제목 Effect of Conformation of Glucosylated Polyethylenimine as Gene Carrier on Cell Recognition in vitro and in vivo
초록 Cancer is a complex acquired disease that affects millions of individuals each year. Underlying the pathogenesis of cancer are a variety of molecular genetic abnormalities which can be inherited or environmentally induced and result in unregulated cell proliferation. Conventional treatment strategies used to treat cancer such as surgery, chemotherapy, and radiation have been only partially successful and new treatment options are critically needed. Gene therapy is currently being explored experimentally as an alternative or addition to established treatment options for malignant melanoma, leukemia, glioma, and others. The aim of this therapy is the introduction of a gene or cells resulting in the indirect elimination or direct killing of tumor cells. One of the most common and profound phenotypes of highly malignant tumors, known for more than seven decades, is their ability to metabolize glucose at high rates. This is a characteristic of highly malignant animal and human tumors including those derived from brain, colon, liver, lung, pancreas, stomach, and retina. For each, a close correlation exists among the degree of differentiation, growth rate, and glucose metabolism, where the most poorly differentiated tumors exhibit the fastest growth and the highest glycolytic rate.
Therefore, glucosylated polyethylenimine(PEI) was synthesized with varying substitution degree for tumor-targeting gene carrier and its potential was examined using lung cancerous cell line. Effect of conformation of glucosylated polyethylenimine as a gene carrier on cell recognition was checked.
