چکیده
This year, 30 million acres of the corn, cotton, and potatoes planted in the United States will have been genetically engineered to produce an endotoxin normally found in the microbe Bacillus thuringiensis (Bt), a self-contained pesticide that will be toxic only to target insects. Transgenic pest-resistant crops are a cost-effective alternative to chemical pesticides, and may offer a way to help feed the world's growing population with minimal environmental impact.

متن کاملAbrogation of interferon-induced resistance to interferon-activated major histocompatibility complex-unrestricted killers by treatment of a melanoma cell line with 5-fluorouracil.
Advanced cancer responds clinically to combined therapy with recombinant interferon-alpha and 5-fluorouracil. Although the two agents may interact in the biosynthetic pathway for thymidine, we investigated, as an alternative mechanism, the regulation of susceptibility of the A375 human melanoma to natural killers activated by interferon. A375 were preincubated with 5-fluorouracil, interferon, o...

Advanced cancer responds clinically to combined therapy with recom binant interferon-a and 5-fluorouracil. Although the two agents may interact in the biosynthetic pathway for thymidine, we investigated, as an alternative mechanism, the regulation of susceptibility of the A375 human melanoma to natural killers activated by Interferon. A375 were preincubated with 5-fluorouracil, Interferon, or b...
متن کاملNatural Killers Are Made Not Born: How to Exploit NK Cells in Lung Malignancies
In recent years, progress has been made in the characterization of natural killer (NK) cells in lung malignancies, and we have now gained a better understanding of the frequency, localization, phenotype, and functional status of NK cells infiltrating these tumors. NK cell subset recruited in lung cancer is mainly capable of producing relevant cytokines rather than exerting direct cancer cell ki...
