Extremely happy to be awarded the Sidney & Joan Pestka Post-graduate award!
Thank you @cytokinesociety.bsky.social and all my mentors, colleagues and collaborators throughout my career so far!

The integrated stress response fine-tunes stem cell fate decisions upon serine deprivation and tissue injury Novak et al. discover that dietary serine impacts whether hair follicle stem cells (HFSCs) prioritize hair growth or skin repair after injury. HFSCs gauge metabolic stress using the ISR and accelerate re-epithelialization while delaying hair regeneration when serine-deprived. These findings suggest new metabolic and pharmacologic strategies to enhance wound repair.

Intracellular metabolic gradients dictate dependence on exogenous pyruvate Nature Metabolism - Jackson et al. provide insight into how metabolic adaptations that accompany cell state transitions drive reliance on exogenous nutrient availability, focusing on pyruvate as a...

I'm excited to share our latest story from the
@lydiafinley.bsky.social lab, where we show that it's not just whether cells take up nutrients that matters, but how and where those metabolites are used. Out now in @naturemetabolism.bsky.social: rdcu.be/ejFTs 1/

Postdoc Night Science NYC! Next session is Friday 4-6pm at MSK, to learn and practice the creative scientific process! The topic this time is the import/export of ideas. Yael David join us too! @davidlabmsk.bsky.social
Limited spots: docs.google.com/forms/d/12bB... @kelseymonson.bsky.social

All the best for your next steps, Ushma!!

Postdoc Night Science NYC March 14th, 2025 4:00-6:00pm @ Memorial Sloan Kettering CC ZRC 138 On the importing & exporting of ideas across fields

Postdoc Night Science NYC is coming to @mskcancercenter.bsky.social!
#MSKPostdocs, come join Drs. @itaiyanai.bsky.social and @kelseymonson.bsky.social to explore and practice the creative scientific process. In this session, they will discuss how to import and export ideas across different fields.

Congrats again!!

Cooperative nutrient scavenging is an evolutionary advantage in cancer Nature - Nutrient-starved tumour cells cooperate by secreting aminopeptidases that digest oligopeptides in the microenvironment, creating a shared pool of free amino acids.

First: I apologize for never coming here and now doing so only to brag 😬
Second: I am very proud of the people in our lab. We are a small group in a Bio department and this work took an enormous amount of effort from every one here.

I’m really proud to announce the 2025 Cancer Metabolism Showcase and Workshop, May 5th and 6th, 9:30 AM - 3 PM EST. This year, our Keynote Speaker is Dr. Jeffrey Rathmell from VUMC.

I'm excited to come together, talk science, and support researchers in our field.

Super proud of my bench mate and her work on differential metabolic dependencies in pediatric rhabdo; now online at @biorxiv-cancer.bsky.social - @katrinaparas.bsky.social who’s going to help me with cloning when you’re gone?!

Our latest preprint identifies (targetable!) metabolic programs intrinsic to different cancer cell states in rhabdomyosarcoma, out just in time for @katrinaparas.bsky.social's thesis defense tomorrow!

I hope you will join @lydiafinley.bsky.social and me for two days of great science on metabolic support of development and cell fate. Deadline for scholarships and short talk abstracts is Feb. 6.

What if we could look at a human tissue image🔬and quantify its biological age?🧬 And how could we get the same insights without collecting the tissue sample? In our new @biorxivpreprint, we create "tissue clocks" ⏳to do just that! www.biorxiv.org/content/10.1... 📝 #aging #tissue thread below⬇️

How do past viral infections influence future viral diseases? We found that SARS-CoV-2 recovery protected from severe influenza A virus disease. But how come? There seemed to be some antigen-independent immunological memory going on..
