"I think the question we should be asking is, do you believe in this thing or not?" We discuss the value of MRI-informed muscle biopsies compared with uninformed biopsies, how we go about interpreting FSHD clinical trial gene expression data, and after the song, we show the Jones Lab CRISPRi presentation from the ASGCT annual meeting in Boston.

"I'm not bad. I'm just drawn that way." Today we finish up some questions on clinical trials, therapeutics, what may be in the future, and other random FSHD topics. Good times :)

"Blue Horseshoe loves Anacott Steel." Today we cover recent clinical trial news in the FSHD space and delve a bit deeper into some topics from part 1 of our Reddit Q&A. **Updated version**

The lowlight was Roche canceling their trial. The highlight was Sarepta's announcement of preliminary clinical data. Getting siRNAs, ASOs, and viruses into liver is easy because liver is filled with leaky capillaries, however, muscle is poorly vascularized and blood vessels have tight junctions so targeting cell receptors for enhanced transcytosis greatly enhances skeletal muscle delivery. Sarepta's targeting of the alpha v beta 6 integrin is a great advance in delivery of siRNA against DUX4 and, as predicted, shows the best DUX4 knockdown we have seen so far.
