1/7 Excited to talk about some of the amazing science we discovered about #meningioma #biology at @LabRaleigh. Humbled to be the lead author on this massive, collaborative project. It was a herculean effort only possible thanks to the efforts of so many people! #braintumor #BTSM
✨ OUT NOW @NatureGenet
📰 Meningioma DNA methylation groups identify biological drivers and therapeutic vulnerabilities🧠

So happy to share this paper investigating evolutionarily-conserved perivascular #meningioma stem cells and radiation resistance! @abrarc @ElizabetsCrouch @NeurosurgUCSF @UCSFCancer @UCSF
Now online in @CD_AACR: Perivascular NOTCH3+ Stem Cells Drive #Meningioma Tumorigenesis and Resistance to Radiotherapy - by @abrarc, Martha Cady, @LabRaleigh, and colleagues doi.org/10.1158/2159-8290.CD… @UCSF

ProPublica continues their incredible work exposing the vile underbelly of health insurance companies. Received a denial? Ask for your claim file.
Lee Mazurek had been on medication to keep his chronic disease at bay for nine years when a @Cigna employee flagged his case for review.
The company estimated it could save $98,000+ if he switched parts of his treatment plan. Then came the denial. 🧵👇👇

It’s dissertation day in @LabRaleigh!! Congratulations Dr. @vikdagg!! @NeurosurgUCSF @UCSFCancer @UCSF
Super excited for this next step in my physician-scientist journey! And incredibly grateful for all the people who have supported me along the way. Wouldn't be here without my time at @LabRaleigh.
We are SO excited to announce the results of the 2023 Match and to introduce you to our HROP class of 2028!! #Match2023 #MatchDay #radonc #MedTwitter

2 #schwannoma pre-prints! @LabRaleigh and lead author @sjohnliu identify epigenetic mechanisms underlying schwannoma molecular groups: biorxiv.org/content/10.1101/…. Meanwhile, @AlbertHKimMDPhD finds nerve injury-like cell states distinguish schwannoma cells: biorxiv.org/content/10.1101/….

Excited to finally be able to share my work post peer-review on inflammatory reactive astrocytes! nature.com/articles/s41593-0…

Today, we’re introducing a new model that eliminates accept/reject decisions.
By publishing every paper with eLife reviews as a Reviewed Preprint, we plan to restore autonomy to authors, ensuring that they will be judged by what, not where, they publish. elifesciences.org/inside-eli…

#meningioma has many grouping systems but consensus architecture is needed for new treatments/trials. Very happy to collaborate with @wenyalindabi @akashjp330 @sahm_lab @StephenTMagill on this paper! @abrarc @WilliamCChen1 @NeurosurgUCSF @UCSFCancer academic.oup.com/neuro-oncol…

Our collaboration with the Schmitt lab @MSK_RadOnc is online! Happy to have helped with some Hedgehog things and some bioinformatic things with @DrHVasu to elucidate how lncRNAs can influence brain cancer stem cells. pnas.org/doi/epdf/10.1073/pn…

Federally funded research should be freely accessible to the American public. From environmental justice to cancer breakthroughs to more sustainable farming, immediate access to America’s research jumpstarts innovation everywhere.

Just over a year ago, I read a paper which showed that when private equity buys nursing homes, death rates go up 10%. I was a med student at Stanford, but I halted my studies to investigate. Today, that investigation was published in @NewYorker newyorker.com/news/dispatch/…
This is HUGE! Major win for #OpenAccess
BREAKING: White House issues new policy that will require, by 2026, all federally-funded research results to be freely available to public without delay, ending longstanding ability of journals to paywall results for up to 1 year. Coverage coming on @ScienceInsider.

Very happy to share our pre-print reporting interactions between NF1 and NF2 driving Schwann cell tumor de-differentiation and treatment resistance. Lead author @DrHVasu of the eponymous Vasudevan Lab at @NeurosurgUCSF @UCSFCancer in the driver's seat! researchsquare.com/article/r…

.@theNCI writes that classifying #meningioma tumors by their DNA methylation patterns could identify tumors most likely to recur as well as potential new treatments. Learn more about this research, including work led by @LabRaleigh @abrarc @StephenTMagill:
