A “walk” in composition space for a lipid world molecular assembly, shown in simplified 3 dimensions. A point on the line signifies a specific composition along the time axis, whereby the three coordinates are amounts of the three different molecule types. A composome (pink background) is a time interval when the composition stays almost unchanged, signifying compositional replication.

Reeducating cells in the tumor microenvironment reverses some of the malignancy

Response to treatment in cancer cells: The abundance of the EGFR (top row) and HER2 (bottom row) receptors is reduced when the cells are exposed to triple therapy – Tagrisso, Erbitux and Herceptin (right column) and to the two antibodies, Erbitux and Herceptin (second from right column), but not when they are exposed to Tagrisso alone (second column from left) or to no therapy at all (left column)
