Abstract B57: RNAi Nanotechnology for Cancer Target Validation and Therapy
RNA interference (RNAi) represents a promising strategy for identification and validation of putative therapeutic targets, and for treatment of a myriad of important human diseases including cancer. The ubiquitous application of RNAi in cancer research and therapy is nevertheless hindered by the challenge of effective systemic in vivo delivery of RNAi agents (e.g., siRNA) to solid tumors, which requires overcoming of multiple physiological barriers, such as enzymatic degradation, rapid elimination by renal excretion or by the mononuclear phagocyte system (MPS), poor tumor penetration, and insufficient cellular uptake and e...

Abstract C171: Human anti-Nucleolin recombinant immunoagents as new potential tools for melanoma treatment
Immunotherapy and immune-based anti-cancer molecules represent a valid strategy to fight cancer. However, the choice of tumor-specific surface molecules for the selective targeting of cancer cells still represents a critical step in the study design for the development of new therapeutic approaches. Notably, the development of phage-display technology for the selection of fully human single chain antibody fragments (scFvs) and complete antibodies directed toward tumor-associated antigens has represented a significant advancement for immunotherapy.Nucleolin (NCL) is one of the most abundant non-ribosomal proteins in the nuc...

Abstract A83: Lentiviral shRNA-mediated knockdown of eosinophilic Galectin-10/Charcot-Leyden crystals: A novel approach to cancer immunotherapy
Conclusion: The creation of galectin-10 knockdown eosinophils provides a useful model for investigating eosinophilic galectin-10's ability to modulate T cell access and homing to tumors, and a putative role, similar to Treg galectin-10, in regulating tumoral T lymphocytic proliferation can certainly be envisioned. The consideration of galectin-10 knockdown eosinophils as a singular approach to cancer immunotherapy, or in combination with other anti-cancer therapies such as adoptive T cell therapies, or therapeutic cancer vaccines, is intriguing.Note: This abstract was not presented at the conference.Citation Format: Christ...
