A multidisciplinary team wanted to find the best diet to slow tumor growth after a breast cancer diagnosis. Instead, they found one that accelerated it: a high-fat diet. The researchers engineered a tumor model using a human plasmalike medium to re-create a more realistic microenvironment around tumors, and this allowed them to replicate the biochemical effects of nutrients from food. They discovered a high-fat diet accelerates tumor growth and invasion and causes an increase in the enzyme MMP1, which is associated with a poor prognosis.
Pre-teens who struggle to control their video gaming habits are more likely to have psychotic-like experiences a year later, a new study has found.
McGill University researchers and colleagues at Maastricht University found that 12-year-olds who showed signs of problematic gaming were more likely to experience mild paranoia, unusual beliefs or disturbed perceptions at age 13.
Oregon Health & Science University researchers have found that certain nerves that play an integral role in the body’s “fight or flight” stress response can support pancreatic tumor growth.
These nerves, called sympathetic nerves, grow directly into pancreatic tumors and communicate with cancer cells and nearby support cells known as cancer-associated fibroblasts. This communication can change the tumor’s behavior in ways that help pancreatic cancer grow.
