Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Microarray analysis of wild type plants and plants with reduced (ago1-27 and se-1) or increased miR156 levels (se-1 p35S:MIR156). Shoot apices were dissected from 20-day-old, short-day grown plants.
Publication Title
miR156-regulated SPL transcription factors define an endogenous flowering pathway in Arabidopsis thaliana.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Behavioral analysis confirmed that the 14-day social defeat sessions resulted in induction of depressive-like states measured in social interaction and light/dark tests. The combined data show that stress-induced depressive states are associated with molecular and structural changes that demyelinate the prefrontal cortex.
Publication Title
Chronic social defeat reduces myelination in the mouse medial prefrontal cortex.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
PU.1 is a key transcription factor for macrophage differentiation. Novel PU.1 target genes were identified by mRNA profiling of PU.1-deficient progenitor cells (PUER) before and after PU.1 activation. We used two different types of Affymetrix DNA-microarrays (430 2.0 arrays and ST 1.0 exon arrays) to characterize the global PU.1-regulated transcriptional program underlying the early processes of macrophage differentiation.

Transcriptomic profiling identifies a PU.1 regulatory network in macrophages.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
We were interested in determining what genes might be controlled by TFAP2C and/or TFAP2A, either directly or indirectly through regulation of ER-alpha and potentially other signaling pathways. We performed an microarray analysis in MCF7 cells with elimination of either TFAP2C or TFAP2A. The patterns of gene expression with alteration of TFAP2 activity were compared to changes in expression induced by estrogen exposure. Knock-down of TFAP2C in the presence of estrogen altered the pattern of several known ERalpha-regulated genes and a number of genes outside the estrogen-regulated pathways.

TFAP2C controls hormone response in breast cancer cells through multiple pathways of estrogen signaling.

Description
The aim of this experiment is to test the ability of the ortholog of Arabidopsis LFY gene from Leanworthia crassa (Lcr) to complement an Arabidopsis LFY mutant. Plants used are homozygous lfy6 mutants (EMS alleles) in Ler background which are transformed or not (for the lfy6 mutant) by genomic clones for Arabidopsis LFY (AthLFY) or Leanworthia crassa LFY (LcrLFY). Flowering was synchronized by growing plants in SD then shifting them to LD. 2 time points samples (wild type Ler) were taken at the end of the SD period as a reference for genes induced by shifting to LD, irrespective of the status at the LFY locus.
Publication Title
Evolutionary divergence of LFY function in the mustards Arabidopsis thaliana and Leavenworthia crassa.

Description
An animals ability to cope with or succumb to deleterious effects of chronic psychological stress may be rooted in the brains immune responses manifested in microglial activity. Mice subjected to chronic social defeat (CSD) were categorized as susceptible (CSD-S) or resilient (CSD-R) based on behavioral phenotyping, and their microglial RNAs were isolated and analyzed by global gene expression microarrays. Microglia transcriptome from CSD-S mice was enriched for pathways that describe phases of CNS healing to sterile injury including, inflammation, oxidative stress, debris clearance, and wound resolution. Histochemical experiments confirmed the array predictions: CSD-S microglia showed elevated phagocytosis and oxidative stress, and the brains of CSD-S but not CSD-R or HC mice showed vascular leakage of intravenously injected fluorescent tracers. The results suggest that the inflammatory profile of CSD-S microglia may be precipitated by leakage of blood-born substances into brain parenchyma. We hypothesize that these CNS-centric responses contribute to the stress-susceptible behavioral phenotype.

Decoding microglia responses to psychosocial stress reveals blood-brain barrier breakdown that may drive stress susceptibility.
