Singapore Attracts Life Science Companies

Today, Singapore continues to capitalize on its geographic location as one of the crossroads of the world to grow life science companies. About 70 airlines serve Singapore, making it a gateway to Southeast Asia. As a testament to their commitment to the life science industry in the 21st century, Singapore built two state-of-the-art biomedical research parks. The Biopolis, a biomedical research complex of seven buildings that houses 2,000 scientists, opened in September 2003. The first tenants were the Genome Institute of Singapore and the Bioinformatics Institute. Buildings named Centros, Genome, Matrix, Nanos, and Proteos hold biomedical research institutes of the Agency for Science Technology and Research (A*STAR), which oversees scientific efforts under the Ministry of Trade and Industry. The Biopolis tenants share high-quality technical services, such as DNA sequencing, proteomics, NMR, and FACS (flow activated cell sorting) facilities. The Biomedical Sciences group of Singapore

Novel therapies for age-related diseases such as Alzheimer's and Parkinson's

In their current study, published in the online edition of the journal Nature , Conboy and her team found that old muscle produces elevated levels of a molecule called TGF-beta, which is known to inhibit muscle growth. The researchers then showed that the muscle-deteriorating effects of TGF-beta can be reversed by blocking its pathway in old mice. In the experiments, the researchers used RNA interference, which can silence specific genes, to inhibit the molecules that act downstream of TGF-beta to prevent cells from multiplying. They then locally injured the muscles of treated mice, as well as untreated old and young mice, by injecting a small amount of snake venom, which killed muscle tissue in the immediate vicinity. After five days, the team found that the young mice were able to produce healthy cells to replace damaged tissue. The treated older mice, whose inhibitory pathways were suppressed, were able to regenerate new cells in much the same way. Not surprisingly, old untreate

In Silico Transfer of Neurotransmitter Transporter Motif Between Structurally Analogous Protein (Catechol-O-methyltransferase)

Here is a abstract that i had submitted at the 3D sig:Structral Bioinformatics at the 1st Structural Bioinformatics Meeting at ISMB 29-30 July 2004, Glasgow, Scotland, UK. I do not know how relevant is the issue to this day. I am interested in working further in this area and i am interested in collaborating. Do let me know your comments also pour your suggestions on how to further this study. In silico methods can be used to design protein, based on stability and functionality using computational methods rather than laboratory procedures (Comet et al., 2000). The changes taking place due to the transfer of motif region from human Catechol-O-methyltansferase to rat Catechol-O-methyltransferase can be studied effectively using computational methods. This will provide insight for further development of the study about the function of neurotransmitter region of catechol-O-methyltransferase and its involvement in the Parkinson’s disease. Catechol-O-methyltransferase (COMT) catalyzes the t

GINA Aftermath - Consumers Still Wary of Genetic Tests

Previously blogging on GINA Dawn of the GATTACA era! now Industry Survey Shows: The surveyors found that only five percent of consumers said that they were “very likely” to take a disease-specific genetic test in the next few years, and 15 percent said they would be “likely” to take one. A total of 35 percent said that they would not submit to genetic tests, with 14 percent citing concerns about privacy, 5 percent saying they would not want to know about the results of their tests, and 16 percent saying both reasons would compel them to avoid genetic tests. Although more than 50 percent of those who responded said that they are concerned about getting cancer or heart disease, only 4 percent of those said they had taken a genetic test for a particular disease. Two-thirds of those who did have a genetic test were advised to do so by a doctor. The respondents had about the same comfort level of sharing genetic information with their spouses or partners as with their doctors, 72

Boehringer Ingelheim to Acquire Actimis Pharmaceuticals for $515M

Boehringer Ingelheim will acquire Actimis Pharmaceuticals through a structured buyout in which Boehringer Ingelheim will acquire shares of Actimis depending on the achievement of several successive milestones with Actimis’ leading asthma compound AP768. If AP768, currently in Phase I development, is successfully advanced into a Phase III, Boehringer Ingelheim will own 100% of Actimis’ shares. Upon successful completion of the entire development program, the total deal will be worth $515 million. AP768 interacts with CRTH21, a target for asthma and allergic rhinitis. Previous to the currently ongoing Phase I trial, the compound was shown to have a more effective mechanism of action across multiple available animal models compared to currently marketed leukotriene receptor antagonists , according to the companies.

