Researchers unlock mechanism of drug resistance in aggressive breast cancer

Researchers unlock mechanism of drug resistance in aggressive breast cancer

UNC Lineberger researchers find how triple negative breast cancer cells are able to bypass treatment with trametinib, an FDA-approved drug. The researchers also used lab models of breast cancer to test a potential treatment approach that could prevent resistance.

Engineering Control of Cellular Proteins - An Optogenetics Breakthrough

Engineering Control of Cellular Proteins - An Optogenetics Breakthrough

UNC scientists expand the use of light to control protein activity in cells. Klaus Hahn and Nikolay Dokholyan have published a paper in Science, detailing how they use light- or ligand-sensitive domains to modulate the structural disorder of diverse proteins, thereby generating robust allosteric switches. The title of the paper is "Engineering extrinsic disorder to control protein activity in living cells."

Erasing memory using synaptic optogenetics

The Hahn, Kuhlman and Kasai labs developed a genetically encoded probe that can label and optically erase synapses that were enlarged or generated by motor learning. Dense labeling of synapses was found in a small subset of pyramidal neurons, and irradiation with blue light erased motor memory.

A BRAIN Initiative first: new tool can switch behavior ‘on’ and ‘off’

A BRAIN Initiative first: new tool can switch behavior ‘on’ and ‘off’

Using a new ‘chemogenetic’ technique invented at UNC, scientists turn neurons ‘on’ and ‘off’ to demonstrate how brain circuits control behavior in mice. This unique tool – the first to result from the NIH BRAIN Initiative – will help scientists understand how to modulate neurons to more effectively treat diseases.
