Karyopherin α deficiency contributes to human preimplantation embryo arrest
Preimplantation embryo arrest (PREMBA) is a common cause of female infertility and recurrent failure of assisted reproductive technology. However, the genetic basis of PREMBA is largely unrevealed.

Reprogramming SREBP1-dependent lipogenesis and inflammation in high-risk breast with licochalcone A: A novel path to cancer prevention. [PDF]
What's new? Endocrine drugs repurposed from treatment protocols are the primary medications available for breast cancer (BC) prevention in at‐risk women. Adverse effects, however, significantly minimize uptake and prevention impact. Here, the authors investigated licochalcone A (LicA), a non‐endocrine anti‐inflammatory agent with reported hematologic ...

Karyopherin abnormalities in neurodegenerative proteinopathies [PDF]
Abstract Neurodegenerative proteinopathies are characterized by progressive cell loss that is preceded by the mislocalization and aberrant accumulation of proteins prone to aggregation. Despite their different physiological functions, disease-related proteins like tau, α-synuclein, TAR DNA binding protein-43, fused in sarcoma and mutant ...

KPNA5 Suppresses Malignant Progression of Ovarian Cancer Through Importing the PTPN4 Into the Nucleus. [PDF]
ABSTRACT Background Abnormal protein localization due to disrupted nucleoplasmic transport is common in tumor cells, but its mechanisms are not well understood. Nuclear pore complexes and nuclear transporter proteins are crucial for protein transport between the nucleus and cytoplasm.

Birth, Death, and Replacement of Karyopherins in Drosophila [PDF]
Nucleocytoplasmic transport is a broadly conserved process across eukaryotes. Despite its essential function and conserved mechanism, components of the nuclear transport apparatus have been implicated in genetic conflicts in Drosophila, especially in the male germ line. The best understood case is represented by a truncated RanGAP gene duplication that

Kapβ2 Reverses Sevoflurane-Induced Hydrogel Phase Transition of hnRNPA2/B1-SG in Hypoxic Primary Rat Hippocampal Neurons. [PDF]
Sevoflurane exacerbates hippocampal neuronal dysfunction under hypoxic conditions by inducing the cytoplasmic mislocalization of hnRNPA2/B1, which drives abnormal liquid–liquid phase separation (LLPS) and subsequent irreversible hydrogel transition of hnRNPA2/B1‐containing stress granules (SGs).

Ebolavirus Species-Specific Interferon Antagonism Mediated by VP24
Members of the Ebolavirus genus demonstrate a marked differences in pathogenicity in humans with Ebola (EBOV) being the most pathogenic, Bundibugyo (BDBV) less pathogenic, and Reston (RESTV) is not known to cause a disease in humans.

Several aggregation-prone RNA-binding proteins, including FUS, EWS, TAF15, hnRNP A1, hnRNP A2, and TDP-43, are mutated in neurodegenerative diseases. The nuclear-cytoplasmic distribution of these proteins is controlled by proteins in the karyopherin family of nuclear transport factors (Kaps). Recent studies have shown that Kaps not only transport these

The Ebola Virus Interferon Antagonist VP24 Undergoes Active Nucleocytoplasmic Trafficking
Viral interferon (IFN) antagonist proteins mediate evasion of IFN-mediated innate immunity and are often multifunctional, with distinct roles in viral replication.

Karyopherins in nuclear pore biogenesis [PDF]
The mechanisms that govern the assembly of nuclear pore complexes (NPCs) remain largely unknown. Here, we have established a role for karyopherins in this process. We show that the yeast karyopherin Kap121p functions in the targeting and assembly of the nucleoporin Nup53p into NPCs by recognizing a nuclear localization signal (NLS) in Nup53p.
