Delta-24-RGD - A Virus Found to Target and Eliminate Cancer Cells of the Brain
Cancer is a very hot topic in scientific research, today, because of the apparent lack of understanding of biological processes underlying. Without control of this path biological, it is not possible to develop surefire treatment and / or prevention of certain types of cancer. It should not be very far to find a critic or a bioassay for the exploitation of these cavities in the media. Despite the frequency of inspections in the field of oncology (the study of tumors / Cancer) has improved our understanding of the exponential growth manifestation, diagnosis, prevention and treatment of cancer. A simple look at the reduction in the morbidity of patients suffering from cancer in recent decades, some comfort should be for most people skeptical.
Despite the many advances in cancer research, the results of fly under the radar of the media. It lies within these small discoveries, which forms the basis for future treatments and cures. Recently, a group of researchers has been a step closer to a solution to save the lives of his puzzle.
The study, conducted by researchers at the UT MD Anderson Cancer Center in Houston and funded by the National Cancer Institute, analyzes the effects of tumor on the brain stem cells of mice, developing adenovirus (delta-24 - LD). As adenovirus, I think, to a virus by researchers. This has been the most aggressive on the brain tumor, glioblastoma multiforme, known resistant to chemotherapy and radiotherapy. The plot in this particular project stems from his attempt, known in 2003 and studied in the research.
The study found that in 2003, Delta-24 eliminates brain tumors and 60% of the mice. The latest study was conducted, but on the reality of stem cells, the tour continues postoperative tumor growth, so that tests on stem cells glioma. This led to a direct comparison of survival in the period between the control group (no intervention) and the treatment group (delta-24 has received the injection). The survival time of mice, the treatment of nearly doubled patients in the control group. The result is obvious: mice, that the injection of adenovirus showed the lengthening of life expectancy. The success of the study is not complete.
Researchers have tried to analyze, rather than cause and effect. It seeks information on the actual physiological processes contribute to the death of cells in the brain. For the first time, Adenovirus-mediated cell death (autophagy), it was found that the direct method of cell death in stem cell tumor of the brain. It was also recalled that the therapeutic virus is not to change the normal brain tissue. This leads with great hope, because tumors in the brains of these mice, brain tumors is similar in humans. This similarity is irregular in shape invasive and metastatic, or spread, of the properties. The study especially on the results of these restrictions and the need for further research, but it makes a fascinating premise, and possibly the method of treatment of tumors that are not on the brain. The study, only a remarkable given the constant efforts and put cancer by researchers. It must be remembered that our race for the healing is not a sprint but a marathon course that must be carefully and methodically ran.
