Findings call for a rethinking of cancer genetics Johns Hopkins researchers report that the deletion of any single gene in yeast cells puts pressure on the organism’s genome to compensate, leading to a mutation in another gene. Their discovery, which is likely applicable to human genetics because of the way DNA is conserved across species, could have significant consequences for the way genetic analysis is done in cancer and other areas of research, they say. Summarized in a report...

A study led by researchers at the University of California, San Diego School of Medicine shines a new light on molecular tools our cells use to govern regulated gene expression. The study was published on line in advance of print November 10 in the journal Nature Structural and Molecular Biology. "We uncovered a novel mechanism that allows proteins that direct pre-mRNA splicing – RNA-binding proteins – to induce a regulatory effect from greater distances than was thought possible,"...

Gladstone-led study reveals new insight into origins of our species What does it mean to be human? According to scientists the key lies, ultimately, in the billions of lines of genetic code that comprise the human genome. The problem, however, has been deciphering that code. But now, researchers at the Gladstone Institutes have discovered how the activation of specific stretches of DNA control the development of uniquely human characteristics—and tell an intriguing story about the...

Scientists at SISSA investigate a mechanism that switches genes on and off A cell is a complex environment in which substances (metabolites) must maintain a correct state of equilibrium, which may vary depending on specific needs. Cells can maintain the proper concentrations of metabolites by regulating gene protein encoding through specific "switches", called riboswitches, which are able to block or activate protein synthesis. The precise mechanism by which these short strands of RNA...

A rudimentary form of life that is found in some of the harshest environments on earth is able to sidestep normal replication processes and reproduce by the back door, researchers at The University of Nottingham have found. The study, published in the journal Nature, centers on Haloferax volcanii — part of a family of single-celled organisms called archaea that until recently were thought to be a type of bacteria. The findings, led by scientists from the University's School of Life...

On October 8th, Hun School Advanced Placement Biology students began working on an extended research project with Rutgers University’s Waksman Student Scholars Program. Conducting original genetic research, students will have hands-on experience in isolating, sequencing, and analyzing genes from the species Landoltia punctata. Princeton, NJ (PRWEB) November 01, 2013 On October 8th, Hun School Advanced Placement Biology students began working on an extended research project with Rutgers...

Deleting One Gene In Fungus Reveals New Compounds With Antibiotic Potential
2013-11-01 08:42:09

Oregon State University Researchers at Oregon State University have discovered that one gene in a common fungus acts as a master regulator, and deleting it has opened access to a wealth of new compounds that have never before been studied – with the potential to identify new antibiotics. The finding was announced today in the journal PLOS Genetics, in research supported by the National Institutes of Health and the American Cancer Society. Scientists succeeded in flipping a genetic...

Kiwi Genome Reveals A Few Surprises
2013-10-27 05:36:19

redOrbit Staff & Wire Reports - Your Universe Online Scientists working to sequence the genome of the kiwifruit have revealed that the berry has recently undergone a pair of whole-genome duplication events, according to new research published earlier this month in the journal Nature Communications. Zhangjun Fei, an associate professor at the Boyce Thompson Institute at Cornell University, and his colleagues also discovered that there were many similarities between the kiwi’s more...

Knockout Mouse
2013-10-02 11:52:01

A Knockout Mouse is a genetically engineered mouse in which researchers have inactivated, or “knocked out,” an existing gene by replacing it or disrupting it with an artificial piece of DNA. The loss of gene activity frequently causes changes in a mouse’s phenotype, which includes appearance, behavior, or other apparent and biochemical characteristics. Knockout mice are significant animal models for studying the role of genes which have been sequenced but whose functions haven’t...
