Researchers make gains in understanding antibiotic resistance

Howard Hughes Medical Institute researchers chiseling away at the problem of antibiotic resistance now have a detailed explanation of how the drugs' main cellular target in bacteria evolves to become resistant to some of these medications.

New ideas for creating a new generation of oral medications to treat infertility

Researchers now have a much better picture of how follicle-stimulating hormone (FSH), one of the most frequently used fertility drugs, works, and with it new ideas for creating a new generation of oral medications to treat infertility.

Findings could lead to new knowledge that could speed the development of drugs to block botulism or tetanus toxins more rapidly

The first detailed structure of a botulism toxin attached to its target protein reveals that the toxin snakes the protein around itself — a sort of “reverse anaconda” — to recognize the receptor.

Wide angle X-ray scattering (WAXS) could help produce lead drugs for disease therapy

Structural changes in proteins can now be seen in increased detail, using a new application of an existing technique. The application, developed at the U.S. Department of Energy's Argonne National Laboratory, could help produce lead drugs for disease therapy.

Important advance in understanding the structure of phage viruses

An important advance in understanding the structure of phage viruses, which infect and destroy bacteria, has been made by a team of scientists from Oxford and Finland, which could help develop new strategies to combat bacterial infections.

Protein points to anticancer drug targets

A unique tail at one end of a protein called Ubc12 stabilizes a molecular workshop that assembles the “on-switch cells” used to accelerate cell replication.

High-resolution images reveal the molecular rearrangements that rotavirus uses to break into cells

High-resolution images constructed by researchers at Children's Hospital Boston and Harvard Medical School reveal the molecular rearrangements that rotavirus – the most common cause of severe, dehydrating diarrhea and vomiting in children worldwide – uses to break into cells.

Researchers map structure of anti-cancer molecule and open the door to the creation of more effective cancer treatments

Scientists at Emory University, in collaboration with researchers at three national laboratories, have solved the structural puzzle of how an emerging class of promising cancer drugs works to halt cell division. The discovery potentially opens the door to the creation of more effective cancer treatments.

Automated science speeds solution of Human Genome data

Scientists in Argonne's Biosciences Division are automating and accelerating the complex processes that coax a protein to reveal its structure so they can learn the role Nature assigned it.

Relatively difficult for the AIDS virus to develop resistance to the drug, tenofovir, or the DAPY (diarylpyrimidine) family of compounds

HIV is a moving target, unpredictably changing direction to elude anti-AIDS drugs, but researchers at Rutgers are clearly on the track of solutions to combat HIV drug resistance.

A new technique for engineering protein crystals is helping scientists figure out the three-dimensional structures of some important biological molecules

A new technique for engineering protein crystals is helping scientists figure out the three-dimensional structures of some important biological molecules, including a key plague protein whose structure has eluded researchers until now. The technique, developed with support from the National Institute of General Medical Sciences (NIGMS) of the National Institutes of Health (NIH), promises to help pharmaceutical companies develop more effective drugs to treat various diseases by tailor-making molecules to "fit" a protein's shape.
