Description
Some neuropsychiatric disease, including schizophrenia, may originate during prenatal development, following periods of gestational hypoxia and placental oxidative stress. Here we investigated if gestational hypoxia promotes damaging secretions from the placenta that affect fetal development and whether a mitochondria-targeted antioxidant MitoQ might prevent this. Gestational hypoxia caused low birth-weight and changes in young adult offspring brain, mimicking those in human neuropsychiatric disease. Exposure of cultured neurons to fetal plasma or to secretions from the placenta or from model trophoblast barriers that had been exposed to altered oxygenation caused similar morphological changes. The secretions and plasma contained altered microRNAs whose targets were linked with changes in gene expression in the fetal brain and with human schizophrenia loci. Molecular and morphological changes in vivo and in vitro were prevented by a single dose of MitoQ bound to nanoparticles, which were shown to localise and prevent oxidative stress in the placenta but not in the fetus. We suggest the possibility of developing preventative treatments that target the placenta and not the fetus to reduce risk of psychiatric disease in later life. Overall design: 16 samples (4 biological replicates per group) were analysed using RNA sequencing. The 4 groups were: Normoxia+Saline (control sample), Normoxia+MitoQ-NP, Hypoxia+Saline and Hypoxia+MitoQ-NPs. Pair-wise comparison between all groups was performed.

Description
Whsc1 gene codes for a SET domain-containing H3K36 dimethylase, whose activity has been suggested, in ex vivo cell culture experiments, to control many aspects of DNA and RNA processing (replication, repair, transcription, etc). Its precise function in vivo is still unclear. Here, we use RNA-seq transcriptome analysis to study the changes in gene expression in the absence of Whsc1. Our results show that, in the experimental system used, loss of Whsc1 caused massive changes in genes affecting many fundamental cellular processes, from cell cycle to ribosome synthesis, DNA repair, replication, etc. Overall design: Whsc1-KO mice are embryonic lethal. We therefore took hematopoietic cells from fetal liver of WT and Whsc1-KO embryo littermates and injected them in to lethally irradiated RAG1-KO recipients and allowed the generation of a full Whsc1-KO hematopoietic system. Then, WT and Whsc1-KO B cells were obtained from the spleen and stimulated with LPS to induce proliferation and class switch recombination. Flow cytometry and cell cycle analyses (among others) showed the existence of serious proliferative alterations in Whsc1-KO cells. Then, we performed paired-end RNAseq analyses of 7 independent WT and 6 independent Whsc1-KO biological replicates and we used these data to identify differentially expressed genes and pathways regulated by Whsc1 in B cells.

Description
Gene expression profile of in vitro differentiated control and CD33 KO CD34+ cells (with 70-85% CD33 KO) were analyzed by RNA-seq to exclude any major impact of CD33 loss on downstream gene expression Overall design: Primary CD34+ cells were treated with CRISPR/Cas9 to disrupt the CD33 gene and grown in culture for 5-7 days prior to analysis; mRNA profile was compared to control cells from the same donor that were also treated with Cas9 and a control gRNA; 5 different donors were evaluated (CD33 KO/control for each = total 10 samples)
