University of Leicester-led research finds Y chromosome link for coronary artery disease A common heart disease which kills thousands each year may be passed genetically from father to son, according to a study led by the University of Leicester. A paper published in medical journal The Lancet on THURSDAY FEB 9 shows that the Y chromosome, a part of DNA present only in men, plays a role in the inheritance of coronary artery disease (CAD). The study, called Inheritance of coronary...

X Factor Determined Chimpanzee Development

Genetic mutations that boost an individual´s adaptability have greater chances of getting through to X chromosomes — at least in chimpanzees, according to new Danish research. One of the most important questions for evolution researchers is how a species develops and adapts during the course of time. An analysis of the genes of twelve chimpanzees has now demonstrated that the chimpanzee X chromosome plays a very special role in the animal´s development. The analysis was...

Frogs Use Calls To Find Mates With Matching Chromosomes

Tree frogs that look similar hear chromosome difference in calls; offers new insight to frog evolution When it comes to love songs, female tree frogs are pretty picky. According to a new study from the University of Missouri, certain female tree frogs may be remarkably attuned to the songs of mates who share the same number of chromosomes as they do. The discovery offers insight into how new frog species may have evolved. Carl Gerhardt, Curators Professor of Biological Sciences in the...

Geneticists at Emory University School of Medicine have demonstrated a method that enables the routine amplification of all the genes on the X chromosome. The technology allows the rapid and highly accurate sequencing and identification of novel genetic variants affecting X chromosome genes. The method, developed in cooperation with RainDance Technologies, is described in the Oct. 2011 issue of Genomics. Senior author Michael Zwick, PhD, assistant professor of human genetics at Emory...

New research presented today at the European Society for Pediatric Endocrinology meeting has found a genetic region, which may control testicle development in the fetus. Men have XY sex chromosomes, and the development of testes is thought to occur after upregulation of the testicular SOX9 gene pathway, in the presence of factor SRY on the Y chromosome. However, the mechanism by which this testicular SOX9 upregulation occurs has so far been unclear. In this study, Dr Jacqueline Hewitt...

Research Disputes Established Theory on Chromosome Activity Fruit flies have been indispensible to our understanding of genetics and biological processes in all animals, including humans. Yet, despite being one of the most studied of animals, scientists are still finding the fruit fly to be capable of surprises, as evidenced by new research at the University of Rochester. The latest revelation has to do with the activity of the X chromosome in male fruit flies. It was widely accepted...

Researchers from Trinity College Dublin have uncovered the evolutionary mechanisms that have caused increases or decreases in the numbers of chromosomes in a group of yeast species during the last 100-150 million years. The study, to be published on July 21st in the open-access journal PLoS Genetics, offers an unprecedented view of chromosome complement (chromosome number) changes in a large group of related species. A few specific cases of chromosome number changes have been studied in...

NEW HAVEN, Conn., March 3, 2011 /PRNewswire/ -- The launch of a new, non-invasive test for the identification of Turner syndrome (TS) was announced today by JS Genetics. The test, XCAT-TS, is a simple cheek swab that identifies girls with Turner syndrome. Until now, Turner syndrome could only be diagnosed with a Karyotype, an invasive test that requires blood from the patient. The results of the XCAT-TS validation study were published in the February 2011 issue of Journal of Clinical...

The genes that make up the human genome were mapped by HUGO, the Human Genome Organization, and published in 2001. Now the project is expanding into the HUPO, the Human Proteome Organization. Within the framework of this organization, many hundreds of researchers around the world will work together to identify the proteins that the different genes give rise to in the human body. "The 'proteome', the set of all human proteins, is significantly more complicated than the genome. There are over...

University of Adelaide researchers are a step closer to unraveling the mysteries of human sexual development, following genetic studies that show male mice can be created without a Y chromosome "“ through the activation of an ancient brain gene. Males usually have one Y chromosome and one X chromosome, while females have two X chromosomes. A single gene on the Y, called SRY, triggers testes development in the early embryo, and once these begin to form, the rest of the embryo also...


Word of the Day
caparison
  • A cloth or covering, more or less ornamented, laid over the saddle or furniture of a horse, especially of a sumpter-horse or horse of state.
  • Clothing, especially sumptuous clothing; equipment; outfit.
  • To cover with a caparison, as a horse.
  • To dress sumptuously; adorn with rich dress.
This word ultimately comes from the Medieval Latin 'cappa,' cloak.
