reticulum Stress Signaling and Detoxification‐Relevant Safety Considerations

open access: yesJournal of Biochemical and Molecular Toxicology, Volume 40, Issue 8, August 2026.
Goniothalamin (GTN) exerts anticancer effects by promoting reactive oxygen species (ROS) generation, glutathione (GSH) depletion, DNA damage, endoplasmic reticulum (ER) stress, and mitochondrial dysfunction. These interconnected events trigger apoptosis, necroptosis, anoikis, and autophagy, while modulating mitogen‐activated protein kinase (MAPK ...

Progerin Hinders Autophagy Flux at Its Final Stages in Hutchinson‐Gilford Progeria Syndrome Cells, Preventing Its Own Autophagic Degradation

open access: yesAging Cell, Volume 25, Issue 8, August 2026.
We demonstrated that progerin induces the formation of autophagosomes but impairs their maturation and subsequent fusion with lysosomes. Progerin impedes proper autophagy flux, thus preventing its own autophagic degradation. Selinexor treatment improved both autophagosome maturation and autophagosome‐lysosome fusion, which ultimately led to effective ...

Resistance‐exercise‐induced stress intervenes in TGF‐β signaling by cooperatively downregulating nuclear αB‐crystallin and SMAD4 in human skeletal muscle fibers

open access: yesThe FEBS Journal, Volume 293, Issue 15, Page 4624-4644, August 2026.
Alpha‐crystallin B chain (CRYAB) has been reported to stabilize mothers against decapentaplegic homolog 4 (SMAD4) in transforming growth factor‐β (TGF‐β) signaling, enabling target gene transcription. We show nuclear CRYAB–SMAD4 interaction for the first time in human skeletal muscle fibers and its regulation by exercise.

Decrease of 5-hydroxymethylcytosine and TET1 with nuclear exclusion of TET2 in small intestinal neuroendocrine tumors

open access: yesBMC Cancer, 2018
Background Small intestinal neuroendocrine tumors (SI-NETs) originate from enterochromaffin cells scattered in the intestinal mucosa of the ileum and jejunum.

Evolutionary constraints acting on DDX3X protein potentially interferes with Rev-mediated nuclear export of HIV-1 RNA. [PDF]

open access: yesPLoS ONE, 2010
Differential host-pathogen interactions direct viral replication in infected cells. In HIV-1 infected cells, nuclear export of viral RNA transcripts into cellular cytoplasm is governed by interaction of HIV-1 Rev, Exportin-1 (CRM-1) and DDX3X. Knock down

Navigating the Post‐BCMA/GPRC5D Landscape: Efficacy of Selinexor, Bortezomib, and Dexamethasone After Sequential Immunotherapy Failure in Penta‐Refractory Multiple Myeloma—A Multicenter Analysis

open access: yesAmerican Journal of Hematology, Volume 101, Issue 7, Page 1433-1439, July 2026.
ABSTRACT Patients with relapsed/refractory multiple myeloma (RRMM) who are penta‐drug refractory, defined as resistant to two proteasome inhibitors, two immunomodulatory agents, and an anti‐CD38 monoclonal antibody, face a dismal prognosis, particularly after exposure to T‐cell–redirecting therapies.

Importin 7 and Exportin 1 Link c-Myc and p53 to Regulation of Ribosomal Biogenesis [PDF]

open access: yesMolecular Cell, 2012
Members of the β-karyopherin family mediate nuclear import of ribosomal proteins and export of ribosomal subunits, both required for ribosome biogenesis. We report that transcription of the β-karyopherin genes importin 7 (IPO7) and exportin 1 (XPO1), and several additional nuclear import receptors, is regulated positively by c-Myc and negatively by p53.

The Arabidopsis thaliana F-box gene HAWAIIAN SKIRT is a new player in the microRNA pathway. [PDF]

open access: yesPLoS ONE, 2017
In Arabidopsis, the F-box HAWAIIAN SKIRT (HWS) protein is important for organ growth. Loss of function of HWS exhibits pleiotropic phenotypes including sepal fusion.
