Peptide‐Capped Mesoporous Nanoparticles: Toward a more Efficient Internalization of Alendronate.

Osteoporosis is an illness which appears when the osteoblast/osteoclast activities are unbalanced taking place bone resorption (caused by osteoclasts) in higher extension than bone formation (induced by osteoblasts). Alendronate is one of the most used drugs for osteoporosis treatment despite its scarce bioavailability. In an attempt to improve it, gated mesoporous silica nanoparticles, for the controlled release of alendronate, have been synthesized and characterized. These hybrid nanoparticles include labelled alendronate inside the porous, those porous are capped with a peptide designed to be selectively cleaved by cathepsin K enzyme (overexpressed in osteoclasts). Two CIBER-BBN units of the ICTS NANBIOSIS wer[...]

New therapy for triple negative breast cancer is successfully tested in preclinical animals

Researchers CIBER-BBN and NANBIOSIS Unit 26, the Príncipe Felipe Research Center (CIPF), the Universitat Politècnica de València (UPV) and the Institut de Recerca Biomèdica (IRB) of Barcelona manage to inhibit tumor growth, reduce metastasis and decrease the toxicity of the antitumor drug Navitoclax in preclinical animal models of triple negative breast cancer (TNBC). These types of TNBC tumors do not express any of the three receptors involved in most breast cancers (estrogen, progesterone, and HER2), so the most common treatments such as hormone therapy are not viable in these patients. This new study, led by Mar Orzáez, principal investigator of[...]

NAV-GAL, a new senolytic drug against cancer, on spanish TV

The work carried out by the team of researchers of CIBER-BBN and Politecnic University of Valencia, led by, Ramón Martínez Máñez, Scientific Director of NANBIOSIS U26 NMR: Biomedical Applications II, is highlighted by the Spanish TV. This team has developed a new drug against lung cancer that, along with other therapies, eliminates cells that have been bottled prematurely without harming healthy ones. The drug has been successfully administered in mice, now it comes the challenge of finding a way to administer it without damaging the patient’s healthy organs, and they propose inserting it into a capsule that would be released[...]

“Molecular probes and gated materials in biomedical applications and communication between nanoparticles” by Ramón Martínez

Next June 8, 2020, 12 pm, Ramón Martínez Máñez, Scientific Director of CIBER-BBN and NANBIOSIS U26, give an on line seminar, hosted by Jaume Veciana and Anna Roig will from ICMAB-CSIC. The development of optical molecular probes and probes based on gated nanoparticles has been an area of interest during the last decades. Optical probes are able to transform chemical information in the environment into a suitable optical signal, usually a change in colour of fluorescence. Moreover, gated materials have also been widely used for the development of drug delivery systems. Some examples of optical probes and gated materials for[...]

A new compound removes senescent cells and reduces toxicity in cancer treatment

Scientists of NANBIOSIS unit 26 NMR: Biomedical Applications II, (of CIBER-BBN and the Universitat Politècnica de València), together with researchers from the Principe Felipe Research Center and the University of Cambridge confirm the therapeutic potential of using a new conjugated drug, Nav-Gal, in combination with chemotherapy Nav-Gal selectively removes tumourigenic senescent cells without attacking healthy cells and reduces the toxicity of platelets The accumulation of senescent cells plays a significant role in cancer pathogenesis and other diseases. However, senolytic drugs (intended to remove senescent cells) present significant toxicity, which limits their therapeutic benefits. Now, a new international study involving researchers[...]

NANBIOSIS research to fight cancer

Twenty years ago, the 4 February was declared World Cancer Day with the global challenge of cancer would not be forgotten. Since then, huge progress has been made to understand, prevent, diagnose, and treat cancer. NANBIOSIS as an ICTS (Singular Scientific and Technical infrastructures) for biomedical research plays a very important role in the fight against cancer. Some examples of the work carried out during the last year, are bellow: Unit 20 of NANBIOSIS  at VHIR, works in several proyects reletaed to cancer as  H2020-NoCanTher: magnetic nanoparticles against pancreatic cancer through the use of hyperthermia combined with conventional treatment. H2020-Target-4-Cancer: nanotherapy based on polymeric micelles directed against[...]

A new fluorescent probe for NO

Nitric oxide is a component of the pollutant nitrogen oxides (NOx) responsible of different environmental negative effects. However, due to its physiological effects, NO has been used in different therapeutic applications. Thus, the inhaled nitric oxide (iNO) is a selective pulmonary vasodilator that finds its best applications in pediatrics, by transiently improving oxygenation in respiratory failure and persistent pulmonary hypertension. The initial recommended concentration of iNO in these treatments is 20 ppm. Higher concentrations do not increase its effectiveness and are associated with a higher incidence of methemoglobinemia and formation of nitrogen dioxide. In consequence the control of iNO concentration is[...]

Not always what closes best opens better: mesoporous nanoparticles capped with organic gates

Researchers of NANBIOSIS Unit 26 NMR: Biomedical Applications II have recently published an article in the scientific journal Science and Technology of Advanced Materials, Four types of calcined MCM-41 silica nanoparticles, loaded with dyes and capped with different gating ensembles are prepared and characterized. N1 and N2 nanoparticles are loaded with rhodamine 6G and capped with bulky poly(ethylene glycol) derivatives bearing ester groups (1 and 2). N3-N4 nanoparticles are loaded with sulforhodamine B and capped with self-immolative derivatives bearing ester moieties. In the absence of esterase enzyme negligible cargo release from N1, N3 and N4 nanoparticles is observed whereas a remarkable release for N2 is obtained most likely due to the formation of an[...]
