Cancer metastasis causes approximately 90% of all cancer-related death and
independent of the advancement of cancer therapy, a majority of late stage
patients suffers from metastatic cancer. Metastasis implies cancer cell migration
and invasion throughout the body. Migration requires the formation of pseudopodia
in the direction of movement, but a detailed understanding of this process and
accordingly strategies of prevention remain elusive. Here, we use quantitative
proteomic profiling of human cancer pseudopodia to examine this mechanisms
essential to metastasis formation, and identify potential candidates for
pharmacological interference with the process. We demonstrate that Prohibitins
(PHBs) are significantly enriched in the pseudopodia fraction derived from cancer
cells, and knockdown of PHBs, as well as their chemical inhibition through
Rocaglamide (Roc-A), efficiently reduces cancer cell migration.
