Project description:Murine M7 leukemia derived from retroviral insertional mutagenesis of Gata1s fetal progenitors
| PRJNA122691 | ENA
Project description:In this project, we studied a mouse model of human Down Syndrome (DS) megakaryocytic leukemia involving mutations in the GATA1 transcription factor (called GATA1s mutation). The model was generated through retroviral insertional mutagenesis in Gata1s mutant fetal liver progenitors. In this study, we analyzed the dependency of these leukemic cells on the Gata1s mutant protein. Here we report Gata1s mutant leukemic cells were dependent on this mutant protein. Introduction of the full-length Gata1 protein to these cells led to their reduced proliferation and increased differentiation along the megakaryocytic lineage.

Introduction of the full-length Gata1 protein to these cells led to their reduced proliferation and increased differentiation along the megakaryocytic lineage. We transduced leukemic cells with Gata1/estrogen receptor fusion cDNA (Gata1-ER) and generated stable cell lines. Addition of beta-estradiol to culture medium led to activation of the full-length Gata1 protein in synchronized leukemic cells. Gene expression profiles were collected at multiple time points.

Project description:The goal of this study is to derive a mouse model of human Down Syndrome (DS) megakaryocytic leukemia involving mutations in the hematopoietic transcription factor, GATA1 (called GATA1s mutation). We achieved this through transduction of Gata1s mutant fetal progenitors by MSCV-based retrovirus expressing a GFP marker, followed by in vitro selection (for immortalized cell lines), and then in vivo selection (for transformed cell lines) through transplantation. Here we report one such cell line [T6(6)] that gives rise to megakaryocytic leukemia (M7 leukemia) upon transplantation.

Here we report one such cell line [T6(6)] that gives rise to megakaryocytic leukemia (M7 leukemia) upon transplantation. Since the leukemic cells were retrovirally tagged with a GFP reporter, we sorted GFP+ leukemic blasts and generated their expression profiles by microarray.

We show knockdown of IGF1R in these cells leads to their reduced proliferation. IGF1R was knocked down in these cells using a tet-regulatable shRNA-based lentiviral system. Cells infected with the empty vector or those infected with shRNA construct against IGF1R but in the absence of Doxycycline were used as controls. The latter cells in the presence of Doxycycline exhibited reduced IGF1R at the RNA level.
