Microtubule-associated kinase DCAMKL-1 a novel target for anti-CSC-based strategies?

Scientists discover stem cell protein linked to cancer growth, Kerentech, May 23, 2009. Excerpt:
Researchers have studied stem cell proteins for years, but Houchen and Anant said they not only found a new cancer protein, but discovered how the protein works to turn off a natural tumor suppressor and turn on a cancer-causing gene.
The results of their research will be published in an upcoming issue of the journal Gastroenterology.

The latest work involves a new stem cell protein. Houchen and Anant discovered that this protein was responsible for regulating a natural tumor suppressor. It is the first such evidence of a stem cell protein regulating a tumor suppressor. When the protein, which is found in cancer, was increased, it caused the tumor suppressor to go down and the tumor grew in research models. When the protein was reduced or "knocked down," the level of tumor suppressor went up and the tumor stopped growing. Scientists also found that when they stopped the protein, the expression of a cancer-causing gene also went down.
