Chromosomes

Pre-existing chromosomal instability may predict response to paclitaxel

Sep. 14, 2021
By Subhasree Nag
In a recent study, researchers led by Beth Weaver from the University of Wisconsin, Madison (UW-M) show that paclitaxel treatment in breast cancer patients increased cell division with chromosome missegregation to induce cytotoxicity.

Metabolomics study reveals dementia-linked metabolites

Sep. 13, 2021
By John Fox
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.

At WCLC, early steps toward success against SCLC

Sep. 10, 2021
By Anette Breindl
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).

DNA and antibodies

Self-made antibodies can go big and could, perhaps, be cheap

Sep. 10, 2021
By Anette Breindl
Delivering antibodies in the form of their DNA could enable their therapeutic use under several circumstances where traditional antibodies fall short. One of those is resource-poor settings where the current cost of antibodies makes them a nonstarter. Perhaps the largest opportunity to expand antibody use in such settings is for HIV, where broadly neutralizing antibodies have the potential to be the next best thing to a vaccine or a cure – if they can be made to last, for cheap.

Self-made antibodies could address vexing health questions

Sep. 9, 2021
By Anette Breindl
Monoclonal antibodies are a triumph of modern medicine. They are also too expensive to be a standard therapy in all but the wealthiest countries. “Having 10% or 15% of your population on antibodies is not sustainable even in wealthy countries,” Rachel Liberatore told BioWorld. Liberatore is director of research and development at Renbio Inc., which is testing the intramuscular delivery of antibody-encoding DNA to prevent and treat infections, including SARS-CoV-2 and HIV.

Gut bacteria accumulate multiple therapeutic drugs

Sep. 9, 2021
By Nuala Moran
The impact that the microbiome has on drug metabolism is further elucidated in new research showing for the first time that bacteria in the gut accumulate and store drug compounds.

AAV integration frequencies "surprisingly high," study finds

Sep. 8, 2021
By Anette Breindl
Researchers at Oregon Health and Science University have used mouse models to estimate the frequency at which gene therapies delivered by adeno-associated virus (AAV) vectors integrated into host DNA, and come up with an estimate of up to roughly 3% – a number that is orders of magnitude higher than previous estimates and would translate into several hundred million cells with integrated viral vectors in an adult liver, assuming that 10% of cells took up the transgene.

Analysis boosts genomics-driven precision medicine

Sep. 7, 2021
By John Fox
The most comprehensive international collaborative analysis to date of the impact of variants on gene expression has revealed thousands of previously unknown regulatory genomic regions controlling disease-linked genes, representing a major advance in genomics-driven precision medicine.
