  • PCR-free and chemistry-based technology for miR-21 rapid detection directly from tumour cells TALANTA Delgado-Gonzalez, A., Robles-Remacho, A., Marin-Romero, A., Detassis, S., Lopez-Longarela, B., Javier Lopez-Delgado, F., de Miguel-Perez, D., Guardia-Monteagudo, J. J., Antonio Fara, M., Tabraue-Chavez, M., Pernagallo, S., Sanchez-Martin, R. M., Diaz-Mochon, J. J. 2019; 200: 51?56

    Abstract

    miRNAs are well known for being implicated in a myriad of biological situations, including those related to serious diseases. Amongst miRNAs, miRNA-21 has the spotlight as it is reported to be up-regulated in multiple severe pathological conditions, being its quantification a key point in medicine. To date, most of the techniques for miRNA quantification have shown to be less effective than expected; thus, we herein present a novel, rapid, cost-effective, robust and PCR-free approach, based on dynamic chemistry, for the identification and quantification of miRNA directly from tumour cells using both FACS and a fluorescent microplate. This dynamic chemistry novel application involves bead based reagents and allows quantifying the number of miR-21 molecules presented in MDA-MB-468 and H1975 tumour cells.

  • Drug "Clicking" on Cell-Penetrating Fluorescent Nanoparticles for In Cellulo Chemical Proteomics BIOCONJUGATE CHEMISTRY Valero, T., Delgado-Gonzalez, A., Diego Unciti-Broceta, J., Cano-Cortes, V., Perez-Lopez, A. M., Unciti-Broceta, A., Sanchez Martin, R. M. 2018; 29 (9): 3154?60

    Abstract

    Chemical proteomics approaches are widely used to identify molecular targets of existing or novel drugs. This manuscript describes the development of a straightforward approach to conjugate azide-labeled drugs via click chemistry to alkyne-tagged cell-penetrating fluorescent nanoparticles as a novel tool to study target engagement and/or identification inside living cells. A modification of the Baeyer test for alkynes allows monitoring the Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction, guaranteeing the presence of the drug on the solid support. As a proof of concept, the conjugation of the promiscuous kinase inhibitor dasatinib to Cy5-labeled nanoparticles is presented. Dasatinib-decorated fluorescent nanoparticles efficiently inhibited its protein target SRC in vitro, entered cancer cells, and colocalized with SRC in cellulo.

  • Metallofluorescent Nanoparticles for Multimodal Applications ACS OMEGA Delgado-Gonzalez, A., Garcia-Fernandez, E., Valero, T., Cano-Cortes, M., Ruedas-Rama, M. J., Unciti-Broceta, A., Sanchez-Martin, R. M., Diaz-Mochon, J. J., Orte, A. 2018; 3 (1): 144?53

    Abstract

    Herein, we describe the synthesis and application of cross-linked polystyrene-based dual-function nano- and microparticles containing both fluorescent tags and metals. Despite containing a single dye, these particles exhibit a characteristic dual-band fluorescence emission. Moreover, these particles can be combined with different metal ions to obtain hybrid metallofluorescent particles. We demonstrate that these particles are easily nanofected into living cells, allowing them to be used for effective fingerprinting in multimodal fluorescence-based and mass spectrometry-based flow cytometry experiments. Likewise, the in situ reductions of the metal ions enable other potential uses of the particles as heterogeneous catalysts.
