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.

PARIS – A consortium led by French clinical and scientific experts has just published results in the Journal of Experimental Medicine of a study showing the contribution of a new simplified diagnostic test in better identifying the level of contagiousness of subjects infected with SARS-CoV-2.

For most people, neither polyglutamine disorders nor neuromuscular disorders are likely to be among the things they associate with androgen receptor (AR) dysfunction. But the three are indeed linked. And researchers have reported new insights into the nature of those links that could lead to a treatment for spinal and bulbar muscular atrophy, and possibly other disorders linked to AR signaling dysfunction.

PARIS – Magnetic fields can be used to stimulate blood vessel growth, according to a new study published in Science and Technology of Advanced Materials. The discovery, by researchers from the University of Lisbon in Portugal, could lead to new treatments for cancer and help regenerate tissues that have lost their blood supply.

Researchers have shown that glucocorticoids, a type of steroid hormones, target both neuroplasticity-related genes and genes related to ciliary function in the brain. However, the effects on the different processes are mediated via different receptors, and in response to different stimuli. A study investigated the specific targets of glucocorticoids, giving new insights into the biological mechanisms of stress adaptations, and how they are linked to neural plasticity.
