Drugging "undruggable" transcription factors with proteomics #chembio.

I just ran the first n=1 dynamic regulome experiment. On myself.

A 72-hour fast where we tracked all 4,000+ components of the genome regulatory 'software' to see how they respond

And over 30% changed, most never mentioned in fasting literature

Why does this matter?

It’s been a tough few weeks. My 10yo daughter was diagnosed with a very rare, aggressive cancer called interdigitating dendritic cell sarcoma (IDCS). I’m reaching out to identify clinicians/patients who have encountered pediatric IDCS or other (non-LCH) dendritic or histiocytic sarcomas cases.

Some diseases are too rare to be VC-fundable. Without grant funding, these patients get nothing—that’s unacceptable.

NIH grants fund our work on a rare cancer with no approved treatments. Every year, we pay out of pocket for a third-party audit to prove there’s no waste, no fraud—just science.

Does anyone know if the savings will be re-invested into more grants?

Or is this just slashing the overall budget of the NIH?
Flat 15% indirect costs across all grants (notes this will work because only 3 places - MIT, UMich, UAB - ever REFUSED a grant for lower than expected previous indirects). Impacts of this cut will presumably destroy research - current indirects are ~50%+

Cancer might be the most creative biologist - it's evolutionary "job" is to stress test every biological mechanism in our cells are see if promoted survival/fitness

Apparently tumors can tunnel into lymphocytes and dump their mutated mitochondria?

What a wild world
🧬 How Cancer Poisons the Immune System

New research uncovers how tumours transfer their mitochondria to immune cells, disrupting their function and weakening the body’s defences.

Could understanding this process lead to better cancer treatments?

This is the perspective I was waiting for after seeing all the new transcription factor footprinting papers 👇
There has been a couple of manuscripts released regarding transcription factor footprinting - or digital genomic footprinting (DGF) as we call it. I would like to put some of the claims, results and conclusions in context, since I have worked and published on this for ~15 years. 1/n

Re-upping this reply thread from last night. Drugs don't come from nowhere, folks. And we're not ripping off the NIH, either.
I think you're describing science, IMO. Everything is atop a foundation of basic research. An example: at a previous company, I worked on a series of small-molecule inhibitors of Hormone-Sensitive Lipase, a possible target for Type II diabetes and related conditions. (1/10)

For those of us who are not professional biologists, it can be daunting to hear about transcription factors, signaling pathways and non-coding RNA. But this poignant piece from @philipcball.bsky.social opened my eyes to how deep and essential these ideas truly are. nautil.us/how-life-rea...

Wow. Very impressive work with in vivo dTAG looking at KRAS G12V.

Lots more to learn with this technology, this is only the start. Congratulations Behnam and team!
🧪 Ready, set, degrade!

So proud to share our work in the @jclinical-invest.bsky.social, establishing a versatile approach for creating transgenic dTAG mice to degrade oncoproteins. We showcase that KRAS G12V degradation triggers antitumor immunity in lung cancer.

Spatial proteomics wins method of the year!

Our team at @talusbio.bsky.social isn't using IF-based spatial proteomics, TF-Scan does provide a surrogate of protein localization within the nucleus, with enough throughput to be useful for drug discovery.

I'm processing some DIA data using #DIANN and looking at the data using the Viewer (excellent addition!), many peptides don't look impressive (to say the least). Is it possible to be more stringent in assigning frags to precursors? #proteomics

Really cool pipeline, excited to play around with this (someday)
I've been working to make designing regulatory DNA that exhibits desired characteristics easier for everyone. With the following series of tools, you can go from a blank slate to designed edits in ~30 minutes using only a V100. That includes file downloading and model training.

Where would genomics be if the BAM/SAM file format was proprietary and Bamtools/Bowtie was closed source and prohibitively expensive? That's where the proteomics field is right now. Talus Bio's @willfondrie.com and a group of industry+academia leaders share -
This was a ton of fun to write with @ypriverol.bsky.social and all of the other authors 👏

Our goal was to share a vision of #OSS #proteomics for us to build toward, and propose some ways to get there 🚀

I’m blown away by how many folks contributed and how much it evolved beyond just my voice 🙌
