In the October 1 issue of G&D, Dr. Guillermo Oliver (St. Jude Children’s Research Hospital) and colleagues present new evidence to resolve a century-old debate over the origin of the mammalian lymphatic vasculature.

MicroRNA convicted of triggering metastasis

The jury is in: microRNAs can cause tumors to metastasize. These tiny molecules fine-tune protein production and play a powerful role in biological processes ranging from development to aging. Now scientists have proved that they can prompt otherwise sedentary cancer cells to move and invade other tissues.

Scientists discover control mechanism for metastasis

Metastasis – when cancer cells dissociate from the original tumor and migrate via the blood stream to colonize distant organs – is the main cause of cancer death. A team of scientists at the Weizmann Institute of Science has now revealed new details about the mechanisms controlling metastasis of breast cancer cells.

How tumor cells home in on the lymphatic system

A Swiss-based research team has published a new mechanistic description of how tumor cells migrate to the lymphatic system in the early stages of tumor metastasis. This new understanding holds significant potential for developing anti-metastasis therapies.
