Project description:Expression data from knockdown of BACH1 in HEK 293T cells
| PRJNA143129 | ENA
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 performed knock-down of BACH1 in HEK 293T cells using three independent types of small interfering RNAs followed by transcriptome profiling using microarrays.

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.

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 performed knock-down of BACH1 in HEK 293T cells using three independent types of small interfering RNAs followed by transcriptome profiling using microarrays. Knockdown of BACH1 in HEK 293T cells was carried out with three different types of siRNA molecules (esiRNA = e, siRNA1 SI00309876 from Qiagen = q and Stealth siRNA2 HSS100910 from Invitrogen = s), followed by RNA extraction after 24h and 72h of knockdown and hybridization on Affymetrix microarrays. For each siRNA type, we performed the experiments in triplicates, with four control replicates (mock transfections without siRNA) at 24h and three control replicates at 72h, resulting in nine samples and four controls at 24h and nine samples and three controls at 72h. Samples at 24h of knockdown: e_1_24, e_2_24, e_3_24, q_1_24, q_2_24, q_3_24, s_1_24, s_2_24, s_3_24. Controls at 24h: m_1_24, m_2_24, m_3_24, m_4_72. Samples at 72h of knockdown: e_1_72, e_2_72, e_3_72, q_1_72, q_2_72, q_3_72, s_1_72, s_2_72, s_3_72. Controls at 72h: m_1_72, m_2_72, m_3_72. REPEATS: biological replicate: BACH1_e_1_24, BACH1_e_2_24, BACH1_e_3_24 biological replicate: BACH1_q_1_24, BACH1_q_2_24, BACH1_q_3_24 biological replicate: BACH1_s_1_24, BACH1_s_2_24, BACH1_s_3_24 biological replicate: BACH1_m_1_24, BACH1_m_2_24, BACH1_m_3_24, BACH1_m_4_24 biological replicate: BACH1_e_1_72, BACH1_e_2_72, BACH1_e_3_72 biological replicate: BACH1_q_1_72, BACH1_q_2_72, BACH1_q_3_72 biological replicate: BACH1_s_1_72, BACH1_s_2_72, BACH1_s_3_72 biological replicate: BACH1_m_1_72, BACH1_m_2_72, BACH1_m_3_72

Project description:Methylome data obtained from human embryonic kindey (HEK)-293T cells expressing a GFP (293T-GFP) or a truncated form of Arabidopsis DEMETER (DME) 5-methylcytosine (5mC) DNA glycosylase (293T-DMEΔ) analyzed on a Human Methylation 450K BeadChip platform (Illumina). These methylation array data revealed genome-wide DNA methylation patterns of the 293T-GFP cells (without direct 5mC excision activity) and 293T-DMEΔ cells (with artificially implemented direct 5mC excision activity).

Project description:4C procedure was used for analysis of genomic contacts of rDNA units in HEK 293T cells. The primers for 4C were selected inside IGS. Our data indicate that mostly rDNA units exhibit close proximity with pericentromeric regions in different chromosomes. We also detected the contacts within a rDNA unit and between rDNA units. Examination of rDNA genome-wide contacts in HEK 293T cells using 4C approach.
