| Research Abstract |
Epidermal growth factor receptor (EGFR) plays an important role in the progression of malignancy in gliomas. We studied the growth inhibition of the malignant glioma cell lines using an antisense EGFR oligonucleotide (normal phosphodister oligonucleotide) enveloped with Lipofectin^R (BRL) and we could have a good result. This time, we succeeded to develop the recombinant retro-virus vector expressiog EGFR antisense oligonucleotide, and we could inhibit the growth of the malignant glioma cell line using this retro-virus vector.
We analyzed structure of EGFR in 80 gliomas, and found that 40% of human malignant gliomas in vivo expressed aberrant EGFR.Furthermore, we have found two kinds of new aberrant EGFR.
