Dataset link MEK inhibition exhibits efficacy in human and mouse neurofibromatosis tumors, despite transcriptional feedback onto ERK.

Experimental Protocol


83 microarrays: Mouse control (15), Mouse neurofibroma (15), Mouse MPNST (18); Human nerve (3), Human neurofibroma (26), Human MPNST (6) We used the same human tumor samples as in series GSE14038 (dNF, pNF and MPNST). However, instead of referencing gene expression changes to the normal human Schwann cell samples (NHSC) as we did in series GSE14038, we generated three (new) normal nerve samples (samples jan-N1-3) and referenced gene expression changes to those samples. Moreover, the analysis of series GSE14038 evaluated changes in expression between NHSC, benign tumor subtypes (dNF and pNF), and malignant tumors (MPNST), while our present submission evaluated changes between normal nerve, benign tumors (combined dNF and pNF),and malignant tumors (MPNST). The Series supplementary 'merged_data.txt' file contains the data for 9,891 transcripts that were statistically different in at least one of the two species and present in both mouse and human data sets.
