NT-09 * CO-DELIVERY OF siRNA AND CHEMOTHERAPY; A NEW APPROACH FOR GBM TREATMENT USING A NANOCARRIERS SYSTEM
Over the past decade, progress in genomics and proteomics has paved the way for identifying promising macromolecular therapeutics including small RNAs, peptides and proteins. Still, the vast majority of leading drugs candidates for the treatment of CNS diseases is ineffective, mainly due to restricted passages across the BBB. Nanoparticles packaging of therapy is of particular interest for its potential to treat brain tumors, due to their ability to transport drugs through the BBB, while improving the performance of drugs by decreasing systemic and local toxicity. We chose GBM known for its poor prognosis, as a model for b...

Novel siRNA delivery strategy: a new "strand" in CNS translational medicine?
Abstract RNA interference has been envisaged as a powerful tool for molecular and clinical investigation with a great potential for clinical applications. In recent years, increased understanding of cancer biology and stem cell biology has dramatically accelerated the development of technology for cell and gene therapy in these areas. This paper is a review of the most recent report of innovative use of siRNA to benefit several central nervous system diseases. Furthermore, a description is made of innovative strategies of delivery into the brain by means of viral and non-viral vectors with high potential for trans...

Autophagy Is a Defense Mechanism Inhibiting Invasion and Inflammation During High-Virulent Haemophilus parasuis Infection in PK-15 Cells
In this study, we sought to investigate whether SH0165 (serovar 5, high-virulent strain) and HN0001 (serovar 6, non-virulent strain) infection induces autophagy and the specific role of autophagy in bacterial invasion and inflammation during H. parasuis infection. Moreover, we explored the mechanism underlying autophagy regulated inflammation through inflammatory signaling cascades during H. parasuis infection. This observation could provide useful information for further understanding the role of autophagy in H. parasuis infection and improve our knowledge of new strategies against this pathogen. Materials and Methods B...

WNK1-OSR1 kinase-mediated phospho-activation of Na+-K+-2Cl- cotransporter facilitates glioma migration
Conclusion: Together, our data show a novel role for the WNK1/OSR1/NKCC1 pathway in basal and TMZ-induced glioma migration, and suggest that glioma treatment with TMZ might be improved by drugs that inhibit elements of the WNK1/OSR1/NKCC1 signaling pathway.

Abstract 2312: Identifying novel cancer stem cell target for triple-negative breast cancer
The objective of this study was to investigate the role of HN1L in regulating BCSC and metastasis in TNBC, and to determine the mechanism of action of HN1L in BCSC. Knocking down HN1L by shRNA in SUM159 and MDAMB231 cell lines significantly decreased mammosphere forming efficiency (MSFE) and CD44+/CD24low/- population. To assess the contribution of HN1L to BCSC and tumor growth, a patient derived human-cancer-in-mouse xenograft model and two cancer cell line xenograft models were employed. To ensure targeted delivery, siRNA was packaged into DOPC liposomes and delivered into mice via intraperitoneal injection. Results show...

Overcoming resistance to sonic hedgehog inhibition by targeting p90 ribosomal S6 kinase in pediatric medulloblastoma
ConclusionsRSK inhibitors are promising because they target RSK which is correlated with SHH patients as well as cause high levels of apoptosis to only MB cells. Importantly, BI‐D1870 crosses the BBB, acting as a scaffold for development of more long‐lived RSK inhibitors. Pediatr Blood Cancer © 2013 Wiley Periodicals, Inc.

Abstract LB-207: mTORC2/Akt signaling is modulated by noncanonical mitochondrial Notch1/PINK1 interaction in myc-amplified medulloblastoma tumorigenesis
Medulloblastoma is known to be the most malignant pediatric brain tumor. The armamentarium of targeted therapies to currently treat medulloblastoma and similar pediatric central nervous system malignancies is extremely limited, often necessitating the need to combat such tumors with modified regimens of therapeutic options designed originally to target adult neoplasms. Given such limited therapies, a budding focus on the role of mitochondrial dysregulation in the tumorigenesis of such pathologies merits consideration. Mitochondria are known to play fundamental roles in multiple processes conserved across eukaryotic species...

Cancers, Vol. 11, Pages 406: Alpha6-Integrin Regulates FGFR1 Expression through the ZEB1/YAP1 Transcription Complex in Glioblastoma Stem Cells Resulting in Enhanced Proliferation and Stemness
Catherine SEVA Glioblastoma (GBM) is the most lethal primary brain tumor in adults and is known to be particularly aggressive and resistant to anti-cancer therapies, mainly due to the presence of GBM stem cells (GBMSC). By in vitro approaches supported by analysis from patients’ databases, we determined how α6-integrin and Fibroblast Growth Factor Receptor 1 (FGFR1) work in concert to regulate proliferation and stemness of GBMSC. We showed that α6-integrin regulates the expression of FGFR1 and its target gene Fokhead Box M1 (FOXM1) via the ZEB1/YAP1 transcription complex. Thes...
