St. Jude scientists identified a direct role for PARP1 in chromatin remodeling, revealing for the first time how the protein partially disassembles nucleosomes to make damaged DNA accessible for repair. The findings could lead to more targeted PARP1 inhibitors and potentially reduce treatment toxicity. https://t.co/YWh6PuqrsW
Excited to share that our work is now published in Molecular Cell! We provide the first direct evidence for a role of hexasomes in DNA repair! Wonderful collaboration with @LabHalic, the Shelat labs, and St. Jude Imaging. https://t.co/TDbM38WDSJ
@masonbgrant@JExpMed Thank you for your message! We don't know formally because we didn't test fibrolamellar HCC cells, but it could be. If interested to chat more DM me!

TLDR: a genetically-defined group of osteosarcoma is sensitive to the EP300 PROTAC JQAD1, due to a balance between degradation and resynthesis by the ribosome. Read on for deets...
New research published in @JExpMed from @DanaFarber’s @JunQiLab and collaborators reveals that AKT inhibitors synergize with EP300 degraders to suppress osteosarcoma growth in vitro and in vivo. These agents positively combine across cancer cells in a manner dependent on control of protein synthesis.

Researchers identified a potential therapeutic vulnerability in a subset of osteosarcoma. In preclinical models, combining EP300 degradation with AKT inhibition slowed tumor growth and prolonged survival. The findings suggest a potential path toward more personalized treatment. https://t.co/mti5ctijzY
This work sets the stage for future work testing more drug-like EP300 degraders with AKT inhibitors in osteosarcoma and indeed, across many, many other types of cancer.
Competitive candidates have a computational background, as described in the application post below.

This position bridges the brilliant Brian J. Abraham lab computation with experimentation in the Adam Durbin lab @StJudeResearch.
How “specific” are the inhibitors we use? In @nchembio, Sterling and Holtsmark et al reveal a dual inhibitory role for the clinical agent zavondemstat! Findings with implications for target and patient selection in trials, discussed by Drs Ali Nezhady and McKay-Corkum.
