Nuclear-Cytoplasmic Axis in Cancer: From Protein Mislocalization to Anticancer Drug Resistance.
Review in Oncology research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Nucleocytoplasmic transport (NCT) regulates the spatial distribution of proteins and RNA between the nucleus and cytoplasm. NCT dysregulation can mislocalize tumor suppressors, DNA-repair factors, transcription factors, and drug targets in cancer. In this review, we conceptualize NCT-dependent protein mislocalization as a spatial regulatory framework for anticancer drug resistance, rather than as a catalogue of transport components. We systematically discuss how nuclear pore complex (NPC) remodeling, transport-receptor imbalance, post-translational modification (PTM)-regulated cargo routing, signaling-NCT crosstalk, nuclear localization signal/nuclear export signal (NLS/NES) alterations, and tumor microenvironmental pressures jointly drive aberrant nucleocytoplasmic distribution. These processes can further regulate apoptosis, DNA-damage repair, oncogenic transcription, oxidative stress adaptation and drug-target accessibility, which ultimately promote drug tolerance and therapeutic resistance. We further distinguish clinically validated mechanisms from preclinical phenotypes and correlative observations. At present, the most advanced therapeutic evidence mainly supports exportin 1/chromosome region maintenance 1 (XPO1/CRM1) inhibition, particularly selinexor in selected hematologic malignancies; in contrast, strategies targeting the NPC, importins, PTM pathways, microenvironmental cues, or localization signals remain largely investigational. By integrating mechanistic, preclinical, translational, and clinical evidence, this review aims to synthesize current evidence on NCT-dependent protein mislocalization as a resistance-relevant axis and to highlight the need for cargo-specific biomarkers and rational combination strategies to translate this biology into anticancer therapy.
