Glioblastoma multiforme (GBM) is the most common adult primary brain tumor and is comprised of a heterogeneous population of cells. It is unclear which cells within the tumor mass are responsible for tumor initiation and maintenance. In this study, we report that brain tumor stem cells can be identified from adult GBMs. These tumor stem cells form neurospheres, possess the capacity for self-renewal, express genes associated with neural stem cells (NSCs), generate daughter cells of different phenotypes from one mother cell, and differentiate into the phenotypically diverse populations of cells similar to those present in the initial GBM. Having a ...


Jnk Regulates Hipk3 Expression And Promotes Resistance To Fas-Mediated Apoptosis In Du 145 Prostate Carcinoma Cells, James Curtin, Thomas Cotter Apr 2004

Jnk Regulates Hipk3 Expression And Promotes Resistance To Fas-Mediated Apoptosis In Du 145 Prostate Carcinoma Cells, James Curtin, Thomas Cotter

Articles

Elevated endogenous JNK activity and resistance to Fas receptor-mediated apoptosis have recently been implicated in progression of prostate cancer and can promote resistance to apoptosis in response to chemotherapeutic drugs. In addition, JNK has been demonstrated to promote transformation of epithelial cells by increasing both proliferation and survival. Although numerous studies have reported a role for JNK in promoting Fas receptor-mediated apoptosis, there is a paucity in the literature studying the antiapoptotic function of JNK during Fas receptor-mediated apoptosis. Consequently, we have used the recently described specific JNK inhibitor SP600125 and RNA interference to inhibit endogenous JNK activity in the ...
