NS1-BP–NXF1 Export of Influenza M mRNAs
2026-08-25
The reference study identifies NS1-BP as a host factor that competes with influenza NS1 for NXF1 and helps route alternatively spliced M1 and M2 mRNAs to the cytoplasm. Its biochemical and cell-biological evidence supports a stage-specific export model in which NS1-BP, NXF1, and TREX-2-associated factors remain together until nuclear pore docking, clarifying how influenza virus overcomes NS1-mediated host mRNA export inhibition.

Selective Autophagy Balances IRF3 Antiviral Signaling
2026-08-24
Wu and colleagues show that CALCOCO2/NDP52-mediated selective autophagy limits IRF3 stability in a virus load-dependent manner, while PSMD14 preserves basal IRF3 through deubiquitination. The study provides a mechanistic explanation for how cells sustain type I interferon production without allowing prolonged IRF3 activity to intensify immune damage or suppression.

Trelagliptin and Insulin Resistance in Adipocytes
2026-08-22
The reference study investigated how trelagliptin succinate affects insulin resistance in differentiated 3T3-L1 adipocytes, linking DPP-4 inhibitor treatment to IRS-1/AKT signaling, GLUT4 membrane localization, glucose uptake, and adipokine regulation. Its main contribution is a cellular mechanism for trelagliptin’s metabolic effects, while its in vitro design leaves questions about dose dependence, human adipose tissue, and in vivo translation.

CX-5461 Triggers Mitotic Catastrophe in Cervical Cancer
2026-08-18
The reference study identifies a mechanism by which the RNA polymerase I inhibitor CX-5461 suppresses cervical cancer cell growth: Pol I inhibition is linked to ATM/ATR-dependent DNA damage, premature mitotic entry, and mitotic catastrophe. The findings also indicate that CX-5461 can enhance cisplatin sensitivity, providing a mechanistic basis for investigating combination strategies in recurrent or platinum-resistant disease.

MVC Uses RhoA/ROCK1 to Disrupt Tight Junctions
2026-08-17
Ren and colleagues identify a direct interaction between MVC VP2 and ROCK1 and show that early RhoA/ROCK1/MLC2 activation disrupts tight junction organization in canine cells. The study links cytoskeletal contraction to Occludin exposure and viral entry, providing a mechanistic framework for investigating host-directed anti-MVC strategies.
