Insights

Selective inhibitors of nuclear export (SINE) target Exportin-1 (XPO1) to disrupt cancer cell growth. The drug KPT-330 (selinexor) shows promise in early trials for various cancers.

Area of Science:

  • Oncology
  • Molecular Biology
  • Drug Development

Background:

  • Nucleo-cytoplasmic transport is crucial for cellular function and its dysregulation is implicated in cancer.
  • Exportins, particularly Exportin-1 (XPO1/CRM1), are key regulators of protein nuclear export.
  • XPO1 mediates the transport of over 200 proteins, influencing cell proliferation and survival.

Purpose of the Study:

  • To review the development and therapeutic potential of selective inhibitors of nuclear export (SINE) drugs.
  • To highlight the role of XPO1 as a therapeutic target in oncology.
  • To discuss the clinical progress of KPT-330 (selinexor) in treating malignancies.

Main Methods:

  • Literature review of studies on nucleo-cytoplasmic transport, XPO1, and SINE compounds.
  • Summary of preclinical and clinical data for SINEs, focusing on KPT-330.
  • Analysis of the mechanism of action of XPO1 inhibitors.

Main Results:

  • Selective inhibitors of nuclear export (SINE) represent a novel class of anticancer agents.
  • KPT-330 (selinexor) has demonstrated promising activity in early-phase clinical trials.
  • SINEs target the XPO1-mediated nuclear export pathway, impacting cancer cell viability.

Conclusions:

  • Targeting XPO1 with SINEs offers a promising therapeutic strategy for cancer treatment.
  • KPT-330 (selinexor) is an orally available agent with potential applications in both solid tumors and hematological malignancies.
  • Further clinical investigation is warranted to establish the efficacy and safety of SINEs in diverse cancer types.

Nuclear Export01:42

Nuclear Export

The nucleus restricts several proteins within and allows others to pass. The restricted proteins possess a nuclear retention sequence or NRS, anchoring them to the nuclear lamins and preventing their transport to the cytosol. The non-restricted proteins, after their synthesis, are transported to their site of action, such as the cytosol or other organelles, with the help of nuclear export signals or NES.
NES are of three types- the canonical 10-residue long leucine-rich signal and other...

Nuclear Protein Sorting01:34

Nuclear Protein Sorting

Nuclear protein sorting is the selective trafficking of histones, polymerases, gene regulatory proteins into the nucleus and exporting RNAs and ribosomes to the cytosol. It is a tightly controlled process that regulates gene expression within a cell.
Proteins targeted to the nucleus carry nuclear localization signals or NLS recognized by import receptors in the cytosol. Similarly, proteins with nuclear export signals are recognized by export receptors. Import and export receptors are...

Nuclear Export of mRNA02:31

Nuclear Export of mRNA

Before mRNAs are exported to the cytoplasm, it is crucial to check each mRNA for structural and functional integrity. Eukaryotic cells use several different mechanisms, collectively known as mRNA surveillance, to look for irregularities in mRNAs. Irregular or aberrant mRNA are rapidly degraded by various enzymes. If a defective mRNA escapes the surveillance, it would be translated into a protein which would either be non-functional or not function properly. One of the primary irregularities in...

Regulation of Nuclear Protein Sorting01:45

Regulation of Nuclear Protein Sorting

Nuclear protein sorting regulates nucleus composition and gene expression, crucial for determining the fate of a eukaryotic cell. Hence, the entry and exit of molecules across the nuclear envelope is a tightly controlled process. Nuclear protein sorting can be inhibited by one of the following ways: 1) masking cargo signal sequences, 2) modifying the nuclear receptor's affinity for cargo, 3) controlling the nuclear pore size, 4) retaining the cargo during its transit to the cytosol or the...

Nuclear Localization Signals and Import01:46

Nuclear Localization Signals and Import

Proteins targeted to the nucleus carry short stretches of amino acid sequences called the nuclear localization signal or NLS. Classical nuclear localization signals are of two types: monopartite and bipartite NLS. Monopartite classical NLS (cNLS) consists of a single cluster of 4-8 amino acids. Bipartite cNLS consists of two clusters of  2-3 amino acids and a 9-12 residue long proline-rich linker bridging the two clusters. Signal clusters are rich in positively charged amino acids such as...
