Temporal resolution of gene derepression and proteome changes upon PROTAC-mediated degradation of BCL11A protein in erythroid cells

Project description:Reactivation of fetal hemoglobin expression by down-regulation of BCL11A is a promising treatment of -hemoglobinopathies. A detailed understanding of BCL11A-mediated repression of -globin gene (HBG1/2) transcription is lacking, as studies to date used perturbations by shRNA or CRISPR/Cas9 gene editing. We leveraged the dTAG PROTAC platform to acutely deplete BCL11A protein in erythroid cells and examined consequences by PRO-seq, proteomics, chromatin accessibility, and histone profiling. Among ≤ 31 genes repressed by BCL11A, HBG1/2 and HBZ show the most abundant and progressive changes in transcription and chromatin accessibility upon BCL11A loss. Transcriptional changes at HBG1/2 were detected in < 2h. Robust HBG1/2 reactivation upon acute BCL11A-depletion occurred without loss of promoter 5methylcytosine (5mC). Using targeted protein degradation, we establish a hierarchy of gene reactivation at BCL11A targets, in which nascent transcription is followed by increased chromatin accessibility, and both are uncoupled from promoter DNA methylation at the HBG1/2 loci.

Identification of BCL11A targets by CHIP Seq

Project description:We have recently identified BCL11A as a key regulator of mammary stem (MaSC) and progenitor cells. Deletion of BCL11A in MaSC leads to loss of ability of those cells to engraft a cleared mammary fatpad. This biological function of BCL11A correlates with its overexpression in basal breast cancers which are thought to arise from stem and progenitor subtypes. Basal breast cancer cell lines where BCL11A is knocked down using shRNA failed to develop tumours in xenograft transplantations in mice. Therefore, BCL11A is potentially a novel target for breast cancer treatment. Microarray analysis has identified potential gene targets for BCL11A however, it is not known if these targets are directly regulated by BCL11A at the transcription level. We would like to perform CHIP-SEQ analysis on a mammary cell line using BCL11A antibody under two conditions (normal expression and overexpression of BCL11A).This data is part of a pre-publication release.

Dendritic cell fate is determined by BCL11A

Project description:The plasmacytoid dendritic cell (pDC) is vital to the coordinated action of innate and adaptive immunity. pDC development has not been unequivocally traced, nor has its transcriptional regulatory network been fully clarified. Here we confirm an essential requirement for the BCL11A transcription factor in fetal pDC development, and demonstrate this lineage-specific requirement in the adult organism. Furthermore, we identify BCL11A gene targets and provide a molecular mechanism for its action in pDC commitment. Embryonic germ-line deletion of Bcl11a revealed an absolute cellular, molecular, and functional absence of pDCs in fetal mice. In adults, deletion of Bcl11a in hematopoietic stem cells resulted in perturbed yet continued generation of progenitors, loss of downstream pDC and B-cell lineages, and persisting myeloid, conventional dendritic, and T-cell lineages. Challenge with virus resulted in a marked reduction of antiviral response in conditionally deleted adults. Genome-wide analyses of BCL11A DNA binding and expression revealed that BCL11A regulates transcription of E2-2 and other pDC differentiation modulators, including ID2 and MTG16. Our results identify BCL11A as an essential, lineage- specific factor that regulates pDC development, supporting a model wherein differentiation into pDCs represents a primed "default" pathway for common dendritic cell progenitors. Raji cells were infected with retroviruses containing pXY-PURO (negative control vector) or pXY-BCL11A-XS. BJAB cells were infected with retroviruses containing pXY-PURO (negative control vector) or pXY-BCL11A-XL. Two arrays measured Raji BCL11A-XS expression and two arrays measured BJAB BCL11A-XL expression.
