Shu Lam

She is all of 25 and may have already made one of the most significant discoveries of our time.

Scientists in Australia this week took a quantum leap in the war on superbugs, developing a chain of star-shaped polymer molecules that can destroy antibiotic-resistant bacteria without hurting healthy cells. And the star of the show is 25-year-old Shu Lam, a Malaysian-Chinese PhD candidate at the University of Melbourne, who has developed the polymer chain in the course of her thesis research in antimicrobials and superbugs.

A polymer is a large molecule composed of several similar subunits bonded together. Polymers can be used to attack superbugs physically, unlike antibiotics that attempt to kill these bugs chemically and killing nearby healthy cells in the process.

“I’ve spent the past three and a half years researching polymers and looking at how they can be used to kill antibiotic resistant bacteria,” or superbugs, she told This Week in Asia, adding the star-shaped polymers work by tearing into the surface membrane of the bacteria, triggering the cell to kill itself.

'Superbugs' could cost US$100 trillion and millions of lives globally by 2050

Using the polymer, bacteria doesn’t exhibit the same resistance as it does to antibiotics and can still be killed after multiple generations of mutations, Lam’s PhD supervisor Professor Greg Qiao said.

“The components of the polymer can also be tweaked differently depending on the application,” said Qiao, who also leads the Polymer Science Group and is a professor of macromolecular chemistry and engineering at the university’s School of Engineering.

The World Health Organisation lists superbugs as a key threat to human health, having adapted to become resistant to all forms of antibiotics. The UN General Assembly has called a meeting this month to address the superbug explosion.

“We think superbugs will cause around 10 million deaths per year by 2050,” Lam said.

Lam’s breakthrough with Qiao on polymers has been published in the research journal Nature Microbiology.

However, Lam’s research is still in early stages, according to Qiao, and much more work needs to be done to verify the best formula and structure, as well as to reduce the dosage and further test toxicity before the substance is completely safe for the human cell.

“Even with all the money in the world, it would take at least five years to go to the first human test, because many resources and work are needed for its commercialisation,” he said.

Lam is to submit her PhD thesis in two months and says she hopes to continue to work in research, rather than opt for medical training like her father, who is a paediatrician.

“I think my career will be mainly focused on research in the medical field,” said Lam, who has already begun pursuing her passion in polymer research during her four-year undergraduate degree in chemical and biomolecular engineering.

“As an undergraduate, she would come to our group for summer work when she had time,” Qiao recalled of Lam.

These days when Lam finds the rare downtime between researching polymers, she likes to watch TV and explore the city. “Being in Melbourne, I have developed an interest in food and really like exploring new cafes and brunch places, so I spend a lot of time trying new food and walking around when I’m not working,” Lam said.

Lam moved to Australia for her foundation studies after finishing primary and secondary school in Malaysia, and is likely stay on in Australia after graduating at the end of the year.

“My main preference would be to continue to stay in research, but I am also looking at career fields outside of polymer research,” she said. “This research is going in different directions,” said Qiao. “One is killing the bug, the other is treating cancer.”

That sinking feeling: ‘superbugs’ may be multiplying in China’s tap water due to world-low hygiene standards, scientists say

Her group is also examining the use of polymers as a drug carrier for cancer patients as well as the treatment of other diseases.

A key project at the moment is the synthetic transplant of cornea in the eye, which involves the use of polymers grown from the patient’s own cells in the lab to replace the damaged cornea.

The operation has already been tested multiple times successfully on sheep, and Qiao hopes to begin the first human trials in Melbourne within two years, working with the Melbourne Eye and Ear Hospital.

Asia Might Have Cracked The Superbug Problem
Ryan Pickrell

Antibiotic-resistant superbugs may have met their match, thanks to new research published in Nature Microbiology earlier this week.

Shu Lam, 24, a Malaysian-Chinese Ph.D student at the University of Melbourne, developed a star-shaped polymer that can tear through the walls of antibiotic-resistant superbugs and eradicate them, reports The Sydney Morning Herald (SMH). Lam’s star-shaped polymerized peptide may be the solution to the superbug problem. “It kills bacteria in multiple ways. We designed it to break the cell wall apart but we also found it can trigger the cell to kill itself,” Lam explained to the SMH. Lam’s superbug-killing polymer is called SNAPPS, an acronym which stands for structurally nanoengineered antimicrobial peptide polymers.

By 2050, superbugs could kill 10 million people a year and cost the global economy $100 trillion, revealed a Review on Antimicrobial Resistance report released in May. The report indicated that superbugs could kill one person every three seconds.

“Even today, 700,000 people die of resistant infections every year. Antibiotics are a special category of antimicrobial drugs that underpin modern medicine as we know it,” Jim O’ Neill, who chaired the review, told South China Morning Post (SCMP).

The U.S. Food and Drug Administration announced that it is pulling antibacterial soaps off the market because they are concerned they contribute to the resistant superbug problem.

