In this study, we performed small RNA library sequencing using human placental tissues to identify placenta-specific miRNAs. We also tested the hypothesis that human chorionic villi could secrete miRNAs extracellularly via exosomes, which in turn enter into maternal circulation. By

To facilitate selective drug delivery to hepsin (Hpn)-expressing cancer cells, the RIPL peptide (IPLVVPLRRRRRRRRC; 16mer; 2.1 kDa) was synthesized as a novel cell penetrating/homing peptide (CPHP) and conjugated to a liposomal carrier. RIPL peptide-conjugated liposomes (RIPL-Lipo) were prepared by conjugating
