Project description:Transforming growth factor beta receptor 2 (Tgfbr2) was predicted as a causal gene for abdominal using a novel statistical method named LCMS (Schadt et al., 2005, Nature Genetics). In order to validate this prediction, we profiled the liver tissues of Tgfbr2 heterozygous knockout mice (Tgfbr2+/-) and their littermate wild-type (wt) controls to examine the gene expression signature as well as pathways/networks resulting from the single gene perturbation. 6 Tgfbr2+/- mice and 4 wt controls were profiled. Reference pool included RNA extracted from the liver of 6 wt control mice. Dye-swap was involved in the profiling.

Project description:A major task in dissecting the genetics of complex traits is to identify causal genes for disease phenotypes. We previously developed a method to infer causal relationships among genes through the integration of DNA variation, gene transcription, and phenotypic information. Here we validated our method through the characterization of transgenic and knockout mouse models of candidate genes that were predicted to be causal for abdominal obesity. Perturbation of eight out of the nine genes, with Gas7, Me1 and Gpx3 being novel, resulted in significant changes in obesity related traits. Liver expression signatures revealed alterations in common metabolic pathways and networks contributing to abdominal obesity and overlapped with a macrophage-enriched metabolic network module that is highly associated with metabolic traits in mice and humans. Integration of gene expression in the design and analysis of traditional F2 intercross studies allows high confidence prediction of causal genes, and identification of involved pathways and networks.

Project description:Lung mesenchymal knockout of transforming growth factor, beta receptor II (Tgfbr2) will lead to lung malformation, including impaired lung branching and cystic lesion. In order to understand the underlying mechanisms, total RNA of wild type and mesenchymal Tgfbr2 knockout lungs were isolated and sequenced using the next-generation RNA sequencing technique.

Project description:Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer. Transforming growth factor beta (TGF-β) is highly expressed in the liver tumor microenvironment and is known to inhibit immune cell activity. Here, we used human iPSCs to produce natural killer (NK) cells engineered to mediate improved anti-HCC activity. Specifically, we produced iPSC-NK cells with either knock out TGF-β receptor 2 (TGFBR2-KO) or expression of a dominant negative (DN) form of the TGF-β receptor 2 (TGFBR2-DN) combined with CARs that target either GPC3 or AFP. The TGFBR2-KO and TGFBR2-DN iPSC-NK cells are resistant to TGF-β inhibition and improved anti-HCC activity. However, expression of anti-HCC CARs on iPSC-NK cells did not lead to effective anti-HCC activity unless there was also inhibition of TGF-b activity. Our findings demonstrate that TGF-β signaling blockade is required for effective NK cell function against HCC and potentially other malignancies which express high levels of TGF-β.

Project description:Mutations in TGFBR2, a component of the transforming growth factor (TGF)-β signaling pathway, occur in high-frequency microsatellite instability (MSI-H) colorectal cancer (CRC). In mouse models, Tgfbr2 inactivation in the intestinal epithelium accelerates the development of malignant intestinal tumors in combination with disruption of the Wnt-β-catenin pathway. However, no studies have further identified the genes influenced by TGFBR2 inactivation following disruption of the Wnt-β-catenin pathway. We previously described CDX2P-G19Cre;Apcflox/flox mice, which is stochastically null for Apc in the colon epithelium. In this study, we generated CDX2P-G19Cre;Apcflox/flox;Tgfbr2flox/flox mice, with simultaneous loss of Apc and Tgfbr2. These mice developed tumors, including adenocarcinoma in the proximal colon. We compared gene expression profiles between tumors of the two types of mice using microarray analysis.

Project description:Heterogeneous astrocyte populations are defined by diversity in cellular environment, progenitor identity or function. Yet, little is known about the extent of the heterogeneity and how this diversity is acquired during development. We used SILAC and quantitative proteomics to characterise primary murine telencephalic progenitor cells from FOXG1 (forkhead box G1)-cre driven Tgfbr2 (transforming growth factor beta receptor 2) knockout mice and identified differential protein expression of the astrocyte proteins GFAP (glial fibrillary acidic protein) and MFGE8 (milk fat globule-EGF factor 8). Biochemical and histological investigations revealed distinct populations of astrocytes in the dorsal and ventral telencephalon marked by GFAP or MFGE8 protein expression. The two subtypes differed in their response to TGFβ-signalling. Impaired TGFβ-signalling affected numbers of GFAP-astrocytes in the ventral telencephalon. In contrast, TGFβ reduced MFGE8 expression in astrocytes deriving from both regions. Additionally, lineage tracing revealed that both GFAP and MFGE8 astrocyte subtypes derived partly from FOXG1-expressing neural precursor cells.

Project description:DNA mismatch repair-deficient colorectal tumors (CRC) frequently show coding microsatellite frameshift mutations in the MSI tumor driver Transforming Growth Factor Beta Receptor Type 2 (TGFBR2) leading to cellular alteration of MSI tumor cells [Lee, J., Warnken, U., Schnölzer, M., Gebert, J. & Kopitz, J. (2015) Protein Sci. 24, 1686-94; Lee, J., Ballikaya, S., Schonig, K., Ball, C. R., Glimm, H., Kopitz, J. & Gebert, J. (2013) PloS one. 8, e57074]. Whether this receptor expression in MSI tumor cells also impacts the exosomal proteomic cargo of these cells is still unknown.

Project description:Microsatellite unstable (MSI) colorectal cancers (CRCs) are characterized by Transforming Growth Factor Beta Receptor Type 2 (TGFBR2) deficiency. TGFBR2-deficient CRCs present altered target gene and protein expression. Such cellular alterations modulate the content of CRC-derived extracellular vesicles (EVs). EVs function as couriers of proteins, nucleic acids, and lipids in intercellular communication. At a qualitative level, we have previously shown that TGFBR2 deficiency can cause overall alterations in the EV protein content. To deepen the basic understanding of altered protein dynamics, this work aimed to quantify EV protein signatures in a TGFBR2-dependent manner. Using a SILAC approach for mass spectrometry-based quantification, 48 proteins that appeared to be regulated by cellular TGFBR2 expression were identified in MSI-derived EVs. TGFBR2-primed EVs were enriched in proteasome-associated proteins, whereas TGFBR2 deficiency led to upregulation of EV proteins related to the extracellular matrix and nucleosome. Altogether, the present study emphasizes the general overlap of proteins between EVs and their parental CRC cells and highlights the pathological role of the MSI tumor driver mutation affecting TGFBR2 by altering protein landscapes of EVs. From a clinical perspective, TGFBR2-regulated quantitative differences of protein expression in EVs might nominate novel biomarkers for liquid biopsy-based MSI typing in the future.
