The USP15 biological thermostat: A promising novel therapeutic target in cancer

Monday, February 20, 2012

After years studying the molecular bases of glioblastoma - the most common brain tumor and one of the most aggressive of all cancers, the group led by Dr. Joan Seoane , Director of Translational Research at the Vall d'Hebron Institute of Oncology (VHIO) and ICREA Research Professor has today published a study in Nature Medicine identifying USP15 as a critical protein in cancer which, thanks to its molecular characteristics, shows enormous therapeutic promise.

USP15 promotes tumor progression by activating the TGF? pathway. Playing a highly significant oncogenic role in glioblastoma, TGF? is a powerful immunosuppressant allowing the tumor to escape the host immune system. It also acts as an angiogenic factor inducing blood vessels, promotes tumoral invasion, activates cancer stem cells, and in some tumors, induces metastases.

USP15 as a "Biological Thermostat" at the core of a TGF? chain reaction

Dr. Seoane's team has unmasked the USP15 enzyme as activator of the TGF? chain reaction. In tumors the USP15-TGF? axis is deregulated due to USP15 gene amplification leading to an aberrant TGF? activation.

USP15 acts by controlling and correcting the TGF? activity in the same way that a thermostat regulates temperature. If the TGF? activity is high, it reduces; and if it is low, it increases the TGF? activity. USP15 therefore achieves optimal TGF? activity.

Protein stability is regulated through the elimination or aggregation of ubiquitins, small proteins that establish which molecules need to be eliminated. This process is finely regulated by deubiquitinating enzymes (DUBs) such as USP15 which determine the correct level of a protein under certain physiological conditions. In this orchestrated manner, USP15 controls and adapts the TGF? receptor stability and, therefore, the activity of the pathway.

The problem arises when, in some tumors, the USP15 gene is amplified due to genetic mutations and the enzyme is over produced. The thermostat breaks down and is therefore only sensing the "cold" resulting in the overactivation of the TGF? pathway. Remarkably, this is not only a phenomenum of glioblastomas since the USP15 gene has also been found activated in other types of cancer such as breast or ovarian cancer.

Dr. Joan Seoane explained "When we inhibited USP15 in a real model of human glioblastoma, TGF? activity decreased and the tumor did not develop. USP15 regulates tumor progression and is critical in cancer."

DUBs (deubiquitinating enzymes): a novel avenue in therapeutic targets

Sometimes potentially powerful therapeutic targets are found but are not pharmacologically accessible due to their biochemical characteristics. "Enzymes in general - particularly deubiquitinating enzymes (DUBs) such as USP15, can easily be deactivated and are therefore good therapeutic targets", Seoane commented, "our results, generated thanks to the funding received from the Spanish Association Against Cancer (AECC), show exciting new promise in improved treatment of cancer patients.".

Learning Facts Concerning Motorcycle Fairings! - Peruvian Embassy

Throughout a large number of pieces of the planet, the a large number of typical form of motor vehicle is a motor cycle also recognised as motorbike. Due to the fact that they tend to be affordable plus is used for a myriad of purposes, majority of the males prefer that would buy many of these motorcycles. Amongst the different types of motorcycles which are that you can buy currently, the a large number of favored ones tend to be sport bikes which tend to be used for racing purposes. Precisely what makes many of these bikes stand out tend to be their fairings. According that would the automotive dictionary, motorcycle fairings tend to be practically a protective shell which is placed over headlights plus different electric components of the bike. Mostly sports plus racing bikes use many of these gsxr fairings.

Streamlining on motorcycles was actually done initial in the early 1920s however, the name fairing was actually provided whenever they began in order to be used in aircrafts. As per scientific studies, motorcycle fairings increase the frontal area of the bike by 5% in comparison that would a naked bike. Today, a number of businesses manufacture many of these fairings and so people can easily discover Yamaha fairings, Honda fairings plus Suzuki fairings amongst other people. Nevertheless, right now there tend to be a number of types of motorcycle fairings which is found plus you requirements that would judge the kind of fairing they prefer before actually purchasing them.

Initial off, right now there is full-body fairing which, because indicates by the name, means which both upper plus lower portions of the motorcycle tend to be protected. The entire engine plus chassis is protected by full motorcycle fairings in the event of a crash. Rather of the engine cover, it will certainly be the fairings which slide found on the road. Hence, people can easily use Suzuki fairings that would cover their bike especially in case they ride at high speeds. Next, right now there is half-faring which extends below the handlebars, consists of a windscreen plus covers the cylinder box. Half faired models currently have fairing kits in the market which is used that would make them into full models.

