Research shows how immune cells act to limit tumor development

How does the immune system act to limit tumor development? Using in vivo imaging tools, scientists from the Institut Pasteur and Inserm described the spatiotemporal activity of tumor-infiltrating T lymphocytes, both locally and remotely.

Researchers visualize first structure of key enzyme that helps make triglycerides

The first structure of a lipin enzyme, which carries out an important step in the production of triglycerides, the main reservoir for long-term energy storage, will help scientists to better understand how lipins regulate the production of triglycerides.

Exploiting careless cancer cells to develop new drugs

Could the ability of cancer cells to quickly alter their genome be used as a weapon against malignant tumors? Researchers at Uppsala University have succeeded in developing a substance that has demonstrated promising results in experiments on both animal models and human cancer cells.

A copper-binding protein influences breast cancer cell migration

Researchers at Chalmers University of Technology, Sweden, have shown that the Atox1 protein, found in breast cancer cells, participates in the process by which cancer cells metastasise.

'Primitive' stem cells shown to replace and repair damaged blood vessels in the retina

Johns Hopkins Medicine scientists say they have successfully turned back the biological hands of time, coaxing adult human cells in the laboratory to revert to a primitive state, and unlocking their potential to replace and repair damage to blood vessels in the retina caused by diabetes.

New toolkit to repair DNA breaks linked to aging, cancer and MND discovered

A new 'toolkit' to repair damaged DNA that can lead to aging, cancer and Motor Neurone Disease has been discovered by scientists at the Universities of Sheffield and Oxford.

Breakthrough technology identifies proteins' nearest neighbors on cell surfaces

When corporate partners in the Princeton Catalysis Initiative sat down two years ago with David MacMillan, they presented him with a biological challenge at the heart of potential cancer medicines and other therapeutics: which proteins on a cell's surface touch each other?

Research shows how Chlamydia pathogen invades human cells

Together with scientists from Paris and Munich, a team of researchers working under Prof. Dr. Johannes Hegemann and Dr. Katja Moelleken has published these findings in the journal Proceedings of the National Academy of Sciences of the United States of America.

New repair mechanism for alcohol-induced DNA damage discovered

Researchers of the Hubrecht Institute in Utrecht, The Netherlands, and the MRC Laboratory of Molecular Biology in Cambridge, United Kingdom, have discovered a new way in which the human body repairs DNA damage caused by a degradation product of alcohol.

Chemists develop promising molecular tool to target cell immortality's underlying gears

One of the hallmarks of cancer is cell immortality. A Northwestern University organic chemist and his team now have developed a promising molecular tool that targets and inhibits one of cell immortality's underlying gears: the enzyme telomerase.

Inhibiting energy production in immune T-cells allows some tumors to escape treatment

A small molecule that inhibits energy production in immune T-cells allows some tumors to escape treatment with an immunotherapy called PD-1 blockade therapy, says a study in mice published today in eLife.

Observation of telomerase activity at a single-molecule level using 'optical tweezers'

Stem cells involved in replenishing human tissues and blood depend on an enzyme known as telomerase to continue working throughout our lives. When telomerase malfunctions, it can lead to both cancer and premature aging conditions.

Study provides new insight on neural processes behind our desire for revenge

New insight on the neural processes that drive a desire for revenge during conflict between groups has been published today in the open-access journal eLife.

Study reveals the mechanisms in our brains that lead to satiety after a meal

You just finished a good meal and are feeling full? Researchers from the CNRS, Inrae, University of Burgundy, Université de Paris, Inserm, and University of Luxembourg have just revealed the mechanisms in our brains that lead to this state.

New method maps 3D forces exerted by tiny cell clusters

A team of researchers has developed a new technique to map the three-dimensional forces that clusters of human cells exert on their surrounding environment. The method could potentially help scientists better understand how tissue forms, how wounds heal or how tumors spread.
