With seedlings and shoots still poking their leafy tops out of the soil, it's hard to read the newly published research of Brown University biologist Alison DeLong without musing that it provides a deeper understanding of what puts the spring in spring. DeLong's paper, published in advance online April 21 in PLoS Genetics, reveals fertile new insights into the intricate network of proteins that controls plant growth and development, particularly at the seedling stage. But the research also...

Plant biologists have discovered the last major element of the series of chemical signals that one class of plant hormones, called brassinosteroids, send from a protein on the surface of a plant cell to the cell's nucleus. Although many steps of the pathway were already known, new research from a team including Carnegie's Ying Sun and Zhiyong Wang fills in a missing gap about the mechanism through which brassinosteroids cause plant genes to be expressed. Their research, which will be...

U.S. and Singaporean scientists say a protein found in a fruit fly's brain, with a counterpart in mammals, can apparently prevent brain tumors from forming. Researchers at Duke University and the National University of Singapore's Graduate Medical School have found the fruit fly protein PP2A suppresses brain tumor formation and controls the balance of self-renewal and differentiation of neural stem cells, said Assistant Professor Hongyan Wang. Given that mechanisms for stem cell division in...

Scientists have uncovered an unexpected functional link between a phosphatase known to act as a tumor suppressor and BCR/ABL, a kinase that is intimately linked with cancer development and progression in specific forms of leukemia. The study, published in the November issue of Cancer Cell, provides fresh insight into the molecular mechanisms that are involved in induction and progression of chronic myelogenous leukemia (CML), and suggests a new strategy that may be an effective therapy for...
