Aberrant microRNA expression pattern in myelodysplastic bone marrow cells

Leukemia Research

Abstract

The microRNA/miR system might contribute to deregulation of cell homeostasis/disease phenotype. This is the first approach to generate an expression profile of 365 microRNAs in myelodysplastic syndromes (MDS) with normal karyotype (n=12) and distinct cytogenetic aberrations (n=12). In MDS-del(5q), a series of microRNAs not in the 5q-region was increased. MicroRNAs encoded on chromosomes 5, 7 and 8 were not differentially expressed in MDS with del(5q), -7 or +8. Evaluation in a larger cohort could confirm the up-regulation of the miR-1 in MDS. These findings provide evidence that MDS-haematopoiesis is distinct in its microRNA-expression pattern from non-neoplastic cells.

AML: Role of LSD1 by CRISPR (Keystone)

Find the latest rersearrch on the ability of CRISPR-Cas9 mutagenesis to profile the interactions between lysine-specific histone demethylase 1 (LSD1) and chemical inhibitors in the context of acute myeloid leukemia (AML) here.

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.
