Description
ING1b and GADD45a are nuclear proteins involved in the regulation of cell growth, apoptosis and DNA repair. We found that ING1b and GADD45a physically and functionally interact in the epigenetic regulation of specific target genes. In order to characterise the functional ING1b-GADD45a interaction, we performed a gain-of-function experiment in HEK293T cells by individual and combinatorial plasmid transfections and then analysed the transcriptional response via expression microarray profiling.

Description
ING1b and GADD45a are nuclear proteins involved in the regulation of cell growth, apoptosis and DNA repair. We found that ING1b and GADD45a physically and functionally interact in the epigenetic regulation of specific target genes. In order to study this interaction further, we analysed the transcriptional changes in MEF cells from single and double Ing1/Gadd45 knockout mice via microarray profiling.

Illumina HiSeq 2000
Description
We generated Gadd45a,b,g triple-knockout mouse embryonic stem cells and performed RNA-seq expression profiling under six different conditions of cell culture and in vitro differentiation. Overall design: Gadd45a,b,g triple knockout (TKO) mouse embryonic stem cells (mESC) were generated by CRISPR/Cas9. RNA-Seq was performed to compare the transcriptome in three independent Gadd45 TKO versus three independent control mESC lines under different conditions: (i) Serum cultured mESC, (ii) Vitamin C treated mESC, (iii) 2i treated mESC, (iv) mESC differentiated as embryoid bodies (EB), (v) mESC differentiated as a serum-free monolayer, and (vi) EB stimulated with retinoic acid (RA).

Description
ING1b and GADD45a are nuclear proteins involved in the regulation of cell growth, apoptosis and DNA repair. We previously found that ING1b is required to target GADD45a-mediated active DNA-demethylation via TET1 to specific loci. In order to study the impact of ING1-GADD45a on gene expression, we compared the expression profile of wildtype mouse embryonic fibroblasts (MEFs) with Ing1- and Gadd45a- single- or double-knockout (DKO) MEFs. Overall design: Gene expression profiling in all 4 genotypes of undifferentiated MEFs in triplicates.

Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Parathyroid hormone (PTH) plays an essential role in regulating calcium and bone homeostasis in the adult, but whether PTH is required at all for regulating fetal-placental mineral homeostasis is uncertain. To address this we treated Pth-null mice in utero with 1 nmol PTH (1-84) or saline and examined placental calcium transfer 90 minutes later. It was found that placental calcium transfer increased in Pth-null fetuses treated with PTH as compared to Pth-null fetuses treated with saline. Subsequently, to determine the effect of PTH treatment on placental gene expression, in a separate experiment, 90 minutes after the fetal injections the placentas were removed for subsequent RNA extraction and microarray analysis.

Description
We report high-throughput profiling of gene expression from whole zebrafish ventricles. We profile mRNA in uninjured ventricles and those undergoing regeneration 14 days after genetic ablation. This study provides a framework for understanding transcriptional changes during adult models of regeneration. Overall design: Examination of gene expression in cardiomyocytes under different states of proliferation.

Description
Mammalian insulin and IGF induce similar but not identical changes in gene expression downstream of their respective receptors. Signaling bias at the receptor differentiates the two similar ligands, though the precise mechanism is not entirely understood. We used Drosophila insulin-like peptides DILP2 and DILP5 to determine how similar insulin-like ligands regulate similar and distinct patterns of gene expression in S2 cells by RNA-Seq. Overall, DILP2 and DILP5 stimulate many of the same changes in gene expression. However, some genes are uniquely regulated by DILP2 or by DILP5. Shared and distinct gene targets were validated by q-RT-PCR with indepedent replicates. Some unique gene targets of DILP2 are involved in sugar metabolism, which is functionally related in vivo to DILP2 and not DILP5. We find that gene expression is largely regulated in parallel by DILP2 and DILP5 but some key unique targets may lead to differential physiological functions for the two insulin-like genes. Overall design: mRNA profiles from S2 cells treated with DILP2, DILP5 or solvent were sequenced on an Illumina HiSeq2500
