Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
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. MicroRNAs (miRNAs) are small non-coding RNAs which play a pivotal role in several cellular functions. In this study, we investigated miRNA and gene expression profiles in a series of adult ALL cases by microarray analysis and combined them by bioinformatic analysis. Interestingly, those miRNAs which are differentially expressed between the ALL classes accounted for a large proportion of miRNA/mRNA expression pairs identified by the above analysis. Moreover, the analysis highlighted several putative miRNA targets involved in apoptosis and cell-cycle regulation.

Description
T-lymphocyte activation is efficiently mimicked in vitro by treatment with anti CD3 / anti CD28 antibodies. We report miR-21 induction upon CD3/CD28 stimulation of primary T-lymphocytes. In order to assess the function of miR-21 in T-lymphocytes we interfered with miR-21 function by lentiviral transduction of a miR-21 sponge construct. MRNA profile of miR-21 sponge and control transduced T-lymphocytes 48hrs after stimulation.

Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
In order to investigate a potential involvement of miRNAs in BCR stimulation, in the present work we first evaluated their expression following IgM cross-linking in CLL cells, as well as in healthy B lymphocytes. Next, to infer putative miRNA targeting networks, we combined miRNA profiling results with gene expression and functional analyses

Description
The integration of positive and negative intra- and extra-cellular signals dictates whether a cell will proliferate or differentiate. While it is intuitive to speculate that nutrients availability may influence this alternative, a comprehensive complement of the molecular determinants involved in this process has not been elucidated yet. In this study, we will investigate how nutrients (glucose) affect skeletal myogenesis. C2C12 cells will be cultured in high glucose and low glucose conditions, and their differenciation will be studied.
Publication Title
Glucose restriction inhibits skeletal myoblast differentiation by activating SIRT1 through AMPK-mediated regulation of Nampt.
