A new treatment that blocks an aging-related protein restored lost cartilage in old mice and helped prevent arthritis after knee injuries. Human cartilage samples showed similar signs of regeneration, raising hopes for a future drug that could repair joints instead of replacing them.
Well, this same drug (working name MF-300) is a PDGH-15 inhibitor and has already been through phase 1 human trials for a separate condition.
Because PDGH-15 also causes age related muscle weakness.
Now, PDGH-15 also plays a role in cancer prevention, and there may be a few other less obvious functions.
I don’t know if the results of the phase 1 trials have been published yet, but it’s been a while since I checked.
I’ve been hearing about MF-300 for a little under a year, and with these same claims about restoring cartilage.
