Transcription profiling of human-melanoma derived cell lines response to chemotherapy

ABSTRACT: To identify patterns of gene expression that correlate with response to treatment with either melphalan or temozolomide we measured both gene expression using microarray genechips and response to drug using a standard in vitro cell proliferation assay. Senstivity to melphalan was measured 48hrs after drug treatment while sensitivity to temozolomide was measured 12 days after drug treatment. Experiment Overall Design: For each of the 50 melanoma-derived cell lines, 1 flask of cells was grown to 80% confluence and harvested for RNA isolation. Cells were lysed in buffer with 1% β-mercaptoethanol and RNA isolated using Qiagen RNeasy-plus RNA isolation kit which included a step to eliminate genomic DNA. RNA concentration was measured and quality assessed using the NanoDrop ND100 spectrophot
