Nanoparticles carrying the C9h peptide to induce apoptosis in cancer cells

Ramón Martínez Mañez, Scientific Director of NANBIOSIS Unit 26 NMR: Biomedical Applications II  toguether with other Scientists from CIBER-BBN, the Institute of Biomedicine of Valencia-CSIC  and  University and Polytechnic University of Valencia, have developed, on a laboratory scale, a new system to cause the apoptosis in cancer cells.

Is consists on nanocapsules carrying a peptide – a small chain of amino acids – that would be released in a controlled manner to generate the apoptosis of the affected cells. “So far, we have worked with cellular models and the results obtained are promising,” says Ramón Martínez Máñez, director of the Interuniversity Institute for Molecular Recognition and Technological Development of the UPV and scientific director of the CIBER-BBN.

The main novelty of the work developed by the researchers  is the encapsulation of the peptide. According to Martínez Máñez, the current problem of the use of these molecules in clinical therapies is their high rate of degradation and low bioavailability. In fact, a large number of peptide therapeutic products do not obtain approval by regulatory agencies due to these limitations.

“Blood plasma hosts more than 120 proteins, among which are numerous enzymes that degrade molecules. The encapsulation of peptides in mesoporous silica particles could be of general application to be administered in a controlled and effective way in clinical practice. In this case, when the nanoparticle enters the cells, the polylysine that covers the nanoparticles degrades and allows the peptide to be released and then induces the death of the cancer cell, “explains Jerónimo Bravo researcher at the IBV.

The use of the Institute of Biomedicine of Valencia-CSIC  would also reduce the toxicity of the therapy, since they are less aggressive than the cytotoxics currently used to induce apoptosis of cancer cells. “In addition, the encapsulation allows to use less medication and would also reduce the side effects in patients,” says Jerónimo Bravo.

After its validation at laboratory scale, the next step would be the evaluation with animal models.

The work of the researchers from the Universitat Politècnica de València, the Institute of Biomedicine of Valencia-CSIC and the CIBER-BBN has been published in the latest issue of Chemistry-A European Journal.

A new polymeric nomedicin facilitates simultaneous pharmacological and gene silencing therapies

Simó Shwartz, Scientific Director of NANBIOSIS U20 In vivo Experimental Platform, has recently published an interesting article “Efficient EFGR mediated siRNA delivery to breast cancer cells by Cetuximab functionalized Pluronic® F127/Gelatin” issued by  Chemical Engineering Journal. The research group of Dr Schwartz has managed to create a micelle formed by a combination of polymers and gelatin that allows to transport effectively large quantities of both nucleic acids and drugs inside. The system also leads to the periphery a series of carboxylic groups that allow anchoring in a very easy way any type of directing molecule such as for example a peptide or antibody.

Numerical models applied to the cornea to improve eye surgery

Researchers of the NANBIOSIS U13 apply numerical models to the cornea to better understand how it behaves and help in surgical planning. Data and algorithms developed through the computer, together with the 3D image, make it easier for ophthalmologists to perform eye surgery more precise and personalized treatments for each patient

The work carried out by Miguel Ángel Ariza Gracia at the Aragón Engineering Research Institute (I3A) has been recognized by the University of Zaragoza with the Extraordinary Award for the Best Doctoral Thesis of the Biomedical Engineering Program in 2017

In this line of research, framed in the European project PopCorn has been working Miguel Angel Ariza since September 2013 under the supervision of Begoña Calvo and José Félix Rodríguez Matas, the research group in Applied Mechanics and Bioengineering (AMB) of the I3A – CIBER -BBN, which coordinates the unit 13 of NANBIOSIS and the Laboratory of Biological Structure Mechanics (LabS) of the Politecnico di Milano, respectively. The Mechanical Characterization of Biological Tissues that the project needs is carried out in NANBIOSIS U13 Tissue & Scaffold Characterization UnitUnit 27 High Performance Computing of NANBIOSIS is also used in this project for the Computational Simulation of Biological Tissues.

The advances in corneal biomechanics open new ways and possibilities to create technical equipment that allow to know the mechanical properties and characteristics of the eye

Here are joined three technologies, the topography (allows to measure the geometry of the cornea), the tonometry of no contact or breath of air (deforms the cornea to obtain dynamic variables that are believed associated with the properties of the cornea) and the models in silico or numerical. The three, together with the phenoptic image technology, “can make it possible to obtain the geometry of a patient’s eye, with its personalized properties to give better advice to doctors in refractive surgeries or in the planning of another surgical intervention,” explains Miguel Angel Ariza

Begoña Calvo, who also works on the numerical modeling of other structures such as skeletal muscle, points out that this “generic” process of reconstruction, transfer of clinical data to the model and generation of a finite element model can be used to simulate other treatments or reproduce different surgical techniques. “The work of Miguel Ángel has allowed us to delve into what is now known as artificial intelligence, having the necessary algorithms to generate databases that can be used in the clinic,” he says.

Fibers of collagen in the cornea

The quality of the cornea tissue depends on the collagen fibers that we have embedded in the corneal stroma, its orientation is what gives that transparency and its links (crosslinks) structural integrity. “Our proposal is to go a step further, to work to better understand collagen fiber,” explains Ariza.

Nowadays, “there is no technical team that provides all the properties and allows to know what quality the corneal tissue has to be able to adequately respond to surgery and subsequent treatments,” recalls Dr. Calvo.
