Description
Human ILCs are classically categorized into five subsets; cytotoxic CD127-CD94+ NK cells and non-cytotoxic CD127+CD94-, ILC1s, ILC2s, ILC3s and LTi cells. Here, we identify a novel subset within the CD127+ ILC population, characterized by the expression of the cytotoxic marker CD94. These CD94+ ILCs strongly resemble conventional ILC3s in terms of phenotype, transcriptome and cytokine production, but are highly cytotoxic. IL-15 was unable to induce differentiation of CD94+ ILCs towards mature NK cells. Instead, CD94+ ILCs retained RORγt, CD127 and CD200R expression and produced IL-22 in response to IL-15. Culturing non-cytotoxic CD127+ ILC1s or ILC3s with IL-12 induced upregulation of CD94 and cytotoxic activity, effects that were not observed with IL-15 stimulation. Thus, human helper ILCs can acquire a cytotoxic program without differentiating into NK cells.

RNA-seq analysis documented mRNA changes in total pancreatic RNA preparations 14 days after Ptf1a inactivation. Overall design: pancreas mRNA profiles of Tamoxifen treated adult control mice [Ptf1a(CreER/+)] and Ptf1a conditional knockout mice [Ptf1a(CreER/fl)] were generated by deep sequencing using an Illumina Hiseq 2500.

- Drosophila Gene 1.1 ST Array (drogene11st)
Description
The Drosophila TRIM-NHL protein Brain tumor (Brat) plays important roles during early embryogenesis, in cell fate decisions, during neurogenesis and in mature neurons. Brat is an RNA-binding protein and functions as translational repressor. However, which RNAs Brat regulates and how RNA-binding specificity is achieved, is unknown. Using RNA-Immunoprecipitation we identify Brat-bound mRNAs in Drosophila embryos and define a consensus binding motif.

Description
Mammalian nephrons are the physiological subunits of mammalian kidneys which consist of different highly apicobasally polarized epithelial cell types. In epithelial cells polarization is controlled by evolutionary conserved CRB, PAR, or SRIB complexes. Here, we focused on the role of Pals1/Mpp5 in the nephron. Pals1, a core component of the apical membrane determining CRB complex, is highly expressed in renal tubular epithelial and glomerular epithelial cells (podocytes). Surprisingly, haplo-deficient mice, lacking one Pals1/Mpp5 allele in the nephron developed a strong phenotype, accompanied by cyst formation and severe renal filtration barrier defects, which subsequently lead to death after 6-8 weeks. Supporting studies in Drosophila nephrocytes, and epithelial cell culture models elucidated the role of Pals1 as a dose dependent upstream regulator of the crosstalk between Hippo- and TGF-signaling during nephrogenesis.

Description
Transcriptional dysregulation is an early feature of Huntington''s disease (HD). We observed gene-specific changes in H3K4me3 at transcriptionally repressed promoters in R6/2 mouse and human HD brain. Genome-wide analysis showed a novel chromatin signature for this mark. Reducing the levels of the H3K4 demethylase SMCX/Jarid1c in primary neurons reversed down-regulation of key neuronal genes caused by mutant Huntingtin (Htt) expression. Finally, reduction of SMCX/Jarid1c in primary neurons from BACHD mice or the single Jarid1 in a Drosophila HD model was protective. Therefore, targeting this epigenetic signature may be an effective strategy to ameliorate the consequences of HD. Overall design: mRNA-seq in wild type and R6/2 cortex and striatum at 8 and 12 weeks.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Many flowering plants attract pollinators by offering a reward of floral nectar. Remarkably, the molecular events involved in the development of nectaries, the organs that produce nectar, as well as the synthesis and secretion of nectar itself, are poorly understood. Indeed, to date, no genes have been shown to directly affect the de novo production or quality of floral nectar. To address this gap in knowledge, the ATH1 Affymetrix GeneChip array was used to systematically investigate the Arabidopsis nectary transcriptome to identify genes and pathways potentially involved in nectar production. In this study, we identified a large number of genes differentially expressed between secretory lateral nectaries and non-secretory median nectary tissues, as well as between mature lateral nectaries (post-anthessis) and immature lateral nectary tissue (pre-anthesis).

Description
A control vs. genetic knockout experiment aimed at determining what RNAs are upregulated or downregulated in e11.5 mouse proximal limb tissue lacking the Lmx1b gene. Because Lmx1b is required for dorsal-ventral patterning of the limb, this screen gives insight into what putative downstream targets of Lmx1b contribute to dorsal-ventral patterning.
Publication Title
Identification of genes controlled by LMX1B in the developing mouse limb bud.
