Microglial metabolism mediated by BACH1 orchestrates astrogenesis during brain development

Project description:Purpose: To gain futher insight into how microglia-derived BACH1 regulates microglial metabolism and astrogenesis, RNA-seq was used to analyze the genome-wide changes resulting from isolated microglia of E16 microglial BACH1 conditional knock out mice and littermate wild-type. Methods: mRNA from E16 isolated microglia of Bach1fl/fl and Bach1cKO-Cx3 mice was extracted. Specifically, Agilent 2100 Bioanalyze was used to quality controlled and quantified. then, mRNA was converted to cDNA and bound the library. RNA-sequencing analysis was used by the Illumina HiSeq 2500 platform in Annoroad Genomics. Results: Approximately one thousand transcripts showed differential expression between the Bach1fl/fl and Bach1cKO-Cx3 mice brain microglia, with a fold change ≥3 and p value <0.05. Geneontology analysis of the downregulated genes were enriched in terms related to cell proliferation, glial cell differentiation and cell communication and upregulated genes were enriched in terms related to negative regulation of cell proliferation, negative regulation of astrocyte differentiation and glial cell fate commitment. These results reflected microglia BACH1 plays roles in cortex development. Conclusions: Microglia BACH1 RNA-seq would provide a overall understanding how microglia-derived BACH1regulates astrogenesis during brain development.

TANK binding kinase 1 induces transcription factor BACH1 to regulate iron metabolism in pancreatic cancer cells

Project description:BTB and CNC homology 1 (BACH1) represses the expression of genes involved in the metabolism of iron, heme and reactive oxygen species and promotes metastasis of various cancers including pancreatic ductal adenocarcinoma (PDAC). Knockdown of Tank binding kinase 1 (TBK1) led to reductions of BACH1 mRNA and protein amounts in AsPC-1 human PDAC cells. Gene expression analysis of PDAC cells with knockdown of TBK1 or BACH1 suggested the involvement of TBK1 and BACH1 in the regulation of iron homeostasis. Ferritin was increased upon BACH1 knockdown in AsPC-1 cells. Cytometry analysis showed that AsPC-1 cells with BACH1 knockout or knockdown contained lower labile iron than control cells, suggesting that BACH1 increased labile iron by repressing the expression of ferritin genes.

Genome-wide map of BACH1 binding in HEK 293T cells

Project description:BTB and CNC homology 1 (BACH1) is a heme-binding transcription factor repressing the transcription from a subset of MAF recognition elements (MAREs) at low intracellular heme levels. Upon heme binding, BACH1 is released from the MAREs, resulting in increased expression of antioxidant response genes. To systematically address the gene regulatory networks involving BACH1, we combined chromatin immunoprecipitation-sequencing (ChIP-seq) analysis of BACH1 target genes in HEK 293 cells with knock-down of BACH1 using three independent types of small interfering RNAs followed by transcriptome profiling using microarrays. The 59 BACH1 target genes identified by ChIP-seq were found highly enriched in genes showing expression changes after BACH1 knock-down, demonstrating the impact of BACH1 repression on transcription. In addition to known and new BACH1 targets involved in heme degradation (HMOX1, FTL, FTH1, ME1, SLC48A1) and redox regulation (GCLC, GCLM, SLC7A11), we also discovered BACH1 target genes effecting cell cycle and apoptosis pathways (ITPR2, CALM1, SQSTM1, TFE3, EWSR1, CDK6, BCL2L11, MAFG) as well as subcellular transport processes (CLSTN1, PSAP, MAPT, vault RNA). The newly identified impact of BACH1 on genes involved in neurodegenerative processes and proliferation provides an interesting basis for future dissection of BACH1-mediated gene repression in neurodegeneration and virus-induced cancerogenesis. Examination of BACH1 binding in HEK 293T cells by chromatin immunoprecipitation-sequencing (CHIP-seq) with input DNA as control.

BACH1 is a central regulator of glutathione metabolism, cellular necrosis and host resistance in Mycobacterium tuberculosis infection

Project description:Background. An exacerbated oxidative stress response can regulate cellular necrosis by triggering lipid peroxidation in an iron-dependent manner and this form of necrotic death has been implicated in Mycobacterium tuberculosis (Mtb) pathogenesis. Here we examined the role of Bach1, a transcription factor that represses a major set of antioxidant genes, in regulating host resistance to Mtb. We found that BACH1 expression is associated with and predicts active pulmonary tuberculosis in humans. In response to Mtb infection in vitro and in vivo, ablation of Bach1 increased the levels of glutathione as well as enhanced the expression of Gpx4, an enzyme that regulates lipid peroxidation. Consistent with these observations, Bach1-/- macrophages exhibited increased resistance to Mtb-induced cell death and infected Bach1-deficient mice displayed a striking reduction in bacterial loads as well as pulmonary necrosis and lipid peroxidation accompanied by enhanced survival. In addition, single-cell RNAseq analysis of the lungs of Mtb-infected Bach1-/- mice revealed an enrichment of genes associated with suppression of ferroptosis. Finally, deletion of Bach1 in B6.Sst1S mice, an inbred strain that exhibits the necrotic lung pathology similar to that seen in human TB, enhanced host resistance to Mtb while significantly reducing tissue necrosis. These findings identify Bach1 and its regulation of the oxidative stress response as an important modulator of cellular and tissue necrosis as well as host resistance in Mtb infection.

TREM2 regulates microglial lipid metabolism during aging in mice [RNA-Seq]

Project description:TREM2 is a microglial-specific gene implicated in late-onset Alzheimer's Disease (AD). Recent studies have identified that Trem2-deficient mice exhibit transcriptional changes in microglial gene expression that minimize the upregulation of lipid metabolism and lysosomal genes in AD disease models. We detect similiarly attenuated expression of lipid metabolism genes in microglia isolated from brains of aged Trem2 knockout mice.

TREM2 regulates microglial cholesterol metabolism upon chronic phagocytic challenge [bulk RNA-seq]

Project description:TREM2 is a microglial-specific gene implicated in late-onset Alzheimer's Disease (AD). Recent studies have identified that Trem2-deficient mice exhibit transcriptional changes in microglial gene expression that minimize the upregulation of lipid metabolism and lysosomal genes in AD disease models. We find that chronic phagocytic challenge from demyelination generates similiarly attenuated expression of lysosomal and lipid metabolism genes in microglia isolated from Trem2 knockout mouse brain.

BACH1 as a master regulator gene in vascular cells during aging

Project description:We identify transcription factor BACH1 as a master regulator in vascular cells during aging. BACH1 is upregulated in the aorta of old mice. We find BACH1 is located on open chromatin and BACH1 binds to CDKN1A gene enhancer and activates its transcription in endothelial cells. Finally, BACH1 aggravates endothelial cell senescence under oxidative stress. Thus, these findings demonstrate a crucial regulatory role of BACH1 in vascular aging.
