HBsAg, TBK1, and Autophagy in Chronic HBV
2026-08-18
A 2025 Cell Death and Disease study identifies TBK1 as a mechanistic branchpoint exploited by hepatitis B surface antigen (HBsAg). HBsAg enhances TBK1 dimerization while uncoupling TBK1 from IRF3, thereby suppressing type I interferon and promoting incomplete autophagy that supports HBV persistence.

CDK4/6 and BET Synergy in Pancreatic Cancer
2026-08-17
Gu et al. show that palbociclib alone can restrain pancreatic tumor-cell proliferation while unexpectedly enhancing migration, invasion, and epithelial-to-mesenchymal transition. Combining CDK4/6 inhibition with the BET inhibitor JQ1 produced synergistic tumor growth suppression by counteracting GSK3β-mediated Wnt/β-catenin signaling and its interaction with TGF-β/Smad pathways.

Doxycycline as a Translational Research Lever
2026-08-17
Doxycycline is more than a familiar tetracycline antibiotic: its antimicrobial activity, metalloproteinase inhibition, and context-dependent antiproliferative effects make it a versatile translational research compound. This article connects those mechanisms with targeted nanomedicine findings while clearly separating evidence established for doxycycline from hypotheses inspired by a recent peptide-delivery study.

Measuring Cancer Drug Responses In Vitro
2026-08-15
Hannah R. Schwartz’s dissertation distinguishes relative viability from fractional viability, showing that growth inhibition and cell killing are related but non-equivalent dimensions of an in vitro drug response. Its central practical contribution is a measurement framework that incorporates response magnitude, biological composition, and timing before assigning mechanistic meaning to drug sensitivity.
