Biological pathway analysis

Definition

Biological pathway analysis is a method used to study and understand the interactions and functions of biological pathways, which are series of actions among molecules in a cell that lead to a certain product or change in the cell. This analysis helps researchers identify the roles of specific genes, proteins, and metabolites within the context of cellular processes and diseases. It is essential for systems biology approaches, as it provides insights into how cellular networks operate and how they can be influenced by various factors.
