How to wrangle cancer’s deadly protein
Posted by Jes Andersen-U. Copenhagen on January 27, 2015
Three of the four most fatal cancers are caused by the protein “Ras”—because it mutates or simply because it ends up in the wrong place at the wrong time.
Ras has proven an elusive target for scientist trying to cure the deadly diseases. Now chemists at the University of Copenhagen has discovered an unknown way for Ras to find its proper place in the cell. Their discovery may lead to completely novel approaches to curing cancer.
Ras proteins inhabit the interior wall of each and every cell in the human body. Their role is to activate cell division or cell growth, so cancers develop if the protein starts to permanently trigger cells to grow and split: a process known as misregulation.
Ras misregulates if it misses its correct location on the cell wall: its membrane.
What the scientists discovered is that Ras cannot reach its designated location if the membrane has the wrong shape, explains Professor Dimitrios Stamou.
“If the curvature of the cell is right, Ras goes to the right place. If the membrane is too straight or too bent, it does not. And Ras is very much like any other worker. If it never finds the way to its workplace, it is not likely to get any work done,” says Stamou.
Lethal lung, colon, and pancreas cancers
Ras proteins are thought to be misregulated in upwards of 30 percent of all cancers, and are specifically linked to highly lethal strains in lungs, colon, and pancreas.
For three decades researchers have been searching for ways to squelch the killer protein. Their lack of success has given Ras a reputation as the “undruggable cancer target.”
Stamou’s research is moving in an entirely new direction.
“If Ras goes off the rails because of changes in the curvature of the cell, perhaps we should target whatever changes the shape of the cell membrane,” says Stamou. “This is a change of perspective similar to when we went from flying with hot air balloons to taking off with fixed wings and propellers.”
Looking for a correlation between cell shape and Ras misregulation was unusual, even bordering on controversial, says Jannik Bruun Larsen, a postdoctoral student.
The team was investigating how the proteins attach themselves to the cell wall, and Larsen tried to attach Ras to a variety of simulated cell membranes formed into small spheres or vesicles of varying sizes.
Ras would attach more readily to smaller balls. These are more curved than large and Larsen started to see a pattern.
“For more than a decade, people thought that the constituents of the cell wall was what controlled where Ras was localized. We have shown that at least one other aspect, namely membrane curvature, governs where Ras ends up in the cell and is therefore likely to be a factor in cancer development,” says Larsen.
‘We have started’
All of the research so far has taken place on simulated systems in test tubes. The next big challenge is to uncover how these effects play out in living systems, asserts Stamou.
“It will be ten times more difficult to uncover these effects in living systems but it needs to happen. We have started, and we really hope others will follow,” says Stamou.
“It may prove complicated to develop a drug that changes the shape of cells but I am certain that the discovery of the shape/misregulation correlation will at least lead to new ways to diagnose cancers.”
The findings appear in the journal Nature Chemical Biology.

Poor sleep can make us feel down, worried and stressed. So it’s no surprise that how well we sleep has a direct impact on our physical and mental health. Sleep problems such as insomnia are a common symptom of many mental illnesses, including anxiety, depression, schizophrenia, bipolar disorder and attention deficit hyperactivity disorder (ADHD).
To squeeze or not to squeeze? I’ll admit that I’m no skin saint. I have stood in front of the mirror on a number of occasions as a teenager with a big pimple staring right back at me. And yes, despite being advised not to, I have squeezed, picked and popped.
“Life is a series of addictions and without them we die”. This is my favourite quote in academic addiction literature and was made back in 1990 in the British Journal of Addiction by Isaac Marks. This deliberately provocative and controversial statement was made to stimulate debate about whether excessive and potentially problematic activities such as gambling, sex and work really can
It’s not uncommon to hear people wishing that they had a better memory. “If only I weren’t so forgetful”, they complain. “If only I could reliably remember my computer password, and that my neighbour’s name is Sarah, not Sandra.” If this sounds familiar then I know how you feel.
Most people know sleep is important. But few know a lack of it can put us at greater risk of heart disease and obesity. Many of us don’t get enough sleep on a regular basis. It might be due to a sleep disorder, busy social life, new baby, long working hours, shift work or just staying up too late binge-watching Netflix.
"PET scanning is a great technology and very effective, but using it in this way doesn't seem to make any difference for these cancers that have a relatively poor prognosis," says Mark Healey
If you’ve eaten a fabulous meal recently, the experience was pleasant, comfortable and pain-free because your stomach and intestinal system worked seamlessly to move the food along and eventually absorb it.
Someone with panic disorder does not know how to turn off the false alarm process once it gets going and must endure a terrifying experience of unknown duration, even if there is nothing apparent to fear. We all take in squintillions of units of information daily. Our brains have to filter data so that we can conduct some what rational lives without being overwhelmed.
Our body loves us, but it needs to know we love our lives in order for it to do all it can to help us survive. The change in body energy activated by the love alters our internal chemistry and makes a difference. When you are willing to do the work, and live in your heart, magic can happen.
Researchers at CSIRO and University of Queensland have developed an app called Harlie that is designed to chat with humans. Unlike Siri and Google Now – which are designed to answer specific questions – Harlie is designed for small talk.
Some wild west African chimpanzees are teetotallers, whereas others are frequent drinkers given the opportunity – consuming the equivalent of three pints of strong lager per day.
