Genomic imprinting in disruptive spermatogenesis (p 1700)
Low sperm counts could be associated with genomic imprinting disease and could carry a raised risk of transmitting imprinting defects following assisted reproductive technologies, claim researchers in this week's issue of THE LANCET. Genomic imprinting is a gene regulatory mechanism based on differential methylation, whereby only one of two... view more... (2004-05-19)
The evolutionary foundation of genomic imprinting in lower vertebrates
A Chinese scientist group working in College of Life Science, Zhejiang University, has shown that, as mammalian Igf2 CpG island, goldfish Igf2 CpG island has a parental differentially methylated region (DMR). view more (2009-05-18)
Non-coding RNAs help silence the mammalian transcription
Dr. Shirley Tilghman and colleagues (Princeton University) lend new insight into the mechanism of genomic imprinting, demonstrating a necessary role for a non-coding RNA transcript in the silencing of an imprinted gene cluster in mice. view more (2006-05-15)
Evolution of genomic imprinting
How we come to express the genes of one parent over the other is now better understood through studying the platypus and marsupial wallaby - and it doesn't seem to have originated in association with sex chromosomes. view more (2007-09-07)
Link between assisted reproduction techniques and genetic disruption
Evidence that assisted reproduction techniques may carry a risk of genetic 'imprinting disorders' in the resulting babies, emerges in a study published in the Journal of Medical Genetics. To assess the likely risk of genetic disruption, geneticists from the University of Birmingham and the West Midlands Genetics Service assessed the birth... view more... (2003-01-14)
High protein diet may be bad for women trying to conceive
A moderately high protein diet could reduce a woman's chances of becoming pregnant, according to new research presented at the 20th annual conference of the European Society of Human Reproduction and Embryology today on Monday 28 June. Researchers from the USA have found that a diet containing 25% protein disrupted the normal genetic imprinting... view more... (2004-06-28)
Duke scientists map imprinted genes in human genome
Scientists at Duke University have created the first map of imprinted genes throughout the human genome, and they say a modern-day Rosetta stone - a form of artificial intelligence called machine learning - was the key to their success. view more (2007-11-30)
Molds for Molecules
Molecular imprints in polymers as reaction vessels for pharmaceuticals research Materials with the tiniest of cavities, which can take up other molecules as "guests", play a meaningful role in science and technology. A particularly interesting process for the synthesis of materials with precisely fitted cavities is known as molecular imprinting.... view more... (2002-11-28)
How IVF could be causing genetic errors in embryos
The conditions in which embryos are cultured in the laboratory during in vitro fertilisation could be causing genetic errors that are associated with certain developmental syndromes and other abnormalities in growth and development, such as low birth weight. view more (2006-06-19)
First evidence that genetic imprinting occurs at earliest stage in test tube-matured eggs
Madrid, Spain: New research indicates that attempts to mature ovarian follicles in the laboratory may hit a stumbling block unless better 'growing' conditions can be identified. A French team[1] of fertility experts has revealed for the first time that maternal genetic imprinting errors can occur at the very earliest stages of egg follicle... view more... (2003-06-27)
Living fossil roams the seas
Fossil' fish coelacanth, first dragged up along the coast of South Africa in 1938, having been considered extinct for 65 million years. Because of its close resemblance to land animals, it has attracted attention to the subject of a 'missing link' between tetrapods and humans. view more (2005-07-13)
Study examines genetic factors associated with head and neck cancer
Preliminary research indicates that several specific genetic alterations are associated with the development of smoking-related head and neck skin cancers. view more (2007-01-10)
New hope for regenerative medicine
In the February 15th issue of G&D, Dr. K. John McLaughlin and colleagues report on their success in using uniparental embryonic stem cells to replace blood stem cells in mice. view more (2007-02-15)
Bioportfolio: Life-long persistence of erythrovirus DNA genomes in human tissue
The researchers at the University of Helsinki, Finland, and University Hospital of Bonn, Germany, have coined the novel term "Bioportfolio" to describe viral genomic material remaining in the human body after infection. view more (2006-04-26)
New tool cracks genomic code quicker than ever
US and Australian scientists have pioneered a new hybrid method for genomic sequencing that is faster and cheaper than state of the art technologies. view more (2006-07-11)
Genostar demonstrates its bioinformatics platform for exploratory genomics
Paris, May 21 2002 - The Genostar consortium today announces the launch of its Genostar platform for exploratory genomics, the result of two and a half years research carried out by a team of more than 20 genomics and bioinformatics scientists and developers. Exploratory genomics involves the study of the structure and function of genes and... view more... (2002-05-22)
Specific genetic cause of fetal alcohol-related developmental disorders found
Alcohol consumption by pregnant women hinders brain development in their children by interfering with the genetic processes that control thyroid hormone levels in the fetal brain, a new animal study found. view more (2009-06-11)
Media Invitation: British Neuroscience Association National Meeting
The British Neuroscience Association (BNA) is about to host its 17th National Meeting in Harrogate (13-16 April) and is attracting more delegates than ever before. With seven plenary lectures, 20 symposia and over 40 poster sessions, this will be quite a neuroscience festival for the UK. It will be supported by a full scale exhibition and numerous... view more... (2003-04-03)
New species from old data - By searching genome sequences of several Drosophila species researchers have identified new bacterial species that live inside fruit flies.
Researchers have discovered three previously unknown species of a bacterium by scanning a publicly available data bank, reveals a study published today in the journal Genome Biology. The finding highlights the value of making unanalysed data from large-scale genome sequencing projects openly available online. view more (2005-02-18)
Not just humans benefit from animal biotechnology
Laboratory animals are the source of major discoveries and breakthroughs in biology, not just in tackling disease but also unravelling fundamental molecular processes. Delegates at a recent research conference organised by the European Science Foundation (ESF) and Wellcome Trust heard how technology capable of analysing animal genes across the... view more...
