Jason Buenrostro stands behind a podium speaking to an audience.

Broad has launched the Biology of Adversity Project, led by
@jbuenrostro.bsky.social a 2023 @macfound.org fellow, to uncover how adverse life experiences can inflict molecular “scars” in the genome and body and increase risk of heart disease and other disorders. Learn more: broad.io/BAP

DNASE1L3 surveils mitochondrial DNA on the surface of distinct mammalian cells The extracellular space is a critical environment for discriminating self versus non-self nucleic acids and initiating the appropriate immune responses through signaling cascades to relay information ...

We’re excited to report work led by postdoc Jennifer Porat in the lab, finding that DNA accumulates on the surface of living cells and that the secreted extracellular protein DNASE1L3 can modulate its levels on B and T cells. With a new twist for ATAC-seq as well www.biorxiv.org/content/10.1...

Induction of menstruation in mice reveals the regulation of menstrual shedding During menstruation, an inner layer of the endometrium is selectively shed, while an outer, progenitor-containing layer is preserved to support repeated regeneration. Progress in understanding this co...

I’m thrilled to share my postdoc work and the first paper from the McKinley Lab! 🎉
@karalmckinley.bsky.social
We built the first transgenic model of menstruation in mice.
We used it to uncover how the endometrium organizes and sheds during menstruation. 🧪

My jaw dropped when I heard this presented earlier this year. Incredible.

Jason Buenrostro named core institute member at Broad An expert in epigenetics and longtime member of the Broad community, Buenrostro will focus on how life experiences can alter the epigenome and increase risk of disease.

Leading epigenetics researcher and longtime Broad member
@jbuenrostro.bsky.social has been named core institute member of the Broad. His lab will study how cells change in response to life experiences, and how those alterations affect health and disease.

One last thing - I am on the job market! My lab will extend this approach to decode resilient chromatin: adaptations in proteins/DNA that allow for survival in harsh environments. These hold the 🔑 to designing cells that thrive under stress, esp. as we push the limits of where we take them ❄️🚀🪐🌱9/9

Engineered histones reshape chromatin in human cells Histone proteins and their variants have been found to play crucial and specialized roles in chromatin organization and the regulation of downstream gene expression; however, the relationship between ...

Huge thanks to all co-authors and the inimitable @jbuenrostro.bsky.social for supporting this new direction - I got to think about evolution, engineering, chromatin biophysics, and modeling during the course of this project. For more, check out the preprint: www.biorxiv.org/content/10.1... 8/9

Excited to share my postdoc work, out on bioRxiv today! Histones package DNA into nucleosomes to form the building blocks of chromatin, but how modular and programmable is this system? 1/9

Had a super week filled with great science, curiosity and discussions at this year's Gordon Research Conference on Human genetics and genomics. Also fun when you get to give a talk the same day as your postdoc advisor @jbuenrostro.bsky.social

The 2025 Freeman Hrabowski Scholars | HHMI Freeman Hrabowski Scholars are outstanding early career faculty who have the potential to become leaders in their research fields.

Honored to be an HHMI FHS! Grateful to brilliant colleagues who push me to think deeply, and to my students whose curiosity & energy make the lab a joy.

My grad advisor said in genetic screens, you don’t get what you want—you get what you deserve. Hope we are deserving

To help people understand the importance of NIH, share what you’ve used their funding for (in easily understandable terms).

I’ll start: my NIH postdoc funding helped me develop and test AI tools that could identify skin cancer across diverse skin tones.

Hey Jeff, just to clarify, we performed a genome wide analysis across all cell types seen in BMMCs. The results are quantified in Figure 3c. There’s also more examples in Ext Figure 6. Feel free to shoot me a message if you’re interested, could be fun to discuss.

Multiscale footprints reveal the organization of cis-regulatory elements - Nature We developed PRINT, a computational method that identifies footprints of DNA–protein interactions from bulk and single-cell chromatin accessibility data across multiple scales of protein size.

Super excited to share our new study from the @jbuenrostro.bsky.social Lab in @nature.com! We developed a computational method for tracking transcription factor and nucleosome binding using single-cell ATAC-seq and deep learning.
