Project description:Atypical teratoid/rhabdoid tumors (ATRT) are known for their heterogeneity concerning pathophysiology and outcome. However, predictive factors within distinct subgroups still need to be uncovered. Using multiplex immunofluorescent staining and singe-cell RNA sequencing we unraveled distinct compositions of the immunological tumor microenvironment (TME) across ATRT subgroups. CD68+ cells predominantly infiltrate ATRT-SHH and ATRT-MYC and are a negative prognostic factor for patients’ survival. Within the murine ATRT-MYC and ATRT-SHH TME, Cd68+ macrophages are core to intercellular communication with tumor cells. In ATRT-MYC distinct tumor cell phenotypes express macrophage marker genes. These cells are involved in the acquisition of chemotherapy resistance in our relapse xenograft mouse model. In conclusion, the tumor cell-macrophage interaction contributes to ATRT-MYC heterogeneity and tumor recurrence.

Project description:Atypical teratoid/rhabdoid tumor (ATRT) is one of the most common brain tumors in infants. Although the prognosis of ATRT patients is poor, some patients respond favorably to current treatments, suggesting molecular inter-tumor heterogeneity. To investigate this further, we genetically and epigenetically analyzed a large series of human ATRTs. Three distinct molecular subgroups of ATRTs, associated with differences in demographics, tumor location, and type of SMARCB1 alterations, were identified. Whole-genome DNA and RNA sequencing found no recurrent mutations in addition to SMARCB1 that would explain the differences between subgroups. Whole-genome bisulfite sequencing and H3K27Ac chromatin-immunoprecipitation sequencing of primary tumors, however, revealed clear differences, leading to the identification of subgroup-specific regulatory networks and potential therapeutic targets. 49 ATRT samples were selected for RNA extraction and hybridization on Affymetrix Affymetrix Human Genome U133 Plus 2.0 Arrays. ---------------------------------------- This submission consists of the expression data for 49 of 170 samples only

Project description:Taxanes are widely used in chemotherapy, but intrinsic and acquired resistance limit the clinical outcomes. Studies showed tumor interaction with suppressive macrophages plays a key role in taxane resistance, yet therapeutic strategies that deplete or repolarize macrophages are challenging. Here we uncovered a novel tumor-macrophage interaction via Notch2-Jag1 justacrine signaling that can be targeted to sensitize paclitaxel response without affecting the broad macrophage functions. Using translatome profiling, we identified Notch2 upregulation during taxol-induced prolonged mitosis. Notch2 was subsequently activated in the post-mitotic G1 phase by Jag1 expressed on neighboring macrophages, which promoted tumor cell survival by upregulating p38 and anti-apoptotic proteins. Notch2 also upregulated cytokines that further recruited Jag1-expressing macrophages. By targeting this Notch2-Jag1 interaction with a pan-Notch inhibitor, RO4929097, taxol resistance was significantly attenuated in multiple mouse tumor models. Our results point to combining Notch inhibitor with taxane as an effective strategy to selectively disrupt tumor-macrophage interaction underlying chemoresistance.

Project description:The tumor necrosis factor induced protein 8 (TNFAIP8), a novel anti-apoptotic molecule, has been implicated in chemoresistance of several types of neoplasms, but its role in AML remains to be elucidated. In this study, upregulated TNFAIP8 expression was found in human AML patients and cell lines. E74 like ETS transcription factor 1 (ELF1) was identified to contribute to its aberrant expression. Forced expression of TNFAIP8 protected cells from apoptosis induced by chemotherapeutic agents and increased drug resistance. Importantly, the leukemia-promoting action of TNFAIP8 was mediated by sustaining activity of the extracellular signal-regulated kinase (ERK) signaling pathway through an interaction with Rac family small GTPase 1 (Rac1). In vivo experiments showed that TNFAIP8 suppression lowered leukemia infiltration and improved survival. Taken together, our data provide a molecular basis for the role of TNFAIP8 in chemoresistance and progression of AML and highlight the unique function of TNFAIP8 as an attractive therapeutic target.
