Researchers have discovered another set of pore-like holes, or channels, traversing the membrane-bound sac that encloses the deadliest malaria parasite as it infects red blood cells. The channels enable the transport of lipids -- fat-like molecules -- between the blood cell and parasite, Plasmodium falciparum. The parasite draws lipids from the cell to sustain its growth and may also secrete other types of lipids to hijack cell functions to meet its needs. from Top Health News -- ScienceDaily https://ift.tt/2BJF7WG via IFTTT

More than 200 genes with novel and known roles in glioblastoma - the most aggressive type of brain cancer - offer promising new drug targets. Researchers engineered a new mouse model to show for the first time how a mutation in the well-known cancer gene, EGFR initiates glioblastoma, and works with a selection from more than 200 other genes to drive the cancer. from Top Health News -- ScienceDaily https://ift.tt/3hSEZ6B via IFTTT

Of the CRISPR-Cas9 tools created to date, base editors have gotten lots of attention because of their seemingly simple editing: they neatly replace one nucleic acid with another, in many cases all that should be needed to fix a genetic disease. Scientists have now determined the structure of the latest base editor as it swaps out nucleic acids, showing why it can go off target but also how it can be improved. from Top Health News -- ScienceDaily https://ift.tt/3150TNq via IFTTT
