Affymetrix Zebrafish Genome Array (zebrafish)
Description
Gene expression was measured using microarrays in 8 hour postfertilization embryos, comparing control versus ethanol-treated (2 to 8 hours postfertilization) embryos. This experiment was performed to determine the gene expression changes that occur in response to ethanol treatment as a model of fetal alcohol spectrum disorder.
Publication Title
Ethanol exposure disrupts extraembryonic microtubule cytoskeleton and embryonic blastomere cell adhesion, producing epiboly and gastrulation defects.

Illumina HiSeq 4000
Description
A LHX4 transgenic reporter line with high specificity for developing mouse cone photoreceptors was identified and used to purify early stage cone photoreceptors for profiling by single cell RNA sequencing. Overall design: Collection of FACS-sorted LHX4::GFP+ E14.5 early cones and LHX4::GFP- retinal cells for further analysis.

Description
Here we report a transcriptomic analysis of fate-restricted progenitor cells biased to produce cone photoreceptors and horizontal cells, marked by the THRB cis-regulatory element ThrbCRM1. Comparison to a control population enriched in multipotent progenitor cells identified several genes considered to be pan-progenitor, such as VSX2, LHX2, and PAX6, as downregulated in these fate-restricted retinal progenitor cells Overall design: Comparison of two FACS-sorted chick retinal progenitor cell populations after electroporation of reporter plasmids and 20hr culture.
Publication Title
Fate-restricted retinal progenitor cells adopt a molecular profile and spatial position distinct from multipotent progenitor cells.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Temporal coordination of developmental programs is necessary for normal ontogeny, but the mechanism by which this is accomplished is poorly understood. We have previously shown that two components of the Mediator CDK8 module, CENTER CITY (CCT/MED12) and GRAND CENTRAL (GCT/MED13), are required for timing of pattern formation during embryogenesis in Arabidopsis.
Publication Title
The Arabidopsis Mediator CDK8 module genes CCT (MED12) and GCT (MED13) are global regulators of developmental phase transitions.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Chronic obstructive pulmonary disease (COPD) is an inflammatory lung disease with complex pathological features and largely unknown etiologies. Identification and validation of biomarkers for this disease could facilitate earlier diagnosis, appreciation of disease subtypes and/or determination of response to therapeutic intervention. To identify gene expression markers for COPD, we performed genome-wide expression profiling of lung tissue from 56 subjects using the Affymetrix U133 Plus 2.0 array. Lung function measurements from these subjects ranged from normal, un-obstructed to severely obstructed. Analysis of differential expression between cases (FEV1<70%, FEV1/FVC<0.7) and controls (FEV1>80%, FEV1/FVC>0.7) identified a set of 65 probe sets representing discrete markers associated with COPD. Correlation of gene expression with quantitative measures of airflow obstruction (FEV1 or FEV1/FVC) identified a set of 220 probe sets. A total of 31 probe sets were identified that showed evidence of significant correlation with quantitative traits and differential expression between cases and controls.

- Affymetrix Drosophila Genome 2.0 Array (drosophila2)
Description
Using high throughput sequencing of Drosophila head RNA, a small set of miRNAs that undergo robust circadian oscillations in levels were discovered. We concentrated on a cluster of six miRNAs, mir-959-964, all of which peak at about ZT12 or lights-off. The data indicate that the cluster pri-miRNA is transcribed under bona fide circadian transcriptional control and that all 6 mature miRNAs have short half-lives, a requirement for oscillating. Manipulation of food intake dramatically affects the levels and timing of cluster miRNA transcription with no more than minor effects on the core circadian oscillator. This indicates that the central clock regulates feeding, which in turn regulates proper levels and cycling of the cluster miRNAs. Viable Gal4 knock-in as well as cluster knock-out and over-expression strains were used to localize cluster miRNA expression as well as explore their functions. The adult head fat body is a major site of expression, and feeding behavior, innate immunity, metabolism, and perhaps stress responses are under cluster miRNA regulation. The feeding behavior results indicate that there is a feedback circuit between feeding time and cluster miRNA function as well as a surprising role of post-transcriptional regulation in these behaviors and physiology.

Overall design: Six samples of small RNA libraries (RNA size 19 to 29 nucleotides long) were prepared from Drosophila heads, each collected at one circadian time point during a light-dark cycle (ZT0, ZT4, ZT8, ZT12, ZT16, ZT20).
