Peter K Todd MD/PhD Lab @Umich. We study how short tandem repeats impact neuronal function and human disease. Ataxia, ALS/FTD, Fragile X/FXTAS, CANVAS.

It took a near-collapse of our research infrastructure and a constitutional crisis to make it happen, but we are moving our former Twitter activities to Bluesky. Looking forward to a happier scientific discussion in this new space: https://t.co/M3sVRgb7Iu

If the PNAS version of the article is behind a paywall for you, the preprint is here:

Intronic GGGGCC hexanucleotide repeat expansions in C9orf72 are the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Despite its intronic location,...

Knowing the template for DPR production from RAN translation in C9orf72 FTD and ALS is a key first step to developing effective therapies for these currently untreatable conditions. 4/5

In contrast, we find no evidence for lariat RNAs or intron retention as endogenous templates for RAN translation, as both species are very rare and inefficient translation templates in neurons. 3/5

We used nanopore coupled to 5'RACE to find the 5' end of repeat containing RNAs. 95%+ of repeat RNAs initiate in the intron rather than at annotated start sites. These short (~80nt) 5' leader mRNAs are capped and polyadenylated and robustly translated in reporter assays. 2/5

Ever wonder how intronic repeats in C9orf72 get translated into toxic proteins in ALS? We found that transcription initiates within the intron to generate novel endogenous mRNA templates for RAN translation in patient neurons and mouse models. 1/5

Bummed I missed it this year!
Happy AUG1 RNA Day! We celebrated it by many great discussions at the Gordon conference on #ALS in the beautiful Portland ME. Many thanks to @LuVaDeBo Christine Vande Velde @BarmadaLab Magda Polymenidou for organizing it! @FrattaLab @RueppLab @smslmoon

You deserve better. We all do.
Harvard notified me today that this K99 grant is terminated.

Half of children died. A thread. 🧵
@DavidWolfe How did humans survive for the last 100,000's years without vaccines and modern hygiene? It's either a bloody miracle or the human bodys' immune system is perfectly fine and naturally effective.

Thank you NIH funded basic science

NEW: The Trump administration is exploiting a loophole to keep funding frozen at the NIH - a move that some legal experts say is illegal. Federal Register notices are blocked so no grant-review sessions can be scheduled. All the gritty details in @Nature

Last night my brilliant friend with 20 years of expertise in Neuroscience including a decade at NIDA was fired because she was recently promoted for her outstanding performance and it triggered the probation period. This is not making NIH more efficient, this is not making us
