Description
Memory stabilization after learning requires transcriptional and translational regulations in the brain, yet the temporal molecular changes following learning have not been explored at the genomic scale. We here employed ribosome profiling and RNA sequencing to quantify the translational status and transcript levels in mouse hippocampus following contextual fear conditioning. We identified 104 genes that are dynamically regulated. Intriguingly, our analysis revealed novel repressive regulations in the hippocampus: translational suppression of ribosomal protein-coding genes at basal state; learning-induced early translational repression of specific genes; and late persistent suppression of a subset of genes via inhibition of ESR1/ERa signaling. Further behavioral analyses revealed that Nrsn1, one of the newly identified genes undergoing rapid translational repression, can act as a memory suppressor gene. This study unveils the yet unappreciated importance of gene repression mechanisms in memory formation. Overall design: The application of ribosome profiling and RNA-seq techniques to mouse hippocampi tissues after contextual fear conditioning and to mouse hippocampal primary cultures. Mouse ESCs were also examined.

Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Acute rejection in cardiac transplant patients is still a contributing factor to limited survival of the implanted heart. Currently there are no biomarkers in clinical use that can predict, at the time of transplantation, the likelihood of post-transplantation acute rejection, which would be of great importance for personalizing immunosuppressive treatment. Within the Biomarkers in Transplantation initiative, the predictive biomarker discovery focused on data and samples collected before or during transplantation such as: clinical variables, genes and proteins from the recipient, and genes from the donor. Based on this study, the best predictive biomarker panel contains genes from the recipient whole blood and from donor endomyocardial tissue and has an estimated area under the curve of 0.90. This biomarker panel provides clinically relevant prediction power and may help personalize immunosuppressive treatment and frequency of rejection monitoring.

Description
Gene expression was studied from the blood derived RNAs of the Finnish family members as well as from 10 controls using GeneChip Human Genome U133 Plus2 (Affymetrix). Eight out of 10 family members in the expression analysis are heterozygous for the NPAT c.2437-2438delAG, three of which are NLPHL cases.

Description
Gene expression profiles of 10 uterine leiomyomas and their matched normal myometrium specimens were studied using Affymetrix GeneChip Human Genome U133 Plus 2.0 gene expression arrays. Four tumors displayed a codon 44 mutation, four carried a intron 1 mutation, and the remaining two displayed no MED12 mutation.

Description
Autism spectrum disorders (ASDs) are a group of developmental disorders that cause variable and heterogeneous phenotypes across three behavioral domains such as atypical social behavior, disrupted communications, and highly restricted and repetitive behaviors. In addition to these core symptoms, other neurological abnormalities are associated with ASD, including intellectual disability (ID). However, the molecular etiology underlying these behavioral heterogeneities in ASD is unclear. Mutations in SHANK2 genes are associated with ASD and ID. Interestingly, two lines of Shank2 knockout mice (e6-7 KO and e7 KO) showed shared and distinct phenotypes. Here, we found that the expression levels of Gabra2, as well as of GABA receptor-mediated inhibitory neurotransmission, are reduced in Shank2 e6-7, but not in e7 KO mice compared with their own wild type littermates. Furthermore, treatment of Shank2 e6-7 KO mice with an allosteric modulator for the GABAA receptor reverses spatial memory deficits, indicating that reduced inhibitory neurotransmission may cause memory deficits in Shank2 e6-7 KO mice. This article is part of the Special Issue entitled ''Ionotropic glutamate receptors''. Overall design: Compare gene expression profiles between wild-type and knock-out mutants mice using RNA-Seq (Illumina platform: Hi-Seq 2500)

Description
ES cell lines were established from mouse embryos, which were homozygous for the Trim33-flox allele and carried the UbcCreERT2 transgene. Cells were cultured without feeder cells in the presence of LIF and 2i. Embryoid bodies (EBs) were generated using the ATCC protocol on low attachment dishes under differentiating conditions. EBs were induced with Tamoxifen at day 1 and harvested at days 2 and 2.5, respectively. Overall design: Investigate differentially expressed genes in control and Trim33-deficient embryoid bodies derived from mouse embryonic stem cells
