Programming DNA to deliver cancer drugs

(University of Delaware) A research team at the University of Delaware has developed technology to program strands of DNA into switches that turn proteins on and off. This technology could lead to the development of new cancer therapies and other drugs.

Louro, Ilídio J. CorreiaAbstractGraphene family nanomaterials’ (GFN) ability to interact with near-infrared light has propelled their application in cancer photothermal therapy. Furthermore, the graphitic lattice of GFN can adsorb different types of molecules, which has motivated their use in cancer drug delivery. However, the direct application of GFN in cancer therapy is severely hindered by their poor colloidal st...

SummaryMicrotubule as an important target in the cancer therapy was used to design novel tubulin polymerization inhibitors. Sulfanilamide-1,2,3-triazole hybrids were designed by a molecular hybridization strategy and their antiproliferative activity against three selected cancer cell lines (BGC-823, MGC-803 and SGC-7901) were evaluated. All sulfanilamide-1,2,3-triazole hybrids displayed potent inhibitory activity against all cell lines. In particular, compound10b showed the most excellent inhibitory effect against MGC-803 cells, with an IC50 value of 0.4 μM. Cellular mechanism studies elucidated that10b induced apoptosi...

There have been significant and continued improvements in the treatment for and survival from childhood cancer over the past few decades. Based on Australian and overseas statistics, the 5 year survival rates have improved to approximately 80% and the majority of these children will go on to become long term survivors (Baade et al., 2010; Gatta et al., 2009; Miller et al., 2016; Ries et al., 2008). Accompanying this increased survival, long-term physical and psychological consequences of cancer therapy are becoming more apparent.

Cardiorenal complications of immune checkpoint inhibitors, Published online: 16 July 2018; doi:10.1038/s41581-018-0035-1Immune checkpoint inhibitors (ICIs) have led to a paradigm shift in cancer therapy; however, these agents can induce immune-related adverse events (irAEs) in off-target organs. This Review describes the mechanism of action of ICI therapies and how these agents induce irAEs in the kidney and heart.
