New work from my team, identifying drug targets in M. abscessus. Pre-print posted here: www.biorxiv.org/content/10.6...

Looking forward to the biannual #CBP2025 conference @ohsunews.bsky.social starting this week! incredible line up of speakers, including keynotes @mbogyo.bsky.social, @christhechang.bsky.social, and Nancy Carrasco. www.ohsu.edu/school-of-me...

Excellent study by first author @andriigorelik.bsky.social in @ahellab.bsky.social showing how DTX2 tunes AHR transcription and stability, offering deeper insight into ADP-ribosylation–ubiquitylation crosstalk.

Talazoparib stands out for its strong potency and DNA "trapping" in certain cancers, but why this happens wasn’t clear. A new preprint from first author Jin Cai in the @ladurner.bsky.social lab, together with Ben Black’s team, address this in a new preprint: www.biorxiv.org/content/10.1...

Agreed! This review thoughtfully and comprehensively dives into the world of HPF1. The questions at the end are on point!

Excited to share the peer-reviewed version of our work, now online in @embojournal.org! Big thanks to our reviewers and @hvodermaier.bsky.social for facilitating this process. Looking forward to continuing this fun collaboration with @michaelnadbio.bsky.social! www.embopress.org/doi/full/10....

A few years back we discovered a dual hybrid protein modification composed of ADP-ribose dinucleotide and ubiquitin (ADPr-Ub). Now we reveal that ADPr-Ub can be further ubiquitinated by the E3 ubiquitin ligase RNF114! www.nature.com/articles/s41... www.science.org/doi/10.1126/...

An amazing paper from van der Heden and Ahel groups! They use clever chemistry to identify RNF114 as a dual ADP-ribose-Ubiquitin reader involved in the DNA damage response! Congratulations to first authors Max, @chatrin-c.bsky.social and Rishov. Happy to have a small contribution in this story

Cool new paper from Matic lab showing that MARUbylation occurs on serines in response to DNA damage.

Check out this story about my OHSU colleague’s work describing a previously unknown critical neurological function for dystroglycan with important implication for neuromuscular disease.

Check out this great review on the fascinating field of renal interoception by our newest faculty member, @rose-hill.bsky.social!

Today they have crossed a deep red line. We, the people, must hold the president and his appointees accountable for this outrageous abuse against American liberty.

Excellent paper by first author @andriigorelik.bsky.social and @ahellab.bsky.social team that uncovers new insights into PARP7-AHR biology in PARP7i-sensitive cancer cells.

Please join the chorus of voices, including my own, in support of the talented, hardworking and dedicated scientists and staff at NIH. They serve their country by deploying their training and skills to improve the health and quality of life of all Americans 🙏 🇺🇸

@doc-jlmeier.bsky.social got my swag, and now I’m ready for some good science and basketball at the #2025BioorganicGRC. It’s been too long!

Lots of exciting work to do at this interface between #ubiquitin and #ADP-ribosylation! In the coming months, @michaelnadbio.bsky.social and I hope to be recruiting new team members to explore this space. Here is a thread of other exciting opportunities to check out!

Cool new manuscript by @tafesselab.bsky.social and colleagues revealing a fascinating connection between SARS-CoV-2 infection and host lipid metabolism. Perhaps this opens up new therapeutic opportunities? Congrats!

A postdoc position is available in our lab to study ADP-ribosylation and ubiquitylation signalling! We are looking for someone with experience in structural biology and biochemistry. The application deadline is June 20th. my.corehr.com/pls/uoxrecru...

Awesome review by Braden Lobingier and colleagues on ways to study compartmentalized GPCR signaling.

I have had the privilege to train many chinese students over many years. They enriched our lives and did great science. Many are still here and contribute to the US scientific enterprise. The push to revoke student visas is cruel and unnecessary. We must push back. www.npr.org/2025/05/28/g...

Another awesome collaboration with @jnpruneda.bsky.social and team providing deeper insight into the writers of MARUbylation. Check out thread 👇!

You know ubiquitination, you may know ADP-ribosylation... But ubiquitination of ADP-ribose aka MARubylation??? Read our brief spotlight on @michaelnadbio.bsky.social and @jnpruneda.bsky.social 's recent work describing this dual modification here!

Great article on the importance of humor by the late Pope Francis: “Irony is a medicine, not only to lift and brighten others, but also ourselves, because self-mockery is a powerful instrument in overcoming the temptation toward narcissism.” www.nytimes.com/2024/12/17/o...

Interested in starting your cancer research career in London ?We're looking for a Scientific Officer to support our work on synthetic lethality in triple negative and BRCA1/2 mutant cancers. Ideal job for a new graduate who wants to kick start their research career. jobs.icr.ac.uk/vacancies/12...

this week 20 years ago, Nature published two seminal papers showing for the first time that BRCA-mutant cells were selectively sensitive to PARP inhibitors, paving the way for clinical trials and approval of PARP inhibitors for patients with BRCA-mutant ovarian and breast cancers, and beyond.

Great news: NIH postbac program is recruiting again! If your grad school plans were affected by program cutbacks or admissions freezes this year I highly encourage you to apply, this could be a perfect opportunity. Please repost. www.training.nih.gov/research-tra...

Another great addition to the PARP/ADP-ribosylation field! Leung lab shows that PARP14-mediated ADP-ribosylation promotes the formation of non-canonical p62 bodies. Will be exciting to figure out their functional role.

Today there are two symposia at the ACS in honor of Peter Dervan (11AM & 5PM). Although I can't be there to celebrate, I wanted to share a few reflections on my time in his lab (2009-2012) and the impact he's had on me as a scientist.

Excellent article by Dr. Jonathan Cole highlighting impact of academic freedom and fundamental research on advancing human health and economic prosperity, and the urgency of safeguarding them. www.nytimes.com/2025/03/24/o...

New research from the @jnpruneda.bsky.social and @michaelnadbio.bsky.social labs: In this collaborative work, the groups show that ubiquitin is directly linked to mono-ADP-ribose modifications on proteins, a process called “MARUbylation". www.embopress.org/doi/full/10....

New Paper💡PARP enzymes regulate ADP-ribosylation, a protein modification linked to cancer, infections & neurodegeneration. But it comes with two forms—MARylation (single) & PARylation (multiple). Meet dELTA-MS, a mass spec method that identifies both in one experiment! pubs.acs.org/doi/full/10....

As federal funding for research is uncertain, we need to diversify funding sources for our PhD students. Here is a comprehensive list of >160 PhD fellowships and funding opportunities, mostly from private foundations and scientific societies. Download it here: research.jhu.edu/rdt/funding-...

Grateful for all the people mobilizing across the US and the world for #StandUpForScience! Many reasons motivating this movement, but yesterday as I was reviewing undergrads applications for summer internships, I was reminded of how important this is for the next generation of scientists.

Very cool study by my colleague @tomo.science and collaborators showing the power of crypto-electron tomography for providing insight into the spatial organization of cytoplasmic ribosomes at the surface of mitochondria. Keep on eye out for more awesome work from his lab!
