Johns Hopkins researchers find link between cell's energy use and genome health
While studying how a cell keeps its genetic material intact, scientists at Johns Hopkins got busy alternately knocking out two catalysts vital to managing a yeast cell's energy. view more (2006-07-24)
Researchers sequence the basal eukaryote Tetrahymena thermophila
In an effort to improve our understanding of eukaryotic evolution, a team of over 50 researchers led by Jonathan Eisen sequenced the macronuclear genome of the single-celled ciliate Tetrahymena themophila. view more (2006-08-29)
Link unraveled between chromosomal instability and centrosome defects in cancer cells
In a new study, Dana-Farber Cancer Institute scientists disprove a century-old theory about why cancer cells often have too many or too few chromosomes, and show that the actual reason may hold the key to a novel approach to cancer therapy. view more (2009-06-08)
Cold Spring Harbor Protocols features methods for visualizing protein dynamics
This month's release of Cold Spring Harbor Protocols highlights methods that permit scientists to observe protein dynamics in chromosomes and embryos. view more (2008-01-03)
Evolutionary origin of bacterial chromosomes revealed
Researchers have unveiled the evolutionary origin of the different chromosomal architectures found in three species of Agrobacterium. view more (2009-03-27)
Sex hormone signature indicates gender rather than just chromosomes
Help with assigning gender could one day be at hand for intersex individuals whose genital phenotypes and sex chromosomes don't match, thanks to the discovery of a stable sex hormone signature in our cells. view more (2007-10-18)
New telomere discovery could help explain why cancer cells never stop dividing
A group working at the Swiss Institute for Experimental Cancer Research (ISREC) in collaboration with the University of Pavia has discovered that telomeres, the repeated DNA-protein complexes at the end of chromosomes that progressively shorten every time a cell divides, also contain RNA. view more (2007-10-05)
Yeast missing sex genes undergo unexpected sexual reproduction
An emerging form of the pathogenic yeast Candida is able to complete a full sexual cycle in a test tube, even though it's missing the genes for reproduction. view more (2009-05-26)
Let's Stick Together - A Protein Protects Chromosome Bonds
The protein Mnd2 inhibits premature separation of chromosomes during the formation of gametes. The now published discovery of this regulatory function may help to understand the origin of some common congenital chromosome defects. The project of a team of the University of Vienna funded by the Austrian Science Fund (FWF) contributes to the Campus... view more... (2005-03-29)
New Genetic Mechanism For Evolution
A team of researchers from the Universitat Autònoma de Barcelona (UAB) has discovered that transposons, small DNA sequences that travel through the genomes, can silence the genes adjacent to them by inducing a molecule called antisense RNA. This is a new mechanism for evolution that has been unknown until now. The research has been recently... view more... (2004-07-16)
Genetic Imbalance Could Help Predict Colorectal Cancer Prognosis (pp 183, 219)
Results of a study in this week's issue of THE LANCET suggest that an imbalance in specific genetic material on chromosomes 8 and 18 could be a better predictor of colorectal cancer prognosis than conventional histopathological assessment. Chromosome imbalances occur in many cancers and represent important biological properties of tumours.... view more... (2002-01-17)
"Sloppy Genes" Behave Like Their Neighbours: New Findings Reveal That The Regulation Of Gene Expression Is Much Less Strictly Controlled Than Was Previously Thought
The inaugural issue of Journal of Biology features groundbreaking research that challenges the traditional view of how genes are controlled. Our current understanding of gene expression, the fundamental process by which proteins are made from the instructions encoded in DNA, is that the process is tightly controlled so that the correct amount of... view more...

Research shines spotlight on a key player in the dance of chromosomes
Cell division is essential to life, but the mechanism by which emerging daughter cells organize and divvy up their genetic endowments is little understood. In a new study, researchers at the University of Illinois and Columbia University report on how a key motor protein orchestrates chromosome movements at a critical stage of cell division. view more (2008-05-14)
X-Effect: Female Chromosome Confirmed a Prime Driver of Speciation
Researchers at the University of Rochester believe they have just confirmed a controversial theory of evolution. The X chromosome is a strikingly powerful force in the origin of new species. view more (2007-10-18)
Ob1, the first commmon obesity gene was located on chromosome 10
Each family has at least one member whose body mass index (BMI, the ratio of the weight in kg to the surface of the body in m2; normal BMI is below 25) is higher than 40 and at least one other member whose BMI is over 27. 380 genetic markers, covering 23 pairs of chromosomes, were studied in order to find genetic similarities between the obese... view more...

UAB Researchers Discover a New Mechanism Involved in Predisposition to Cancer
A team of researchers at the Universitat Autònoma de Barcelona (UAB) has discovered a new mechanism that accelerates the shortening of telomeres (structures that protect the ends of chromosomes) involved in genetic instability and a predisposition to cancer. The research has been published in the journal Human Molecular Genetics. view more (2002-02-26)
Fruit fly gene research may shed light on human disease processes
Those small fruit flies buzzing around your bananas are more than pests—they may be allies in a fruitful search for clues to human diseases caused when genes malfunction. view more (2007-03-28)
Scientists take a step nearer to creating an artificial egg using a somatic cell
Scientists believe that they are an important step nearer to success in creating an artificial egg from the combination of the nucleus of a somatic cell and an oocyte which has had its DNA-carrying nucleus removed, a conference of international fertility experts heard today (Tuesday 1 July). Dr Peter Nagy, from Reproductive Biology Associates,... view more... (2003-06-28)
Can plant research lead to new insights in cancer research?
Ghent - The development of cancer is a complex process with a number of different causes. The root problem is loss of control in the cell division process. A fundamental biological process, cell division can be studied in many organisms. Researchers from the Flanders Interuniversity Institute for Biotechnology (VIB) connected with Ghent University... view more... (2005-01-10)
Scientists construct a physical map of the Drosophila buzzatii genome
An international team of researchers led by the Universitat Autònoma de Barcelona Professor Alfredo Ruiz, has launched in this month's issue of the journal Genome Research the first detailed physical map of the Drosophila buzzatii chromosomes. view more (2005-06-30)
