The Buyer Is…

Thermo Fisher Scientific has agreed to buy Life Technologies for $13.6 billion, reports Bloomberg News. Thermo Fisher will be paying $76 a share for the company, adds Daily Scan sister publication GenomeWeb Daily News. GWDN notes that Canada's Financial Post had suggested in January that Life Tech was seeking a buyer and, shortly after that, the company confirmed it was undergoing a strategic review.

The Wall Street Journal notes that Thermo Fisher had to "[fend] off competition at the end of an auction process from a private-equity group and another industry bidder, Sigma-Aldrich." Ross Muken, an analyst at International Strategy & Investment Group, tells Bloomberg that the price was higher than what analysts had expected. The Life Tech purchase gives Thermo "reach across all the major technologies," he says, adding, "You now have a unique customer touch and a portfolio others will be unable to match."

The deal is expected to close toward the beginning of 2014, GWDN adds.

In the Last 10 Years

The Human Genome Project was completed 10 years ago yesterday, and in the intervening time, there have been a number of advances in genome sequencing and biology, the National Human Genome Research Institute says. According to its calculations, the cost to generate a human genome sequence has dropped from about $1 billion when the project began in 1990 to between $10 million and $50 million when the project ended to between $3,000 and $5,000 today. Also, in the past 10 years the number of human genomes that have been sequenced has skyrocketed from just one to thousands, and there are now nearly 3,000 genes with known phenotypes or disease-causing mutations.

"On the 10-year anniversary of the completion of the Human Genome Project, it is appropriate to celebrate our accomplishments over the past decide and to reflect on the impact of genomics on research, medicine, and society," Eric Green, the NHGRI director, says in a statement. "By improving our understanding of basic genome biology, the genomic underpinnings of disease and genomic medicine, the field gets ever closer to its ultimate goal — improving human health through genomics research."

The NHGRI numbers also note that the number of drugs with pharmacogenetic information on their labels has jumped from four in 1990 to more than 100 in 2013.

The Right Question?

The US Supreme Court today is hearing arguments in the Association for Molecular Pathology et al. vs. Myriad Genetics gene patenting case, bringing up the question of whether genes, particularly isolated genes, may be patented. The question the court has to consider, New York University law professor Rochelle Dreyfuss tells NPR is: "Is the thing that's isolated significantly different from the way that it was when it was in nature?" Products of nature cannot be patented.

The New York Times asks, though, whether that question is outdated. "Another question could trump it: Has the field of genetics moved so far so fast that whatever the court decides, it has come too late to the issue?" writes Andrew Pollack at the Times. He adds that whole-genome sequencing may not infringe on single, isolated gene patents and that cancer centers with such technologies are sequencing cancer genes to help determine the best treatments for patients.

"Events on the ground have overtaken the law," James Evans, a professor at the University of North Carolina at Chapel Hill tells the Times. He adds that decision "will be much more ideological than it will be practical."

AMDeC Saying Good-bye

AMDeC said late on Friday that it is shutting down.

The board has decided to close the doors on the Academy for Medical Development and Collaboration, or AMDeC, after 15 years, it said, though it did not say why. The organization was in created in 1997 to "facilitate and encourage collaboration among the major research institutions in the [New York] region.

"We are proud to say that we have achieved this — and much more," it said in a statement.

AMDeC President and CEO Maria Mitchell told Daily Scan sister publication GenomeWeb Daily News less than seven months ago that it was expanding its mission and developing new initiatives to help its members save on costs to better ride through the economic downturn.

This Week in PLOS

Two microbial species are especially common in the core community of microbes inside the human bed bug, Cimex lectularius, according to a PLOS One study. The University of Cincinnati's Regina Baucom and company used 16S ribosomal RNA sequencing to characterize collections of intra-bed bug microbes, using 31 bed bug samples collected at eight urban sites across Ohio. The analysis turned up a range of microbial species, researchers say. But the core microbiome in the blood-sucking pests was made up of mainly two microbes: the obligate endosymbiont Wolbachia and an unnamed gamma-proteobacterium that resembles an endosymbiotic species previously found in the leafhopper.

