Soil bacteria helps kill cancers

By Caroline Parkinson Health editor, BBC News website

Posted Image

A bacterium found in soil is a showing promise as a way of delivering cancer drugs into tumours.

Spores of the Clostridium sporogenes bacterium can grow within tumours because there is no oxygen.

UK and Dutch scientists have been able to genetically engineer an enzyme into the bacteria to activate a cancer drug.

Experts said it would be some time before the potential benefits of the work - presented to the Society of Microbiology - were known.
The work is being presented to the society's autumn conference at the University of York.

The spores grow only within soild tumours, such as breast, brain and prostate tumours and not in other tissue in the body, where oxygen is present.

Healthy tissue 'unscathed'

Researchers have been investigating the possibilities of clostridium "vectors" to deliver cancer drugs for decades.

End Quote Professor Nigel Minton University of Nottingham

The scientists from the University of Nottingham and Maastricht University were able to genetically engineer an improved version of an enzyme into C.sporogenes.

In animal tests, a drug was also injected into the bloodstream which becomes active only when it is triggered by this enzyme.
It then destroys only the cells in its vicinity - the tumour cells.

Professor Nigel Minton, who led the research, said: "Clostridia are an ancient group of bacteria that evolved on the planet before it had an oxygen-rich atmosphere and so they thrive in low oxygen conditions.

"When Clostridia spores are injected into a cancer patient, they will only grow in oxygen-depleted environments, ie the centre of solid tumours.

"This is a totally natural phenomenon, which requires no fundamental alterations and is exquisitely specific.

"We can exploit this specificity to kill tumour cells but leave healthy tissue unscathed."

The team are now planning to work with other researchers on patient trials, due to start in 2013.

Nell Barrie, senior science information officer at Cancer Research UK, said: "Finding ways to target treatments to cancer cells while leaving healthy cells unharmed is a key aim of researchers around the world.

"But it's a difficult problem to solve, especially because every cancer is different. This particular approach hasn't yet been tested in patients so it will be some time before researchers know whether it will offer real benefits."

“One, remember to look up at the stars and not down at your feet. Two, never give up work. Work gives you meaning and purpose and life is empty without it. Three, if you are lucky enough to find love, remember it is there and don't throw it away.”

Cuba Announces Release of the World's First Lung Cancer Vaccine

From the island nation known for the quality of its cigars comes some pretty big news today: Xinhua reports that Cuban medical authorities have released the first therapeutic vaccine for lung cancer. CimaVax-EGF is the result of a 25-year research project at Havana’s Center for Molecular Immunology, and it could make a life or death difference for those facing late-stage lung cancers, researchers there say.

Alpha radiation treats prostate cancers

A trial of a new cancer drug, which accurately targets tumours, has been so successful it has been stopped early.

The death rate was 30% lower in the group taking radium-223. Those patients survived for 14 months on average compared to 11 months in the dummy group.

The trial was abandoned as "it would have been unethical not to offer the active treatment to those taking placebo", said Dr Parker.

Scientists discover virus that kills all types of breast cancer ‘within seven days’




Scientists at the Penn State College of Medicine said this week they have discovered a virus that is capable of killing all types of breast cancer "within seven days" of first introduction in a laboratory setting.


The virus, known as adeno-associated virus type 2 (AAV2), is naturally occurring and carried by up to 80 percent of humans, but it does not cause any disease.

Scientists reverse sickle cell anemia by turning on fetal hemoglobin

October 13, 2011

Not long after birth, human babies transition from producing blood containing oxygen-rich fetal hemoglobin to blood bearing the adult hemoglobin protein. For children with sickle cell disease, the transition from the fetal to adult form of hemoglobin – the oxygen-carrying protein in blood -- marks the onset of anemia and painful symptoms of the disorder.

Now, new research led by Howard Hughes Medical Institute (HHMI) investigator Stuart H. Orkin of Children's Hospital Boston, Dana Farber Cancer Institute, and Harvard Medical School shows that silencing a protein known as BCL11A can reactivate fetal hemoglobin production in adult mice and effectively reverses sickle cell disease. The new finding, reported October 13, 2011, in Science Express, reveals that BCL11A is one of the primary factors involved in turning off fetal hemoglobin production.

It seems as though scientists are just now discovering the methods and vehicles for which cancer and diseases are to be cured. Given another 10 years, I wonder how the details perfecting these treatments will be in terms of eradicating cancers and diseases.

