Molecular Pathways

Molecular pathways are complex chains of interactions between molecules inside cells that control how cells behave, grow, and respond to their environment. Think of them as communication channels or instructions that guide processes like energy production, cell division, or immune responses. These pathways involve signals transmitted through molecules such as proteins, which activate or deactivate other molecules, leading to specific outcomes. Understanding these pathways helps scientists learn how normal cells function and what goes wrong in diseases like cancer, enabling the development of targeted treatments.
