New infrared marker for bio-imaging

The recently developed fluorescent protein Amrose is now being used for advanced near-IR imaging procedures. With the aid of a novel evolutionary platform technology, scientists have developed this infrared marker as part of a combined effort to improve the quality of tissue imaging.

Knowing how bacteria take out trash could lead to new antibiotics

A team of scientists has reconstructed how bacteria tightly control their growth and division, the cell cycle, by destroying specific proteins through regulated protein degradation. All organisms use controlled protein degradation to alter cell behavior in response to changing environment. A process as reliable and stable as cell division also has to be flexible, to allow the organism to grow and respond. But little has been known about the molecular mechanics of how this works.

A 'clear' choice for clearing 3-D cell cultures

Scientists have hailed recent demonstrations of chemical technologies for making animal tissues see-through, but a new study is the first to evaluate three such technologies side-by-side for use with engineered 3-D tissue cultures.

A new synthetic amino acid for an emerging class of drugs

Scientists have developed a new amino acid that can be used to modify the 3D structure of therapeutic peptides. Insertion of the amino acid into bioactive peptides enhanced their binding affinity up to 40-fold. Peptides with the new amino acid could potentially become a new class of therapeutics.

Throwing a loop to silence gene expression

Cells attach so-called 'epigenetic' signals to their genome to select which part of their genetic information is used. Scientists have now systematically investigated the interplay between components of an epigenetic network and developed a mathematical model that describes how it operates. The results can be used to predict how cellular gene expression programs respond to drug treatment or other perturbations of the cellular environment.
