Amino Acid Fingerprints Revealed in New Study

Tempe, AZ (Scicasts) – Some three billion base pairs make up the human genome – the floorplan of life. In 2003, the Human Genome Project announced the successful decryption of this code, a tour de force that continues to supply a stream of insights relevant to human health and disease.

New Epidemiology Model Combines Multiple Genomic Data

Providence, RI (Scicasts) – The difference between merely throwing around buzzwords like "personalized medicine" and "big data" and delivering on their medical promise is in the details of developing methods for analyzing and interpreting genomic data.

Congenital Heart Disease Gene Found

Hinxton, UK (Scicasts) – Researchers have explored the role of a master gene that controls the functioning of other genes involved in heart development. Variations in this gene - NR2F2 - are responsible for the development of severe forms of congenital heart disease.

New Technique for Identifying Gene-Enhancers

Berkeley, CA (Scicasts) – An international team led by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) has developed a new technique for identifying gene enhancers - sequences of DNA that act to amplify the expression of a specific gene – in the genomes of humans and other mammals.

APC and Colon Cancer: Location Matters

Kansas City, KS (Scicasts) – Proteins, like people, can be complex and mysterious – at least to the scientists studying them. Some two decades after discovering adenomatous polyposis coli (APC), researchers are still puzzling out this particular protein’s secrets.

Bacterial Reporters That Get the Scoop

Cambridge, MA (Scicasts) – It's a jungle in there. In the tightly woven ecosystem of the human gut, trillions of bacteria compete with each other on a daily basis while they sense and react to signals from the immune system, ingested food, and other bacteria.

Big Data Tackles Tiny Molecular Machines

Houston, TX (Scicasts) – Open, feed, cut. Such is the humdrum life of a motor molecule, the subject of new research at Rice University, that eats and excretes damaged proteins and turns them into harmless peptides for disposal.

An Equation to Describe the Competition Between Genes

Pasadena, CA (Scicasts) – In biology, scientists typically conduct experiments first, and then develop mathematical or computer models afterward to show how the collected data fit with theory. In his work, Rob Phillips flips that practice on its head.

IRX3 Is Likely the “Fat Gene”

Chicago, IL (Scicasts) – Mutations within the gene FTO have been implicated as the strongest genetic determinant of obesity risk in humans, but the mechanism behind this link remained unknown.

Finding the Switch: Researchers Create Roadmap for Gene Expression

Raleigh, NC (Scicasts) – In a new study, researchers from North Carolina State University, UNC-Chapel Hill and other institutions have taken the first steps toward creating a roadmap that may help scientists narrow down the genetic cause of numerous diseases.

Study Shows Leukaemia Caused by Chromosome Catastrophe

Hinxton, UK (Scicasts) – Researchers have found that people born with a rare abnormality of their chromosomes have a 2,700-fold increased risk of a rare childhood leukaemia. In this abnormality, two specific chromosomes are fused together but become prone to catastrophic shattering.

Taking Immune Cells for a Test Drive

Cambridge, MA (Scicasts) – You’re on a crowded subway car and someone nearby sneezes. Influenza viruses shed by your fellow rider are expelled in droplets of saliva that land on you and the person next to you. Two days later, you begin suffering from the classic flu symptoms of fever, aches, and runny nose, while the lucky rider next to you somehow dodges the infectious bullet.

Cancer Therapy May Be Too Targeted

Hinxton, UK (Scicasts) – Researchers have identified two novel cancer genes that are associated with the development of a rare, highly aggressive, cancer of blood vessels. These genes may now act as markers for future treatments and explain why narrowly targeted therapies that are directed at just one target fail.

A Novel Mechanism for Fast Regulation of Gene Expression

St. Louis, MO (Scicasts) – Our genome, we are taught, operates by sending instructions for the manufacture of proteins from DNA in the nucleus of the cell to the protein-synthesizing machinery in the cytoplasm. These instructions are conveyed by a type of molecule called messenger RNA (mRNA). [Videos]

Newly Identified Small-RNA Pathway Defends Genome Against the Enemy Within

Cold Spring Harbor, NY (Scicasts) – Reproductive cells, such as an egg and sperm, join to form stem cells that can mature into any tissue type. But how do reproductive cells arise? We humans are born with all of the reproductive cells that we will ever produce. But in plants things are very different.

Study Proposes New Ovarian Cancer Targets

Providence, RI (Scicasts) – In the complex genomic and molecular conspiracy that gives rise to ovarian cancer, what if researchers have been missing a whole set of suspects because they've been hiding in plain sight?