CoMet' – a tool to study the integrated machinery of cell and predicts components that effect cancer

A new computer-based method of analyzing cellular activity has correctly predicted the anti-tumour activity of several molecules. Research published today in BioMed Central's open access journal Molecular Cancer describes 'CoMet' – a tool that studies the integrated machinery of the cell and predicts those components that will have an effect on cancer. Jeffrey Skolnick, in collaboration with John McDonald, led a team from the Georgia Institute of Technology who have developed this new strategy. As Skolnick explains, "This opens up the possibility of novel therapeutics for cancer and develops our understanding of why such metabolites work. CoMet provides a deeper understanding of the molecular mechanisms of cancer". Identification of metabolites with anticancer properties by Computational Metabolomics The small molecules that are naturally produced in cells are called metabolites. Enzymes, the biological catalysts that produce and consume these metabolites are cr

Researchers create molecule that nudges nerve stem cells to mature

The last time i blogged on stem cells it was rather about a challenge in Fresh hurdle for stem cell hunt , but this time its more on a positive note and fairly quite an interesting and welcome news... a SERENDIPITY! Inspired by a chance discovery during another experiment, researchers at UT Southwestern Medical Center have created a small molecule that stimulates nerve stem cells to begin maturing into nerve cells in culture. "This provides a critical starting point for neuro-regenerative medicine and brain cancer chemotherapy," said Dr. Jenny Hsieh, assistant professor of molecular biology and senior author of the paper, Small-molecule activation of neuronal cell fate, Jay W Schneider, Zhengliang Gao, Shijie Li, Midhat Farooqi, Tie-Shan Tang, Ilya Bezprozvanny, Doug E Frantz, Jenny Hsieh SUMMARY: We probed an epigenetic regulatory path from small molecule to neuronal gene activation.

Some people never learn: the genetics of learning from our mistakes

In its simplest sense, we imagine that learning occurs through a series of positive and negative rewards. Some actions lead to pleasure, others to pain, and it seems reasonable to expect that people will repeat the actions with pleasurable results and avoid those that ended in pain. Yet, we all know people who aren't deterred by the idea of punishment. We all know people who never seem to learn. Could there be a physical reason, hidden in their genes?

Genome Viewers/Editors - Three of the Best

A number of online and offline genome are viewers available, each with it’s own set of pros and cons. Here is an overview three. Artemis Artemis is a genome viewer available from Sanger Institute. Its a java based tool with a 3-paned interface window that depicts the genome at various resolutions. Alternating between the different resolutions is a bit tricky but once you get a hold of it shouldn’t be difficult. There is a also search tool that allows your to track down the particular feature that you’re looking for. A great feature of Artemis is that it allows you to edit the sequence annotations and features. Although the tool isn’t perfect and is a bit finicky at times, it gets the job done. Artemis supports the most common filetypes -EMBL, GENBANK, FASTA or raw format. Extra sequence features can be added in in EMBL, GENBANK or GFF format. The best thing I like about Artemis is that there is a web version as well as an offline version, which means once you get used to it you ca

PURE: a webserver for the prediction of domains in unassigned regions in proteins

Protein domains are the structural and functional units of proteins. The ability to parse proteins into different domains is important for effective classification, understanding of protein structure, function, and evolution and is hence biologically relevant. Several computational methods are available to identify domains in the sequence. Domain finding algorithms often employ stringent thresholds to recognize sequence domains. Identification of additional domains can be tedious involving intense computation and manual intervention but can lead to better understanding of overall biological function. In this context, the problem of identifying new domains in the unassigned regions of a protein sequence assumes a crucial importance. Accumulation of domain information of sequence homologues can substantially aid prediction of new domains. In this paper, we propose a computationally intensive, multi-step bioinformatics protocol as a web server named as PURE (Prediction of Unassigned REg

Protein Linked To Alzheimer's Disease Also Has Role In HIV Progression

A protein related to heart disease and Alzheimer's is found to be a factor in HIV. The apolipoprotein (apo) E4 isoform has been implicated in neurodegeneration in Alzheimer's disease, cardiovascular disease, and stroke. Now, investigators at the Gladstone Institutes, the University of California, San Francisco, the University of Texas Health Science Center at San Antonio, and the Infectious Disease Clinical Research Program, Uniformed Services University, Bethesda, Maryland have shown that this troubling protein is a risk factor for AIDS progression rates and promotes entry of HIV into cells.

