Study evaluates biology of prostate cancer progression in African-American men
... that paint a picture of whether or not cancer has moved beyond the confines of the prostate organ. One is the adhesion molecule E-cadherin which helps cells stick to each other. Low levels of E-cadherin are associated with cancer metastasis. Expression of two other molecules, matrix metalloproteinases (M...... of Berlin.

In fact, the scientists actually found the opposite - that the absence of JNK signaling resulted in a dramatic increase i...Ann Arbor chemist wins national award for extracting sulfur from fuel
