New test to detect bladder cancer
Researchers from the Hospital Clinic of Barcelona and Puigvert Foundation promoted a novel procedure to locate the bladder cancer based on a urine sample. The sample, according to experts, is more reliable and effective than existing and would go on sale in 2013.
Scientists say that this test is more reliable than those that exist today, because it is capable of recognizing up to 12 genes related to the pathology and 2 which are closely linked to the likely aggressiveness of the tumor , a combination that really has a sensitivity high and specific in diagnosing bladder cancer. Studies currently underway, however, are able to identify only a few genes or only one.
Bladder cancer after the prostate is the second most common tumor in the genitourinary tract, affecting more than 15000 people per year in Spain.
In the course of the disease, people with bladder cancer should undergo an average of 20 cystoscope. This procedure is not pleasant or comfortable, since it consists in entering with a camera through the urethra to examine the bladder and examine the evolution of cancer.
Finally, we mention that the chief of Urology at the Hospital Clinic, Antonio Alcaraz, said to be ratified by the values of this study with about a thousand patients in three hospitals in Spain, one Dutch and one from Austria.
Genes linked to lung cancer
Three genes are implicated in the genesis of lung cancer, apparently found on human chromosome 14, and two of them are involved in fetal development of the lungs. This was affirmed by researchers at Cold Spring Harbor Laboratory in New York County (United States).
In this study the three genes involved (TTF1, NKX2-8 and PAX9) would be activated and would cause a pattern of fetal gene expression, causing abnormal proliferation of cells that give rise to the tumor.
Apparently, the mutations of these genes is common in some types of lung cancer. The mechanism by which these genes are activated in the fetal stage of growth in the adult is not known exactly, but if you know that if you disable these genes could halt tumor growth.
The most important thing is that the tumor may regress if these genes are turned off. Although this is still under study and will take years before it can be applied directly as a treatment for advanced lung cancer.
Walnuts are defending from prostate cancer
Nuts may help against prostate cancer by regulating the activity of genes involved, hindering the growth of the tumor (if present).
The research suggests a University of California, directed by Dr. Paul Davies and presented at the meeting in San Francisco of the American Chemical Association.
The team of Davies has worked with some rodents genetically engineered to develop prostate cancer. Read the rest of this entry »