Scientists have experimented with peptides — short amino acid chains — before. Previous designs were able to eliminate bacteria, but they were also extremely toxic to the host. Lam’s design is unique because it is larger, and the large size seems to prevent it from harming healthy cells, Lam’s supervisor, Greg Qiao, told the SMH.

Lam’s research has a lot of potential, but it is still in the early stages of development. “Even with all the money in the world, it would take at least five years to go to the first human test,” Qiao explained to SCMP reporters.

The polymer research being carried out by Lam and her team in Australia could potentially also be applied to cancer, Qiao mentioned.

Beyond antibiotics: star-shaped protein kills feared superbugs
Marcus Strom
The Sydney Morning Herald

It's a promising step into a post-antibiotic world.

A PhD student at Melbourne University has developed a star-shaped protein that can rip apart the walls of resistant superbugs – and kill them.

Shu Lam, 24, has had her research published today in the prestigious Nature Microbiology journal.

Bacteria are increasingly resistant to antibiotics, evolving into feared "superbugs" that threaten to kill millions of people a year.

In the US, the Food Drug Administration is pulling anti-bacterial soaps off the market for fear that they are exacerbating antibiotic resistance in some bacteria.

"Our project is to build better alternatives to antibiotics," Ms Lam told Fairfax Media.

Ms Lam and her team from the Melbourne University School of Engineering designed a star-shaped polymerised peptide – which is a large repeated chain of proteins.

"It kills bacteria in multiple ways," Ms Lam said. "We designed it to break the cell wall apart but we also found it can trigger the cell to kill itself."

Ms Lam and the team have given their polymers the perhaps not-so-snappy acronym SNAPPs: structurally nanoengineered antimicrobial peptide polymers.

A peptide is a short chain of amino acids. Scientists have experimented previously with antimicrobial peptides but have found that while they kill bacteria, they are also hugely toxic to the hosts.

Ms Lam has designed her protein chains in star shapes with 16 or 32 arms that are about 10 nanometres in diameter, much larger than other antimicrobial peptides.

Professor Greg Qiao is Ms Lam's supervisor. He said that what is novel in her design is that their relatively large size means it doesn't seem to affect the healthy cells around the bacteria.

"With this polymerised peptide we are talking the difference in scale between a mouse and an elephant," he said. "The large peptide molecules can't enter the [healthy] cells."

Ms Lam and her team tested six different superbugs in vitro, meaning outside a living body. They found that the star-shaped peptide polymer killed the bacteria and did not damage red-blood cells in the in vitro environment.

They also tested the efficacy of the polymer in vivo, inside mice, against one type of superbug bacteria. That bacteria,Acinetobacter baumannii, was killed and the researchers "did not observe any resistance acquisition by A. baumannii".

Associate Professor Cyrille Boyer, at the University of NSW, said it was very promising research but warned its use was still a long way from clinical application.

"The main advantage seems to be they can kill bacteria more effectively and selectively" than other peptides, said Associate Professor Boyer, who is not associated with the research.

Professor Qiao said one of the next steps is to look at how different shapes, such as rings, will work against the superbugs. He also said there will need to be a lot more in vivo research to explore the limits of their toxicity.

However, first signs are promising. The tests undertaken on red blood cells in vitro showed a low toxicity threat.

She probably live there, so she is Aussie citizen. I read local Chinese leaving Malaysia because of no job prospects
 
.
Ever wonder why she never left for Singapore the homeland of Malaysian Chinese?

Or why she never left for China?

@ahojunk do you know if Shu Lam is just a student at Melbourne or a citizen of Aussie?

People always tend to settle in areas they are familiar with. She studied and graduated from Melbourne University and could feel secure in familiar Australian environment.

This is a common phenomenon among foreign graduate students. They have wider supports from the university, the local and national professional academic groups. In this respect , Australia has advantage over China, Singapore and Malaysia.

The most important of all is the job offer to her. And future career prospects.

Very unfortunately, Malaysia is lacking many attractions to retain her top brains. one million Malaysian are staying overseas and most are top brains, either as students, professionals or businessmen.

Malaysian education is gear towards British education. China education is conducted everything in Chinese including physics, biology and chemistry. Definitely she has no way to go China to further her studies as she is most likely English based.

It really depends on the opportunity. This young lady, probably a candidate for the Nobel Prize in Physiology or Medicine, won't lack job offer I believe. Most likely she will join a top-notch US university to continue her work. On the opportunities, with the competitive salaries that China's universities can offer, together with generous research funding, China is attracting more and more young talents from abroad. I know a Malaysian Chinese with Stanford PhD joined the faculty in Tsinghua University in Beijing. It is also not uncommon to see western scholars on the faculty roster of China's universities these days.

She is a Malaysian from a town called Batu Pahat. And is a Phd student.
So she isn't an Australian citizen yet. But I know that with this discovery you can he sure she already got a job waiting for her

It doesn't matter where she is from. Australia is inclusive. As Shu Lam has the talents and skills, I have no doubt she will be offered Australian citizenship. I hope she stays in Australia.

Hi as a Singaporean Chinese myself, reading your comments caused me to fall on the floor rolling and laughing
