Researchers from Huntsman Cancer Institute (HCI) at the University of Utah have discovered that while the genes provided by the father arrive at fertilization pre-programmed to the state needed by the embryo, the genes provided by the mother are in a different state and must be reprogrammed to match. The findings have important implications for both developmental biology and cancer biology. http://phys.org/news287306553.html Biology Thu, 09 May 2013 12:00:21 EST news287306553 A group of scientists at the Instituto Gulbenkian de Ciencia, in Portugal, have uncovered a surprising link between the cell's skeleton and organ size. The team, led by Florence Janody, show in the journal Development, that one of the proteins that regulates the skeleton of the cell also acts to blocks activation of genes that promote cell survival and proliferation. Their findings have implications for cancer research, as they add to the puzzle of understanding how proliferation genes are abnormally activated, often leading to tumours. http://phys.org/news226574176.html Biology Mon, 06 Jun 2011 10:16:32 EST news226574176 Researchers have shown that the Trypanosoma cruzi agent of Chagas Disease (CD) invades host embryo cells and spreads its mitochondrial DNA (kDNA) minicircles into the host's genome. Dr. Antonio Teixeira and associates at the University of Brasília, Brazil, inoculated virulent typanosomes in fertile chicken eggs and documented the heritability and fixation of the kDNA mutations in the chicks and their progeny. The results, published in the open-access journal PLoS Neglected Tropical Diseases on March 29th, show that kDNA-mutated chickens undergo genotype alterations, developing an inflammatory heart condition similar to Chagas disease in humans. http://phys.org/news220639119.html Medicine & Health Tue, 29 Mar 2011 17:39:05 EST news220639119 Bacterial decay was once viewed as fossilization's mortal enemy, but new research suggests bacterial biofilms may have actually helped preserve the fossil record's most vulnerable stuff -- animal embryos and soft tissues. http://phys.org/news146768881.html Biology Mon, 24 Nov 2008 17:08:01 EST news146768881 Researchers at the European Molecular Biology Laboratory (EMBL) have generated a digital zebrafish embryo - the first complete developmental blueprint of a vertebrate. With a newly developed microscope scientists could for the first time track all cells for the first 24 hours in the life of a zebrafish. The data was reconstructed into a three-dimensional, digital representation of the embryo. The study, published in the current online issue of Science, grants many new insights into embryonic development. Movies of the digital embryo and the underlying database of millions of cell positions, divisions and tracks will be made publicly available to provide a novel resource for research and scientific training. http://phys.org/news142777924.html Biology Thu, 09 Oct 2008 13:32:04 EST news142777924 (PhysOrg.com) -- A process that governs embryo implantation in the womb in humans has been identified for the first time. The Oxford University research, published in the journal PNAS, could shed light on what goes wrong when embryos fail to implant in the lining of the womb, a leading cause of infertility. http://phys.org/news142002689.html Medicine & Health Tue, 30 Sep 2008 14:11:29 EST news142002689
