Cancer Tumor Cell Therapy: Virus Versus Virus In a recent article published by Reuters, a group of researchers claims to have been able to genetically modify the mostly known cold-causing, adenovirus to attack cancer tumor cells, which is not new to the lot of cancer treatment as the US Food and Drug Association earlier approved the use of herpes virus to attack skin cancer cells. This kind of cancer cell therapy is not as impossible as it was curiously examined by scientists before since the genetic engineers, with the use of advances in gene modification, have developed progressive ways of manipulating certain viruses to attack tumor cells. The head of the development of viruses modified to attack malignant and connective tissue tumor

Podhjacer counter argues this disadvantage by developing the “ important addition” they made in the development of the oncolytic virus. The tumor cells are not the only cells attacked by the genetically modified adenovirus, but also the stromal-- connective structural tissue in an organ-- cells that are responsible for tumor growth and metastasis. Professor Young sees that although this is an important addition to oncology, metastasis prevention is also at the immune system’s expense because, as this oncology should be sequential as other types of cancer treatment are needed number of times, the immune response would not be as active as the first time the genetically modified virus is introduced. This is because the modified virus will not positively attack all tumors, as immune responses between patients are not the same which was also seen earlier in the 50s and 60s when patients either recovered or died, after doctors learned of the viral infection recovery of patients from …show more content…
Podhjacer’s group’s development of a genetically modified adenovirus that does not initiate metastasis is of particular importance to the study of cancer treatments and consequently to the field of Biology. It could help Biology scholars to help their understanding of how cancer tumor cells act and how to battle it in ways that could be developed more to further lessen the effect of oncolytic cells on other healthy tissues in different organism as Dr. Podhjacer’s group have also tested on animals that had reversed liver enzymes producing lesser toxins after receiving the
