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

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

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

Aging 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 ...

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

Molecular 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.

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

The 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.

Selinexor’s Immunomodulatory Impact in Advancing Multiple Myeloma Treatment

Cells
Despite the major advancements in the repertoire for multiple myeloma (MM) treatment, this disease remains a chronically progressive plasma cell malignancy. Drug resistance and high relapse rates complicate the extended treatment strategies. However, the

Modulation of anti-tumour immunity by XPO1 inhibitors [PDF]

Exploration of Targeted Anti-tumor Therapy
Exportin-1 (XPO1) is a nuclear export protein that, when overexpressed, can facilitate cancer cell proliferation and survival and is frequently overexpressed or mutated in cancer patients.

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

PLoS 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

American 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.

TFIIA transcriptional activity is controlled by a ‘cleave-and-run’ Exportin-1/Taspase 1-switch [PDF]

Journal of Molecular Cell Biology, 2017
Transcription factor TFIIA is controlled by complex regulatory networks including proteolysis by the protease Taspase 1, though the full impact of cleavage remains elusive. Here, we demonstrate that in contrast to the general assumption, de novo produced TFIIA is rapidly confined to the cytoplasm via an evolutionary conserved nuclear export signal (NES,
