Edelfosine nanoemulsions inhibit tumor growth of triple negative breast cancer in zebrafish xenograft model.

Triple negative breast cancer (TNBC) is known for being very aggressive, heterogeneous and highly metastatic. The standard of care treatment is still chemotherapy, with adjacent toxicity and low efficacy, highlighting the need for alternative and more effective therapeutic strategies. Edelfosine, an alkyl-lysophospholipid, has proved to be a promising therapy for several cancer types, upon delivery in lipid nanoparticles.

The size and composition of polymeric nanocapsules dictate their interaction with macrophages and biodistribution in zebrafish.

Macrophages are pivotal cells of the innate immune system specialized in the phagocytosis of foreign elements. Nanoparticles intentionally designed to target macrophages and modulate their response are of especial interest in the case of chronic inflammatory diseases, cancer and for vaccine development. This work aimed to understand the role of size and shell composition of polymeric nanocapsules (NCs) in their interaction with macrophages, both in vitro and in vivo.

toxicity assays in zebrafish embryos: a pre-requisite for xenograft preclinical studies.

The human cancer cell xenograft in zebrafish embryos has become a very useful preclinical tool in oncology research. While many anticancer drugs have been assayed with this model, few studies regarding the toxicity limits of these drugs for the host have been addressed. Here, we evaluated the acute toxicity of five approved and routinely used human anticancer drugs embracing different mechanism action types: Carboplatin (CarboPt), Irinotecan (IT), Doxorubicin (DOX), Paclitaxel (PT) and Chloroquine (CQ).

The Potential of Zebrafish as a Model Organism for Improving the Translation of Genetic Anticancer Nanomedicines.

In the last few decades, the field of nanomedicine applied to cancer has revolutionized cancer treatment: several nanoformulations have already reached the market and are routinely being used in the clinical practice. In the case of genetic nanomedicines, i.e.

"A Zebra in the Water": Inspiring Science in Spain.

The zebrafish model can play a role in education because of its suitability for manipulation and attractiveness to students compared to traditional lecture-based instruction. Furthermore, zebrafish offer advantages over other model species. Seeing as fewer and fewer students are entering science degree programs, this project has been developed to encourage scientific vocations among secondary school students.
