QuantSeq analysis in the hippocampus of WT and PHF2 t/g mice

ABSTRACT: Long-term memory formation is attributed to experience-dependent gene expression. Dynamic changes in histone methylation status are essential for epigenetic regulation of memory consolidation-related genes. Here, we demonstrated that plant homeodomain finger protein 2 (PHF2) histone demethylase is upregulated in the mouse hippocampus during experience and plays an essential role in memory formation. QuantSeq analysis was performed to examine differential gene expression in the hippocampus of WT and PHF2 t/g mice. Transgenic mice were created by injecting the CMV-Flag-PHF2 vector into fertilized eggs from C57BL6 mice. Transgenic lines were established from 9 founders that were identified via PCR-based genotyping. Among the transgenic lines, mice with high PHF2 expressed brains were singled out for breeding. First, selected heterozygote males were bred with heterozygote females which produced homozygote, heterozygote and wild littermates. Since it is difficult to differentiate between hetero and homo mice with genotyping, we separated homo mice from hetero mice by breeding each of hetero and homo mice with wild type mice and confirming the genotypes of their offspring. In other words, hetero mice bred with wild type mice would have both wild type and hetero genotype of offspring, while homo mice bred with wild type mice would only have hetero genotype of offspring. Through this process, we particularly selected the homo mice and this transgenic line was used and maintained for this experiment.

Early life stress in fathers impairs synaptic plasticity in the offspring - brain collected after acute swim stress

Project description:We show that traumatic stress experienced by males in early postnatal life impairs memory in their offspring, blocks long-term potentiation (LTP) and favors long-term depression (LTD). These effects are accompanied by suppression of key molecular pathways involved in neuronal plasticity both at rest and after acute stress. Male mice were exposed to chronic traumatic stress in early postnatal life and were later bred to naM-CM-/ve females to produce second-generation offspring. Memory performance was evaluated in the offspring, and synaptic plasticity was examined in the hippocampus and the amygdala, brain areas important for memory formation. The two groups tested were 1: offspring of fathers which were stressed (MSUS - maternal separation unpredictable stress) and 2: offspring of non-stressed fathers (control). Genome-wide gene expression in hippocampus of these two groups was assessed at rest and after acute stress (this study).

Heterozygous and Homozygous Knock-Out of USP7 mouse models [mouse_RNA-seq]

Project description:RNAseq analysis of USP7 conditional knock-out (cKO) mice. They were designed to flox exon 6 of USP7 and to allow deletion of exon 6 upon expression of Cre recombinase 27. USP7FL/FL mice were bred with Vav1-Cre mice to obtain USP7FL/wt-Vav1-Cre mice (heterozygote). USP7FL/FL-Vav1-Cre mice (homozygote) were obtained via breeding of heterozygous cKO mice.

Gene expression profiles in the hippocampus of the Rp58 hetero-KO and the control wild-type mice in adulthood and old age.

Project description:The early onset of microglia activation in the Rp58 hetero-KO mice raised the possibility that chronic inflammation in the brain was induced by mutation even in the early life stage. To test this possibility, we examined gene expression profiles in the hippocampus of the Rp58 hetero-KO and the control wild-type mice in adulthood and old age months. Among the genes whose expression level was down-regulated in the aged wild-type mice, 341 genes were down-regulated in the adulthood Rp58 hetero-KO mice when both were compared with the adulthood wild-type mice. Conversely, the expression levels of 103 genes were up-regulated both in the adulthood Rp58 hetero-KO and the aged wild-type mice. In the pathway enrichment analysis, these 103 up-regulated genes included Cxcl10, Oas2, Oas1a, and Oasl2, which are associated with a pathway of immune response interferon gamma action on extracellular matrix and cell differentiation.

Targeting Cancer Associated Fibroblasts/Tumor Cells Cross-Talk Inhibits Intrahepatic Cholangiocarcinoma Progression

