With the aim of broadening the versatility of lentiviral vectors as a tool in nucleic acid research, we expanded the genetic code in the propagation of lentiviral vectors for site-specific incorporation of chemical moieties with unique properties. Through systematic exploration of the structure-function relationship of lentiviral VSVg envelope by(More)
Strategies to regulate gene function frequently use small interfering RNAs (siRNAs) that can be made from their shRNA precursors via Dicer. However, when the duplex components of these siRNA effectors are expressed from their respective coding genes, the RNA interference (RNAi) activity is much reduced. Here, we explored the mechanisms of action of shRNA(More)
RGD tripeptide is a specific, high-affinity ligand for integrin, which is highly expressed in cancer cells. We previously reported that cRGD chemically modified AAV2 (AAV2(N587+1/azido+RGD)) showed significantly enhanced infectivity compared to RGD genetically inserted AAV2 (AAV2(N587+RGD)) (10.1016/j.biomaterials.2015.11.066) [1]. Herein we provide the(More)
Although EGFR-targeted therapy has been beneficial to colorectal cancer patients, several studies have showed this clinical benefit was restricted to patients with wild-type KRAS exon 2 colorectal cancer. Therefore, it is crucial to explore efficient treatment strategies in patients with KRAS mutations. c-Met is an emerging target for the development of(More)
