Can't believe we just submitted our 6th paper of the year & we're not even done yet. Working on several more we hope to submit soon! And just submitted the proofs for another the 2nd paper. Hope our banner paper year translates into some successful funding apps.

Last week I had the immense honour to take part in the 2026 VCP international Scientific & Community Summit in Atlanta organized by Cure VCP Disease. I felt like when we have the first therapies for this disease, we'll know this is where it started. See all I had to say here: tinyurl.com/37m6phxm

Roche's decision to stop development of two huntingtin-lowering programmes is disappointing, but the story doesn't end there. Years of research have answered some key questions, raised many new ones, and will inform the next generation of HD trials. Read about it here: en.hdbuzz.net/looking-back...

I wrote this in a week where it felt like professoring while parenting (and equally, parenting while professoring) was impossible. This feeling ebbs and flows. Seems like Mothers Day is as good a time as any to share, maybe it will help someone else feel less alone. The More Paradox 1/8

What a weird job somedays. We've published multiple high impact papers recently & are on track for 6-8 papers this year, including new therapeutic strategies in HD & ALS. And yet, all I can think about is how our work isn't worth even discussing at CIHR...

Skyhawk Therapeutics have received the regulatory approval needed to broaden its FALCON-HD trial to include the United States, Canada, and the UK. The expanded trial will enroll up to 400 more people with Stage 2 and early Stage 3 HD across more than 40 sites worldwide.

** if you hold #CIHR funding, you will be required to participate in peer review. …we are reinforcing a clear expectation: Conditions of Funding for Project Grants and other funding opportunities now specify that NPAs who are successful are expected to participate in peer review when invited.

A Chemical Proteomics Method to Quantify Cysteine S-Acylation

S-acylation, often referred to as S-palmitoylation, is a reversible and dynamic posttranslational modification that corresponds to the addition of a long-chain fatty acid to cysteine (Cys) residues. Established mass spectrometry-based chemoproteomics methods have improved our understanding of the S-acylation proteome, notably by identifying hundreds of S-acylated proteins, sometimes with the modified Cys. However, the precise quantification of S-acylation levels for each Cys within a single sample remains challenging at the proteome level. Quantification of S-acylation levels is critical to further our understanding of protein S-acylation in cellular function and its role in health and diseases. We report here the development of an S-acylation quantification workflow based on the sequential labeling of free Cys and S-acylated Cys with isotopic labeling reagents. The workflow was extensively optimized, notably by comparing the number of sites identified with two alkyne-tagged Cys-reactive isotopic probes and four azido-tagged biotin-based capture reagents. By integrating this enhanced workflow with high-field asymmetric waveform ion mobility spectrometry (FAIMS) on LC–MS/MS instruments for the separation of labeled peptides, over 17,000 unique Cys could be quantified in biological samples. Application of the S-acylation quantification workflow to cellular proteomes allowed for the quantification of S-acylation levels in a HeLa proteome. We also identified dynamic S-acylation changes in response to autophagy induction.
