Abstract
We aimed to develop an anti-angiogenic model for breast cancer by combining (1) siRNA-based therapy delivered by self-complementary adeno-associated virus serotype 2 (scAAV2) vectors to target tumor vasculature, and (2) noninvasive monitoring to tumor response to anti-angiogenesis by photoacoustic (PA) imaging. scAAV2 vector containing 7 surface exposed tyrosine to phenylanine capsid mutations was able to transduce microvascular endothelial cells with high efficiency. siRNAs against UPR (unfolded protein response)-IRE1α, XBP-1, ATF6 significantly inhibited breast cancer-induced angiogenesis in vitro by inhibiting endothelial cell survival. PA imaging showed that knockdown of UPR proteins greatly reduced tumor angiogenesis in vivo in breast cancer models.
