When genetics gets personal
Just five years after the Human Genome Project announced it had decoded the first human DNA, the era of personal genetics is dawning, bringing with it not just the promise of targeted, personalized medicine and a new level of self-knowledge, but also a host of ethical, legal, and practical issues. A new project out of…

Next-generation tool for visualizing genomic data introduced
Researchers are collecting vast amounts of diverse genomic data with ever-increasing speed, but effective ways to visualize these data in an integrated manner have lagged behind the ability to generate them. To address this growing need, researchers at the Broad Institute of MIT and Harvard have developed the Integrative Genomics Viewer (IGV), a novel and…

‘Speed limit’ found on rate of evolution
Harvard University scientists have identified a virtual “speed limit” on the rate of molecular evolution in organisms, and the magic number appears to be six mutations per genome per generation — a rate of change beyond which species run the strong risk of extinction as their genomes lose stability.

First robust genetic link to height in humans identified
Over a century ago, scientists first proposed that height is a complex trait — one influenced by environmental factors and multiple genes. While subsequent studies revealed that most of the variation in adult height is genetically determined, there has been little success in pinpointing the responsible genes. Some clues have come from rare syndromes of…

Opossum genome shows ‘junk’ DNA source of genetic innovation
A tiny opossum’s genome has shed light on how evolution creates new creatures from old, showing that change primarily comes by finding new ways of turning existing genes on and off. The research, by an international consortium led by the Broad Institute of MIT and Harvard, revises our understanding of genetic evolution. Scientists previously thought…

Despite their heft, many dinosaurs had surprisingly tiny genomes
They might be giants, but many dinosaurs apparently had genomes no larger than those of a modern hummingbird. So say scientists who’ve linked bone cell and genome size among living species and then used that new understanding to gauge the genome sizes of 31 species of extinct dinosaurs and birds, whose bone cells can be…

Practical way to target cancer cell mutations demonstrated
A study led by researchers at Dana-Farber Cancer Institute and Broad Institute of the Massachusetts Institute of Technology and Harvard University provides the first demonstration of a practical method of screening tumors for cancer-related gene abnormalities that might be treated with “targeted” drugs.

Proteasome recognized as nuclear player on gene-transcription team
One of the most common agents in the cytoplasm of the cell, the proteasome, also plays a widespread and critical role in transcription from inside the cell nucleus. Pam Silver, Kathryn Auld, and their colleagues report in the March 17, 2006 Molecular Cell that the proteasome binds and critically regulates the transcription of some of…

Lab moves genomic testing into the clinic
The earliest symptom of the inherited heart condition hypertrophic cardiomyopathy can be sudden death at a tragically young age. Harvard Medical School researchers discovered the first human gene underlying the disorder 15 years ago, but clinical genetic testing to identify those people at risk just became available last year. About the same time, another genetic…

Cancer link to ‘protein promiscuity’ being studied
When found at abnormally high concentrations, two proteins implicated in many human cancers have the potential to spur indiscriminate biochemical signaling inside cells, chemists at Harvard University have found. Their finding may expand scientists’ current understanding of oncogenesis – that cancer arises when an oncoprotein becomes overactive, ramping up the biochemical pathways that it normally…

Double trouble: Cells with duplicate genomes can trigger tumors
So-called “double-value” cells are produced by random errors in cell division that occur with unknown frequency. The generation of these genetically unstable cells appears to be a “pathway for generating a tumor,” says David Pellman, MD, a pediatric oncologist at Dana-Farber and at Children’s Hospital Boston and an associate professor at Harvard Medical School. He…

Surprising variations discovered in human genomes
Researchers from Harvard Medical School and the University of Toronto in Canada looked at 55 healthy, unrelated men and women, and they discovered 255 regions with relatively large gains or losses in their DNA. “We were extraordinarily surprised to see that some people have so much more or less DNA,” says Charles Lee, a geneticist…

Scientists identify hundreds of worm genes that regulate fat storage
Findings by Harvard researchers, published in the Jan. 16, 2003 issue of Nature, represent the first survey of an entire genome for all genes that regulate fat storage.

Formin gene may explain a common cause of female infertility
Harvard Medical School researchers Philip Leder and Benjamin Leader have discovered that oocytes from female mice without the formin gene Fmn2 cannot correctly position the metaphase I DNA-spindle. This produces daughter cells with an abnormal number of chromosomes, the leading cause of female infertility, birth defects, and embryo loss. Genes of the formin family, including…

Harvard researchers complete genomic sequence of deadly malaria parasite
Malaria is the world’s most serious parasitic tropical disease and kills more people than any communicable disease except for tuberculosis. There is more human malaria in Africa today than at any time in history. P.falciparum, the most lethal form of the disease, accounts for the majority of infections, 200 to 300 million, resulting in 1…

The next big thing in mining the genome
About 99.9 percent of the 3.1 billion base pairs in the human genome are the same from person to person. The remaining 0.1 percent of differences comprises more than 10 million common single-letter genetic variations (and many more rare variants) scattered through the genome. By the numbers, a comprehensive search for the multiple genetic contributions…

Mustard shows backbone in its own defense
Over the past few years, accumulated evidence from many scientists suggests that plants, animals, and insects share common elements in their innate skirmishes with potential pathogens.

Human genome sequence yields new tool for microbe-hunting
Microbiologists have traditionally identified pathogens (disease-causing organisms) by growing them in a laboratory dish from a sample of infected tissue. But not all pathogens can be cultured this way. Molecular tools do exist and have been used to identify some new disease organisms, but they have major limitations. But a new microbe-hunting method holds promise…

Scientists using gene chips identify unique form of leukemia
Currently, physicians diagnose and treat a rare form of cancer that strikes infants as a particularly aggressive form of the more common acute lymphoblastic leukemia. The cancer may respond to chemotherapy at first, but it tends to recur fatally. That’s why the prognosis is so much worse than for most types of childhood leukemia, which…

Harvard scientists identify chromosome location of genes associated with long life
