DEV VP26, Actin–Myosin II, and Viral Proliferation
2026-09-09
A 2025 study combined VP26 interactomics with genetic and pharmacological perturbation to identify the host actin–myosin II network as a determinant of duck enteritis virus proliferation. Its strongest mechanistic evidence implicates MYH9 and shows that disrupting actin assembly or myosin II activity lowers viral output, while also defining important limits for cross-system interpretation.

mTORC1 Oscillations Coordinate Cell-Cycle Entry
2026-09-04
Joshi et al. show that mTORC1 activity oscillates across the cell cycle, reaching its highest level during S/G2 and its lowest level during mitosis and G1. The study links this metabolic rhythm to interphase progression, Chk1/Wee1-dependent mitotic entry, and phase-specific sensitivity to autophagy induction.
