    6. Implantable Chemotherapy-Loaded Silk Protein Materials for Neuroblastoma Treatment.

      "Furthermore, intra-tumor delivery decreased the maximum plasma concentration compared to IV delivery, reducing systemic exposure and possibly reduing long-term side effects of chemotherapy exposure. Histopathologically, tumors with remission periods >25 days before recurrence transformed from a "small-round-blue cell" (SBRC) to predominantly "large cell" neuroblastoma (LCN) histopathology, a more aggressive tumor subtype with unfavorable clinical outcomes. These results show that intratumoral chemotherapy delivery may be a treatment strategy for pediatric neuroblastoma, potentially translatable to other focal tumors types. Furthermore, this treatment modality allows for a clinically relevant mouse model of tumor transformation that may be used for studying the phenotypical tumor ...

    13. Neuroblastoma-targeted nanocarriers improve drug delivery and penetration, delay tumor growth and abrogate metastatic diffusion.

      "In animal models obtained by the orthotopic implant of either MYCN-amplified or MYCN single copy human neuroblastoma cell lines, treatment with HSYWLRS-targeted, doxorubicin-loaded Stealth Liposomes increased tumor vascular permeability and perfusion, enhancing tumor penetration of the drug. This formulation proved to exert a potent antitumor efficacy, as evaluated by bioluminescence imaging and micro-PET, leading to (i) delay of tumor growth paralleled by decreased tumor glucose consumption, and (ii) abrogation of metastatic spreading, accompanied by absence of systemic toxicity and significant increase in the animal life span. Our findings are functional to the design of targeted nanocarriers with potentiated therapeutic efficacy ...

    14. Tumor vascular targeted liposomal-bortezomib minimizes side effects and increases therapeutic activity in human Neuroblastoma.

      Abstract

      Neuroblastoma is a childhood cancer with poor long-term prognosis in advanced stages. A major aim in neuroblastoma therapy is to develop targeted drug delivery systems to ameliorate drug therapeutic index and efficacy. In this study, a novel bortezomib (BTZ) liposomal formulation was set-up and characterized.

    15. Improving the delivery of chemotherapy with graphene

      A new study published in IOP Publishing's journal 2D Materials has proposed using graphene as an alternative coating for catheters to improve the delivery of chemotherapy drugs. The research suggests that placing graphene - an extremely thin sheet of carbon atoms - on the internal surfaces of intravenous catheters commonly used to deliver chemotherapy drugs into a patient's body will improve the efficacy of treatments, and reduce the potential of the catheters breaking.

      Roadblocks to success for RNA CARs in solid tumors.

      "While CAR therapy has begun to demonstrate efficacy, cell-engineering techniques that result in permanent genomic modification carry several safety concerns. CAR expression driven by RNA creates a platform for delivery of highly-active cell therapy while avoiding long-term CAR-driven toxicity. Using models of pediatric neuroblastoma, we have found that RNA CAR T cell activity is limited by ineffective tumor infiltration."

      3-D 'organoids' grown from patient tumors could personalize drug screening

      "In recent years, scientists have developed organoid cell culture systems as an alternative approach to grow normal and diseased tissue in a dish. In contrast to cell lines, organoids display the hallmarks of the original tissue in terms of its 3D architecture, the cell types present, and their self-renewal properties. Given the advantages of organoids, Garnett and Hans Clevers of the Hubrecht Institute set out to test whether these cultures could potentially bridge the gap between cancer genetics and patient outcomes."

      SapC-DOPS nanovesicles induce Smac- and Bax-dependent apoptosis through mitochondrial activation in neuroblastomas.

      "Taken together, our results indicate that SapC-DOPS acts through a mitochondria-mediated pathway accompanied by an early release of Smac and Bax. Specific tumor-targeting capacity and anticancer efficacy of SapC-DOPS supports its potential as a dual imaging and therapeutic agent in neuroblastoma therapy."

    19. Nanoparticles at Specific Temperature Stimulate Antitumor Response

      "Among the many options for cancer treatment pursued by science, immunotherapy is a contemporary focus. The immune system recognizes and usually eliminates small tumors, but other tumors become clinical problems and are known to block the antitumor tendencies with a natural system for immunosuppression. Recently, scientists have worked to learn how to reverse this tumor-mediated immunosuppression. In addition, phagocytes (key actors in immunosuppression and immunostimulation and that quickly take up nanoparticles) have provided options for new strategies. Fierings's studies were done in mice with a melanoma tumor model, and began with inserting iron nanoparticles directly into the tumors while ...