An international team led by investigators in Germany explores the relationship between genetic variation on the Y chromosome, geography, and language groups in native South Americans. As they reported in PLOS Genetics, the researchers looked at SNP and short tandem repeat patterns on the Y chromosomes of 1,011 men from 50 tribal populations in 81 South American locales. Though they did not see genetic variant profiles with clear ties to tribal geography or language groups on the continent, investigators did find a new Y chromosome haplotype that seems to have been introduced to the area within the past 6,000 years.

In PLOS Neglected Tropical Diseases, researchers from Italy and Slovakia report on a phylogeographical analysis of the parasitic roundworms Ascaris lumbricoides and A. suum species. Using a PCR-restriction fragment length polymorphism method, the team assessed nuclear gene profiles in 143 Ascaris worms from pigs and another eight from human hosts. Together with mitochondrial gene sequence data on the same samples, the PCR-RFLP profiles allowed the team to assess phylogeny and phylogeography of the worms, which came from Italy, Slovakia, Hungary, Syria, Romania, and Pakistan. "Results obtained suggest that A. suum and A. lumbricoides may be variants of the same species," study authors say, "with the lack of fixed genetic differences and considerable phylogeographic admixture confirming an extremely close evolutionary relationship among these nematodes."

Steak, Bacteria, and Heart Disease

A link between eating red meat and heart disease has been known for a while, but just how eating a steak leads to atherosclerosis isn't quite clear, writes The Economist. Stanley Hazen from the Cleveland Clinic, though, says the effect might be mediated through the gut microbiome.

As they report in Nature Medicine, Hazen and his team found that intestinal microbes metabolize L-carnitine, a trimethylamine found in red meat, to trimethylamine-N-oxide, which, in mice, leads to atherosclerosis. Trimethylamine-N-oxide levels, they added, were higher in human omnivores than in human vegetarians or vegans.

The necessary microbes, The Economist notes, are not always present — vegetarians and vegans are less likely to be able to produce trimethylamine-N-oxide, even after taking carnitine supplements or when persuaded "in the interests of science" to eat a steak. And when antibiotics are used to kill off gut bacteria, even steak eaters produce less trimethylamine-N-oxide.

In a cohort of nearly 2,600 people, plasma levels of it and its L-carnitine precursor were associated with increased risk for cardiovascular disease and cardiac events like heart attack or stroke. And in mouse studies, the researchers found that prolonged exposure to L-carnitine led mice to develop atherosclerosis.

While "the precise chain of events linking microbes to heart disease is still unclear," The Economist adds that "this study suggests that people looking for the link between heart disease and the eating of meat have been ignoring two culprits, carnitine and bacteria."

Mass Spec on the March

Mass spec is taking over the world, pharma researcher Derek Lowe writes this week on his blog In The Pipeline.

Or, at least, it's taking over his world, which is to say, the world of biopharma research.

The technology might still be struggling for acceptance in realms like clinical proteomics, but in biopharma "there are just so many things that you can do with modern instrumentation that the assays and techniques just keep on coming," Lowe writes, singling out a recent paper in Angewandte Chemie in which researchers used MALDI mass spec to detect deacetylation on a histone peptide.

The assay offers an alternative to fluorescence-based assays that, Lowe notes, have "(notoriously) been shown to cause artifacts."

And this example isn't a one-off, he adds. A number of such mass spec-based assays have been published in journals, with even more unpublished examples "worked out inside various biopharma companies for their own uses."

Supreme Showdown

The US Supreme Court is gearing up to hear arguments in the Myriad Genetics gene patenting case on Monday. The Myriad patents cover the isolated BRCA1 and BRCA2 genes, which increase the risk of breast, ovarian, and other cancers, while critics say isolated DNA is a product of nature and, therefore, is not patentable. The implications of a decision in The Association for Molecular Pathology v. the US Patent and Trademark Office and Myriad Genetics case, Heidi Ledford at Nature writes, may not be as broad as some think.

