Research: lncRNA affects apoptosis and plays a role in RBC development

A long non-coding RNA (lncRNA) regulates programmed cell death during one of the final stages of red blood cell differentiation, according to Whitehead Institute researchers. This is the first time a lncRNA has been found to play a role in red blood cell development and the first time a lncRNA has been shown to affect programmed cell death.

Scientists discover clues to the pancreatic cysts' possible origins

Scientists at Johns Hopkins have surveyed the DNA in four common types of pancreatic cysts, and have determined that each type bears a distinct pattern of gene mutations. Pancreatic cysts are present in about two percent of U.S. adults, and can, in some cases, require surgical removal and microscopic analysis to determine their type and likelihood of turning cancerous.

Visual cortex cells play a key role in reconstructing 3D shape

As dizzying as it may sound, the impression that we are living in a 3D world is actually a continuous fabrication of our brains. When we look at things, the world gets projected onto the retina and information about the third dimension is lost - a bit like when a 3D object casts a shadow onto a flat, 2D wall. Somehow the brain is able to reconstruct the third dimension from the image, allowing us to experience a convincing 3D world.

CRD to conduct review of safety and effectiveness of BMP-2

The Centre for Reviews and Dissemination (CRD) at the University of York is to conduct a major independent review of the effectiveness and safety of bone morphogenetic protein-2 (BMP-2), a product used in spinal surgeries to promote bone growth.

First realistic 3-D diagram of thalamocortical column in rodent brain

Researchers from the lab of Nobel laureate Bert Sakmann, MD, PhD at the Max Planck Florida Institute (MPFI) are reporting that, using a conceptually new approach and state-of-the-art research tools, they have created the first realistic three-dimensional diagram of a thalamocortical column in the rodent brain.

Intensive maternal care during infancy promotes effect of NPY in brain

Neuropeptide Y (NPY) is the most abundant peptide hormone of the central nervous system. It is involved in various processes including stress management, the development of anxiety behaviour and body weight regulation. A collaborative research group including scientists from the Max Planck Institute for Medical Research in Heidelberg has demonstrated using mice that intensive maternal care during infancy promotes the effect of NPY in the brain.

Researchers sequence entire transcriptome of mouse neural retina

The population of Eric Morrow's seminar "Neurogenetics and Disease" comprises mainly undergraduates who were skipping down the halls of their elementary schools when the first drafts of human genome sequences were published. When Morrow, assistant professor of biology, recently asked the class how to find the mutation behind a disease, a hand shot up in the back of the class to signal the answer: "Sequence the patient's genome."

“Gold standard” stem cells for clinical testing

British researchers claim to have created stem cells of a “gold standard” quality that could lead to a new wave of treatments for degenerative diseases. Taken from human embryos, they could be available to researchers before the end of next year for eventual use in clinical trials, The Daily Telegraph reported Tuesday.

Next generation personal genomic testing now widely available

The era of widely available next generation personal genomic testing has arrived and with it the ability to quickly and relatively affordably learn the sequence of your entire genome. This would include what is referred to as the "exome," your complete set of protein-coding sequences.

New cell formation after arterial injury increases risk of further heart attacks

"After an arterial injury, the inner layer of cells in the artery begins to regrow. In the long term, this usually causes more harm than good", says Maria Gomez.

Relaxin improves poor blood flow and kidney function in a rat model of PKD

After a four-week course of the vasodilator hormone relaxin, kidney function and blood flow immediately improved in lab rats genetically altered to model polycystic kidney disease (PKD), a life-threatening genetic disorder, according to research presented on Dec. 6 at the American Society for Cell Biology Annual Meeting in Denver.

Scientists help uncover evolutionary history of TAS2R38 bitter taste receptor gene

Long the bane of picky eaters everywhere, broccoli's taste is not just a matter of having a cultured palate; some people can easily taste a bitter compound in the vegetable that others have difficulty detecting. Now a team of Penn researchers has helped uncover the evolutionary history of one of the genes responsible for this trait.

Web-based video game players contribute to analysis of DNA sequences

Thousands of video game players have helped significantly advance our understanding of the genetic basis of diseases such as Alzheimer's, diabetes and cancer over the past year. They are the users of a web-based video game developed by Dr. J-r-me Waldispuhl of the McGill School of Computer Science and collaborator Mathieu Blanchette.

Evaluation method supports soy as high-quality protein

The importance of protein in the human body is undeniable. However, the idea of what makes a protein a "quality protein" has not been as easy to determine. A new study from the Journal of Agriculture and Food Chemistry takes a closer look at the criteria for determining the quality of a protein.
