Abstract Lycorine (Ly) is a promising natural compound with extensive antitumor activities. However, due to poor aqueous solubility and low bioavailability, the research and development of Ly anticancer drugs has been greatly restricted. Recently, the carrier-free nanoparticles have emerged as an outstanding drug delivery system. In this study, we prepared a DSPE-PEG modifying Ly nanoparticle (DS-Ly NPs) to overcome these drawbacks. We find that compared with Ly, DS-Ly NPs can significantly inhibit cell viability. Meanwhile, DS-Ly NPs treatment results in higher promotion of apoptotic and autophagic capacities, as well as inhibition of migration and invasion. Furthermore, DS-Ly NPs exhibits a better antitumor effect in AOM/DSS induced colorectal tumors and orthotopic hepatocellular tumors than Ly in repression of multiple oncogenic processes, which may benefit from the advantages of carrier-free nanoparticle. Beside, we showed that DS-Ly NPs can prolong the blood circulation time better than Ly. Taken together, these results have demonstrated that carrier-free nanoparticle provides a new therapeutic strategy for treating cancer.

To discover and develop novel natural compounds with therapeutic selectivity or that can preferentially kill cancer cells without significant toxicity to normal cells is an important area in cancer chemotherapy. Kushen, the dried roots ofSophora flavescensAiton, has a long history of use in traditional Chinese medicine to treat inflammatory diseases and cancer. Kushen alkaloids (KS-As) and kushen flavonoids (KS-Fs) are well-characterized components in kushen. KS-As containing oxymatrine, matrine, and total alkaloids have been developed in China as anticancer drugs. More potent antitumor activities were identified in KS-Fs than in KS-Asin vitroandin vivo. KS-Fs may be developed as novel antitumor agents.

SummaryThe plasminogen activation system is thought to be important in cell migration processes. A role for this system during smooth muscle cell migration after vascular injury has been suggested from several animal studies. However, not much is known about its involvement in human vascular remodelling. We studied the involvement of the plasminogen activation system in human smooth muscle cell migration in more detail using an in vitro wound assay and a matrix invasion assay. Inhibition of plasmin activity or inhibition of urokinase-type plasminogen activator (u-PA) activity resulted in approximately 40% reduction of migration after 24 h in the wound assay and an even stronger reduction (70-80%) in the matrix invasion assay. Migration of smooth muscle cells in the presence of inhibitory antibodies against tissue-type plasminogen activator (t-PA) was not significantly reduced after 24 h, but after 48 h a 30% reduction of migration was observed, whereas in the matrix invasion assay a 50% reduction in invasion was observed already after 24 h. Prevention of the interaction of u-PA with cell surface receptors by addition of soluble u-PA receptor or α2-macroglobulin receptor associated protein (RAP) to the culture medium, resulted in a similar inhibition of migration and invasion. From these results it can be concluded that both u-PA and t-PA mediated plasminogen activation can contribute to in vitro human smooth muscle cell migration and invasion. Furthermore, the interaction between u-PA and its cell surface receptor appears also to be involved in this migration and invasion process. The inhibitory effects on migration and invasion by the addition of RAP suggests an involvement of a RAP sensitive receptor of the LDL receptor family, possibly the LDL-receptor related protein (LRP) and/or the VLDL receptor.
