Gene found to be key in etiology of cleft palate

The discovery that adult skin cells can be 'reprogrammed' to behave like stem cells has been a major scientific boon, providing a way to tap the potential of embryonic stem cells without the associated ethical quandaries. Now, in a study appearing online in JBC, researchers have created a line of such reprogrammed stem cells from adult pigs.

RNA Silencing Sheds Light on the RNA World
RNA silencing — also known as RNA interference — is an intriguing phenomenon in which short, double-stranded RNA “triggers” can prevent the expression of specific genes. First discovered in plants, RNA interference is now recognized as a widespread, if not ubiquitous, phenomenon, and it is causing great excitement as an experimental technique for selectively blocking gene expression.

Reinventing Human genome
Geneticists have generally assumed that your string of DNA 'letters' is 99.9% identical to that of your neighbour's, with differences in the odd individual letter. These differences make each person genetically unique — influencing everything from appearance and personality to susceptibility to disease. But hold on, say the authors of a new study published in Nature. They have identified surprisingly large chunks of the genome that can differ dramatically from one person to the next.

Genetic mutation identified as cause of cranio-lenticulo-sutural dysplasia
A research team led by a UC Davis Childrens Hospital scientist has identified a genetic mutation as the cause of a congenital craniofacial birth defect called cranio-lenticulo-sutural dysplasia. The mutation closes off a pathway that is vital to the transport of cellular proteins and, in doing so, significantly alters normal growth patterns of skeletal and connective tissue. The research finding, which appears in the October issue of Nature Genetics , is independently confirmed in a Vanderbilt University Medical Center study published in the same issue

Chance Fluctuations in mRNA Output in Mammalian Cells
In the drama of cell biology, both genetics and environment write the script, and chance throws in the twists of plot. In general, most cells live relatively predictable lives: divide, differentiate, and die. Yet chance leaves its imprint even in ordinary cells. For instance, bacterial or yeast cells in culture are known to produce widely different amounts of certain proteins, even when they are genetically identical. Scientists attribute such cell-to-cell variations to chance fluctuations in the cellsâ ability to make these proteins. They also speculate that such fluctuations may benefit the cells in their struggle to adapt and survive.

Transposon Silencing Keeps Jumping Genes in Their Place
Nearly a century ago, two geneticists described ârogueâ pea plants with an unorthodox pattern of inheritance. William Bateson and Caroline Pellew found that crossing inferior rogues with normal plants always produced rogue offspring, suggesting that the rogue appearance was a dominant trait. The real surprise came when rogue progeny were crossed back to normal plants. Following the principles of Mendelian inheritance, these crosses should have produced a mix of normal and rogue plants, but they produced only rogue plants. The phenomenon, later dubbed âparamutation,â allowed the rogues to break the rules by acting âepigeneticallyââinducing heritable changes in gene expression without DNA mutations. In one-sided interactions between gene pairs, or alleles, only âparamutagenicâ alleles can attenuate, and eventually silence, the expression of âparamutableâ alleles.

New research published in the August issue of the Journal of Cell Biology explains for the first time why congenital heart defects so often occur with limb deformities. In their research into the molecular mechanisms that control embryonic limb and heart development, Northwestern University researcher Hans-Georg Simon and his laboratory group recently identified a new protein, LMP4, which binds and regulates activity of the Tbx4 and Tbx5 transcription factors. Tbx5 and Tbx4 proteins play a key role in limb and heart formation in virtually all vertebrates, from fish to birds to mice to humans.

Emory University scientists have identified and created a map of more than 400,000 insertions and deletions (INDELs) in the human genome that signal a little-explored type of genetic difference among individuals. INDELS are an alternative form of natural genetic variation that differs from the much-studied single nucleotide polymorphisms (SNPs). Both types of variation are likely to have a major impact on humans, including their health and susceptibility to disease.

Gene amplification plays an important role in causing cancers via activation of oncogenes. If scientists can determine the rules as to which segments of genetic material become amplified and how, oncologists and drug researchers may be able to interrupt that process and prevent the formation and growth of some tumors. Using yeast as a model organism, researchers at the Georgia Institute of Technology have discovered that the location of a hairpin-capped break relative to the end of the chromosome will determine the fate of the amplification event.
