Geneticist:
Today, mas advanced na ang technology sa pagdetect at pagtreat ng mga sakit tulad ng sa kalagayan mo. May mga DNA tests na na puwedeng gawin para ma-diagnose agad ang disease at maagapan ang paggamot dito.
Tulad na lang ng sa cancer, may tinatawag na amniocentesis kung saan pinagbubuntis pa lang ang bata, malalaman na kung may kumplikasyon siya paglaki. Ginagamit ang DNA at iba pang proteins and enzymes mula sa amniotic fluid ng bata --
James: Ano po yung amniotic fluid?
Geneticist: Yun yung nourishing and protecting liquid na nagsu-surround sa baby habang nasa sinapupunan ng nanay... As I was saying, tinitingnan kung may mga defect ang DNA at iba pang proteins and enzymes ng bata. In this way, we are able to determine what diseases the child may have. Mayroon ding mga DNA sensors na nagdedetect ng genetic diseases. DNA sensors attach to the target DNA strands that are related to the disease and signal how much of it is present.
James: Yung lang po ba ang pwedeng genetic test para madetect ang mga disease?
Geneticist: Hindi naman. Para lang yun sa cancer. Marami pang mga tests para naman sa mga infectious diseases. Ginagamit and recombinant DNA technology para madetect ang specific DNA sequence ng isang disease-causing organism. Some infectious diseases that this technology is applied to are AIDS, tuberculosis and Lyme disease.
James: Doc, ano po bang puwedeng gawin para gumaling ako?
Geneticist: Marami na ring treatments na gumagamit ng DNA technology tulad ng tinatawag na gene therapy. Sa gene therapy, pinapalitan ang mutated gene (na nagcacause ng sakit) ng functional and therapeutic gene. Maari ring directly ina-alter ang mutated DNA para gawin itong functional. Actually, ang pinakaunang ginamitan ng recombinant DNA technology ay ang production ng insulin at human growth hormone. Kung yung insulin, primarily used for treating diabetes, human growth hormone is used for treating dwarfism.
James: At sa cancer...?
Geneticist: Para sa cancer, marami ring possible treatments. There is taxol that is used for treating ovarian cancer and tumor necrosis factor that is used as treatment for certain cancer cells. Yung widely used way to treat cancer is with interferons. Naturally occuring siya sa body pero through DNA technology, mas madali na siyang ibigay as medication sa mga patients. Interferons boost the immune system's anticancer function.
James: So, doc, ano po bang treatment ang makakatulong sakin?
Geneticist: Umm, James... Ikinalulungkot ko, pero... Uh... Your sickness has already developed into the advanced stages. I'm sorry, but there's nothing we can do... We can only-- biglang magiging unconscious si james
Geneticist: James?! James!!! calls ambulance
