Better Recovery

A University of California, Los Angeles-led team has found turning off the CCR5 gene could improve recovery after a stroke, according to Scientific American.

This Week in PNAS

In PNAS this week: chromosomal features of maize, adaptations in the vinous-throated parrotbill, and more.

In a set of new studies, members of an international team mapped gene variation, expression, and regulatory interactions in developing and adult human brains.

The funding is being provided to a number of early-career investigators and collaborative research groups using genomics and other technologies.

The partners will use a $5M NCI grant to add seven biomarkers to an EGFR electrochemical assay for non-small-cell lung-carcinoma.

The team said it will partner with startup Early Diagnostics to commercialize the assay, which integrates DNA methylation analysis and computational technology.

The nucleic acid diagnostic platform they are developing doesn't require expensive optics, and it could be available as a manufacturing prototype in about a year.

The projects are organized by the Eliminate Cancer Initiative, the National Brain Tumor Society, and the Pediatric Brain Tumor Foundation.

Investigators have applied the platform to isolating viable CTCs in droplets, in which molecular and enzymatic activity can be studied.

The technology uses a conducting polymer-based electrochemical chip with an array of electrodes and employs an electrical field to release and detect mutations.
