What is the Meaning of PI3K/Akt Pathway?

The PI3K/Akt Pathway is a pivotal intracellular signaling cascade that transmits survival, growth, and metabolic signals from activated cell surface receptors down into the cell nucleus. This pathway is central to anabolic responses modulated by factors like insulin and certain growth factors.

What is the Origin of PI3K/Akt Pathway?

The pathway is named for its key molecular players: Phosphoinositide 3-Kinase (PI3K), which initiates the phosphorylation cascade, and its primary downstream effector, Protein Kinase B, also known as Akt.

What is the Mechanism of PI3K/Akt Pathway?

Upon upstream activation, PI3K generates signaling lipids that recruit and activate Akt, which subsequently phosphorylates numerous target proteins involved in glucose transport, protein synthesis, and inhibition of apoptotic signals. Crosstalk exists between this pathway and steroid hormone signaling, influencing cellular responsiveness.