Crystal structure errors — in CSD too

Many of you involved in structure based drug discovery will know very well about the numerous problems and errors in the data found in the Protein Data Bank (PDB) especially concerning the ligand structures. There have been a lot of publications about such errors, e.g. in Jones et al. J Mol. Biol. (1997) 267 :727, and I heard various conference presentations about this topic too, e.g. by Gerard Kleywegt (University of Uppsala), titled “Protein crystallography: not as simple as ABC then?” at Bryn Mawr, Philadelphia (15-19 October 2007) eChemInfo meeting . The errors are often blamed on the low resolution of the structures involving large protein structures (often thousands of atoms). One would assume that the small molecule crystal structures of the Cambridge Structural Database ( CSD ) do not have such errors, since they have much higher resolution and dealing with small molecules. Let me correct that wrong assumption! Do you want to know more?

New target to enhance anti-cancer drug sensitivity found in translation

Several times i have discussed the the topic of anti-cancer targets, Novel Enzyme Inhibitor Paves Way for New Cancer Drug: Agent Proves Effective Against Melanoma Cells; Researchers Find that a Small Molecule Can Activate an Important Cancer Suppressor Gene. The development of resistance to anticancer chemotherapeutic agents remains a large problem. In some cases, such resistance is associated with altered control of a cellular process known as translation, which is central to the generation of proteins. New data, generated by Jerry Pelletier and colleagues, at McGill University, Montreal, have identified a drug that can enhance the sensitivity of mouse cancer cells to standard anticancer chemotherapeutic agents. In the study, small molecules were screened for their ability to inhibit the initiation of translation by modifying the function of a protein known as eIF4A, which has a central role in translation initiation. A class of natural drugs known as cyclopenta[b]benzofuran flavag

EBI-Led Consortium to Study How to Turn EU Bio-Databases Into Bioinformatic Network

The European Commission has awarded €4.5 million ($7 million) to a consortium of 32 research organizations, universities, and companies from 13 countries to determine how to transform Europe’s biomedical data resources into a transnational “sustainable integrative bioinformatics network” for the life sciences. The consortium is led by the European Bioinformatics Institute. The first year and a half of this project, called ELIXIR, for European Life-science Infrastructure for Biological Information, is aimed at gathering input, performing technical-feasibility studies, and doing user surveys among researchers who generate and use data, and develop tools. Much like the Oxford English Dictionary, which will remain useful as long as people speak English, so, too, will “the infrastructure for biological information … continue as long as people are interested in biology, health, and medicine,” she said. But provisions must be made to allow that to happen, including upgrading the infrast

Interactive WikiProteins Project Invites Researchers to Annotate Biological Concepts

Hoping to bring together “a million minds” to annotate proteins, a team of researchers has launched a large-scale, community-based project called WikiProteins that combines automated text, data, and concept mining, manual annotation, and a newly developed software component called the Knowlet. The project, which aims to annotate proteins and protein-related biomedical concepts such as diseases or organisms, will be powered by a platform technology designed by a group of scientists and a Rockville, Md.-based startup and will be made available free of charge in perpetuity for the scientific community and the public. Called WikiProfessional , the platform “in a technical sense powers the community-version that we have now put out there, but you could take exactly the same technology platform and install it locally at a pharmaceutical company for them to do drug-lead discovery,” said Albert Mons, a computational linguist and co-founder of the startup, Knewco. “Philosophically we wante

CAS Scientists Help To Explain Diversity of Molecular Structures

By studying the variety of chemical substances and their structures recorded in the CAS REGISTRY SM database, Chemical Abstracts Service (CAS) scientists have discovered that a limited number of molecular shapes are the frameworks for a disproportionately large percentage of reported substances. As shown in the CAS study , half of the known organic chemical substances can be described by just 143 shapes. The analysis, published in The Journal of Organic Chemistry , explains why certain molecular frameworks are more likely to be used in new compounds and may also help identify new regions of chemistry space ripe for exploration.

A blogger studies GSK's pending layoffs and the politics behind them

GSK: Money-Green Outside, Pink-Slip Inside GSK is indeed wielding the ax today and tomorrow. I'm hearing that that the smallest cuts are around 40% of the entire research staff at the various sites. This is big, and it's bad. . . says Derek GlaxoSmithKline has been going through some sort of mid-life crisis recently. Their chairman, Jean-Pierre Garnier, just retired amidst the mutter of angry shareholders , for one thing. And the company has been splashing out on some very flashy acquisitions, such as the Sirtris deal which has just now completed. This is all going on against the backdrop of the Avandia disaster, and a perceived drought of current clinical successes . Now the company is cutting their own head count in research, to what sounds like a pretty serious degree. There have been substantial cuts at their sites in Italy and the UK, and the Research Triangle and Pennsylvania sites are getting it even harder, from what I'm hearing. Some chemistry areas are losi