Bikini and / or quarter fairing covers a minimal area such as headlights. Additional types of motorcycle fairings include dolphin fairing, torpedo fairing plus dustbin fairing. Whether or not people use Yamaha fairings and / or any kind of different brands, right now there tend to be a number of benefits which is associated with suzuki fairings. Reducing air drag is their primary purpose plus apart from protecting the engine, they also protect the rider from air borne hazards. Wind induced hypothermia can easily also be prevented with the aid of these motorcycle fairings. Throughout touring bikes, fuel consumption is also reduced with the employ of fairings. Cleaning fully-faired bikes is also simple given that the water simply glides off them.

Fairing kits is easily purchased within the market for installation purposes.

Drones over U.S. may pose security risks ? Latin Business Today

By | Feb 8, 2012

WASHINGTON, Feb. 8 (UPI) -- Thousands of tiny unmanned aircraft or drones flying into civilian airspace over the United States can pose a security threat as they may be difficult to monitor in the long run and some craft may fall into enemy hands, security analysts say.

Although debate over the use of surveillance drones, approved by Congress this week, centers on civil liberties and individuals' rights, a much greater risk of hostile drones entering U.S. airspace undetected isn't being considered, analysts said.

The Federation Aviation Administration said up to 30,000 drones could be in airspace shared with airliners carrying passengers.

Current lobbying for the drones insists there will be enough qualified experts to operate the drones safely and not endanger airborne human traffic but there are many questions unanswered about how the drone operators would be regulated.

More important, at a time when government defense cutbacks are the norm, little consideration is being given to potentially unfathomable costs of maintaining a vast fleet of drones, their monitors and operators and the whole regulatory framework required to run the system efficiently and safely.

There is risk, too, that terrorists will attempt to penetrate the drone network with unpredictable consequences for the safety of the set-up as well as citizens, analysts said.

Once the bill has been signed by U.S. President Barack Obama, the FAA Reauthorization Act will allow the FAA to give drone traffic the go-ahead and develop regulations for testing and licensing by 2015.

The expectations are that the law eventually will streamline processes for multilevel licensing of drone flights by federal, state and local police and other government agencies.

The legislation follows vigorous campaigning by defense and security industries that see drones as a multibillion-dollar growth area.

The defense and security industries have already made up for declining revenues in direct defense acquisitions by developing new business to counter cyberthreats, border body scanners and giant merchandise scanners and a range of software to counter Internet fraud, identity fraud called phishing and hacking of sensitive corporate and government data.

The American Civil Liberties Union said the legislation could severely undermine Americans' privacy. The Electronic Frontier Foundation echoed those privacy concerns.

U.S. defense and security forces deployed drones of varying sizes in Afghanistan and Iraq. The CIA's armed Predator drone program targeted al-Qaida leaders but officials said smaller drones were deployed outside U.S. diplomatic areas in Iraq to monitor the safety of U.S. officials during their movements within the country.

In addition to the drones, the race is on to develop unmanned aircraft that can safely share airspace reserved for civilian aviation.

There's both military and commercial interest in having unmanned aircraft that can fly unaided by human pilots, most of the time.

Initially, unmanned aircraft likely to be released for sharing airspace with civilian airliners will have the option to require a pilot. Eventually, however, they could go unmanned and fly into airspace used by manned airliners using devices on board and control centers on the ground, industry data indicated.

The idea of civilian aircraft flying virtually at the mercy of unmanned craft cruising in their midst has delayed commissioning of such craft, both for practical and psychological reasons. But support for unmanned craft joining civil aviation is catching on, reports indicated.

Several companies are deep into research and development of optionally piloted aircraft. Among these, Aurora Flight Sciences of Manassas, Va., is experimenting general aviation Diamond DA42 planes to be able to market it as intelligence, search and reconnaissance planes.

Mav6 Blue Devil 2 airship has been designed to run pilotless or to have a pilot on board when required. The aerospace company, which has headquarters in Vicksburg, Miss., has designed the Blue Devil 2 airship to accommodate a pilot when necessary.

The 370-foot airship can hover at 20,000 feet for five days and function as a network hub for drones and ground sensors and as a surveillance craft.

Northrop Grumman used a pilot to show off its Firebird last year but the company says the plane can fly just as well without a pilot.

Industry analysts said the research and development drive toward pilotless planes was rooted both in defense priorities to deploy an optionally piloted aircraft in difficult conditions and in defense needs to find new uses for unmanned aircraft that are likely to be made idle with the pullout from Afghanistan.

Hundreds of Predator class unmanned aircraft and some high-flying Global Hawks planes are likely to become available with the drawdown in Afghanistan.
