Description
In Saccharomyces cerevisiae, the maturation of both pre-rRNA and pre-small nucleolar RNAs (pre-snoRNAs) involves common factors, thereby providing a potential mechanism for the coregulation of snoRNA and rRNA synthesis. In this study, we examined the global impact of the double-stranded-RNA-specific RNase Rnt1p, which is required for pre-rRNA processing, on the maturation of all known snoRNAs. In silico searches for Rnt1p cleavage signals, and genome-wide analysis of the Rnt1p-dependent expression profile, identified seven new Rnt1p substrates. Interestingly, two of the newly identified Rnt1p-dependent snoRNAs, snR39 and snR59, are located in the introns of the ribosomal protein genes RPL7A and RPL7B. In vitro and in vivo experiments indicated that snR39 is normally processed from the lariat of RPL7A, suggesting that the expressions of RPL7A and snR39 are linked. In contrast, snR59 is produced by a direct cleavage of the RPL7B pre-mRNA, indicating that a single pre-mRNA transcript cannot be spliced to produce a mature RPL7B mRNA and processed by Rnt1p to produce a mature snR59 simultaneously. The results presented here reveal a new role of yeast RNase III in the processing of intron-encoded snoRNAs that permits independent regulation of the host mRNA and its associated snoRNA.

Description
Identification of genes involved in ocular birth defects remains a challenge. To facilitate the identification of genes associated with cataract, we developed iSyTE (integrated Systems Tool for Eye gene discovery; http://bioinformatics.udel.edu/Research/iSyTE). iSyTE contains microarray gene expression profiles of the mouse embryonic lens as it transitions from the stage of placode invagination to that of vesicle formation. We identified differentially regulated genes by comparing lens microarray profiles to those representing whole embryonic body (WB) without ocular tissue. These were then utilized to generate a ranked list of lens-genes enrichment, which can be viewed as iSyTE tracks in the UCSC Genome browser to aid identification of genes with lens function.

Description
The paired-end next-generation sequencing of all small RNAs of less than 200 nucleotides in length from four different human cell lines (SKOV3ip1, MCF-7, BJ-Tielf, INOF) allowed us to determine the exact sequence(s) and variations of human box C/D snoRNAs (small nucleolar RNAs), revealing processing patterns of this class of molecules. Two distinct groups of box C/D snoRNAs were identified based on the position of their ends with respect to their characteristic boxes and the terminal base pairing potential. Short box C/D snoRNAs start sharply 4 or 5 nucleotides upstream of their box C and end 2 or 3 nucleotides downstream of their box D. In contrast, long box C/D snoRNAs start 5 or 6 nucleotides upstream of their box C and end 4 or 5 nucleotides downstream of their box D, increasing the likelihood of formation of a k-turn between their boxes C and D. Sequencing of SKOV3ip1 cells following the depletions of NOP58, a core box C/D snoRNA-binding protein and of RBFOX2, a splicing factor, shows that the short box C/D snoRNA forms are significantly more affected by the depletion of RBFOX2 while the long snoRNA forms, which display more canonical box C/D snoRNA features, are significantly more affected by the depletion of NOP58. Together the data suggest that box C/D snoRNAs are divided into at least two groups of RNA with distinct maturation and functional preferences. Overall design: Small RNAs (<200 nucleotides) were isolated from different human cell lines that were either untreated or depleted of NOP58 or RBFOX2 using specific siRNAs. The resulting libraries were multiplexed and paired-end sequenced using Illumina HiSeq.

Description
Purpose: The goals of this study are to compare transcriptome profiling (RNA-seq) resulting from the knockout of Hira in undifferentiated mouse embryonic stem cells (mESCs) and in day 15 differentiated cardiomyocytes.Methods: RNA extraction was done in duplicate from WT and Hira-null mESCs at day0 and day15 using TRIzol reagent. RNAseq was done onIllumina Nextseq500 and processed by the ICH genomics facility, reads were aligned and normalised using BOWTIE and DEseq R2 package. Gene lists were filtered using adjusted p-value = 0.05 and absolute fold change = 2. Results:We identified 1680 transcripts changed in the absence of HIRA in day 15 differentiated cardiomyocytes. GO term cardiovascular system development was the most downregulated gene set(p-value = 0.01 and FDR =0.1. Conclusion: this study analysis the role of HIRA in early cardiac mesoderm development usinf an invitro mESCs model. Overall design: mRNA profile of WT(control) and Hira-null (KO) undifferentiated mESCs and mESCs- derived cardiomyocytes at day15 were generated by deep sequencing in duplicates using Illumina Nextseq 500 platform.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
The heart responds to pathological overload through myocyte hypertrophy. In our study, we found that this response is regulated by cardiac fibroblasts via a novel paracrine mechanism involving plasma membrane calcium ATPase 4 (PMCA4). PMCA4 deletion in mice, both systemically and specifically in fibroblasts, reduces the hypertrophic response to pressure overload; however, knocking out PMCA4 specifically in cardiomyocytes does not produce this effect. Mechanistically, our microarray data on fibroblasts isolated from PMCA4 WT and PMCA4 knockout animals showed that cardiac fibroblasts lacking PMCA4 produce higher levels of secreted frizzled related protein 2 (sFRP2), which inhibits the hypertrophic response in neighbouring cardiomyocytes.
