Insights into the manifestations, outcomes, and mechanisms of leukemogenesis in Down syndrome.

ABSTRACT: Children with Down syndrome (DS) show a spectrum of clinical anomalies, including cognitive impairment, cardiac malformations, and craniofacial dysmorphy. Moreover, hematologists have also noted that these children commonly show macrocytosis, abnormal platelet counts, and an increased incidence of transient myeloproliferative disease (TMD), acute megakaryocytic leukemia (AMKL), and acute lymphoid leukemia (ALL). In this review, we summarize the clinical manifestations and characteristics of these leukemias, provide an update on therapeutic strategies and patient outcomes, and discuss the most recent advances in DS-leukemia research. With the increased knowledge of the way in which trisomy 21 affects hematopoiesis and the specific genetic mutations that are found in DS-associated leukemias, we are well on our way toward designing improved strategies for treating both myeloid and lymphoid malignancies in this high-risk population.

Down syndrome and leukemia: insights into leukemogenesis and translational targets.

Project description:Children with Down syndrome (DS) have a significantly increased risk of childhood leukemia, in particular acute megakaryoblastic leukemia (AMKL) and acute lymphoblastic leukemia (DS-ALL). A pre-leukemia, called transient myeloproliferative disorder (TMD), characterised by a GATA binding protein 1 (GATA1) mutation, affects up to 30% of newborns with DS. In most cases, the pre-leukemia regresses spontaneously, however one-quarter of these children will go on to develop AMKL or myelodysplastic syndrome (MDS) . AMKL and MDS occurring in young children with DS and a GATA1 somatic mutation are collectively termed myeloid leukemia of Down syndrome (ML-DS). This model represents an important multi-step process of leukemogenesis, and further study is required to identify therapeutic targets to potentially prevent development of leukemia. DS-ALL is a high-risk leukemia and mutations in the JAK-STAT pathway are frequently observed. JAK inhibitors may improve outcome for this type of leukemia. Genetic and epigenetic studies have revealed likely candidate drivers involved in development of ML-DS and DS-ALL. Overall this review aims to identify potential impacts of new research on how we manage children with DS, pre-leukemia and leukemia.

Epigenetic changes in Down syndrome leukemogenesis

Project description:Acute megakaryoblastic leukemia (AMKL) is more frequently seen in Down syndrome patients, where it is often preceded by a transient myeloproliferative disorder (DS-TMD). The development of DS-TMD and DS-AMKL require not only the presence of the trisomy 21 but also that of GATA1 mutations. However, despite extensive studies into the genetics of DS-AMKL, not much is known about the epigenetic deregulation associated with this disease. In order to understand how epigenetic changes at the DNA methylation level contribute to DS leukemogenesis we performed DNA methylation profiling at different stages of development of this disease and analyzed the dynamics of epigenetic reprogramming. Early genome-wide epigenetic changes can be detected in trisomy 21 fetal liver mononuclear cells, even prior to the development of hematological abnormalities. These early changes are characterized by marked loss of DNA methylation at genes associated with regulation of key developmental processes. This first wave of aberrant DNA hypomethylation is followed by a second wave of epigenetic reprogramming detected in blast cells from DS-TMD and DS-AMKL, characterized by gains of methylation. This second wave of hypermethylation targets a distinct set of genes, preferentially affecting genes involved in hematopoiesis and regulation of cell growth and proliferation.

SERS-Based Evaluation of the DNA Methylation Pattern Associated With Progression in Clonal Leukemogenesis of Down Syndrome.

Project description:Here we show that surface-enhanced Raman scattering (SERS) analysis captures the relative hypomethylation of DNA from patients with acute leukemia associated with Down syndrome (AL-DS) compared with patients diagnosed with transient leukemia associated with Down syndrome (TL-DS), an information inferred from the area under the SERS band at 1005 cm-1 attributed to 5-methycytosine. The receiver operating characteristic (ROC) analysis of the area under the SERS band at 1005 cm-1 yielded an area under the curve (AUC) of 0.77 in differentiating between the AL-DS and TL-DS groups. In addition, we showed that DNA from patients with non-DS myeloproliferative neoplasm (non-DS-MPN) is hypomethylated compared to non-DS-AL, the area under the SERS band at 1005 cm-1 yielding an AUC of 0.78 in separating between non-DS-MPN and non-DS-AL. Overall, in this study, the area of the 1005 cm-1 DNA SERS marker band shows a stepwise decrease in DNA global methylation as cells progress from a pre-leukemia to a full-blown acute leukemia, highlighting thus the potential of SERS as an emerging method of analyzing the methylation landscape of DNA in the context of leukemia genesis and progression.

