Cloning Cells Eliminate Skin Cancer

Skin cancer seem daunting indeed. But do not worry, the scientists in the United States stated that they have successfully treated a man who suffered from skin cancer are the way to cloning one of the blood cells the body's immune system to attack disease.

Men aged 52 years is free of melanoma two years after treatment. Before the patient contract advanced melanoma that has spread to tuberculosis and limfa.


As reported New England Journal of Medicine, medical technique is done with the isolate one opponent cancer cells, T-cell, and create some of its billion-cloning in the lab and return the cells to the body of the patient.

In two months, the results of scanning showed tumor in the lung and lymph gland men was missing and two years after the treatment he is still free of cancer.
The researchers emphasize that this therapy is still need more extensive research to examine the effectiveness of that system against various types of cancer diseases.

Scientists in the UK warns more testing needs to be done to prove the effectiveness of the treatment. Scientists at Fred Hutchinson Cancer Research Center in Seattle to concentrate on the type of white blood cell called CD4 + cells T.

From the sample of white blood cells of the men, they can select the cells, CD4 + T cells that have a specifically directed to the chemicals found on the surface of melanoma cells.

Already Found Virus Causes Skin Cancer

One virus, previously unknown, may be the cause of a form of skin cancer is a rare but especially off the impact on the elderly and the body's immune system was weak due to AIDS.

The researchers at the University of Pittsburg Cancer Institute in the United States believe they have found perpetrators, which can cause infection, after identifying the DNA sequence of the virus in 80% tumor cells Merkell.

DNA belonging to a foreign virus, called Merkel cell polymavirus (MCV), which integrates into the tumor genome itself in a way that indicates that the virus is triggered the growth of cancer.

If the new virus was the cause, the virus offers promise for the treatment of cancer is very aggressive. Experts suspect the virus was shut because of the protein causes cancer genes or the growth of the tumor.

"The information that we may be able to earn their way to the examination of blood or a vaccine to improve the handling of disease prevention and help," said Dr. Patrick Moore, who with colleagues published the findings in the journal Science.

Merkell cell carcinoma of the developing nerve cells that react to touch or pressure. Events have been increased threefold in the last 20 years; now there are as many as 1,500 cases per year in the United States.

Some 50% of advanced disease patients live for nine months or less. Merkel cell carcinoma is not the first cancer associated with a virus, and will not be the last.

The virus causes of cancer is the most exposed to HPV, or human papillomavirus, which can cause cancer and cervix become targets of two new vaccines anti-cancer, Gardasil and Cervatix, from Merck & Co Inc and GlaxoSmithKline Plc. Kaposi `s sarcoma, the most dangerous conditions on public AIDS patients and the most common cancer in Africa, also caused by a virus.

Prevent Skin Damage with Broccoli Extract

Dr. explained. Paul Talalay of Johns Hopkins University, broccoli sprout seed extract can reduce redness and damage to the skin up to more than one-third. "But, this is not hindsight solar," said Talalay, as cited by Reuters. Extracting this will only help fortify skin cells to fight the effects of UV radiation.

Together with his team, Talalay a test of six people with various doses in some small areas of skin. The part is then displayed with a short wave UV radiation, which causes quite a burn rate that varies.

They then compare the redness on the skin that are given treatment and that is not. At the highest dose, the extract reduced redness and swelling by an average of 37 percent, and long-term effect. Two days after treatment stopped, the effects remain visible.

These effects vary widely among the volunteers, who obtained protection from 8 to 78 percent depending on genetic differences. "What we see important because it also works in humans," Talalay said. However, it still suggests further research is needed on how this should be applied to humans.

"Not like solar screen that provides physical barrier against UV rays by absorbing, obstruct, or otherwise light, the extract helps increase the production of protective enzymes that defend against skin damage related to UV," a time. Especially on people with problems on the immunity system, such as patients in the transplant. However, this still does not replace extract the solar curtain.

During the 15 years, Talalay has been researching sulforafane, component, which is in the broccoli sprout extract. The results of this study indicate that the development of tumors in animals given the amount of material causes of cancer can be prevented.
