Answer:
Yes
Explanation:
The goal of cancer gene therapy is to introduce new genetic material into target cells without toxicity to non-target tissues.The patient with recurrent or metastastic cancer is often considered incurable. A variety of chemotherapeutic agents has been used alone, and in combination, for the treatment of recurrent oral squamous cell carcinoma. However, chemotherapy is associated with well-known toxicities and has demonstrated no clear impact on survival in patients with recurrent oral cancer. Local and regional disease control is paramount, underscoring an urgent need for more effective therapies. Gene therapy has the potential to target cancer cells while sparing normal tissues. Such a strategy may be useful for recurrent disease as well as in the adjuvant setting (i.e., at the resected tumor margins).
Although gene therapy as a treatment for disease holds great promise, progress in developing effective clinical protocols has been slow. The problem lies in the development of safe and efficient gene-delivery systems. This review will evaluate the problems and the potential solutions in this new field of medicine.
The gradual development or replacement of one ecological community by another is called environment-replacement/takeover.
An organism that can make its own food is called an "Auto-troph". They maybe of two types:
1) Photo-Autotroph (Get source by sunlight)
2) Chemo-Autotroph (Get source by chemicals i.e., CH₄, NH₃ etc.)
Hope this helps!
Most carbon atoms are carbon-12, and these have 6 neutrons, but carbon-14 has 8 neutrons (2 extra), thus C-14 is considered an isotope of the element carbon.
