Investigators at the National Institute of Allergy and Infectious Diseases have identified physiological factors that are not diseases in the narrow sense, but that nevertheless have large effects on microbiome composition.
One of the reasons that pancreatic cancer remains such a stubbornly dismal disease is that it is extremely desmoplastic. In other words, most of a pancreatic tumor is not made up of tumor cells, but of stroma. Stroma, in turn, is a double-edged sword for the tumor cells. Its connective tissue component impedes blood flow, which is part of what makes pancreatic cancer so drug-resistant. But the lack of blood also means a lack of oxygen and nutrients, so pancreatic tumors must find alternate ways to feed themselves. That’s where nerves come in. In the Nov. 2, 2020, online issue of Cell, researchers published new insights into how innervation feeds tumors, and how to stop them from doing so.
CYBERSPACE – “We are not very good at predicting drug response in the clinic,” Ayesha Muhammad told the audience at the 2020 annual meeting of the American Society of Human Genetics (ASHG), “though it is not for lack of trying.” Nevertheless, adverse drug reactions are among the top 10 causes of in-hospital mortality.
The opening plenary abstract session at the 2020 annual meeting of the American Society of Human Genetics (ASHG) began with the definition of a new disease, identified through a new approach, and possibly leading to a new way to think about rheumatic diseases.
Under the right circumstances, a single mouse can be as good as a group of eight or 10 animals in predicting whether a tumor will respond to a drug, researchers reported at the 2020 EORTC-NCI-AACR (ENA) Molecular Targets meeting on Saturday. The single-animal approach “allows incorporation of more tumor models within the same resource constraints,” Peter Houghton told reporters at a press conference previewing ENA highlights.
