Description
piRNAs direct Piwi to repress transposons to maintain genome integrity in Drosophila ovarian somatic cells. piRNA maturation and association with Piwi occur at perinuclear Yb bodies, the centers of piRNA biogenesis. Here, we show that piRNA intermediates arising from the piRNA cluster flamenco (flam) concentrate into perinuclear foci adjacent to Yb bodies, termed Flam bodies. Although flam expression is not required for Yb body formation, Yb, the core component of Yb bodies, is required for Flam body formation. Abolishment of the RNA-binding activity of Yb disrupts both Yb bodies and Flam bodies. Loss of Zucchini, an endoribonuclease necessary for piRNA maturation, enlarges Flam bodies, which now superimpose with Yb bodies. Yb directly binds flam, but not neighboring protein-coding gene, transcripts. Thus, Yb integrates piRNA processing factors and piRNA intermediates into Yb bodies and Flam bodies, respectively, through direct binding to enhance piRNA biogenesis and formation of piRNA-inducing silencing complexes. Overall design: HITS-CLIP was performed using OSC (Ovarian Somatic Cells). The antibody for Drosophila Yb, which was generated in this study, was used. Obtained CLIP tags were analyzed using illumina HiSeq200.

Description
RNAseq was performed on microglia from male and female, SPF or GF mice to elucidate the genetic differences implicated by microbiota and gender. DEGs between the various groups gave some ideas on what different pathways or functions might be affected due to the different factors. Overall design: Microglia from SPF and GF mice from embryonic and adult stages of both gender were sorted for sequencing. DEGs were obtained to observe if any signicant genes were affected. Pathway analysis was performed with the set of DEGs.

Description
The modulation of chromatin status at specific genomic loci controls lymphoid differentiation. Here, we investigated the role played in this process by KAP1, the universal cofactor of KRAB-containing Zinc Finger Proteins (KRAB-ZFPs), a tetrapod-restricted family of transcriptional repressors. T cell-specific Kap1 knockout mice displayed a significant expansion of immature thymocytes and imbalances in the ratios of mature T cells in the thymus and the spleen, with impaired responses to TCR stimulation. Transcriptome and chromatin studies revealed that KAP1 directly controls the expression of a number of genes involved in TCR and cytokine signalling, among which Traf1 and FoxO1, and is strongly associated with cis-acting regulatory elements marked by the H3K9me3 repressive mark on the genome of thymic T cells. Likely responsible for tethering KAP1 to at least part of its genomic targets, a small number of KRAB/ZFPs are selectively expressed in T lymphoid cells. These results reveal the so far unsuspected yet important role of KRAB/KAP1-mediated epigenetic regulation in T lymphocyte differentiation and activation.
