PolyU scientist finds novel use of African mushroom in cancer research

07.02.2012
A young scientist from PolyU's Food Safety and Technology Research Centre has successfully prepared highly stable selenium nanoparticles by using the polysaccharide-protein complex extracted from the African Tiger Milk mushroom.

A young scientist from The Hong Kong Polytechnic University (PolyU)'s Food Safety and Technology Research Centre (FSTRC) has successfully prepared highly stable selenium nanoparticles by using the polysaccharide-protein complex extracted from the African Tiger Milk mushroom.

The preliminary study discovered that these stabilized selenium nanoparticles can significantly inhibit the growth of breast cancer cells by apoptosis.

With this breakthrough, FSTRC Associate Director Dr Wong Ka-hing, who is also an Assistant Professor of PolyU's Department of Applied Biology and Chemical Technology, has won the Young Investigator Award in the 2011 International Conference of Food Factors (ICoFF 2011) with the theme "Food for Wellbeing-from Function to Processing".

Selenium is a trace element which is essential for human health. The study of selenium nanoparticles has become a hot topic because of their excellent bio-availability, low toxicity and strong anti-cancer activity. However, nanoparticles would easily stick together, and their special properties would be lost once the aggregates exceed nano-size. That is why scientists around the world have been exploring ways to stabilize the nanoparticles.

Dr Wong's award-winning study is entitled "Preparation of Highly Stable Selenium Nanoparticles with Anti-Cancer Activity under a Food Grade Redox System" – which means the ultimate products could be consumed as functional food or health products. The study is the first of its kind in terms of preparing highly stable selenium nanoparticles with the use of mushroom polysaccharide-protein complexes as the stabilizers. Apart from its potential as functional foods, the finding has also provided insights on using these novel nanoparticles as new drug for cancer chemoprevention.

In the next stage of cancer research, Dr Wong would evaluate the anti-cancer activity of those stabilized selenium nanoparticles on small animals, and elucidate the underlying mechanism of their growth inhibition effects on the breast cancer cells.

The polysaccharide-protein complex currently in use is extracted from the sclerotium of Tiger Milk mushroom. Dr Wong would also further investigate whether its other developmental stages (e.g. fruiting body) could be used for this cancer research. PolyU has partnered with a mushroom farm to produce Tiger Milk mushrooms and support further research.

The ICoFF at which Dr Wong received his award was organized by the Association of Agricultural Chemists (AOAC) International (Taiwan Section). This year more than 1,300 participants from 30 countries have attended the event, during which numerous international renowned scholars and experts were invited to give lectures on health promotion, diseases prevention and other health issues related to food.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
