Caption: An artist's representation shows how stress signals from cancer cells prompt similar signals in neighboring cells, aiding and abetting tumor growth. Left: To survive in a harsh environment (low oxygen, nutrient deprivation), tumor cells produce constant endoplasmic reticulum (ER) stress response. Center: These ER stress signals are transmitted to nearby macrophages – white blood cells charged with recognizing and removing tumor cells and pathogens. The macrophages react with their own ER stress signals, initiating an inflammation response. Right: The resulting macrophage-amplified inflammation encourages more tumor growth.
