Arsenic-loving bug theory disproved

Posted Jul 8, 2012

In a paper published in Science magazine that is getting wide play in national media, a group of researchers that includes Marshall Reaves, Joshua Rabinowitz, and Leonid Kruglyak from Princeton University, disproves the sensational claim (reported last year in Science) that, under phosphate limiting conditions, arsenate could replace phosphorous in the DNA of a microbe.

Adult stem cells are a small number of weakly differentiated cells that maintain organ tissue through self-renewal and production of differentiated cells. In the past two decades rare cells that possess stem cell markers have been identified in leukemias and solid tumors, called cancer stem cells. Currently it is debated whether tumors are fuelled by these cancer stem cells  or whether most cells in a tumor can maintain its growth. In this talk I present evidence from  human cancer clinical trials that cancer stem cells with the properties of adult stem cells do not  exist.
