The past, present, and future of CRM1/XPO1 inhibitors

Stem Cell Investigation, 2019
Therapies targeted at inhibiting nucleo-cytoplasmic transport have found broad applications in the field of oncology. Chromosome region maintenance 1 (CRM1), better known as exportin 1 (XPO1), is the protein transporter responsible for the nucleo-cytoplasmic shuttling of most of the tumor suppressor proteins (TSP) and growth regulatory factors. XPO1 is

CRM1 mediates nuclear-cytoplasmic shuttling of mature microRNAs [PDF]

Proceedings of the National Academy of Sciences, 2009
Drosha-processed microRNAs (miRNAs) have been shown to be exported from the nucleus to the cytoplasm by Exportin 5, where they are processed a second time to generate mature miRNAs. In this work we show that miRNAs also use CRM1 for nuclear-cytoplasmic shuttling.

Phase-separated nuclear bodies of nucleoporin fusions promote condensation of MLL1/CRM1 and rearrangement of 3D genome structure

Cell Reports, 2023
Summary: NUP98 and NUP214 form chimeric fusion proteins that assemble into phase-separated nuclear bodies containing CRM1, a nuclear export receptor. However, these nuclear bodies’ function in controlling gene expression remains elusive.

Expression characteristics of dual‐specificity phosphatase 2 and hypoxia‐inducible factor‐1α in acute kidney injury and preliminary study of the effect of dual‐specificity phosphatase 2 on HK‐2 cells

Experimental Physiology, EarlyView.
ABSTRACT Acute kidney injury (AKI) is a global health problem with significant long‐term harm if the prognosis is poor. Dual‐specificity phosphatase 2 (DUSP2) is involved in key regulatory pathways in several disease processes, but its function in renal pathophysiology is unclear.

Dynamics of nuclear export of pre-ribosomal subunits revealed by high-speed single-molecule microscopy in live cells

iScience, 2023
Summary: We present a study on the nuclear export efficiency and time of pre-ribosomal subunits in live mammalian cells, using high-speed single-molecule tracking and single-molecule fluorescence resonance energy transfer techniques.

HNRNPD Induces Radioresistance in Nasopharyngeal Carcinoma by Sequestering GRAMD4 mRNA in Stress Granules

Advanced Science, Volume 13, Issue 43, 3 August 2026.
HNRNPD promotes radioresistance in nasopharyngeal carcinoma by enhancing stress granule assembly and sequestering GRAMD4 mRNA. This suppresses GRAMD4 translation and inhibits mitochondrial apoptosis. Targeting the integrated stress response with ISRIB restores GRAMD4 expression and sensitizes tumors to radiotherapy, revealing a translational control ...

Chitosan‑based nanoparticles with damnacanthal suppress CRM1 expression

Oncology Letters, 2018
Cancer is one of the leading causes of mortality worldwide. Phytochemicals may be promising anticancer agents given their various chemical structures and diverse biological activities. Damnacanthal (DAM) is a major bioactive component of Noni, which has been investigated previously as a cancer-preventive or chemotherapeutic agent.

Distinct RanBP1 nuclear export and cargo dissociation mechanisms between fungi and animals

eLife, 2019
Ran binding protein 1 (RanBP1) is a cytoplasmic-enriched and nuclear-cytoplasmic shuttling protein, playing important roles in nuclear transport. Much of what we know about RanBP1 is learned from fungi. Intrigued by the long-standing paradox of harboring

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

Journal 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 ...

Structural basis for cooperativity of CRM1 export complex formation [PDF]

Proceedings of the National Academy of Sciences, 2012
In eukaryotes, the nucleocytoplasmic transport of macromolecules is mainly mediated by soluble nuclear transport receptors of the karyopherin-β superfamily termed importins and exportins. The highly versatile exportin chromosome region maintenance 1 (CRM1) is essential for nuclear depletion of numerous structurally and functionally
