Project description:Long noncoding RNAs (lncRNAs) are transcripts longer than 200 nucleotides located within the intergenic stretches or overlapping antisense transcripts of protein coding genes. LncRNAs are involved in numerous biological roles including imprinting, epigenetic regulation, apoptosis and cell-cycle. To determine whether lncRNAs are associated with clinical features and recurrent mutations in older patients (aged ≥60 years) with cytogenetically normal (CN) acute myeloid leukemia (AML), we evaluated lncRNA expression in 148 untreated older CN-AML cases using a custom microarray platform.

Project description:This study aimed to identify whether c-Myc could facilitate prediction of "7+3" induction failure in de novo acute myeloid leukaemia (AML) with high-risk cytogenetics. Seventy-five untreated de novo AML patients who completed the "7+3" induction therapy were enrolled (24 patients from a prospective cohort; 51 patients from a retrospective cohort) and stratified into complete remission (CR) and non-CR groups. Myc-associated molecular signature between the CR and non-CR groups in the prospective cohort was compared after gene set enrichment analysis. c-Myc protein expression was assessed via immunohistochemical staining. A high c-Myc-immunopositivity was defined when ≥ 40% of bone marrow myeloblasts were c-Myc (+). Our results revealed that AML patients who did not achieve CR by the "7+3" induction therapy had a higher Myc gene expression than those that achieved CR (p=0.047). Myc gene expression was positively correlated with c-Myc protein expression (p=0.014). Although the non-CR group did not have more c-Myc protein expression compared to that in the CR group (p=0.151), combination of high c-Myc-immunopositivity and high-risk cytogenetics increased the probability of "7+3" induction failure compared to that in high-risk cytogenetics alone. Induction strategies other than “7+3” might be a solution for de novo patients with high c-Myc-immunopositivity and high-risk cytogenetics.

We analyzed 148 older cytogenetically normal(CN)-AML patients samples using a custom microarray platform and describe the expression of lncRNAs among the AML samples.

Project description:Epigenetic therapy, using hypomethylating agents (HMA), is known to be effective in the treatment of high-risk myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) patients who are not suitable for intensive chemotherapy or allogeneic stem cell transplantation. However, response rates to HMA are low and there is an unmet need in finding prognostic and predictive biomarkers of treatment response. We performed global methylation analysis of 75 patients with high risk MDS and secondary AML (sAML) who were included in CETLAM MDS-09 protocol, in which patients received HMA or intensive treatment according to age, comorbidities and cytogenetics. At diagnosis, no global methylation pattern allowed us to differentiate patients according to the cytological subtype, cytogenetics or treatment response. But we found a methylation signature defined by 200 probes, which allowed us to distinguish between responding and non-responding patients to azacitidine (AZA) treatment. Studying follow-up samples, we have confirmed that AZA decreases global DNA methylation, but in our cohort the degree of methylation decrease did not correlate with the type of response. The methylation signature detected at diagnosis was not useful in treated samples to determine a methylation pattern predictive of progression or relapse. In conclusion, altered DNA methylation patterns at diagnosis, in a subset of determined CpGs, may serve as biomarker for predicting AZA response.

Project description:The t(8;21) Acute Myeloid Leukaemia (AML) Kasumi-1cell line with N822K KIT mutation, is a model system for leukemogenesis. As AML initiating cells reside in the CD34+CD38– fraction, we addressed the refined cytogenomic characterization and miRNA expression of Kasumi-1 cell line and its FACS-sorted subpopulations focussing on this compartment. By conventional cytogenetics, Spectral Karyotyping and array-CGH the cytogenomic profile of Kasumi-1 cells evidenced only subtle regions differentially represented in CD34+CD38– cells.

Project description:Acute myeloid leukemia is a clinically and genetically heterogenous disease characterized by bone marrow infiltration with immature leukemic blasts that cause bone marrow failure. Patient age, comorbidities and genomic disease characteristics have a profound impact on patient outcome. Here, we present an integrated Multi-Omics analysis of protein and gene expression as well as cytogenetics and mutations to capture the rewiring of intracellular protein networks that is most likely caused by genomic aberrations. Because protein networks are downstream of genomic aberrations, we hypothesized that our Multi-Omics approach may add to the current AML classification by identifying proteomic AML subtypes with specific clinical and molecular features that could identify therapeutic vulnerabilities and aid in the identification of predictive biomarkers.

Project description:Although clinical features, cytogenetics, and mutations are widely used to predict prognosis in patients with acute myeloid leukemia (AML), further refinement of risk stratification is necessary for optimal treatment, especially in cytogenetically normal (CN) patients. We sought to generate a simple gene expression signature as a predictor of clinical outcome through analyzing the mRNA arrays of de novo CN-AML patients. Among 43 treatment response-related genes, expression of 11 genes was significantly associated with overall survival (OS) in univariate Cox regression analysis in 104 patients who received standard intensive chemotherapy. We integrated the z-transformed expression levels of these 11 genes to generate a risk scoring system. Higher risk scores were significantly associated with shorter OS (median 17.0 months vs. not reached, P<0.001) in ours and 3 other validation cohorts. In conclusion, we developed a simple mRNA expression signature for prognostication in CN-AML patients. This prognostic biomarker will help refine the treatment strategies for this group of patients.
