Scientists analyze chromosomes 2 and 4

...ed a segmental duplication. "These data raise the possibility of a new tool for studying genome evolution. We may be able to find other chromosomes that have disappeared over the course of time by searching other mammals' DNA for similar patterns of duplication," said Richard K. Wilson, Ph.D., director of the W...

Young Blood Revives Aging Muscles, Stanford Researchers Find

...lls in muscle and liver. "We need to consider the possibility that the niche in which stem cells sit is as important in terms of stem cell aging as the cells themselves," said Rando, who is also an investigator at the Veterans Affairs Palo Alto Health Care System. It could be the chemical soup surrounding the c...

Embryonic Stem Cells Treated With Growth Factor Reverse Hemophilia In Mice: UNC Researchers

...ture applications, not only as a novel therapeutic possibility for hemophilia but also for other genetic or acquired diseases of the liver, said senior co-author Dr. Jeffery A. Frelinger, Kenan professor and chairman of microbiology and immunology. "The data published in this study shows that embryonic stem cel...

Pair of cancer genes found to drive both cell migration and division

... a dividing cell's halves to separate, raising the possibility that interfering with them could be helpful in stopping the uncontrolled cell division found in cancers. Mutations in the genes, called PTEN and PI3K, already had been found in over half of all human cancers. "In cancer, you sometimes see cells fail...

...ss treatment options and essentially ruled out the possibility of a vaccine. MBL trypanosome experts in Robert Sabatini's lab hypothesize that base J (beta-D-glucosylhydroxymethyluracil) may play an important role in the gene silencing process behind antigenic variation. With the goal of learning how the organi...

Researchers Identify Cause of Early Bird Sleep Disorder

...could be purely coincidental, but a more important possibility is that these are part of the same syndrome." So far, however, "we haven't even looked at that yet." He estimated that a very small number (about .3 percent) of the human population seems to have this "circadian clock" shift. And in earlier research...

Antiretroviral Therapy May Prevent HIV Transmission From Breastfeeding Mothers To Infants

...e infant. The high drug concentrations raised the possibility of some risks, as well as benefits, however. Such levels may be high enough to cause adverse effects associated with the drugs, such as rash, neutropenia, and anemia, and to lead to the emergence of drug-resistant virus. For the second study, the re...

High-powered gene profiles provide clues to genes involved in common form of lung cancer

...kin cells to reproduce. The new finding raises the possibility that adenocarcinoma and squamous cell carcinoma arise from an error in the same cell type and are driven to malignancy by similar genetic routes, the study authors say. Finally, the researchers compared their data for NSCLC with similar data for pan...

Circulating stem cells play small role in lung repair

The possibility that the presence of male gender pneumocytes in female lungs might result from an earlier pregnancy with a male fetus cannot be ruled out, Zander said. However, the association between the number of those cells found in the lung tissue with damage fr...

Human embryonic stem cells have the potential to develop into eggs and sperm in the laboratory

...ally become eggs or sperm. Their work opens up the possibility that eggs and sperm could be grown from stem cells and used for assisted reproduction, therapeutic cloning and the creation of more stem cells for further research and for the improved treatments for patients suffering from a range of diseases.

Researchers feed tiny pills of RNA to planarians to identify genes essential for regeneration

...id. "It's a huge step forward for us and opens the possibility of systematic molecular studies to find the genetic cause of regenerative processes in animals." Silencing planarian genes may also help in studying human disease. Thirty-eight of the genes Sánchez Alvarado and his team silenced are related to human...

New protein vital for immune response is found in surprise location

"These results raise the possibility that variations in the expression levels of MAVS may endow different individuals with varying ability to fight off viral diseases," said Dr. Chen, who also is an investigator with the Howard Hughes Medical Institute. "Viruses have evolved along with ...

Sandia completes depleted uranium study

...or these individuals, DU-related risks include the possibility of temporary kidney damage and about a 1 percent chance of fatal cancer. Several earlier studies were carried out by the U.S. Department of Defense, by University Professors Fetter (University of Maryland) and von Hippel (Princeton), and by an Army ...

Overbearing colored light may reveal a second mechanism by which birds interpret magnetic signals

...hat magnetoreception was light dependent, and this possibility was subsequently given support by work from the Wiltschko team showing that the orientation of European robins, a night-migrating species, was influenced by the intensity of light in the blue-green spectrum. In the present study, the Ritz and Wilts...

New lead reported in tumor angiogenesis

... said these early data also suggest the intriguing possibility of directing growth-inhibiting drugs at the normal blood vessel cells to stop angiogenesis. "It's well established that tumor cells can become resistant to chemotherapy," said Dr. Wang. "For endothelial cells, which are the cells that line the walls ...

Carnegie Mellon University research reveals how cells process large genes

...ic advantages for large introns," Lopez said. "One possibility is that recursive splicing prevents the generation of long RNA transcripts that could form structures that interfere with correct processing into mRNA. Another is that recursive splicing might help stimulate transcription through long introns by prom...
