NR4A2 & RGS16 promoters support delivery of cytokines (e.g. IL-12) directly to the tumor site, leading to enhanced antitumor efficacy and long-term survival of mice in both syngeneic and xenogeneic models @nature.com @paulbeavis4.bsky.social

Someone awesome in my circle shared some terrific news with me today but was hesitant to do so because of all that is going on in the science world.

It may appear insensitive that you are celebrating when other colleagues are struggling but I entreat you to celebrate & share good news. 1/

The fate of T cells, such as seen in exhausted T cells, is tied to nutrients. This introduces the potential of therapies directed at keeping T cell identity and function intact. (And the infamous Krebs cycle makes a comeback to my brain)

ChIP-DIP maps binding of hundreds of proteins to DNA simultaneously and identifies diverse gene regulatory elements - Nature Genetics ChIP-DIP (ChIP done in parallel) is a highly multiplex assay for protein–DNA binding, scalable to hundreds of proteins including modified histones, chromatin regulators and transcription factors, offe...

Gene regulation involves thousands of proteins that bind DNA, yet comprehensively mapping these is challenging. Our paper in Nature Genetics describes ChIP-DIP, a method for genome-wide mapping of hundreds of DNA-protein interactions in a single experiment.
