Tumors

Scientists have long known that the engine room of cells, the mitochondria, play an essential role in the growth of cancer. Now, they have the clearest picture yet of just how the energy organelles form complex structures within lung cancer tumors.

Cancer tumors are particularly adept at evading the body’s immune response, making treatment difficult. A new study has genetically engineered a common gut bacteria, enabling it to seek out and destroy cancer tumors from the inside.

Detecting circulating tumor cells among healthy blood cells is notoriously hard. Now an easy-to-use device can ID even a small number of cancer cells, potentially providing a huge breakthrough in non-invasive early detection, monitoring and treatment.

Using the same whipping siphon used in the culinary world, researchers have created a food-based foam that can be injected directly into tumors. The foam contains oxygen, which makes tumors more susceptible to chemotherapy and radiation treatments.

Immunotherapy is a promising cancer treatment, but getting it to work against solid tumors is difficult. A new study has not only identified a drug that’s effective against solid tumors, but may have uncovered a reason that immunotherapy often fails.

Scientists at the University of California San Francisco have found a way to fight one of the most common cancer-causing mutations. The new drug puts up an “eat me” marker that can help the immune system or other drugs find and kill the cancer.

Researchers have created a new mRNA vaccine for cancer that’s designed to carry its cargo to the lymph nodes rather than the liver. Tests in mice showed significant inhibition of the tumors, with complete remission in a decent percentage of cases.

Scientists in Spain have uncovered a mechanism behind why some cancer patients don’t respond well to treatments – and more importantly, found a “weak spot” that could be targeted by existing drugs.

Researchers have found that adding a booster protein can significantly improve the outcome of cancer immunotherapy. Tests in mice showed the protein produced 10,000 times more cancer-targeting immune cells, with all mice surviving the experiment.

A study has analyzed the genomes of cancer cells from 12,000 patients identifying 58 new mutational signatures that offer clues to novel causes of cancer. The findings offer a whole trove of new resources to guide future studies on cancer treatments.

Analysis of an ongoing project that has been tracking the health of nearly one million women in the UK for more than 20 years has found no association between increased risk of brain tumors and cell phone use.

Heightened tissue growth can result when cells come under tension, and a new study on cancer cells has pinpointed the biological mechanism that drives this process, which the authors believe can be targeted to prevent tumor development.
