Cancer

Blocking a specific protein complex (mTORC2) prevents prostate tumor formation in mice with a deleted PTEN gene. Inhibition of this complex in normal prostate cells, however, appears to have no effect, suggesting that the protein complex may be a future target for drug development.

Scientists have known for the last decade that a link exists between wound healing and cancer. Now scientists in the lab of Whitehead Institute Member Robert Weinberg have discovered the process by which tumors hijack normal wound-healing processes and use them for their own purposes.

Scientists know a great deal about how tumors originate and develop, but relatively little about how cancer manages to metastasize and invade distant tissues and organs.
