HER2 sends a signal from its intracellular domain, activating several different biochemical pathways.

Ras activates several pathways, of which the mitogen-activated protein (MAP) kinase cascade has been well-studied.

Further components of the gram-negative cell wall may also activate other pathways, which may contribute to the overall endotoxic effect.

This activates cellular stress signaling and inflammatory pathways because of the abnormal conditions disrupting ER homeostasis.

The analog sticks and L and R shoulder buttons can be manipulated to activate various levers, elevators, and pathways to advance the player throughout the course.

These neurons activate descending pathways that synapse in the spinal cord and inhibit nociceptive cells in the dorsal horn.

When Light, particularly blue light, is involved in the regulation of fungal development, it directs the growth of fungal structures and activates metabolic pathways.

DVT formation typically begins inside the valves of the calf veins, where the blood is relatively oxygen deprived, which activates certain biochemical pathways.

When consumed by (marine) mammals, it activates neural pathways in the brain, specifically, the hippocampus.

The small T-antigen protein is also able to activate several cellular pathways which stimulate cell proliferation.
