Description Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring neuropeptide first isolated from the brain in the 1970s

The study established that FOXO4 maintains senescent cell viability by targeting p53 to the nucleus and preventing apoptosis, and that disrupting the FOXO4-p53 interaction with FOXO4-DRI causes p53 nuclear exclusion and cell-intrinsic apoptosis in ionising radiation-induced and doxorubicin-induced senescent IMR90 fibroblasts

Once FOXO4-DRI is reconstituted, the conversion from a target dose to syringe units depends on the chosen dilution
