BH3 Mimetics and Senescent Breast Cancer Cells
2026-08-20
The 2020 reference study shows that chemotherapy-induced senescent breast cancer cells can remain biologically dangerous and may be selectively eliminated with BH3 mimetics. Its experiments connect TP53 status, BCL-XL or BCL-XL/MCL1 dependence, and treatment sequencing to improved tumor regression and survival in a preclinical model.

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.

Inositol Phosphates Activate Sin3L/Rpd3L HDACs
2026-08-15
Marcum and Radhakrishnan show that inositol phosphates stimulate HDAC1/2 activity in the Sin3L/Rpd3L complex through the SAP30 zinc finger, rather than a canonical SANT domain. The study also identifies RBBP4 as a constitutive activity-enhancing subunit, revealing layered regulation that can guide biochemical studies of chromatin-modifying complexes.

Single-Molecule Screening of Fast-Dissociating Antibodies
2026-08-13
Miyoshi and colleagues developed a semi-automated single-molecule TIRF assay that identifies specific, fast-dissociating monoclonal antibodies directly from hybridoma cultures. The resulting Fab probes supported multiplexable imaging and revealed rapid espin turnover within apparently stable actin cores of inner-ear stereocilia.
