Identifying a novel region in the Tembusu virus NS5 protein antagonizing type I interferon signaling

Journal of Virology
Numerous species in the genus Flavivirus have been identified to pose serious threats to public health. Most of them have developed evasion strategies to counteract antiviral activity triggered by type I interferon (IFN-I), making prevention and control ...

Putting things in place for fertilization: discovering roles for importin proteins in cell fate and spermatogenesis

Asian Journal of Andrology, 2015
Importin proteins were originally characterized for their central role in protein transport through the nuclear pores, the only intracellular entry to the nucleus.

Karyopherin β2B participates in mRNA export from the nucleus [PDF]

Proceedings of the National Academy of Sciences, 2002
Transport of macromolecules between the cell nucleus and cytoplasm occurs through the nuclear pores and is mediated by soluble carriers known as karyopherins (Kaps), transportins, importins, or exportins. We report that Kap β2B (transportin-2) forms complexes with the mRNA export factor TAP in the presence of RanGTP, as shown by ...

Multifaceted Roles of Chloroquines in Gastrointestinal Disorders and Beyond

Comprehensive Physiology, Volume 16, Issue 4, August 2026.
Chloroquine (CQ) and hydroxychloroquine (HCQ) modulate lysosomal activity and autophagy, suppressing gastrointestinal inflammation and reshaping pathogenic microbiota. These mechanisms alleviate inflammatory bowel disease, inhibit associated tumor growth, and provide benefits in certain autoimmune and viral conditions.

Are sperm capacitation and apoptosis the opposite ends of a continuum driven by oxidative stress?

Asian Journal of Andrology, 2015
This chapter explores the possibility that capacitation and apoptosis are linked processes joined by their common dependence on the continued generation of reactive oxygen species (ROS).

The karyopherin CRM1 is required for dendritic cell maturation

Immunobiology, 2010
Dendritic cells (DC) are the most potent antigen-presenting cells (APC) of the immune system and are specialized to activate T as well as B cell-dependent immune responses. Mature DC are characterized by expression of CD83, a surface molecule that has been postulated to be required for efficient DC activity.

Unveiling Gut Homeostasis Disruption in Sepsis: Towards an Integrated Mechanistic and Translational Roadmap

Cell Proliferation, Volume 59, Issue 8, August 2026.
Elucidating the contribution of gut‐organ axes will provide new insights for developing combined therapeutic strategies against sepsis‐associated multiple organ dysfunction. ABSTRACT Sepsis, a life‐threatening clinical syndrome precipitated by a maladaptive host response to infection, is associated with substantial morbidity and high mortality rates ...

Sperm DNA fragmentation, recurrent implantation failure and recurrent miscarriage

Asian Journal of Andrology, 2015
Evidence is increasing that the integrity of sperm DNA may also be related to implantation failure and recurrent miscarriage (RM). To investigate this, the sperm DNA fragmentation in partners of 35 women with recurrent implantation failure (RIF ...

Exosome‐Mediated Delivery of PROTACs for Targeted Protein Degradation in Cancer, Neurodegenerative, Infectious, and Inflammatory Diseases

Journal of Cellular and Molecular Medicine, Volume 30, Issue 15, August 2026.
ABSTRACT Proteolysis‐targeting chimeras (PROTACs) are heterobifunctional molecules that hijack the ubiquitin‐proteasome system to drive catalytic, sub‐stoichiometric degradation of disease‐associated proteins, offering a mechanistic advantage over occupancy‐driven inhibitors and access to ‘undruggable’ targets.

Functional consequences of necdin nucleocytoplasmic localization. [PDF]

PLoS ONE, 2012
BACKGROUND: Necdin, a MAGE family protein expressed primarily in the nervous system, has been shown to interact with both nuclear and cytoplasmic proteins, but the mechanism of its nucleocytoplasmic transport are unknown.