Molecular mechanisms of congenital heart disease in down syndrome.

Project description:Down syndrome (DS), as a typical genomic aneuploidy, is a common cause of various birth defects, among which is congenital heart disease (CHD). 40-60% neonates with DS have some kinds of CHD. However, the molecular pathogenic mechanisms of DS associated CHD are still not fully understood. This review summarizes available studies on DS associated CHD from seven aspects so as to provide a crucial and updated overview of what we known so far in this domain.

Mapping the Cellular Origin and Early Evolution of Down Syndrome Leukemogenesis [miRNA-Seq]

Project description:Children with Down syndrome have a 150-fold increased risk of developing myeloid leukemia. As Down syndrome leukemogenesis initiates during fetal development, we sought to characterize the cellular mechanisms of preleukemic initiation and leukemic progression using CRISPR/Cas9-mediated gene editing in human disomic and trisomic fetal liver hematopoietic cells and xenotransplantation. Compared to disomic fetal liver, trisomy 21 initiated atypical fetal hematopoiesis, in part through up-regulation of chromosome 21 miRNAs. GATA1 mutations caused transient preleukemia only when introduced into trisomy 21 long-term hematopoietic stem cells. By contrast, progression to leukemia was independent of trisomy 21 and originated in a wide spectrum of stem and progenitor cells through additional mutations in cohesin genes such as STAG2. CD117+ cells mediated the propagation and progression of the preleukemic and leukemic disease. Treatment with small molecule CD117/KIT inhibitors efficiently targeted preleukemic stem cells and blocked progression to leukemia; thereby laying the groundwork for early prevention strategies in Down syndrome newborns.

Down syndrome and leukemia: from basic mechanisms to clinical advances.

Project description:Children with Down syndrome (DS, trisomy 21) are at a significantly higher risk of developing acute leukemia compared to the overall population. Many studies investigating the link between trisomy 21 and leukemia initiation and progression have been conducted over the last two decades. Despite improved treatment regimens and significant progress in iden - tifying genes on chromosome 21 and the mechanisms by which they drive leukemogenesis, there is still much that is unknown. A focused group of scientists and clinicians with expertise in leukemia and DS met in October 2022 at the Jérôme Lejeune Foundation in Paris, France for the 1st International Symposium on Down Syndrome and Leukemia. This meeting was held to discuss the most recent advances in treatment regimens and the biology underlying the initiation, progression, and relapse of acute lymphoblastic leukemia and acute myeloid leukemia in children with DS. This review provides a summary of what is known in the field, challenges in the management of DS patients with leukemia, and key questions in the field.

Inverse Comorbidity between Down Syndrome and Solid Tumors: Insights from In Silico Analyses of Down Syndrome Critical Region Genes.

Project description:An inverse comorbidity has been observed between Down syndrome (DS) and solid tumors such as breast and lung cancers, and it is posited that the overexpression of genes within the Down Syndrome Critical Region (DSCR) of human chromosome 21 may account for this phenomenon. By analyzing publicly available DS mouse model transcriptomics data, we aimed to identify DSCR genes that may protect against human breast and lung cancers. Gene expression analyses with GEPIA2 and UALCAN showed that DSCR genes ETS2 and RCAN1 are significantly downregulated in breast and lung cancers, and their expression levels are higher in triple-negative compared to luminal and HER2-positive breast cancers. KM Plotter showed that low levels of ETS2 and RCAN1 are associated with poor survival outcomes in breast and lung cancers. Correlation analyses using OncoDB revealed that both genes are positively correlated in breast and lung cancers, suggesting that they are co-expressed and perhaps have complementary functions. Functional enrichment analyses using LinkedOmics also demonstrated that ETS2 and RCAN1 expression correlates with T-cell receptor signaling, regulation of immunological synapses, TGF-β signaling, EGFR signaling, IFN-γ signaling, TNF signaling, angiogenesis, and the p53 pathway. Altogether, ETS2 and RCAN1 may be essential for the development of breast and lung cancers. Experimental validation of their biological functions may further unravel their roles in DS and breast and lung cancers.
