As someone working in a field very closely associated with some of the ideas presented in Franken Fran, I will say that this chapter was a bit odd in how specific drugs/molecules were named. Usually the author is either actually surprisingly accurate at getting at the general gist of things or the author knows enough to simply make up a fake drug or disease, but I suspect there may have been a typo/mistranslation with some of the things in the chapter (like somatostatin) because somatostatin actually an inhibitor of growth hormone (which you may have heard of as a performance-enhancing drug). Growth hormone is currently being tested in some anti-aging cocktails, actually, though the jury is still out on whether it works.
This chapter was a bit predictable and cannibalism seems to be becoming a bit too common (speaking as someone who usually finds that kind of stuff entertaining), and the anti-aging cop-out felt cheap, as someone working in anti-aging research, but I did like the reference at the end to the painting of Saturn Devouring His Son. It's still awesome to see that Franken Fran has been revived though, it was one of the things I read in my teenage years that inspired me to go into biology and biotech and the fact that it literally came back to life feels extremely appropriate for Frankenstein Fran.
