PI3K–Akt–mTOR pathway explained in an animation: growth, survival and autophagy
The description says this animation walks through the PI3K–Akt–mTOR signaling pathway step by step, from growth factors binding receptor tyrosine kinases to mTOR's role in protein synthesis, cell growth, survival and autophagy. [1]
Automatic summary · not editorially reviewed
The key findings
The description says growth factors such as insulin or IGF bind receptor tyrosine kinases to start the PI3K–Akt–mTOR cascade. [1]
The description lists PIP2-to-PIP3 conversion, Akt activation and mTOR's control of protein synthesis and autophagy as covered topics. [1]
The description names cancer, diabetes, aging and metabolic diseases as conditions where the pathway is frequently dysregulated. [1]

Growth factors starting the RTK–PI3K–Akt cascade
The description states that the pathway is activated when growth factors such as insulin or IGF bind to receptor tyrosine kinases (RTKs). This begins a signaling cascade through PI3K, Akt and mTOR. The video is said to show the role of PI3K in intracellular signaling and the conversion of PIP2 into PIP3, followed by activation of Akt, also called Protein Kinase B. These steps are presented as a schematic animation for learners.

mTOR, protein synthesis, autophagy and disease links
According to the description, the animation explains how mTOR regulates protein synthesis and cell growth. It also covers the pathway's role in metabolism and cell survival and the regulation of autophagy by mTOR. The description further says the pathway is frequently dysregulated in cancer, diabetes, aging and metabolic diseases and names clinical significance in cancer and diabetes as a topic. These are described as teaching points, not as results of a study.
