Rational Design of Engineered Arginine Depleting Enzymes as Multi-potent Anti-cancer Agents

23.09.2016

A novel multi-potent drug removes arginine from the blood and kills cancer cells.

Arginine deprivation has become a new cancer treatment paradigm and has exploited for treatment of various cancers. Arginine is an essential amino acid for the growth of cancer cells. Deprivation of arginine induces cancer cells death but it is generally well tolerated in normal cells.

The successful use of Arginine Deiminase (ADI) to treat argininosuccinate synthetase (ASS)-deficient tumors has opened up new possibilities for targeted therapy. Nevertheless, many ASSpositive cancers are resistance to ADI.

By rational drug design, researchers at The Hong Kong Polytechnic University (PolyU) have developed a thermostable arginase (BCA-PEG20) to treat both ADI-sensitive and ADI-resistant cancers.

BCA-PEG20 has demonstrated to have antitumor activities both in vitro and in vivo in lung cancer, liver cancer, colorectal cancer, gastric cancer, cervical cancer and other tumors.

As a novel multipotent anti-cancer drug, BCA-PEG20 is able to work as a single agent and combine with other chemotherapeutic agents to enhance treatment effect.

Special Features
• BCA-PEG20 is safe and effective
• BCA-PEG20 can treat drug-resistant cancers
• BCA-PEG20 can augment the therapeutic effect of other chemotherapeutic agents

Applications
• As a multipotent targeted therapy for cancers that are auxotrophic for arginine
• As a “chemo-enhancer” to augment the effect of other chemotherapeutic agents

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
