(Submitter supplied) Acute lymphoblastic leukemia (ALL) is an heterogeneous disease comprising several subentities that differ for both immunophenotypic and molecular characteristics. Over the years, the biologic understanding of this neoplasm has largely increased. Gene expression profiling has recently allowed to identify specific signatures for the different ALL subsets and permitted identification of pathways deregulated by a given lesion. more...

(Submitter supplied) MicroRNAs (miRNAs) are noncoding RNAs of approximately 22 nucleotides in length that usually suppress the translation of target messenger RNAs (mRNAs) through partial complementarity to the 3¡¦ untranslated region (3¡¦ UTR) of protein-coding mRNAs in animals. However, there is increasing evidence that miRNAs can also reduce the steady-state levels of their target mRNAs in animals. In this investigation, both miRNA and mRNA profiles from the undifferentiated human embryonic stem cell line hES-T3 (T3ES), hES-T3 derived embryoid bodies (T3EB) and hES-T3 differentiated fibroblast-like cells (T3DF) were quantitatively determined. more...

(Submitter supplied) In order to investigate the patterns of genetic lesions in a panel of 23 Human Multiple Myeloma Cell Lines (HMCLs), we made a genomic integrative analysis involving FISH and both gene expression and genome-wide profiling approaches. The expression profiles of the genes targeted by the main IGH translocations showed that the WHSC1/MMSET gene involved in t(4;14)(p16;q32) was expressed at different levels in all of the HMCLs, and that the expression of the MAF gene was not restricted to the HMCLs carrying t(14;16)(q32;q23). more...

(Submitter supplied) We investigated the miRNA expression in ex vivo human erythroid cultures from K562 cells. Hypothetically, the decline of certain miRNAs may promote erythropoiesis by unblocking expression of key functional proteins while the up-regulation of other miRNAs may block commitment to non-erythroid lineages. By comparison with the miRNA expression changes in human umbilical cord blood-derived CD34 cells, signature miRNAs for erythroid development can be discovered. more...

(Submitter supplied) We investigated the miRNA expression in ex vivo human erythroid cultures from umbilical cord blood (UCB)-derived CD34 cells. Hypothetically, the decline of certain miRNAs may promote erythropoiesis by unblocking expression of key functional proteins while the up-regulation of other miRNAs may block commitment to non-erythroid lineages. Therefore, discovering the patterns and sequence of miRNA expression during hematopoietic differentiation will provide insights about the functional roles of these tiny noncoding genes. more...

MicroRNAs (miRNAs) are small, non-coding RNA molecules which are emerging as key regulators of numerous cellular processes. Compelling evidence links miRNAs to the control of neuronal development and differentiation, however, little is known about their role in neurodegeneration. more...

(Submitter supplied) Non-small-cell lung cancer (NSCLC), which is comprised mainly of adenocarcinoma and squamous cell carcinoma (SCC), is the cause of 80% of all lung cancer deaths in the US. NSCLC is also associated with a high rate of relapse following clinical treatment and therefore requires robust prognostic markers to better manage therapy options. The aim of this study was to identify miRNA expression profiles in squamous cell carcinoma (SSC) of the lung that would better predict prognosis.

(Submitter supplied) Recently, the p53-miR-34a network was identified to play an important role in tumorigenesis. As in acute myeloid leukemia with complex karyotype (CK-AML) TP53 alterations are the most common known molecular lesion, we further analyzed the p53-miR-34a axis in CK-AML with known TP53 status. Clinically, low miR-34a expression and TP53 alterations predicted for chemotherapy resistance and inferior outcome. more...

(Submitter supplied) BRCA1 deregulation is a frequent event in the pathogenesis of breast as well as other cancers. In addition to the DNA repair functions of BRCA1, it is involved in a wide range of cellular processes such as cell cycle, chromatin remodeling or transcription. However, the molecular events underlying BRCA1-associated tumorigenesis are still largely unknown. In order to deepen our understanding of BRCA1-associated tumorigenesis, we integrated data from mRNA and miRNA microarray experiments on the HCC1937 breast cancer cell line, and the isogenic HCC1937 stably expressing BRCA1, to obtain significant miRNA-mRNA relationships associated to the presence of the BRCA1 gene. more...

(Submitter supplied) Lymphoblastic lymphoma (LBL) is one of the most frequent occurring pediatric non-Hodgkin lymphomas. In the WHO classification scheme pediatric LBL is considered to be the same disease entity as pediatric acute lymphoblastic leukemia (ALL). However, it is unclear whether the genetic basis of pediatric LBL development is similar to that of pediatric ALL. We performed genome-wide analyses of copy number aberrations in 12 T-LBL and 7 precursor B-cell LBL pediatric cases using high-resolution SNP-based array CGH. more...