"Symbolically, this case is a pretty big deal," Duke University's Robert Cook-Deegan tells Nature's Ledford. "But the practical consequences of it are limited."

University of Medicine and Dentistry of New Jersey's Jeffrey Rosenfeld and Christopher Mason from Cornell University recently wrote in Genomic Medicine that, according to their analysis, about 41 percent of the human genome could be covered by patent claims. Ledford at Nature notes that other researchers like Christopher Holman, a law professor at the University of Missouri-Kansas City, and Harvard Law School's Nicholson Price place that percentage closer to a quarter.

The case, Ledford adds, focuses on isolated gene patents, and there are other types of patents that also cover genes. And Harvard's Price says that whole genome sequencing likely would not infringe any gene patents as it looks at the full scope of the genome rather than at isolated DNA. Cook-Deegan adds, though, that if the court does take a broad view of the case, whole-genome approaches could be affected.

A decision in the case is expected toward the end of June, Nature adds.

This Week in Science

In Science this week, a team led by Rockefeller University researchers report on the identification of key mutations in a gene encoding ribosomal protein SA, or RPSA, as the possible cause of isolated congenital asplenia — a rare condition in which a person is born without a spleen, which increases the risk of serious bacterial infection. The group conducted an unbiased analysis of the exome sequences of a group of ICA patients and found seven mutations on RPSA, resulting in the expression of about half the normal level of its protein.

Meanwhile, in Science Translational Medicine, researchers from the Baylor College of Medicine and the University of Texas MD Anderson Cancer Center publish a report on the identification and characterization of breast cancer circulating tumor cells involved in metastasis. Using CTCs from peripheral blood mononuclear cells of breast cancer patients, the team identified a potential genetic signature of brain metastasis and found that cells expressing the signature were highly invasive and capable of generating brain and lung metastases when xenografted in nude mice.

In Science Signaling, an international team reported a protein phosphorylation network in the abscisic acid, or ABA, signaling pathway in Arabidopsis thaliana. By integrating genetics with phosphoproteomics, the investigators were able to identify multiple components of the ABA-responsive protein phosphorylation network.

For Next Year

US President Barack Obama unveiled his budget proposal for fiscal year 2014 yesterday, in which he outlined his plan to raise $600 billion in new revenue, according to the New York Times. In remarks, Obama said that this budget replaces the across-the-board sequester cuts "with smarter ones, making long-term reforms, eliminating actual waste and programs we don't need anymore," according to a White House transcript.

For the National Institutes of Health, this proposed 2014 budget would give a slight, 1.5 percent increase as compared to 2012 to its coffers, bringing its total funding to $31.3 billion, ScienceInsider reports. "Everything's relative," says Francis Collins, the NIH director, according to ScienceInsider. "Considering what we've been going through in FY '13, what's being proposed here is really gratifying." NIH is funded at $30.8 billion for 2013 under a continuing resolution.

As Daily Scan sister publication GenomeWeb Daily News reports, the National Human Genome Research Institute would receive a 1 percent budget increase under the Obama plan. GWDN notes that NHGRI aims to continue following its strategic plan to focus less on fundamental genomics and more on translating those findings into the clinic.

The National Science Foundation, meanwhile, would see an 8.4 percent increase from 2012 levels, giving it a total budget of $7.6 billion, the Chronicle of Higher Education says, adding that the Department of Energy Office of Science would also see a boost, bringing its budget to $5 billion, a 5.7 percent increase over 2012 levels.

The reaction to the budget has been mixed, a separate ScienceInsider post shows. Representative Lamar Smith (R-Texas) gives the budget proposal "a failing grade," and says the House science committee, which he chairs, will hold hearings on Obama's budget priorities.

