How to use

In Vitro:

Bax inhibitor peptide V5 (BIP-V5; 0-50 μM) reduces cell death in STF-cMyc cells but not in SW620 or NCI-H23 cells. BIPV5 does not result in any significant effect on cell cycle arrest at the G2/M phase. V5 treatment upregulates expression of anti-apoptotic proteins Bcl-2 and XIAP by more than 3- and 11-fold and downregulates expression of apoptosis-inducing proteins Bax, Bad, and nuclear factor-κB-p65 by 10, 30, and nearly 50%, respectively.

In Vivo:

Bax inhibitor peptide V5 (BIP-V5; 100 μM) significantly improves islet function following isolation and improves islet graft function following transplantation in mice model.
