Molecules, Vol. 27, Pages 4377: Tetrazine-Induced Bioorthogonal Activation of Vitamin E-Modified siRNA for Gene Silencing
Xinjing Tang The temporal activation of siRNA provides a valuable strategy for the regulation of siRNA activity and conditional gene silencing. The bioorthogonal bond-cleavage reaction of benzonorbonadiene and tetrazine is a promising trigger in siRNA temporal activation. Here, we developed a new method for the bio-orthogonal chemical activation of siRNA based on the tetrazine-induced bond-cleavage reaction. Small-molecule activatable caged siRNAs were developed with the 5′-vitamin E-benzonobonadiene-modified antisense strand targeting the green fluorescent protein (GFP) gene and the mitotic kinesin-5 ...

Myeloid Derived Suppressor Cells Interactions With Natural Killer Cells and Pro-angiogenic Activities: Roles in Tumor Progression
Conclusions MDSC are major players in the immunosuppressive scenario in cancer, thanks to their phenotype heterogeneity and critical interaction with several innate immune cells, thus representing a crucial target in oncology. Here we reviewed the interactions of MDSCs with NK cells. The contribution of key cytokines, chemokines and mediators active in this process have been discussed. We also described the contribution of MDSC on angiogenesis directly or indirectly through interactions with NK and immunosuppressive activities. A parallel of the cancer associated to the decidual counterpart of these cells is discussed, a...

Advances in nanomicelles for sustained drug delivery
Publication date: 25 November 2017 Source:Journal of Industrial and Engineering Chemistry, Volume 55 Author(s): Najmeh Amirmahani, Nosrat O. Mahmoodi, Mohsen Mohammadi Galangash, Atefeh Ghavidast The efficient direct access of therapeutic molecules to the target tissues is still a major obstacle in developing useful therapeutic interventions. Over the past decades, polymeric micelles are interesting nanocarries for drug delivery systems due to small size (10–100nm), low toxicity, capacity to solubilize lipophilic drugs in core and high drug loading. Here, the design of various nanomicelles such as amphiphilic dendrimer,...

Akt/AMPK/mTOR pathway was involved in the autophagy induced by vitamin E succinate in human gastric cancer SGC-7901 cells.
Abstract Vitamin E succinate (VES), a derivative of vitamin E, is a promising cancer chemopreventive agent that inhibits tumor promotion by inducing apoptotic cell death. The effects of VES on autophagy, an intricate programmed process which helps cells survive in some stressed situations by degrading some cytoplasmic material, are unclear. When human gastric cancer cells SCG-7901 were exposed to VES, both the level of microtubule-associated protein 1 light chain 3 and the yeast ATG6 homolog Beclin-1 increased, and related autophagy genes were activated, thereby suggesting that autophagy was induced by VES. We als...
