Abstract 10P
Interleukin-24 (IL-24) is known to selectively induce apoptosis in cancer cells through endoplasmic reticulum (ER) stress when it is expressed inside the cells. However, IL-24 alone is unable to enter the cells and consequently unable to inhibit cell proliferation. In the present study, we developed a novel chimeric protein, P28-IL-24, containing IL-24 which is linked to P-28, a defined cancer specific cell penetrating peptide and a P53 stabilizer, to target IL-24 into breast cancer cells. Afterwards, specific and non-specific cytolethal effect of this fusion protein were evaluated in vitro and in vivo.
