How a Protein can Inhibit Cancer Development in Mice

The researchers’ illustration of PP2A binding to ADAM17 which cleaves other proteins such as the growth factor EGF which again binds the receptor EGFR and stimulates cell growth.

In a new study, researchers have discovered how the protein PP2A can inhibit tumor growth in mice. The protein turns off an enzyme that stimulates cell growth, thus inhibiting the development of cancer.

Proteins are found throughout our cells and regulate a lot of biological processes that are important forour survival. But some of them also regulate processes that can make us sick. Now, an international research team, with researchers from the University of Copenhagen at the forefront, has achieved a much better understanding of one such protein.

In a new study, the researchers discovered how the protei...

Simpler test that can be done in doctor’s office offers results in 30 minutes. An improved urine-testing system for people suffering from kidney stones inspired by nature and proposed by researchers from Penn State and Stanford University may enable patients to receive results within 30 minutes instead of the current turnaround time of a week or more.

Kidney stones occur due to buildup of certain salts and minerals that form crystals, which in turn stick together and enlarge to form a hard mass in the kidneys...

A ‘Switch’ that turns Autoimmunity Drugs into powerful Anti-Cancer Treatments

CCI

Scientists from the Antibody and Vaccine group at the University of Southampton have discovered a way to transform antibody drugs previously developed to treat autoimmunity into antibodies with powerful anti-cancer activity through a simple molecular “switch.”

This work, published in the journal Cancer Cell, focuses on a molecule called CD40 which is present on the surface of immune cells and controls both autoimmunity and cancer. In autoimmunity, CD40 is thought to be over-stimulated, increasing the chance of the immune system attacking healthy tissues; whereas in cancer, CD40 is believed to be under-stimulated, enabling tumour cells to evade the immune system. Targeting of CD40 with antibody drugs is ongoing in therapeutic interventions for both diseases.

Accordingly, antibody...

Adding a Blend of Spices to a meal may help Lower Inflammation

In a randomized, controlled feeding study, the researchers found that when participants ate a meal high in fat and carbohydrates with six grams of a spice blend added, the participants had lower inflammation markers compared to when they ate a meal with less or no spices.

“If spices are palatable to you, they might be a way to make a high-fat or high-carb meal more healthful,” said Connie Rogers, associate professor of nutritional sciences. “We can’t say from this study if it was one spice in particular, but this specific blend seemed to be beneficial.”

The researchers used a blend of basil, bay leaf, bl...
