RAM function is dependent on Kapβ2-mediated nuclear entry [PDF]

open access: yes, 2014
Eukaryotic gene expression is dependent on the modification of the first transcribed nucleotide of pre-mRNA by the addition of the 7-methylguanosine cap.

Viruses Challenge Selectivity Barrier of Nuclear Pores

open access: yesViruses, 2013
Exchange between the nucleus and the cytoplasm occurs through nuclear pore complexes (NPCs) embedded in the double membrane of the nuclear envelope. NPC permeability barrier restricts the entry of inert molecules larger than 5 nm in diameter but allows ...

Developmental regulation of the heat shock response by nuclear transport factor karyopherin-α3 [PDF]

open access: yes, 2001
During early stages of Drosophila development the heat-shock response cannot be induced. It is reasoned that the adverse effects on cell cycle and cell growth brought about by Hsp70 induction must outweigh the beneficial aspects of Hsp70 induction in the

Analysis of the effects of importin α1 on the nuclear translocation of IL-1α in HeLa cells

open access: yesScientific Reports
Interleukin-1α (IL-1α), a cytokine released by necrotic cells, causes sterile inflammation. On the other hand, IL-1α is present in the nucleus and also regulates the expression of many proteins.

Simple biophysics underpins collective conformations of the intrinsically disordered proteins of the Nuclear Pore Complex [PDF]

open access: yes, 2016
Nuclear Pore Complexes (NPCs) are key cellular transporter that control nucleocytoplasmic transport in eukaryotic cells, but its transport mechanism is still not understood.

Adenylosuccinate Synthase 1 Deficiency Improves Energy Metabolism by Promoting Adipose Tissue Re‐esterification via Glycerol Kinase Upregulation

open access: yesAdvanced Science, Volume 13, Issue 1, 5 January 2026.
Working model of Adss1‐mediated regulation of energy metabolism in adipose tissue. In beige adipocytes, Adss1 interacts with HDAC3 in the cytoplasm, and its loss reduces nuclear HDAC3 while increasing cytosolic fractions. This redistribution suppresses HDAC activity and enhances H3K27 acetylation at the Gk promoter, leading to transcriptional ...

Lactylation Enhances the Activity of Lactate Dehydrogenase A and Promotes the Chemoresistance to Cisplatin Through Facilitating DNA Nonhomologous End Junction in Lung Adenocarcinoma

open access: yesAdvanced Science, Volume 13, Issue 3, 14 January 2026.
Lactylation, linked to glycolysis, is poorly understood in regulation. It is found that LDHA is lactylated at Lys81/Lys318 by AARS1, boosting its activity and cellular lactylation via positive feedback in LUAD. Lactylation regulates NHEJ‐related proteins; their delactylation impairs NHEJ and increases cisplatin sensitivity, offering anticancer insights.

RNA interference approaches for treatment of HIV-1 infection. [PDF]

open access: yes, 2015
HIV/AIDS is a chronic and debilitating disease that cannot be cured with current antiretroviral drugs. While combinatorial antiretroviral therapy (cART) can potently suppress HIV-1 replication and delay the onset of AIDS, viral mutagenesis often leads to

GSH as an A‐A Type Allosteric Activator of PKM2: Modulating Cancer Cell Homeostasis and Ferroptosis Susceptibility

open access: yesAdvanced Science, Volume 13, Issue 5, 27 January 2026.
Glutathione (GSH) defines oxidative balance, but can it directly tune central metabolism? The research reveals that GSH binds and potently activates pyruvate kniase M2 (PKM2), rewiring glycolysis and dictating ferroptosis sensitivity. Combining GSH depletion with PKM2 activation triggers mitochondrial damage and lipid peroxidation, profoundly ...
