Sorafenib induces ferroptosis in human cancer cell lines originating from different solid tumors
The four amino-acid substitutions relative to native GHRH(1-29) are engineered to resist that enzymatic degradation particularly cleavage by dipeptidyl peptidase-4 (DPP-4) at the N-terminus which extends the peptides functional plasma half-life modestly relative to unmodified sermorelin-type fragments
