An Exportin-1-dependent microRNA biogenesis pathway during human cell quiescence. [PDF]
Significance Quiescence is a growth-arrested cellular state; genes involved in this process are finely regulated by several factors, including miRNAs. During miRNA biogenesis, Exportin-5 transports miRNA precursors from the nucleus to the cytoplasm.

C646 degrades Exportin-1 to modulate p300 chromatin occupancy and function. [PDF]
Molecular glues can induce proximity between a target protein and ubiquitin ligases to induce target degradation, but strategies for their discovery remain limited. We screened 3,200 bioactive small molecules and identified that C646 requires neddylation-dependent protein degradation to induce cytotoxicity.

Combined Targeting of Estrogen Receptor Alpha and Exportin 1 in Metastatic Breast Cancers. [PDF]
The majority of breast cancer specific deaths in women with estrogen receptor positive (ER+) tumors occur due to metastases that are resistant to therapy. There is a critical need for novel therapeutic approaches to achieve tumor regression and/or maintain therapy responsiveness in metastatic ER+ tumors. The objective of this study was to elucidate the

Cytoplasmic PML promotes TGF-β-associated epithelial–mesenchymal transition and invasion in prostate cancer [PDF]
Epithelial–mesenchymal transition (EMT) is a key event that is involved in the invasion and dissemination of cancer cells. Although typically considered as having tumour-suppressive properties, transforming growth factor (TGF)-β signalling is altered ...

Structural determinants of nuclear export signal orientation in binding to exportin CRM1
The Chromosome Region of Maintenance 1 (CRM1) protein mediates nuclear export of hundreds of proteins through recognition of their nuclear export signals (NESs), which are highly variable in sequence and structure.

Pharmacological treatment with inhibitors of nuclear export enhances the antitumor activity of docetaxel in human prostate cancer [PDF]
Background and aims: Docetaxel (DTX) modestly increases patient survival of metastatic castration-resistant prostate cancer (mCRPC) due to insurgence of pharmacological resistance. Deregulation of Chromosome Region Maintenance (CRM-1)/ exportin-1 (XPO-1)-

Nuclear exportin receptor CAS regulates the NPI-1-mediated nuclear import of HIV-1 Vpr. [PDF]
Vpr, an accessory protein of human immunodeficiency virus type 1, is a multifunctional protein that plays an important role in viral replication. We have previously shown that the region between residues 17 and 74 of Vpr (Vpr(N17C74)) contained a bona ...

The evolution of core proteins involved in microRNA biogenesis
Background MicroRNAs (miRNAs) are a recently discovered class of non-coding RNAs (ncRNAs) which play important roles in eukaryotic gene regulation. miRNA biogenesis and activation is a complex process involving multiple protein catalysts and involves the
