State police explained why DNA swabs are sometimes taken from the victims of crimes. That comes after a Prairieville woman was upset her husband was swabbed after his car was broken into. Authorities say taking DNA samples of victims of a crime scene can protect them.

Forensic scientist said a victim's genetic information could be all over the crime scene.

"We need a sample from those individuals so that we can remove the profile we get from that and try to deduce what the unknown perpetrator profile is," said Joanie Brocato DNA manager at the Louisiana State Police Crime Lab.

By taking the victim's DNA, police can exclude it, and try to figure out which DNA belongs to the thief. That prevents a victim's genetic information from going into a database called Codis.

"The database here in Louisiana has approximately 500,000 samples of DNA profiles that belong to arrestees, convicted offenders, and other samples of other crime scenes," said Brocato.

She said a victim's genetic information, is kept in a secure location in the lab. If a case does develop those samples can be critical pieces of evidence. She also said DNA sampling has changed how fast an investigation can go, and assures law abiding citizens they should not be afraid.

'Genome Hacker' Builds Family Trees With Millions of Branches

Posted: at 6:42 pm

Megan Garber for The Atlantic 2013-11-01 16:02:00 UTC

There may be a new record for the largest family tree ever assembled. It dates back to the 15th century. It is comprised of 13 million individuals. And it is only one part of an even larger collection of genomic information: a collection compiled by the computational biologist Yaniv Erlich and stored not in albums or on walls, but in machines.

Presented at the annual meeting American Society of Human Genetics in Boston, and discussed in the journal Nature, the mega-repository could offer a new way for researchers to analyze the relationships between human genotypes and phenotypes between, essentially, nature and nurture.

In the past, such expansively branched informational trees would have been painstaking to cultivate. We have documentation, sure, of family relationships and the traits associated with them church records, hospital logs, that kind of thing but gathering those documents for analysis took time. Assembling genealogical data for even just a few thousand individuals, Erlich noted during his ASHG presentation, could take years.

So here's where the hacking comes in: Erlich and his team, rather than gathering those data themselves, went to a more streamlined source: geni.com, which is a genealogy website with 43 million public profiles. Those profiles offered a wealth of information, typically including not just individuals' birth and death dates, but also the locations of their births and deaths. Occasionally, they'd even contain photos uploaded by the site's users.

What resulted, in turn, was an extensive collection of trait-and-gene information, ripe for analysis. And it was from that collection that Erlich and his colleagues were able to compile what Nature calls "a single uber-pedigree" involving some 13 million individuals. "We Are Family," as performed by a huge swath of humanity. (But performed anonymously: In making that and similar pedigrees available to other researchers, Erlich and his team stripped names from the data to protect individuals' privacy.)

So what does a database like that the family tree, digitized get us? For one thing, it allows for a kind of longitudinal analysis of given traits, helping researchers to gain insights into the nature-versus-nurture aspects of those traits as they played out over time.

It can also offer insights into how traits are, ultimately, controlled. Given a trait like fertility, say, are there a few genes that exert broad influence ... or is fertility influenced by many genes that have smaller effects? It might also help us understand inherited diseases. (See, for example, the Iceland-based genetics firm deCODE, which is taking advantage of the country's famously rich genealogical data to help determine genetic signatures that can influence diseases and their treatment.)

For all that, Nature notes, it's unclear how, exactly, researchers will use the database for their own purposes. ("Some scientists at the meeting expressed enthusiasm for the project," Heidi Ledford puts it, "but were hard-pressed to come up with a specific experiment using the data.")

Put another way, though, the biggest uses for the results of Erlich's genome-hacking may simply be to come. And those uses would rely on developments that are cultural as much as scientific; on medical records being stored and analyzed in digital, and potentially public, forms. Imagine Erlich's database being linked to individual medical information. Imagine it being linked to DNA sequence data. As Nancy Cox, a human geneticist at the University of Chicago, tells Ledford: "Weve really only begun to scratch the surface of what these kinds of pedigrees can tell us."

Nissan’s Passion Genome Maps Shared Likes

Posted: at 6:42 pm

Ten years after scientists mapped the human genome, auto manufacturer Nissan has created the Passion Genome, an interactive social campaign that maps likes and connections.

The experience allows participants to see the passions, or Facebook likes, they share with their friends in a so-called Passion Portrait, or a "personalized, interactive visualization of themselves," the brand says.

The Passion Portrait includes "DNA-type imagery" and is a "cool, shareable piece of technology," says Erich Marx, director of interactive and social media marketing at Nissan.

"After exploring their top six passion categories, users can explore the entire Passion Genome to see where they fit within an expanded virtual universe of people and passions from across the world," the brand says.

In order to create a Passion Portrait, users connect with Facebook and select a profile photo. The site then analyzes the user's passions.

Unfortunately, at the time of publication, ClickZ was not able to get beyond the "Analyzing Passions" segment of the experience, despite multiple attempts.