Meanwhile, Hunter Rawlings, the president of the Association of American Universities, says that his group "strongly [supports] the President's proposals to eliminate the ill-considered across-the-board sequester and to increase funding for the National Institutes of Health, the National Science Foundation, the Department of Energy Office of Science, Department of Defense basic research, the National Endowment for the Humanities, and some key student financial aid programs." He adds, though, that the budget isn't perfect and that his group does "not agree with everything in this budget. But it is a strong start."

And the Risks, Too

A large study investigating the best oxygen dose for premature infants did not adequately spell out the risks of the investigation to the infants' parents in the informed consent form, the New York Times reports.

The consent form pointed out possible benefits of being in the high- or low-oxygen groups, but did not mention risks related to being in either of those groups, according to a letter from the Office for Human Research Protections, which is part of the US Department of Health and Human Services, to the lead institution on the study, the University of Alabama at Birmingham. High levels of oxygen can result in blindness or other eye problems in infants while low levels of oxygen increase the chance of death. Instead, the consent form mentioned that there was a risk of abrasion to infants' skin from the oxygen monitoring device, the Times adds.

Slightly more than 1,300 infants took part in the study, which was published in the New England Journal of Medicine in 2010. That article reported that there was no difference in retinopathy or death between the high- and low-oxygen groups.

UAB tells the Times that the consent form was developed by researchers at the University of California, San Diego, and that the review boards of all 23 participating institutions approved the form. UAB's Richard Marchase also tells the Times that the infants in the study had a lower mortality rate than other infants who were eligible for the study but did not enroll.

He adds that he told the Office for Human Research Protections that, going forward, "we will to the best of our ability let the subjects or their parents know as thoroughly as possible what previous studies suggest in terms of risk" and that "we are going to be very sensitive to that going forward as we look at these consent forms."

Still, Michael Carome from Public Citizen's Health Research Group, which uncovered the letter to UAB, said HHS needs to investigate this matter and apologize to the participants' families, according to NPR. "The word 'unethical' doesn't even begin to describe the egregious and shocking deficiencies in the informed-consent process for this study," he said in a statement.

Millions for a Letter

The family of Francis Crick, a co-discoverer of the structure of DNA, put a few of his things, including a letter to his son about the structure of DNA as well as his Nobel Prize itself, up for auction. And they have fetched millions of dollars, Reuters reports.

Indeed Crick's letter to his son sold for $6 million at Christie's , making it the most expensive letter ever sold — beating the prior record of $3.4 million for a letter sent by US President Abraham Lincoln to schoolchildren. Christie's had estimated Crick's letter would sell for between $1 million and $2 million.

Crick's Nobel Prize, which was auctioned by Heritage, went for $2.27 million, four times more than its estimate, Reuters adds. The purchaser was not identified.

The Associated Press adds that half of the proceeds from the sales at Christie's will go to the Salk Institute for Biological Studies in La Jolla, where Crick was a professor, and 20 percent of the Heritage sales will go to the Francis Crick Institute in London, which is scheduled to open in 2015.

This Week in Nature

In Nature Genetics, a multi-institute team from the UK report on the identification of common and low-frequency variants associated with severe early-onset obesity. The scientists conducted single-nucleotide polymorphism and copy number variation association analyses in more than 1,500 children with obesity and about 5,300 controls. They found four new loci associated with obesity and discovered a previously reported 43-kb deletion at a specific locus was significantly associated with the condition. They also found a significant burden of rare, single CNVs in severely obese cases.

Meanwhile, in Nature Methods, investigators from the German Cancer Research Institute publish a report describing a new method to systematically map genetic interactions in human cancer cells using combinatorial RNAi and high-throughput imaging. Through automated, single-cell phenotyping, they measured genetic interactions across a "broad spectrum" of phenotypes, including cell count, cell eccentricity, and nuclear area. They also mapped genetic interactions of epigenetic regulators in colon cancer cells, recovering known protein complexes.
