Human glioblastomas are characterized with high mortality due to the resistance to clinical standard therapeutic practice. The purpose of this study is to characterize the Temozolomide-resistant (TMZ-R) and -sensitive (TMZ-S) clones for translational study. Our study found that high expression of methylguanine methyltransferase (MGMT) contributed to high mortality. Moreover, TMZ-resistant clone highly expressed MGMT. We further characterize the gene expression profile between TMZ-R and TMZ-S clones using gene array. Next, we found novel method to re-sensitize the TMZ-R human glioblastomas. Taken together, our findings provide the future clinical trial perspectives in improvement of survival of human glioblastomas.
