Figure 4From: Sensitivity to cisplatin in primary cell lines derived from human glioma correlates with levels of EGR-1 expressionEGR-1 expression by immunoistochemistry and response to anticancer drugs in primary cell lines of glioma. A) BMR-76 primary cell line showing EGR-1 positive cells with different levels of positivity detected by an anti-EGR-1 polyclonal antibody. B) FLS-10, a mostly negative primary cell line. C) Relationship between the percentage of EGR-1 positive cells measured by immunoistochemistry and the EC50 response to cisplatin, measured with the clonogenic assay. D) Relationship between the clonogenic index and the percentage of EGR-1 positive cells measured by immunocytochemistry, in primary cell lines of human glioma carrying wild type copies of p53, p16/INK4a and MDM2 genes. This index is a global measure of the sensitivity to the six anticancer drugs measured with the clonogenic assay.Back to article page
