  Se trata de un nanofármaco que abre una nueva vía para la prevención de la metástasis en el cáncer colorrectal   El nuevo fármaco funciona como un dron que identifica las células madre metastásicas, administra el fármaco y destruye únicamente estas células bloqueando la metástasis. De esta forma se evita la toxicidad general asociada a los tratamientos habituales, y se abre una nueva vía para prevenir la metástasis en el cáncer colorrectal. leer mas..

Abstract Protein materials are rapidly gaining interest in materials sciences and nanomedicine because of their intrinsic biocompatibility and full biodegradability. The controlled construction of supramolecular entities relies on the controlled oligomerization of individual polypeptides, achievable through different strategies. Because of the potential toxicity of amyloids, those based on alternative molecular organizations are particularly appealing, but the structural bases on nonamylogenic oligomerization remain poorly studied. We have applied spectrofluorimetry and spectropolarimetry to identify the conformational conversion during the oligomerization of His-tagged cationic stretches into regular nanoparticles ranging around 11 nm, useful for tumor-targeted drug delivery. We de...

  Abstract   A versatile evaporation-assisted methodology based on the coffee-drop effect is described to deposit nanoparticles on surfaces, obtaining for the first time patterned gradients of protein nanoparticles (pNPs) by using a simple custom-made device. Fully controllable patterns with specific periodicities consisting of stripes with different widths and distinct nanoparticle concentration as well as gradients can be produced over large areas (∼10 cm2) in a fast (up to 10 mm2/min), reproducible, and cost-effective manner using an operational protocol optimized by an evolutionary algorithm. The developed method opens the possibility to decorate surfaces “a-la-carte” with pNPs enabling different categories of high-throughput studies on cell motility.   https://pubs.acs.o

  Precise execution of recombination during meiosis is essential for forming chromosomally-balanced gametes. Meiotic recombination initiates with the formation and resection of DNA double-strand breaks (DSBs). Cellular responses to meiotic DSBs are critical for efficient repair and quality control, but molecular features of these remain poorly understood, particularly in mammals. Here we report that the DNA damage response protein kinase ATR is crucial for meiotic recombination and completion of meiotic prophase in mice. Using a hypomorphic Atr mutation and pharmacological inhibition of ATR in vivo and in cultured spermatocytes, we show that ATR, through its effector kinase CHK1, promotes efficient RAD51 and DMC1 assembly at RPA-coated resected DSB sites and establishment of interh...
