Cancer begins in your cells, which are the building blocks of your body. Normally, your body forms new cells as you need them, replacing old cells that die. Sometimes this process goes wrong. New cells grow even when you don't need them, and old cells don't die when they should. These extra cells can form a mass called a tumor. Tumors can be benign or malignant. Benign tumors aren't cancer while malignant ones are. Cells from malignant tumors can invade nearby tissues. They can also break away and spread to other parts of the body.

Epigenetics May Spark Tumors Without DNA Mutations

Scientists from the CNRS are part of a research team that has found that epigenetic changes, or modifications that affect the regulation of gene expression, can be the sole cause of cancer, one of the world's leading causes of death.

PI3K Enzyme's Dual Accelerator and Brake Mechanisms Uncovered

A group of researchers have expanded conventional knowledge on a critical enzyme that controls cell migration. In a recent publication in the journal Nature Communications, they reported that phosphoinositide 3-kinase (PI3K) not only acts as an accelerator to prompt cell motility, but it also has a built-in brake mechanism that impedes migration.

Study Unravels How Tumors Evade Immune Response by Targeting T Cells

Tumors actively prevent the formation of immune responses by so-called cytotoxic T cells, which are essential in combating cancer.

Study Uncovers Cells' Surprising Strategy to Control Signaling Pathways

Healthy cells respond appropriately to changes in their environment. They do this by sensing what's happening outside and relaying a command to the precise biomolecule in the precise domain that can carry out the necessary response.

Nutrient Deprivation Induces Embryonic Diapause in Hungry Mouse Mums

It's challenging to sustain a pregnancy when food is short, or conditions are otherwise tough. That's why many mammalian embryos can postpone their growth to get through periods of environmental stress and then re-enter development when conditions improve.