Automatic content for the people

Anyone who has ever built a website knows that maintaining it is a lot of work. There’s just making sure it hasn’t gone offline because the httpd daemon died. Constant monitoring for script kiddies and their SQL injections. Not to mention continually feeding it with fresh content, lest your audience become bored and desert. I’ve always thought it would be cool to build a site that could more or less look after itself. There’s a myriad of content management systems to choose from, most of which are somewhat hackable in whatever language they happen to be coded in. One of the more mature in this respect is Drupal - which is the engine behind Eureka! Science News . It’s a fully-automated science news portal, using a bunch of customised Drupal modules to aggregate, cluster, categorise and rank articles. First impressions are excellent. Coders will enjoy this post at Drupal explaining how it all works.

Fresh hurdle for stem cell hunt

Previously blogging on the topic of regenerative medicine in Regenerative Medicine Start-Up Created out of ORNL . A Nobel Prize-winning scientist says it could be tougher than first thought to harness the healing power of stem cells in medicine. It had been hoped a single "master" cell could potentially be used to repair all damage in a single organ. Stem cells may be more varied than previously thought. Professor Mario Capecchi , from the University of Utah, found surprising clues that different stem cells might be working together in the same organ. This means experimental treatments relying on the wrong type might fail. Professor Capecchi, writing in the Nature Genetics, said the finding suggested stem cell biology could be "more complicated" than previously thought, which could be bad news for patients hoping for the swift arrival of new therapies. Bmi1 plays an essential part in the self-renewal of hematopoietic and neural stem cells. To investigate its role

How Sequencing Is Done

At JGI, we use whole-genome shotgun sequencing. This is a technique for determining the DNA sequence of a genome by randomly shearing the DNA, sequencing multiple fragments whose sequences overlap, and inferring the original sequence by reassembling the fragments. Three sizes of fragments are sequenced, 2-4 kb (kilobase, or 1000 bases), 8-10 kb, and 40 kb. This explanation follows the procedure for 2-4-kb fragments.

Roadrunner was possibly only five to 50 times less powerful than the human brain

Fastest supercomputer in the world proves one in a million billion Roadrunner was always expected to be fast out of the blocks. And after a test run one night in the city of Poughkeepsie, New York, its creators are far from disappointed. Built from microchips originally destined for games consoles, Roadrunner is the world's latest supercomputer. Yesterday it was officially crowned the fastest computer around, having performed a record million billion calculations per second. As an indication of how fast this is, manufacturers explained that if 6 billion people were to do one sum a second on calculator, it would take 46 years to do what RoadRunner could do in a day. The world's first supercomputer, the Cray 1 built in the mid-1970s, would take 1,500 years to finish a calculation that Roadrunner would perform in two hours. For six months, the computer will direct its formidable processing power at scientific problems. It will analyse how HIV vaccines should best be administered,

Unofficial Google Shell

goosh.org - the unofficial google shell ( http://goosh.org /). It is pretty neat and useful in its neonatal state itself, like to read a feed, you can type, for eg: r http://www.google.com/reader/public/atom/user/11136726768885096694/label/cbn-roll and gets default 4 latest feeds, or you can check out a ncbi accession by typing, for eg: NP_001108376 and get to the Fugu fish refseq link. The most useful thing is the fact that it it text based and quite easy to parse visually as well as via scripts. Another cool feature for me right now is the shell translation, like to get the english word for the norwegian word 'hvor', all I have to do is type: t no en hvor which correctly says: translating "hvor" from "no" to "en": "where" More discussion going on at http://tech.slashdot.org/article.pl?sid=08/06/02/222234&from=rss .

Regenerative Medicine Start-Up Created out of ORNL

Battelle Ventures has spun out a firm from the U.S. Department of Energy’s Oak Ridge National Laboratory (ORNL), with an initial $1.5 million seed investment. The company, called NellOne Therapeutics, will develop regenerative medicines. The funding will be tranched based on key technical milestones. Towards a "holy grail" in human medicine: the ability to restore organs damaged through trauma, disease, cancer, or even the normal aging process. Tissue or organ repair has been the ultimate goal of surgery from ancient times to the present day. Clearly, there is a lot of interest in the regeneration of tissues, and tissue repair in organisms is within reach. However, we are a long way from understanding how to coax the human body into regenerating complex body parts after injury or disease. As an example, regeneration of amputated limbs in amphibians - “epimorphic” regeneration which includes cellular dedifferentiation in the injured tissues of the limb stump and proliferat

