Bacteria help discover human cancer-causing proteins

A team led by researchers at Baylor College of Medicine and the University of Texas at Austin has applied an unconventional approach that used bacteria to discover human proteins that can lead to DNA damage and promote cancer. ...

To repair DNA damage, plants need good contractors

When a building is damaged, a general contractor often oversees various subcontractors—framers, electricians, plumbers and drywall hangers—to ensure repairs are done in the correct order and on time.

How invading jumping genes are thwarted

Since Carnegie Institution's Barbara McClintock received her Nobel Prize on her discovery of jumping genes in 1983, we have learned that almost half of our DNA is made up of jumping genes—called transposons. Given their ...

Biologists discover source for boosting tumor cell drug sensitivity

DNA-damaging agents, or "DDAs," make up the most widely used group of cancer drugs. Yet their therapeutic success has been curtailed by drug resistance—either present in cancer cells from the disease onset or arising during ...

Switching DNA and RNA on and off

DNA and RNA are naturally polarised molecules containing electric dipole moments due to the presence of a significant number of charged atoms at neutral pH. Scientists believe that these molecules have an in-built polarity ...

CRISPR-based tool maps gene function in human cells

UC San Francisco scientists have used a high-throughput CRISPR-based technique to rapidly map the functions of nearly 500 genes in human cells, many of them never before studied in detail.

Mayo researchers find off/on switch for DNA repair protein

Damage to DNA is a daily occurrence but one that human cells have evolved to manage. Now, in a new paper published in Nature Structural & Molecular Biology, Mayo researchers have determined how one DNA repair protein gets ...

Timing is key for bacteria surviving antibiotics

For bacteria facing a dose of antibiotics, timing might be the key to evading destruction. In a series of experiments, Princeton researchers found that cells that repaired DNA damaged by antibiotics before resuming growth ...

Molecular brake on human cell division prevents cancer

Researchers at Karolinska Institutet, Sweden, and the University of Sussex, England, have discovered that the process of copying DNA generates a brake signal that stalls cell division. This molecular brake ensures that the ...
