PARIS – A Russian research consortium has discovered that coating magnetic nanoparticles with a non-magnetic silica shell significantly decreased the viability of cancer cells in a low frequency alternating magnetic field. This discovery may augur new therapeutic prospects for nanotechnology combined with medical imaging.

Low-grade gliomas with mutated isocitrate dehydrogenase-1 (IDH1) produced and secreted higher levels of the cytokine granulocyte colony-stimulating factor (G-CSF) than other glioma types, which improved their antitumor immune response in animal models.

Trimers of nanobodies, a simpler form of antibody made by some animal species, were effective at preventing and treating COVID-19 in preclinical studies, researchers reported in the Sept. 22, 2021, issue of Nature Communications. The findings, along with others, could form the basis of an inhaled biologics treatment for COVID-19 and, ultimately, other respiratory diseases.

Although targeted therapies are prescribed on the basis of a patient's molecular makeup, they do not work every time. And in those instances where they do work, they basically stop working every time. In response, researchers have developed a number of systems whose goal it is to predict which drugs will be effective for an individual patients.

Researchers have retrospectively divided more than 16,000 non-small-cell lung cancer (NSCLC) patients with EGFR mutations into four structure-based subgroups, and looked at how the members of each subgroup fared depending on which EGFR inhibitor they were given.

PARIS – Researchers at the Institute for Surface Technologies and Photonics in Weiz, Austria, and the Institute of Scientific and Industrial Research Osaka University, Japan, have invented new ultra-flexible health monitoring patches that use harvested bio-mechanical energy. “These new devices represent a wireless e-health patch for accurate pulse and blood pressure monitoring,” Andreas Petritz, from the Institute for Surface Technologies and Photonics (the materials research unit of Joanneum Research FmbH), told BioWorld.

A comprehensive nontargeted metabolomics analysis has revealed previously unknown classes of disease-linked metabolites in whole blood samples from dementia patients, which may have significant therapeutic implications for managing the untreatable common cognitive disorder.

Driven by advances in scientific understanding, the treatment of non-small-cell lung cancer (NSCLC) has begun to see successes one subtype at a time. At the 2021 World Conference on Lung Cancer (WCLC), which is currently being held in virtual format, researchers were optimistic that the same path would be possible for small-cell lung cancer (SCLC).

In studies that give new insights into both developmental biology and the origins of melanoma, investigators at Memorial Sloan-Kettering Cancer Center and Weill Cornell Medical College have identified the activity of chromatin remodeling protein ATAD2 as necessary for cells with the oncogenic mutation V600E to give rise to melanomas. Involvement of epigenetic factors in cancers, or their targeting, is not new in cancer – as HDAC inhibitors as well as newer drugs such as the EZH2 inhibitor Tazverik (tazemetostat, Epizyme Inc.) demonstrate. But to Richard White and his colleagues, the point of their work is not so much about individual targets.

Investigators at MIT have identified a protein capable of delivering its own mRNA to cells, and engineered that protein to deliver mRNA sequences of their choosing. In a mouse model, the team used their approach to deliver the mRNA for two different proteins.
