Scientific Overview

General Overview

Art Alberts’ laboratory is studying cell signaling and cell structure, in particular the structures that allow cells to change shape and to move. The ability of a cell to move is an essential aspect of a cancer cell’s ability to metastasize, i.e., to form tumors in the body distant from the original tumor. The family of proteins called Rho, which are active in signaling within cells and have an important role in the metastasis of cancer cells, are a major focus of the experiments. Also under study are the proteins called Diaphanous-related formins, molecules that can be activated by the Rho proteins and then create various changes in the molecular “skeleton” of actin filaments within the cell. Learning how these proteins combine to regulate a cell’s structures and functions is a major goal of the research.
