Overview

Collective cell invasion contributes to spread and metastasis in a variety of cancers, including glioblastoma, breast cancer, and ovarian cancer. An example of cooperative collective cell migration during normal development, the movement of the border cells during Drosophila oogenesis, has been used to investigate the nature of oncogenic collective cell invasion. In the fly ovary, the border cell cluster consists of 4-8 epithelial-derived follicle cells that surround a central pair of polar cells. During migration to the oocyte the border cells squeeze between the intervening nurse cells; individual border cells stay adhered together and their movement is coordinated as an entire unit.

Genetic screens have identified mutations in multiple genes that disrupt this process and that result in aberrant cell migration.

        fat (ft) is a tumor suppressor gene that encodes a large cadherin family transmembrane protein. It functions in the Hippo signaling pathway (as a receptor) and the Dachsous-Fat planar cell polarity pathway (as a transmembrane component). [Date last reviewed: 2019-03-07]

        Protein tyrosine phosphatase Meg (Ptpmeg) encodes a tyrosine phosphatase that interacts with the product of Eps-15. It negatively regulates border cell migration during oogenesis. It also inhibits the EGFR/Ras/mitogen-activated protein kinase signaling pathway during wing morphogenesis. [Date last reviewed: 2019-03-14]

        Epidermal growth factor receptor pathway substrate clone 15 (Eps-15) encodes a multi-domain adaptor protein involved in endocytosis. It interacts with several other endocytic factors such as those encoded by shi, stnB, Dap160 and AP-2α. It is enriched at sites of endocytosis and is required for normal synaptic bouton development and vesicle endocytosis during high frequency stimulation. [Date last reviewed: 2018-10-18]

        α Catenin (α-Cat) encodes a protein which interacts with scrib to sustain apicobasal polarity of epithelial cells. Cooperation between α-Cat, scrib and a complex of septate junctions regulates epithelial tissue growth through interaction with the Hippo pathway. [Date last reviewed: 2023-07-20]

          Symplekin (Sym) encodes a large protein that contains many protein interaction sites, and acts as a scaffold for protein complexes in the nucleus. It functions in RNA 3' end formation for both polyadenyated mRNAs and non-polyadenylated histone mRNAs. In some cells it also localizes to the cell cortex, especially the tricellular junctions of some epithelia. [Date last reviewed: 2018-10-25]
