Affymetrix Murine Genome U74A Array (mgu74a)
Description
This series represent several subgroups of experiments designed to investigate the role of basal immunoglobulin signaling in immature B cell development. The first subgroup of arrays (Ctrl Mhi, Cre Mhi, Cre Mlo) was done to identify the changes in gene expression in immature B cells as a consequence of inducible deletion of surface IgM expression via Cre-LoxP mediated excision of Ig heavy chain. The second subgroup of arrays (GFPneg, GFPpos, FxE Ctrl, FxE HA) was done to identify the changes in gene expression in immature B cells as a consequence of blockade of tyrosine kinase signaling with herbimycin A treatment. The third subgroup of arrays (FxD, FxE, B6 Mneg, HEL Mhi) was done to establish gene expression profiles of immature B, pre B and pro B cells as reference platforms for the other two subgroups.

- Affymetrix Murine Genome U74A Version 2 Array (mgu74av2)
Description
Selection of B cells subjected to hypermutation in germinal centres (GC) during T-dependent (TD) antibody responses yields memory cells and long-lived plasma cells that produce high affinity antibodies biased to foreign antigens rather than self-antigens. GC also form in T-independent (TI) responses to polysaccharide antigens but failed selection results in GC involution and memory cells are not generated. To date there are no markers that allow phenotypic distinction of T-dependent and T-independent germinal centre B cells. We have now compared the global gene expression of GC B cells purified from mice immunized with either TD or TI antigens and identified eighty genes that are differentially expressed in TD GC.
Publication Title
Axon growth and guidance genes identify T-dependent germinal centre B cells.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
We isolated mutants in Arabidopsis with enhanced ambient temperature response. Microarray analysis was performed to understand the extent to which ambient temperature transcriptome is perturbed in the mutants in comparison with the WT at non inductive 12 C and after shift to inductive 27 C for 2 h and 24 h.

Description
Many animal and plant species exhibit increased growth rates, reach larger sizes and, in the cases of crops and farm animals, produce higher yields when bred as hybrids between genetically differing strains, a phenomenon known as hybrid vigour or heterosis. Despite the importance of heterosis, and its extensive genetic analysis, there has been little understanding of its molecular basis. We aimed to determine whether characteristics of the leaf transcriptome, as an indicator of the innate functional genetic architecture of a plant line, could be used as markers to predict heterosis and the performance of hybrids, a methodology we term Association Transcriptomics. Relationships between transcript abundance of specific genes and the values of heterosis and heterosis-dependent traits were identified and mathematical models were constructed that relate gene expression characteristics in inbred lines of Arabidopsis thaliana and maize with vegetative biomass and for grain yield, respectively, in corresponding hybrids.

Description
The Arabidopsis cytochrome P450 KLUH (KLU)/CYP78A5 promotes organ growth in a non-cell autonomous manner. To identify genes regulated by KLU activity, homozygous klu-2 mutants carrying constructs for EtOH-inducible overexpression of wild-type KLU (35S::AlcR-AlcA::KLU) or of enzymatically inactive KLU protein (35S::AlcR-AlcA::KLUmut) were induced with EtOH and sampled at 90 min and 240 min after induction for gene expression changes.

Description
We performed micrarrays to investigate neuronal gene expression changes during acute inflammatory CNS axon injury using the murine myelin oligodendrocyte glycoprotein 35-55 (MOG35-55)-induced experimental autoimmune encephalomyelitis (EAE) model. The present study was assigned to assess the direct and indirect endogenous neuronal response to spinal axonal injury in the motor and sensory cortex.
