#apaperaday Today's pick is by Kumai et al on an individual who turned out to have Becker muscular dystrophy but who was diagnosed because he developed rhabdomyolysis due to anesthesia. Published in Internal Medicine. Very nice example of a good case report! DOI: 10.2169/internalmedicine.5972-25

#apaperaday Please note that next week it will be #afewpaperaweek because of a busy schedule with the @euronmd.bsky.social TREAT-NMD translational training school happening in Leiden. Yours truly will be teaching, chairing sessions and leading working groups.

#apaperaday Unexpectedly working from home, so an older pick from the 'from home' pile by Young Jeon et al on EZH2 inhibition in Duchenne models published in Science Advances. NB: the title hides that the authors also so single cell sequencing and spatial transcriptomics DOI: 10.1126/sciadv.adr4443

#apaperaday Today one of my favorite types of papers, i.e. a strange pathogenic variant in the dystrophin gene, where one would expect Duchenne, but sees Becker and there is a genetic explanation, by Naruse et al in Annals Neurology DOI: 10.1002/ana.78096

#apaperaday Today's pick is by Martinez-Pizarro et al published in @narjournal.bsky.social Molecular Medicine, using antisense oligonucleotides (ASO) to increase inclusion of a microexon in the CPEB4 gene.

#apaperaday Today's pick is from @natcomms.nature.com by Esper et al on the consequences of lack of dystrophin during mouse embryogenic muscle formation. Yuzu was not interested in the paper and preferred playing. DOI: 10.1038/s41467-025-64999-3

#apaperaday Today a case report by Gutierrez-Baena et al in Internal and emergency medicine, on a Duchenne patient with euglycemic ketoacidosis due to dapaglifozin (a medicine that prevents glucose reabsorption by the kidney, a treatment for diabetes & heart failure). DOI: 10.1007/s11739-025-04058-3

#apaperaday Today's pick is a commentary by Ahrens-Nicklas and Musunuru in @ajhgnews.bsky.social to the plausible mechanism publication in NEJM featured recently. The authors were involved in the individualized base editing therapy development (earlier #apaperaday). DOI: 10.1016/j.ajhg.2025.10.006

#apaperaday Hot from the press, the @natcomms.nature.com paper by Mathews et al on the relationship between Htt expression and somatic instability in Huntington's disease mouse models. Partly presented already at conferences, but now the full story. DOI: 10.1038/s41467-025-64936-4

#apaperaday Today's pick is from @narjournal.bsky.social by Stratton et al on testing antisense oligonucleotides (ASOs) for exon 5 skipping in a pig model for CLN3 Batten disease. Obviously my office pigs had to feature. DOI: 10.1093/nar/gkaf1141

#apaperaday Today & tomorrow there will be a DMD themed series to commemorate the Action Duchenne conference that takes place. The glass house is with me, but also got acquainted with some of my office pets. Today's pick is on caregiver perception of Elevidys effects. doi: 10.1007/s40120-025-00842-7

#apaperaday Today's pick is hot off the press: the @nejm.org sounding board paper from @fda.gov Prasad et al on the plausible mechanism pathway for individualized base/gene editing treatments for eligible patients. DOI: 10.1056/NEJMsb2512695

#apaperaday Today's pick is by Vorontsova et al published in @mdpiopenaccess.bsky.social International Journal of Molecular Sciences, a case report of 3 females with Duchenne muscular dystrophy due to translocations involving the dystrophin gene. DOI: 10.3390/ijms26199389

Instead of Klaus the coming weeks I'll be traveling with a mini-glass house to raise awareness for muscle diseases and the special "Glazen Huis" action in December to raise money for children affected by muscle diseases www.linkedin.com/posts/annemi...

#apaperaday back home. Reunited with Yuzu who is mainly interested in scratches and not confetti making of today's pick in @pnas.org by Cohen et al on the use of synthetic bottlebrush block copolymers to stabilize muscle fiber membranes in a mouse model of Duchenne. Doi 10.1073/pnas.2513599122

The final TACT themed #apaperaday is about microdystrophin gene therapy again but now with a focus on the immune response that is induced after AAV natural infection or gene therapy infusion. A paper from Saha et al published in Human Gene Therapy doi 10.1177/10430342251385586

It is clear that Duchenne muscular dystrophy is more than a muscle disease, and other tissues and cells are affected as well, like the brain, but also the neuromuscular junctions (NMJ). At least in mice, exon skipping can improve deficits in the NMJ. www.sciencedirect.com/science/arti...

#apaperaday Today’s pick featured before as a @biorxivpreprint.bsky.social but now the full paper is out in Skeletal Muscle, by Hildyard et al on dystrophin expression regulation during muscle repair. Showing off the mouse doctor I received yesterday from TACT. doi10.1186/s13395-025-00398-y

#apaperaday again from the TACT meeting in Atlanta, with the WAKZ Glass House on Tour and again about microdystrophin with a pick from Foltz et al from Molecular Therapy methods and clinical development with a head to head comparison of two micro-dystrophins doi 10.1016/j.omtm.2025.101519

#apaperaday with delay due to travels to the TREAT-NMD advisory committee for therapeutics meeting in Atlanta. Also taking the WAKZ (children hospital at LUMC) glass house on tour rather than Klaus to commemorate the glazen huis topic of spieren voor spieren in December (Dutch people understand).

There are many good reasons to attend: the speakers, the topic but also the surrounding and the @keystonesymposia.bsky.social concept. Highly recommended

#apaperaday Today's pick is a commentary by Kerkhof and Buijsen from Molecular Therapy Nucleic Acids, about a paper by Yameogo et al, who describe a new variant for Friedreich's ataxia and show that antisense oligonucleotides correct normal transcripts. DOI: 10.1016/j.omtn.2025.102723

#apaperaday Today Yuzu picked a paper blindly from the pile. Turned out to be from @dmmjournal.bsky.social by Braunreiter et al on the characterization of a humanized dystrophin exon 52 deletion model to facilitate developing of mutation specific therapies. Doi 10.1242/dmm.052182

Our paper on the goals and work of the N=1 collaborative for making individualized antisense oligonucleotide therapies (and others) a reality was published in @narresearch.bsky.social 6 months ago. If you missed it: academic.oup.com/nar/article/...

Due to the TREAT-NMD advisory committee of therapeutics meeting that takes place this weekend in Atlanta, we're shifting the #apaperaday week from Tuesday-Sunday. So not paper for your this Monday and next Monday but extras on Saturday and Sunday. Leaving you with a sunset picture

#apaperaday Today's pick is again from the @erdera.bsky.social general assembly meeting with the Kobe Animal Kingdom Shoebill decorating a pick from @biorxivpreprint.bsky.social by Ling et al on the NMA oligonucleotide modification that was also mentioned at #OTS2025 doi 10.1101/2025.10.06.680653
