A new view of our chromosomes reveals a complex picture Chromosomes – the 46 tightly-wrapped packages of genetic material in our cells – are iconically depicted as X-shaped formations. However, those neat X’s only appear when a cell is about to divide and the entire contents of its genome duplicated. Until now researchers have not been able to get a good picture of the way that our DNA – some two meters of strands all told – is neatly bundled into the nucleus while enabling...

Two Y Genes Can Replace Entire Y Chromosome For Assisted Reproduction In Mice
2013-11-21 15:33:20

University of Hawaii at Manoa The Y chromosome is a symbol of maleness, present only in males and encoding genes important for male reproduction. But live mouse offspring can be generated with assisted reproduction using germ cells from males with the Y chromosome contribution limited to only two genes: the testis determinant factor Sry and the spermatogonial proliferation factor Eif2s3y. "Does this mean that the Y chromosome (or most of it) is no longer needed? Yes, given our current...

Genealogical and medical records of males in Utah's multi-generational families were analyzed An analysis of the genealogical and medical records of males in Utah's multi-generational families strongly supports the case that inherited variations in the Y chromosome, the male sex chromosome, play a role in the development of prostate cancer, according to a study presented today (Friday, Oct. 25) at the American Society of Human Genetics 2013 meeting in Boston. The study identified...

Genome-wide changes result from silencing extra chromosome, scientists report at ASHG 2013 The first evidence that the underlying genetic defect responsible for trisomy 21, also known as Down syndrome, can be suppressed in laboratory cultures of patient-derived stem cells was presented today (Oct. 22) at the American Society of Human Genetics 2013 annual meeting in Boston. People with Down syndrome are born with an extra chromosome 21, which results in a variety of physical and...

Every case of cancer originates from changes in a person's genetic material (mutations). These usually occur as "somatic mutations" in individual cells during an individual's lifetime, rather than being inherited from a person's parents. "Over time, the original damaged cell accumulates additional mutations, and it is still largely unknown why," says Prof. Roland Eils, who leads bioinformatics departments both at DKFZ and Heidelberg University. By studying when and where mutations occur...

First 3D Pictures Of Chromosome Structure Revealed
2013-09-25 15:40:45

Biotechnology and Biological Sciences Research Council A new method for visualizing chromosomes is painting a truer picture of their shape, which is rarely like the X-shaped blob of DNA most of us are familiar with. Scientists at the BBSRC-funded Babraham Institute, working with the University of Cambridge and the Weizmann Institute, have produced beautiful 3D models that more accurately show their complex shape and the way DNA within them folds up. The X-shape, often used to...

Discovery provides target to potentially halt the process, prevent cancers Biologists reported today in Nature that they have identified two pathways through which chromosomes are rearranged in mammalian cells. These types of changes are associated with some cancers and inherited disorders in people. "Our finding provides a target to prevent these rearrangements, so we could conceivably prevent cancer in some high-risk people," said senior author Edward P. (Paul) Hasty, D.V.M., of the...


Word of the Day
cruet
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
