Description
FOXE3 is a lens specific transcription factor that has been associated with anterior segment ocular dysgenesis. To determine the transcriptional target(s) of FOXE3 that are indispensable for the anterior segment development, we examined the transcriptome and the proteome of cells expressing truncated FOXE3 responsible for Peters anomaly identified through linkage-coupled next-generation whole exome sequencing. We found that DNAJB1, an autophagy-associated protein, was the only candidate exhibiting differential expression in both screens. We confirmed the candidacy of DNAJB1 through chromatin immunoprecipitation and luciferase assays while knockdown of DNAJB1 in human lens epithelial cells resulted in mitotic arrest. Subsequently, we targeted dnajb1a in zebrafish through injection of a splice-blocking morpholino. The dnajb1a morphants exhibited underdeveloped cataractous lenses with persistent apoptotic nuclei. In conclusion, we have identified DNAJB1 as a transcriptional target of FOXE3 in a novel pathway that is crucial for development of the anterior segment of the eye. Overall design: Human Embryonic Kidney (HEK293FT) cells were transfected with the expression vector (pT-RexTM-DEST30) harboring either the wild type or the mutant (C240*) FOXE3 ORF (open reading frame). The experimental design included a total of eight biological replicates of cells expressing the wild type and eight replicates of mutant FOXE3 along with eight non-transfected controls. Cells were harvested 24-hour post-transfection and subjected to total RNA isolation for the preparation of whole transcriptome next-generation sequencing libraries. Initially, we examined the quality of transcriptome libraries on a MiSeq genome analyzer. Subsequent to confirmation of the quality, all libraries were paired-end sequenced (2 x 100 bp) using Illumina TruSeq Cluster V3 flow cell at a concentration of 13.0 pM in two separate lanes (12 bar-coded mRNA pooled libraries in each lane) on a HiSeq 2000 genome analyzer.

Description
We analyzed gene expression in CD4+ cells sorted from naïve or D30 Mycobacterium tuberculosis-infected mice and incubated in vitro in the presence or absence of Schistosoma egg antigen. We found genes associated with Th1 function, T cell signaling, T cell costimulation and T cell activation were downregulated in SEA-treated cells, while expression of Th2 cytokines was below the threshold for detection. Overall design: RNAseq results for 3 replicates for naïve or CD4+ T cells from M.tuberculosis-infected mice treated with or without Schistosoma egg antigen in vitro.

Description
We have determined the gene expression profile induced by 17 alpha-ethynyl estradiol (EE) in Ishikawa cells, a human uterine-derived estrogen-sensitive cell line, at various doses (1 pM, 100 pM, 10 nM, and 1 microM) and time points (8, 24, and 48 h). The transcript profiles were compared between treatment groups and controls (vehicle-treated) using high-density oligonucleotide arrays to determine the expression level of approximately 38,500 human genes. By trend analysis, we determined that the expression of 2560 genes was modified by exposure to EE in a dose- and time-dependent manner (p </= 0.0001). The annotation available for the genes affected indicates that EE exposure results in changes in multiple molecular pathways affecting various biological processes, particularly associated with development, morphogenesis, organogenesis, cell proliferation, cell organization, and biogenesis. All of these processes are also affected by estrogen exposure in the uterus of the rat. Comparison of the response to EE in both the rat uterus and the Ishikawa cells showed that 71 genes are regulated in a similar manner in vivo as well as in vitro. Further, some of the genes that show a robust response to estrogen exposure in Ishikawa cells are well known to be estrogen responsive, in various in vivo studies, such as PGR, MMP7, IGFBP3, IGFBP5, SOX4, MYC, EGR1, FOS, CKB, and CCND2, among others. These results indicate that transcript profiling can serve as a viable tool to select reliable in vitro systems to evaluate potential estrogenic activities of target chemicals and to identify genes that are relevant for the estrogen response.

Description
The emergence of multidrug resistant (MDR) Mycobacterium tuberculosis (Mtb) strains, resistant to the frontline anti-tubercular drugs rifampicin and isoniazid, forces treatment with less effective and toxic second-line drugs and stands to derail TB control efforts. However, the immune response to MDR Mtb infection remains poorly understood. Here, we determined the RNA transcriptional profile of in vitro generated macrophages to infection with either drug susceptible Mtb HN878 or MDR Mtb W_7642 infection. Overall design: Bone marrow-derived macrophages (BMDMs) from WT and Il1r1–/– mice were derived in 7 days in GM-CSF supplemented complete DMEM. Cells were infected with either Mtb HN878 or Mtb W_7642 (multiplicity of infection = 1) and RNA samples collected after 6 days.

Description
Bud endodormancy induction response of two genotypes (Seyval a hybrid white wine grape and V. riparia, PI588259 a native north american species) was compared under long and short photoperiod. Three separate replicates (5 plants/replicate) were treated in each of 2 separate years (2007 and 2008) to generate paradormant (LD) and same aged endodormancy-induced (SD) buds for transcriptomic, proteomic and metabolomic analysis. Potted, spur-pruned two to six-year-old vines were removed from cold storage (Seyval 3-19-07, 3/18/08; V. riparia 3/26/07, 3/24/08) and grown under a LD (15 h) at 25/20 + 3C day/night temperatures (D/N). When vines reached 12-15 nodes they were randomized into groups for differential photoperiod treatments. On 4/30/07 and 4/28/08 LD and SD (13 h) treatments were imposed with automated photoperiod system (VRE Greenhouse Systems). Temperatures were maintained at 25/20 + 3C D/N. Three replications (5 vines/replication) were harvested between 5/07-6/07 and then again in 5/08-6/08. At 1, 3, 7, 14, 21, 28 and 42 days of differential photoperiod treatment, buds were harvested from nodes 3 to 12 (from the base of the shoot) of each separate replicate, immediately frozen in liquid nitrogen, and placed at -80C for future RNA, protein and metabolite extraction. These time points encompass early reversible phases as well as key time points during transition to irreversible endodormancy development. After photoperiod treatments and bud harvests, all pruned vines were returned to LD and monitored for bud endodormancy. The endodormant vines were identified after 28 days and moved to cold storage. The nondormant vines were allowed to grow again and induced into dormancy at a later date.
