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 …

Food Based Approaches For A Healthy Nutrition In Africa, Mamoudou Hama Dicko
Pr. Mamoudou H. DICKO, PhD
The latest estimates of the FAO demonstrate the problems of the fight against hunger. These problems are manifested by the ever-increasing number of chronically undernourished people worldwide. Their numbers during the 1999-2001 period were estimated at about 840 million of which 798 million live in developing countries. Sub-Saharan Africa alone represented 198 million of those. In this part of Africa the prevalence of undernourishment ranges from 5-34%, causing growth retardation and insufficient weight gain among one third of the children under five years of age and resulting in a mortality of 5-15% among these children. Malnutrition resulting from undernourishment is …

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 …
