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
