SORT1 pathway holds promise as new target for therapeutic intervention for LDL cholesterol reduction

The true power of genomic research lies in its ability to help scientists understand biological processes, particularly those that - when altered - can lead to disease. This power is demonstrated dramatically in a pair of papers published today in the journal Nature. In the first, a global team of researchers describes 95 different variations across the genome that contribute in different degrees to alterations in blood cholesterol and triglyceride levels in multiple human populations. In the second report, close examination of just one of these common variants not only reveals the involvement of an unexpected genetic pathway in lipid metabolism but also provides a blueprint for using genomic findings to unravel biological connections between lipid levels and coronary heart disease.

Certain human leukemias can be treated by targeting stem-cell microRNAs: Research

Hematopoietic stem cells provide the body with a constant supply of blood cells, including the red blood cells that deliver oxygen and the white blood cells that make up the immune system. Hematopoietic-or blood-stem cells must also make more copies of themselves to ensure that they are present in adequate numbers to provide blood throughout a person's lifetime, which means they need to strike a delicate balance between self-renewal and development into mature blood-cell lineages. Perturb that balance, and the result can be diseases such as leukemia and anemia.

Study links sea sponge genome sequence with first animals and cancer

The sponge, which was not recognized as an animal until the 19th century, is now the simplest and most ancient group of animals to have their genome sequenced. In a paper appearing in the August 5 issue of the journal Nature, a team of researchers led by Daniel Rokhsar of the University of California, Berkeley, and the Department of Energy's Joint Genome Institute (JGI), report the draft genome sequence of the sea sponge Amphimedon queenslandica and several insights the genome gives into the origins of both the first animals and cancer.

Research findings show normal rise and fall in triglycerides

When the circadian rhythm gets thrown off, it could come with an unexpected side effect: high triglycerides. The discovery, based on studies in mice with a "broken clock," helps to explain the normal rise and fall in triglycerides, which happens at about the same time each day, according to researchers who report their findings in the August issue of Cell Metabolism, a Cell Press publication.

Study to understand processes that lead to onset of testicular germ cell cancer

Scientists have developed a model that will enable them to investigate, for the first time, how human testes develop in baby boys while they are in the womb. Until now it has been impossible to study testicular development during pregnancy in humans and this discovery will enable researchers to understand the processes that can lead to the onset of testicular germ cell cancer (TGCC) in young adult life, and how factors, such as common environmental chemicals, might play a role.

People insensitive to quinine's bitter taste may have varied absorption, metabolization capabilities: Study

Some people find quinine to be bitter while others can drink it like water. Now, scientists from the Monell Center and collaborators report that individual differences in how people experience quinine's bitterness are related to underlying differences in their genes.The findings, published online in the journal Human Molecular Genetics, demonstrate that genetic variation in regions of DNA that encode bitter taste receptors predicts a person's perception of bitterness from quinine.

Researchers discover manipulation of microRNA-29a shows potential of novel IBS treatment

A possible cause of irritable bowel syndrome has been traced to a small piece of RNA that blocks a substance protecting the colon membrane, leading to hostile conditions that can produce diarrhea, bloating and chronic abdominal pain.New research shows that this RNA segment sends signals that stop the activity of the gene that produces glutamine, an amino acid. Previous research has linked a shortage of glutamine in the gut with the seepage of toxins and bacteria through the intestinal wall, irritating nerves and creating disease symptoms.
