Scientists engineer safe, virus-resistant E coli for research

Drug Discovery World

In a step forward for genetic engineering and synthetic biology, US researchers have modified E coli bacteria to be immune to infection by all natural viruses tested so far. The team used two safeguard methods to prevent the bacteria and their modified genes from escaping into the wild.

Gene Switch: A Novel Platform for Switching Genes On and Off

Roots Analysis

Overview of Gene Switch The notion that genes might be turned on and off was discovered several decades ago when studies revealed that E. coli bacteria, as well as lambda bacteriophage, can adapt to the alterations in the composition of their nutrient medium.

Johns Hopkins Researchers Identify CRISPR Dimmer

The Pharma Data

A naturally occurring system for tuning CRISPR-Cas9 expressing in bacteria, identified in a study published in Cell , could have implications for gene editing therapies as well. A CRISPR-Cas9 system has two components: the Cas9 guide RNA that directs the system to edit a particular gene, and the CRISPR “scissors” that make the cut.