Here is one of those methods I am taking about:

For the first time, researchers have found a way to inject a precise dose of a gene therapy agent directly into a single living cell without a needle. The technique uses electricity to "shoot" bits of therapeutic biomolecules through a tiny channel and into a cell in a fraction of a second. http://www.physorg.c...ne-therapy.html

European court ruling 'threatens stem cell work'

By Helen Briggs Health editor, BBC News website

Europe's highest court has ruled that stem cells from human embryos cannot be patented, in a case that could have major implications for medicine.

Scientists say the Court of Justice decision may impede European research into the use of stem cell therapies, or drive research abroad.

The ruling follows a challenge by Greenpeace over a patent for nerve cells from embryonic stem cells.

Embryonic stem cells have the ability to turn into any tissue in the body.

They offer the hope of one day being able to treat diseases such as Parkinson's, stroke, heart disease and diabetes, if technical hurdles can be overcome.

The ruling concerned a method invented by a German professor, Oliver Bruestle, for converting human embryonic stem cells into nerve cells.

The court's decision had been seen as critical for research into the use of stem cells as treatments for a range of diseases.

The European Court of Justice said in a statement: "The use of human embryos for therapeutic or diagnostic purposes which are applied to the human embryo and are useful to it is patentable.

"But their use for purposes of scientific research is not patentable."

It added: "A process which involves removal of a stem cell from a human embryo at the blastocyst [early embryo] stage, entailing the destruction of that embryo, cannot be patented."

Prof Pete Coffey of the Institute of Ophthalmology in London, who is researching the use of stem cell treatments for blindness, said the decision was "devastating".

He told the BBC: "This could really halt the progress of stem cell therapies for as yet untreatable diseases."

Prof Coffey is among several leading UK scientists who wrote a letter expressing "profound concern" over an earlier recommendation by the advocate-general of the court.

Scientists were concerned that the ruling would threaten the future of medical research, saying companies in Europe would be less likely to invest in research to develop therapies using embryonic stem cells.

But Greenpeace in Germany, which triggered the case, argued it was unethical to issue a patent based on cells from a human embryo, which was then destroyed.

The court ruled in the group's favour.

'Ridiculous'

Commenting on the decision, Prof Austin Smith of the Wellcome Trust Centre for Stem Cell Research, University of Cambridge, said: "This unfortunate decision by the court leaves scientists in a ridiculous position.

"We are funded to do research for the public good, yet prevented from taking our discoveries to the marketplace where they could be developed into new medicines.

"One consequence is that the benefits of our research will be reaped in America and Asia."

Prof Bruestle, of Bonn University, who was initially awarded the patent, said: "With this unfortunate decision, the fruits of years of translational research by European scientists will be wiped away and left to the non-European countries.

"European researchers may conduct basic research, which is then implemented elsewhere in medical procedures, which will eventually be reimported to Europe. How do I explain this to my students?"

Is this part of occupy stuff? Without patents 1% of corporation owners can't make their bazzilions of dollars on those stem cell therapies.

Malaria vaccine trial raises hope

A malaria vaccine has shown promising results in a clinical trial in Africa.

Infants given the prototype vaccine had about half the risk of getting malaria compared with those who did not receive the jab, say researchers.

The vaccine, known as RTS,S, is one of two experimental malaria vaccines being tested around the world.

'We can live to 150 and stay healthy': Professor says first 'wonder drugs' could be ready this decade

Drugs that can slow the ageing process are likely to be available this decade, raising the prospect of people living to 150 or longer.
'Wonder' pills that help the body repair itself are in the early stages of development and will help us live well into our second century - while stem cell therapies will boost our quality of life.

^Living healthily to 150 in our current economy would be an absolute burden though, right? Imagine the stagnation of management that didn’t change for decades, heck... imagine having to work for over a hundred years? When this does start to happen, it’s going to be real interesting to see how culture revolutionises along with it.

I'd do 5 different professions, each job lasting 20-25 years, well why not 50 years and living to ripe old 300 :D 50x5 = 250+30 eduction+ 20-40 years retirement (live to 320)

Mobile phone brain cancer link rejected

Further research has been published suggesting there is no link between mobile phones and brain cancer.

The risk mobiles present has been much debated over the past 20 years as use of the phones has soared.

The latest study led by the Institute of Cancer Epidemiology in Denmark looked at more than 350,000 people with mobile phones over an 18-year period.

I see people constantly raising similar points. Apparently they forget that they won't be obligated to partake in these aging treatments. If you think that wouldn't be able to cope with the "burdens" of an extended life, just don't take part in the treatments.
