The stress kinase MKK7 couples oncogenic stress to p53 stability and tumor suppression

ABSTRACT: Transcriptional profiling of control and MKK7-deficient primary mouse pneumocytes after oncogenic KRasG12 induction Two-condition experiment, MKK7 proficient vs. MKK7 deficient pneumocytes. 3 Biological replicates: 3 control, 3 knock out, independently grown and harvested. 3 technical replicates per array (each sample was hybridized to 3 in-house arrays (47MM, 51MM and 46MM - see HybridisationInfo.xls) for a total of 54 hybridizations).

Most preneoplastic lesions are quiescent and do not progress to form overt tumors. It has been proposed that oncogenic stress activates the DNA damage response and the key tumor suppressor p53, which prohibits tumor growth. However, the molecular pathways by which cells sense a premalignant state in vivo are largely unknown. Here we report that tissue-specific inactivation of the stress signaling kinase MKK7 in KRas(G12D)-driven lung carcinomas and NeuT-driven mammary tumors markedly accelerates ...[more]

Project description:a salmonid microarray was used to characterize environmentally-regulated shifts in gene expression between ocean and river habitats in gill and liver tissues of wild migrating adult Pacific sockeye salmon (Oncorhynchus nerka). To correlate gene expression with survival, non-lethal biopsy sampling of gill tissue and microarray-based profiling was combined with biotelemetry and genetic stock identification so that transcriptomic profiles could be compared between fish reaching spawning grounds and presumed mortalities. Fish were captured fish at two marine sampling sites, one within Johnstone Strait (JS), BC. Canada and one within Juan De Fuca Strait (JDFS), BC Canada. Ocean sites were contrasted to fish sampled within the Fraser River at Whonnock (W), BC, Canada. Gill and liver tissues were dissected at each of these sites. Non-lethal biopsy sampling was performed on migrating sockeye salmon intercepted within the Fraser River at Mission, BC, Canada and genetically-based stock ID was used to determine the stock-specific spawning grounds for each fish, giving an intended end-point of migration for each of the stocks investigated in this study.Gene expression levels were determined by comparing the amount of mRNA transcript in the experimental samples relative to a reference sample. A total of 123 microarrays were used to generate the dataset, corresponding to individual hybridizations of both gill and liver samples collected from JS (gill n=14; liver n=15), JDFS (gill n=15; liver n=13), W (gill n=11; liver n=10), and biopsy sampled gill tissue collected at Mission (n=45).Total RNA was amplified (1 round) with MessageAmpTMII-96 kit (Ambion, TX, USA), and reverse transcribed to cDNA before labelling with ALEXA dyes using the Invitrogen Indirect Labelling Kit. The reference contained the combined aRNA of all individuals used in the experiment, excluding bioposy sampled fish. Individual samples were labelled with Alexa 555 and the reference control with Alexa 647, and no dye swaps were perfromed.
