Definitions:

Upregulation

The process by which a cell increases the quantity of a cellular component, such as RNA or protein, in response to an external stimulus.

Receptors

Proteins on the surface or inside of cells that bind to specific molecules like hormones or neurotransmitters, triggering a cellular response.

Hormone

A chemical messenger, often produced in one region of the body of a multicellular organism and transported to another region where it signals cells to alter some aspect of growth, development, or metabolism.

Tyrosine Kinase Receptors

A type of enzyme-linked receptor on cell surfaces that phosphorylates tyrosine residues on target proteins, playing key roles in cell signaling.
