PolyA RNA-seq from retinoic acid-differentiated iPSCs treated with GSK343, 5-aza, or Combo (GSK343 & 5-aza)

ABSTRACT: Analysis of steady-state mRNA levels in induced pluripotent stem cells (iPSCs) differentiated for 5 days with retinoic acid (RA) and treated for final 48 hrs with GSK343 (EZH2 inhibitor), 5-azacytidine (5-aza, DNA methyltransferase inhibitor), or their combination (Combo).

mRNA profile of 5-aza-CR and 5-aza-CdR treated celllines

Project description:5-azacytidine and 5-aza-2'-deoxycytidine are both demethylating agents but they have shown different clinical efficiency. Since 5-azacytidine is incorporated into RNA it might have a different impact on the expression profile than 5-aza-2'-deoxycytidine. This study is designed to investigate the immediate action of the DNMTi on day 2 and the late heritable effects on day 8 after start of treatment.

Molecular response of AML blasts to Aza-treatment.

Project description:Azacytidine (Aza) treatment is effective in some patients with acute myeloid leukemia (AML). Clinical observations suggest that DNMT3A-mutant patients represent a subgroup of AML patients that responds particularly well to Aza-treatment. Data coming from a mouse model support this finding and we have already generated molecular data suggesting a molecular pathway involved in Aza-response in DNMT3A-mutant AML patients. We now aim to validate these findings in primary AML-blasts. To this end, we have FACS-sorted blasts from patients with AML prior to and under Aza-treatment and plan to correlate pre-treatment as well as on-treatment methylomes to clinical Aza-response.

SUMO pulldown proteomics Namalwa 5-Aza-2' deoxycytidine treatment

Project description:Combination therapies targeting malignancies aim to increase treatment efficacy and reduce toxicity. Hypomethylating drug 5-Aza-2’-deoxycytidine (5-Aza-2’) enhances transcription of tumor suppressor genes and induces replication errors via entrapment of DNMT1. Post-translational modification by SUMO plays major roles in the DNA damage response and is required for degradation of entrapped DNMT1. Here, we combine SUMOylation inhibitor TAK981 and DNA-hypomethylating agent 5-Aza-2’ to improve treatment of MYC driven hematopoietic malignancies, since MYC overexpressing tumors are sensitive to SUMOylation inhibition. We studied the classical MYC driven malignancy Burkitt lymphoma, as well as diffuse large B-cell lymphoma (DLBCL) with and without MYC translocation. SUMO inhibition prolonged the entrapment of DNMT1 to DNA, resulting in DNA damage. An increase in DNA damage was observed in cells co-treated with TAK981 and 5-Aza-2’. Both drugs synergized to reduce cell proliferation in vitro in a B cell lymphoma cell panel, including Burkitt lymphoma and DLBCL. In vivo experiments combining TAK981 (25 mg/kg) and 5-Aza-2’ (2.5 mg/kg) showed a significant reduction in outgrowth of Burkitt lymphoma in an orthotopic xenograft model. In contrast, single dosing of TAK981 was ineffective and single dosing of 5-Aza-2’ only led to a modest outgrowth reduction. TAK981 and 5-Aza-2’ synergize to reduce B cell Lymphoma outgrowth in vitro and in vivo. SUMOylation is a key-player in the repair of DNA damage, hence upon TAK981 treatment the repair of DNA damage induced by 5-Aza-2’ treatment is impaired. Our results demonstrate the potential of tailored combination of drugs, based on insight in molecular mechanisms, to improve the efficacy of cancer therapies.

LC-MSMS of the MHC-I immunopeptidome of AML cell line, THP-1

Project description:The hypomethylating agent 5-azacytidine (AZA) is the first-line induction therapy for AML patients unsuitable for intensive chemotherapy. The anti-tumor effect of AZA results in part from T-cell cytotoxic responses against MHC-I-associated peptides (MAPs) deriving from hypermethylated genomic regions such as cancer-testis antigens (CTAs), or endogenous retroelements (EREs). However, clear evidence supporting higher ERE MAPs presentation after AZA treatment in AML is lacking. Interestingly, we find that AZA-mediated DNMT2 inhibition leads to autophagy induction, which is responsible for mitigating ERE MAPs generation. To validate our findings, we examined the immunopeptidome of THP-1 cells treated with AZA combined with autophagy inhibitor, Spautin-1 or decitabine (DAC, non-DNMT2 inhibiting HMA) through a proteogenomic approach.

MCF7 cells gene expression change by inducing CpG demethylation using 5-Aza-2'-deoxycytidine (Aza)

Project description:Promoter methylation is able to induce downregulation of gene expression. 5-Aza-2'-deoxycytidine(Aza), methytransferase inhibitor, induce CpG demethylation. Here, 5-Aza-2'-deoxycytidine(Aza) is treated in a human breast cancer cell, MCF7, for detection of gene expression change. To analyze gene expression change by aza, control RNA isolated from MCF-7 was compared with RNA isolated from MCF-7 treated with 5uM and 10uM aza.
