How to use

In Vitro:

RIN1 inhibits the proliferation of hematologic cancer cell lines and promoted skeletal muscle diferentiation from C2C12 myoblasts. RIN1 (0.6 µM, corresponding to 3 × IC50) decreases the number of MHC+ cells and increased the number of nuclei per cell, indicating that it induces the formation of multinucleated myofbers.
