Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Background: Malignant peripheral nerve sheath tumors (MPNST) are soft-tissue sarcomas that can arise either sporadically or in association with neurofibromatosis type 1 (NF1). These aggressive malignancies confer poor survival, with no effective therapy available.

Description
TREX2 is a keratinocyte specific 3’-deoxyribonuclease that participates in the maintenance of skin homeostasis upon damage. This transcriptome analysis identified multiple genes and pathways deregulated by TREX2 loss in the IMQ-induced psoriasis-like model in mouse skin. Overall design: mRNA sequencing of 5 biological replicates of skin from wild-type mice treated with Imiquimod and 6 of Trex2 knockout mice treated with Imiquimod

Description
Inhibitors of the mechanistic target of rapamycin (mTOR) are currently used to treat advanced metastatic breast cancer. However, whether an aggressive phenotype is sustained through adaptation or resistance to mTOR inhibition remains unknown. Here, complementary studies in human tumors, cancer models and cell lines reveal transcriptional reprogramming that supports metastasis in response to mTOR inhibition. This cancer feature is driven by EVI1 and SOX9. EVI1 functionally cooperates with and positively regulates SOX9, and promotes the transcriptional upregulation of key mTOR pathway components (REHB and RAPTOR) and of lung metastasis mediators (FSCN1 and SPARC). The expression of EVI1 and SOX9 is associated with stem cell-like and metastasis signatures, and their depletion impairs the metastatic potential of breast cancer cells. These results establish the mechanistic link between resistance to mTOR inhibition and cancer metastatic potential, thus enhancing our understanding of mTOR targeting failure.
