Could not resist re-sharing our paper to show off the beautiful cover art from Drs. Kelly Cupp-Sutton and Mozhgan Boroumand!
Huge shoutout to Drs. Si Wu and Kellye Cupp-Sutton who were an enormous help in our first top-down analysis! #TeamMassSpec, #senescence, #aging, #geroscience, #proteomics, #TopDownProteomics n/n
A key observation is the definition of SASP highly depends on control conditions. We propose that comparing with multiple controls representing different 'non-senescent' states (e.g. proliferating cells, quiescent cells,..) are best to identify robust senescence-specific proteins. 5/n
Several proteoforms emerged as unique to senescent cells versus either control condition. Notably, all multi-phosphorylated forms of HMGA2 were elevated in the SASP. Perhaps due to P-Ser flanking the nuclear localization sequence, similarly to the related HMGB1 protein, a well known SASP. 4/n
Topdown proteomics enabled us to identify 52 proteoforms mapping to 38 known SASP proteins previously reported in our bottom-up DIA SASP Atlas study. Additionally, we identified 41 proteoforms mapping to 29 proteins not previously reported. 3/n
We performed quantitative top-down secretomics on senescent, proliferating and quiescent cells to identify senescence-specific proteoforms. We used a combination of ToPIC suite (for IDs) and Biopharma Finder (for the areas of mass features) and combined the outputs for proteoform quant. 2/n
Happy to share our lab’s latest paper in Analytical Chemistry! pubmed.ncbi.nlm.nih.gov/41084887/
Our first foray into top-down proteomics led by Dr. Mozhgan Boroumand sought to identify proteoforms of the Senescent Secretome (SASP)-a stepping stone toward human proteoform biomarker candidates. 1/n
Super exiting! What could be better than winning an award? Winning in the same year as a former UW trainee (Nate), one of my closest colleagues (Bill), and two good friends (Neil and Lingjun). See you all in St. Louis!

Nice congrats! I was wondering what to call BlueSky tutorials
@bradolinger.bsky.social called it “blueprint” and I liked that…
Here we go, my first skeet-torial(?) on Bluesky for my first paper from @talusbio.bsky.social !

This preprint describes our scalable, mass spec-based method for measuring which (and how many of them) proteins are interacting with DNA.

Thanks to all who contributed to the study! Including support from the NIA Intramural Research Program, NIH SenNet Common Fund Grant, and Hevolution Foundation. Thanks to the Seer team who were extremely responsive and helpful.

We hope this workflow enables other labs to perform comprehensive proteomic studies in mice, where it was not previously possible due to volume and dynamic range limitations.

We demonstrate the method's potential to detect aging /phenotype associated changes in serum. We observed completely different changes in blood at several ‘old’ ages, such as 24 months (old) and 30month (geriatric), reinforcing the importance of including multiple timepoints in aging studies
4/n
MS studies notably miss cytokines. A targeted mouse cytokine panel (O-link) on just 1 uL serum enabled us to quantify an additional 39 proteins not detected by MS (e.g. IL6), suggesting strong complimentary to the MS workflow. As expected, the majority of the cytokines increased with age.
3/n
Led by @bradolinger.bsky.social and Amit Dey – in 20uL serum we detected nearly 4000 proteins using the Proteograph workflow (4+ fold improvement) & demonstrated its consistency and accuracy w/ an 'LFQ-Bench-like' study. All on the Q-Exactive HF, so no need for the new fancy stuff.
2/n
Where are the deep proteomic studies of mouse blood? We rarely see them because doing proteomics in mouse blood is challenging due to volume limitations and dynamic range.
I’m pleased to share our latest preprint showing a workflow that overcomes these challenges.

We've learned a lot more about the principal drivers of age-related diseases in the past few weeks. And the leads to a unified model to put it all together. (open-access)
