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.

Researchers at Stanford University have connected risk-associated single nucleotide polymorphisms for both Alzheimer's disease and Parkinson's disease to their possible causal genes via single-cell investigations into epigenomic states.
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.
Anthony Wynshaw-Boris, professor and chair of the department of genetics and genome sciences at Case Western Reserve University School of Medicine, set a positive tone in his opening talk at the 2020 annual meeting of the American Society of Human Genetics (ASHG). "This is guaranteed to be the best-ever virtual ASHG annual meeting," he told the audience. The opening plenary abstract session, for one, did not disappoint. It 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.
