Researchers build diagram of cell cycle clock
...e. A change in the cells environment can trigger a cascade of changes inside the cell, all of which can be captured in another snapshot. Though this provides information about what is going on in cell from one moment to the next, it doesnt tell what is regulating the changes. Understanding how biological pro...Reproduction without fertilization?
...on of one gene in a single gamete can initiate the cascade of events normally associated with fertilization. Fertilization is the process by which two gametes, be it an egg and a sperm in mammals or an mt+ cell and an mt- cell in green algae, fuse to create a new individual, called a zygote. The zygotic geno...Researchers identify pathogen-specific gene response in human immune cells
... for presentation to the T-cell, thus initiating a cascade of immune events that fight infection. "What weve discovered is that dendritic cell maturationas a result of its recognition of a pathogenis highly specialized," says Hacohen. "The dendritic cell fine tunes its response based upon the nature of the...Geologists develop new database using GIS for study of evolution of continents
...plutons and the regions they are in." "We have a cascade of scales," Wilson said. The GIS allows the scientists to look for spatial relationships within the data. For example, they can zoom into an outcrop (any rock formation in the woods or fields or on road sides) and determine its attributesthe mineral...Phase 3 psoriatic arthritis data for ENBREL (etanercept) announced at a national scientific meeting
...ortant role in both normal immune function and the cascade of reactions that cause the inflammatory process of RA and psoriatic arthritis. ENBREL competitively inhibits binding of TNF molecules to the TNF receptor sites. The binding of ENBREL to TNF renders the bound TNF biologically inactive, resulting in s...New Phase 2 study shows ankylosing spondylitis patients respond to ENBREL (etanercept)

...cific chemicals in the form of odors, initiate the cascade of electrochemical events that produce the sense of smell. Writing in the Nov. 27 issue of the online version of the Proceedings of the National Academy of Sciences, Zwiebel and his colleagues at Vanderbilt, the University of Illinois, Urbana-Champai...Gene triggers stem cell differentiation in the intestine
...begin to build a framework of understanding of the cascade of events, involving many genes, that governs this process. Such an understanding could have considerable clinical importance, said Zoghbi. These cells are important in our handling of metabolites absorbed from food and our response to infections, sh......DAPK contains a "death domain" that can initiate a cascade of molecular events that cause a cell to commit suicide. This process, called programmed cell death or apoptosis, is programmed into all but the most primitive of cells. It causes the cell to shut down in an orderly manner so that its contents can be...U. of Colorado researchers identify switch that controls aging in worms
... that DAF-16 enters the cell nucleus, triggering a cascade of biochemical events that lead to a longer lifespan. There is a good possibility scientists could develop a pharmaceutical intervention that would trigger translocation of DAF-16 into the cell nucleus of a variety of animals, including humans, said ...Gene therapy and sickle cell disease: Religious perspectives
... red blood cells did not sickle, and the resulting cascade of problems was not present. As a priest who ministers to an ethnic group in which globin-gene disorders are common, I find the results of these experiments heartening. This could be the first step in effectively treating a debilitating and someti...Required activation 'cascade' identified for p53 tumor-suppressor protein
...that p53's ability to suppress tumors depends on a cascade of molecular changes that occur after the molecule binds to the DNA," says Shelley L. Berger, Ph.D., an associate professor in molecular genetics and senior author on the report. "The data also outline a general mechanism by which many DNA-binding pr......previously identified components of the adipogenic cascade were unable to induce adipogenesis in the absence of PPARgamma. This evidence suggests that PPARgamma is the critical player in the fat differentiation pathway. Dr. Camp and colleagues at Sangamo Biosciences went one step further and identified exac...Findings link disease specific anitbodies to activation of T cells for the first time

Smith, MD and collaborators at Boston University School of Medicine, Boston was published recently in The Journal of Immun...Stool test for colon cancer reported by Kimmel Cancer Center at Johns Hopkins
..., and other scientists, APC mutations initiate the cascade of molecular and cellular errors that eventually result in tumor formation. Though the Hopkins team has always expected this early colon cancer marker was present in cells shed into stool, it required several years of additional research to develop ...High tech movies reveal information transfer within cells
...s. Fusion between membranes requires an ordered cascade of protein activities that define each stage of the process. Employing advanced genetic techniques, the investigators tagged the membrane proteins that catalyze fusion with a green fluorescent protein label. This allowed them to track the proteins ...'Wishful thinking' gene regulates neural development
...," said O'Connor. "So, this is the first signaling cascade that's been identified that must be involved in this coordination." "This paper is just the beginning," said Goodman. "All of the ongoing work points to the discovery of a retrograde signaling mechanism, in which the postsynaptic side of the synapse...Immerge biotherapeutics identifies miniature swine that do not transmit pig retrovirus to humans
