Growth factors in single cells counted for the first time

26-Feb-2019

Whether healthy or diseased, human cells exhibit behaviors and processes that are largely dictated by growth factor molecules, which bind to receptors on the cells. For example, growth factors tell the cells to divide, move, and when to die--a process known as apoptosis. When growth factor levels ...

Scientists sharpen their molecular scissors and expand the gene editing toolbox

26-Feb-2019

Wake Forest Institute for Regenerative Medicine (WFIRM) scientists have figured out a better way to deliver a DNA editing tool to shorten the presence of the editor proteins in the cells in what they describe as a "hit and run" approach. CRISPR (clustered regularly interspaced short palindromic ...

The 'blue' in blueberries can help lower blood pressure

25-Feb-2019

A new study has found that eating 200g of blueberries every day for a month can lead to an improvement in blood vessel function and a decrease in systolic blood pressure in healthy people. Researchers from King's College London studied 40 healthy volunteers for one month. They were randomly given ...

Cracking colibactin's code

Examining a compound damaging DNA to understand its connection to cancer

19-Feb-2019

For more than a decade, scientists have worked to understand the connection between colibactin, a compound produced by certain strains of E. coli, and colorectal cancer, but have been hampered by their inability to isolate the compound. So Emily Balskus instead decided to focus on the mess it ...
