Researchers have built the first comprehensive manually-generated, literature-based, database of genetic and protein interactions. The database, which doubles the amount of information available on interaction networks in the yeast Saccharomyces cerevisiae, will be a useful resource for both the yeast and the systems biology community. In a study published today in the open access journal Journal of Biology, researchers manually curated the entire literature for genetic and physical protein i
In a new study published in the latest issue of Ethology researchers show that female songbirds can alter the size of eggs and possibly the sex of their chicks according to how they perceive their mate’s quality.
The researchers played back attractive (“sexy”) songs and less attractive control songs of male canaries to female domesticated canaries. When the females started egg-laying they varied the size of their eggs in the nest according to the attractiveness of the male’s
Researchers at Rensselaer Polytechnic Institute, the Marine Biological Laboratory (MBL) in Woods Hole and Louisiana State University (LSU) Health Sciences Center have discovered the presence of the genetic material RNA in the centrosome, the organizing structure inside each cell that assures proper cell division.
The findings, detailed June 5 in the online early edition of the journal Proceedings of the National Academy of Sciences, present evidence that individual centrosomes within a
Surf clam egg study may change thinking about centrosomes
Despite more than a century of study, scientists know relatively little about the inner workings of centrosomes–organelles essential to cell division in humans and animals. Now new research by scientists studying surf clams at the MBL (Marine Biological Laboratory) shows that centrosomes may contain ribonucleic acid (RNA), the molecule that translates genes into proteins.
The research, published June 5 in
A new strategy for getting anti-cancer drugs to kill cancer cells, without causing serious harm to normal cells in the body, is reported in the current [June] issue of ACS Chemical Biology, a monthly peer-reviewed journal of the American Chemical Society.
The approach, tested in laboratory experiments with several existing anti-cancer drugs, could offer substantial benefits for cancer patients, according to Jeffrey P. Krise, Ph.D. Krise led a group of pharmaceutical and medicina
‘LEGO-Like’ Building Blocks to Halt Cell Growth Wins Kaye Prize for Hebrew University Ph.D. Student
A method for delivery of drugs to targeted cells through the design of specific molecular structures called SIB (Small Integrated Building Blocks) has won a prestigious scientific prize for a Ph.D. student in organic chemistry at the Hebrew University of Jerusalem.
Jerusalemite Nir Qvit, 34, will be one of those receiving the Kaye Innovation Award on June 13, during the
Liquorice compounds could be a key component for cheaper, more effective liver cancer treatment, reports Lisa Richards in Chemistry & Industry magazine.
Liver cancer affects over 2,800 people in the UK each year, of which nearly 2,700 die, according to Cancer Research UK. Surgery is the best option, but is unsuitable for most patients, and liver tumours are very resistant to chemotherapy.
Studies in mice by Zhi Yuan and his team at Nankai University, China, revealed tha
Some of the cancer cells’ closest allies have been unveiled. Fortunately, the researchers from BRIC (Biotech Research & Innovation Centre) at University of Copenhagen have also discovered how to beat them. And that could prove to be the first step towards a new remedy for cancer.
The BRIC research team has discovered a family of enzymes that prevents cancer cells to age like normal cells. The good news is, that the researchers have developed small molecules that can impede the enzyme acti
Thanks to a recent study on the genetic factors that promote muscular hypertrophy among Texel sheep, Prof. Michel Georges’ team at the University of Liège has discovered a new kind of mutation that could be at the origin of many phenotypes in various species, among which humans, including genetic predispositions to certain hereditary diseases. This discovery is of significant interest to the international scientific community. The results are published in this week’s edition of the American jo
Study finds that the endoglin protein acts together with sFlt1 to rapidly escalate disease
Building on their earlier discovery which found that elevated levels of the sFlt1 placental protein leads to the onset of preeclampsia, researchers at Beth Israel Deaconess Medical Center (BIDMC), in collaboration with a research team from The Hospital for Sick Children, Toronto, have identified a second protein which, in combination with sFlt1, escalates preeclampsia to a severe – and
University of Pittsburgh School of Medicine researchers have successfully used gene therapy to accelerate muscle regeneration in experimental animals with muscle damage, suggesting this technique may be a novel and effective approach for improving skeletal muscle healing, particularly for serious sports-related injuries. These findings are being presented at the American Society of Gene Therapy annual meeting in Baltimore, May 31 to June 4.
Skeletal muscle injuries are the most common i
By recovering and sequencing intact DNA from an especially ancient Neandertal specimen, researchers have found evidence suggesting that the genetic diversity among Neandertals was higher than previously thought. The findings also suggest that genetic diversity may have been higher in earlier Neandertal periods relative to later periods that approached the arrival of humans in Europe. Changes in genetic diversity over time are thought to reflect population events, such as low-population bottlenec
