But analysis of stem cell expression before and after treatment revealed that even as some anti-cancer treatments shrank tumors, they increased expression of Nanog and BMI1. (medindia.net)
These treatments were not enough to completely inhibit tumor growth, and the cancer stem cell markers were still present," Dr. Vasko said. (medindia.net)
Use of the agents Velcade and Docetaxel led to the most significant increase in stem cell markers within the treated tumor, while ifosfamide and Avastin inhibited expression of the markers in this cancer subtype. (medindia.net)
Dr. Vasko doesn't know how this happens, but theorizes that "dying cells could secrete a lot of factors that induce expression of stem cell markers in other cancer cells. (medindia.net)