However, according to Marx, users ultimately see which of their friends have the same likes in categories such as activities, colleges, bands, TV shows and food.

In addition, it allows users to see if they share likes with everyone who has participated in the Passion Genome.

A Nissan rep would not disclose how many Passion Portraits have been created to date, but says the target is "pre-nesting couples in their early 30s that know who they are and what makes them happy."

What's more, users who share a Passion Portrait via Facebook or Twitter using the hashtag #MyPassionPortrait will be entered for a chance to win one of eight $1,000 gift cards from Amazon.com and have their portraits featured on the Passion Genome website. That's because the Versa Note has a limited time partnership in which it could be ordered through Amazon, although buyers have to go to a dealership to finalize the deal, Marx says. The Amazon deal is not ongoing, but rather a way to "[have] some fun and build awareness," he adds.

Eczema Skin Itch Linked to Staph Infection May Have Better Treatment Solution

Posted: at 6:42 pm

Yuumi Nakamura, M.D., Ph.D., and Gabriel Nuez, M.D., the lead and senior authors of the new research on eczema and staph infections.

Oct. 31, 2013 - For the millions of people suffering from the intensely red, horribly itchy skin condition known as eczema (eksm), the only thing more maddening than their disease is the lack of understanding of what causes it, or makes it flare up from time to time. Now, a new finding made by University of Michigan Medical School researchers and their colleagues may bring that understanding closer and could help lead to better treatments.

In a paper published online in Nature, the team reports that a toxin produced by the common bacteria Staphylococcus aureus popularly known as staph causes immune-system cells in the skin to react in a way that produces eczema-like rashes.

The release of the molecule, called delta toxin, by staph bacteria caused immune-related mast cells in the skin to release tiny granules that cause inflammation. But this didnt occur when skin was exposed to staph strains that lacked the gene for delta toxin.

This link between a specific S. aureus toxin and mast cell degranulation suggests a very specific mechanism, though its not enough to suggest delta toxin from staph bacteria by itself causes eczema, says senior author and U-M professor Gabriel Nunez, M.D. Genetic vulnerability likely also plays a role, he says.

The finding was made in mice, so its too soon to say that the same effect occurs in humans who suffer from eczema, also called atopic dermatitis. But the researchers did find significant levels of staph delta toxin in skin samples taken from patients with eczema.

The researchers showed that delta toxin from staph bacteria caused immune-system cells called mast cells to "degranulate" -- or release granules that trigger inflammation. These electron microscope images clearly show the difference between mast cells with and without delta toxin exposure. (Click photo for larger view)

Nunez, lead author Yuumi Nakamura, M.D., Ph.D., co-author Naohiro Inohara, Ph.D., and their colleagues hope their finding provides a new avenue for developing treatments to help the 15 to 30 percent of children, and 5 percent of adults who have eczema.

Some including patients have previously noted that eczema patients who take antibiotics for other conditions experience a lessening of eczema symptoms. But antibiotics have many drawbacks as long-term therapies for a chronic condition such as eczema most of all, the threat of contributing to the already serious issue of multi-drug resistant Staphylococcus aureus, or MRSA.

The research was funded by the National Institutes of Health, and involved NIH researchers who study S. aureus. Nunez notes that the initial hint of a link came totally by chance, as an incidental finding in an unrelated mast cell study they were conducting. They zeroed in on the little-understood delta toxin and began exploring its power to provoke mast cells to cause inflammation.

Staph Bacteria May Play Role in Eczema-Like Rash, Mouse Study Finds

Posted: at 6:42 pm

WEDNESDAY, Oct. 30 (HealthDay News) -- Researchers who identified a link between staph infections and eczema-like skin rashes say their finding could improve understanding of eczema and help lead to better treatments for the itchy skin condition.

Experiments in mice showed that a toxin produced by Staphylococcus aureus bacteria caused immune system cells in the skin to react in a way that produced eczema-like rashes.

The release of what is called "delta toxin" by staph bacteria caused immune-related cells in the skin to release tiny granules that spur inflammation. This did not occur, however, when skin was exposed to staph strains that did not have the gene for delta toxin, the investigators found.

The study was published Oct. 30 in the journal Nature.

The link between this specific staph toxin and skin rashes suggests a very specific mechanism, but it's not enough to suggest that delta toxin from staph bacteria by itself causes eczema. It's likely that genetics also play a role, said study senior author Dr. Gabriel Nunez, a professor of academic pathology at the University of Michigan.

The discovery was made in mice, and it's too soon to know if the same effect occurs in people with eczema. The researchers did, however, find significant levels of staph delta toxin in skin samples taken from people with eczema.

"We know that 90 percent of patients with atopic dermatitis, also called eczema, have staph bacteria detectable on their skin," Nunez said in a university news release. "But until now, it has not been suspected that the contribution was primary. ... Now we have evidence that there may indeed be a direct link."

About 15 percent to 30 percent of children and 5 percent of adults have eczema.