Gene that Induces a Magnetic Signature in Cells Found

A team of scientists have found a way to make human cells produce magnetic nanoparticles by introducing a gene from bacteria. The gene MagA was tested in human kidney cells, though the investigators believe that it will probably be most useful in tracking cell movement in transgenic animals via MRI. “MagA can be thought of as the equivalent of green fluorescent protein but for magnetic resonance imaging,” says Xiaoping Hu, PhD, professor of biomedical engineering at Emory University and the Georgia Institute of Technology . Dr. Hu anticipates that MagA could find similar applications to green fluorescent protein, with the advantage that magnetic fields can penetrate tissues more easily than light. MagA comes from magnetotactic bacteria, which can sense the Earth's magnetic field. It encodes a protein that transports dissolved iron across cell membranes. When put into animal cells, MagA triggers the accumulation of lumps of iron oxide a few nanometers wide, the researchers explain

Novartis to Buy Protez for $100M

Novartis has decided to acquire Protez Pharmaceuticals for $100 million at close of the agreement. Novartis will pay up to $300 million if certain clinical milestones, regulatory approvals, and commercial targets are achieved. Protez will become a stand-alone subsidiary of Novartis, maintaining its operations in Malvern, PA. Protez’ only clinical candidate, PZ-601, is an injectable antibiotic in the carbapenems class of agents. Protez commenced a 100-patient Phase II study for PZ-601 in May 2008 in the U.S. to evaluate the safety and efficacy of PZ-601 in patients with complicated skin and skin structure infections, including cellulites, abscesses, infected wounds, and ulcers. The firms believe that this compound has the potential to be used in bacterial infections resistant to other medicines including MRSA. “This acquisition,” remarks Christopher M. Cashman, Protez president and CEO, “underscores our company’s infectious disease expertise and novel antimicrobial programs. We beli

The good news in our DNA: Defects you can fix with vitamins and minerals

As the cost of sequencing a single human genome drops rapidly, with one company predicting a price of $100 per person in five years, soon the only reason not to look at your "personal genome" will be fear of what bad news lies in your genes. University of California, Berkeley, scientists, however, have found a welcome reason to delve into your genetic heritage: to find the slight genetic flaws that can be fixed with remedies as simple as vitamin or mineral supplements . "There are over 600 human enzymes that use vitamins or minerals as cofactors, and this study reports just what we found by studying one of them," Rine said. "What this means is that, even if the odds of an individual having a defect in one gene is low, with 600 genes, we are all likely to have some mutations that limit one or more of our enzymes." The subtle effects of variation in enzyme activity may well account for conflicting results of some clinical trials, including the confusing data

Elevated Levels of Metabolites in CSF Play a Role in HIV Patients with CNS Damage

A team of scientists from The Scripps Research Institute found an increased concentration of certain metabolites in the cerebrospinal fluid (CSF) of monkeys with SIV-induced central nervous system (CNS) disease, a model for HIV patients with CNS damage. The investigators used global metabolomics to assess the levels of metabolites in CSF before and after SIV-induced encephalitis appeared. They found elevated levels in four categories: carnitine, acyl-carnitines, fatty acids, and phospholipids. Consistent with this, the team reports, a protein known to be important in the generation of fatty acids was increased in the brains of monkeys with SIV-induced encephalitis. The elevation in free fatty acids and lysophospholipids correlated with increased expression of specific phospholipases in the brains of animals with encephalitis, according to the researchers. One of these, phospholipase A2 isoenzyme, is capable of releasing a number of the fatty acids identified. It was expressed in d

USDA Releasing Genomic Data from 150 Bird Flu Viruses

The United States Department of Agriculture has released the complete genetic sequences of 150 different avian influenza viruses and will make the information available through the National Institutes of Health’s GenBank. The USDA said on Friday that the sequencing data is part of the federal government’s Initiative on Avian Influenza, and that this information will be combined with studies that compare the viruses’ ability to infect poultry such as chickens, turkeys, and domestic ducks. This virus research that generated this data was conducted by the USDA’s Agricultural Research Service’s Southeast Poultry Research Laboratory (SEPRL), by the University of Georgia, the Ohio State University, the University of Delaware, and the University of Alaska-Fairbanks. "The project's ultimate goal is to sequence 900 avian influenza viruses from the SEPRL repository," David Suarez, a researcher with SEPRL, said in a statement. "These include avian influenza viruses col
