A protein
in the TOR signalling pathway, called SREBP, controls the flow of messages to the
endoplasmic reticulum telling it to expand — and could allow cancer cells to produce enough proteins and lipids to fuel their non-stop growth.
This information flow may also be followed through the cell as it travels from the DNA
in the nucleus, to the Cytoplasm, to the Ribosomes and the
Endoplasmic Reticulum, and finally to the Golgi Apparatus, which may package the final products for export outside the cell.
