The topography of Titan, the largest of moon of Saturn, seems serene in Cassini mission images, but lakes of liquid methane that pock the landscape were likely formed by explosive, pressurized nitrogen just under the moon’s crusty surface, according to research published Sept. 9 in Nature Geoscience.

Study reveals that E-cadherin, a molecule that allows cells to stick to each other, promotes metastasis in the most common type of breast cancer

Researchers at the Johns Hopkins Kimmel Cancer Center discovered that a cell adhesion protein, E-cadherin, allows breast cancer cells to survive as they travel through the body and form new tumors, a process termed metastasis. Their conclusions, obtained through laboratory experiments and in mouse models, help explain how metastasis works in the most common form of breast cancer, invasive ductal carcinoma. E-cadherin appears to limit molecular stresses within the cancer cells and allow them to survive long enough to form new tumors. The finding, published online in the Sept. 4 issue of Nature, could lead to new ways to prevent breast cancers from recurring in patients.

“Previously, researchers thought that it was essential for cancer cells to lose E-cadherin in order to metastasize,” says study leader Andrew Ewald, Ph.D., professor of cell biology and co-director of the Cancer Invasion and Metastasis Program at Johns Hopkins Kimmel Cancer Center. “This was difficult to reconcile with the fact that breast tumors in patients typically continue to express E-cadherin. Our study was designed to test the role of this protein during metastasis.”