Project description:Cancer associated fibroblasts (CAFs), mainly responsible for the desmoplastic reaction hallmark of intrahepatic Cholangiocarcinoma (iCCA), likely take a role in tumour aggressiveness and resistance to therapy, although the molecular mechanisms involved are unknown. Aim of the study is to investigate how targeting hCAF/iCCA cross-talk with a Notch1 inhibitor namely Crenigacestat would affect cancer progressionWe used different in vitro models in 2D and we established new 3D hetero-spheroids with iCCA cells and human (h)CAFs. Results were confirmed in a xenograft model, explanted tumoral tissues underwent transcriptomic and bioinformatic analysis. hCAFs/iCCA cross-talk sustains increased migration of both KKU-M213 and KKU-M156 cells, while Crenigacestat significantly inhibits only the cross-talk stimulated migration. Hetero-spheroids grow larger than homo-spheroids,formed by only iCCA cells. Crenigacestat significantly reduced invasion and growth of hetero- but not of homo-spheroids. In xenograft models, hCAFs/KKU-M213 tumours grew significantly larger than KKU-M213 tumours, but were significantly reduced in volume by Crenigacestat treatment, which also significantly reduced the fibrotic reaction. Interpretative phenomenological analysis of the transcriptome unveiled that genes of hCAFs/KKU-M213 but not of KKU-M213 tumours increased tumour lesions, and that Crenigacestat treatment inhibited the modulated canonical pathway. Cell cycle checkpoints were the most modulated pathway. In hetero-spheroids, the number of cells increased into G2/M cell cycle phase, while Crenigacestat significantly decreased the number into G2/M phase in hetero but not in homo-spheroids. The cross-talk hCAFs/iCCA is a new target for reducing cancer progression with drugs such as Crenigacestat.

Microarray expression profiling of the Igf2 pathway dependency of Trp53 developmental and tumour phenotypes in mice

Project description:We tested whether loss of p53 function leads to insulin-like growth factor 2 (IGF2) pathway dependency in vivo in genetically defined mouse models. Unexpectedly we found lethality, due to post-natal lung haemorrhage, occurred in Igf2 paternal null allele female mice (Igf2-p) but only if derived from double heterozygote fathers (Igf2-p, p53+/-). Consequently we investigated the effects of paternal genotype (wild-type, Igf2-p and Igf2-p, p53+/-) on gene expression. Microarray gene expression profiling of whole mouse embryos (embryonic day 9.5) revealed that lethality was associated with a specific gene signature. Since double heterozygote female offspring (Igf2-p, p53+/-) of Igf2-p, p53+/- fathers did not have the lethality phenotype we identified gene expression changes associated with this 'rescue'.

RNA-Sequencing analysis of liver tissue from female Foxa3-Cre YAP1 knockout mice, Foxa3-Cre YAP1 KO TAZ heterozygous mice, and WT littermate controls, at 3-4 months of age

Project description:We developed a mouse model of bile duct paucity by deleting Yes-associated protein 1 (YAP1) in foregut endoderm progenitors, using the Foxa3 promoter to drive Cre expression. YAP1 KO mice are viable postnatally and survive long-term despite a complete failure of intrahepatic bile duct development, resembling the liver phenotype of Alagille syndrome. Adult YAP1 KO mice suffer from severe chronic cholestasis, but show minimal hepatocellular injury, suggesting that the hepatocytes have adapted to preserve liver function and reduce damage from the toxicity of bile acids and bilirubin. We next bred Foxa3-Cre YAP1 KO TAZ heterozygote and Foxa3-Cre YAP1 KO TAZ KO (DKO) mice to assess the role of TAZ in this model. DKO mice and male YAP KO TAZ heterozygotes died around time of birth. The survivors, YAP1 KO TAZ heterozygote females, were overall phenotypically similar to YAP1 KO mice, with absence of intrahepatic bile ducts and long-term survival. We used RNA-seq to analyze the gene expression patterns of whole liver tissue of female adult YAP1 KO mice compared to WT controls (C57BL/6 background), and female adult YAP1 KO TAZ heterozygote (YKTH) mice compared to WT controls (mixed C57BL/6 - FVB background). We found that both YAP1 KO and YAP1 KO TAZ heterozygote female mice were overall very similar and showed similar alterations in gene expression compared to WT. There were a few differences in pathways involved in cell cycling and monocyte recruitment.

Differential Gene expression in the mouse mammary tumors of PyMT-Malat1 wild-type (WT), PyMT-Malat1 knockout (KO) and PyMT-Malat1 knockout with Malat1 transgene expression (TG)

Project description:Previously, lncRNA Malat1 knockout mice were generated by insertional inactivation. By crossing this line to MMTV-PyMT mammary tumor mouse model, we produced PyMT;Malat1 wild-type (WT) and PyMT;Malat1 knockout (KO). Furthermore, we generated Malat1 transgenic mice by targeting ROSA26 locus and bred them to PyMT;Malat1 knockout mice to produce Malat1-rescued PyMT;Malat1 knockout;Malat1 transgenic animals (TG). Using mammary tumors from the three groups of animals, we performed RNA-Seq analysis to identify differentially up-regulated genes in KO tumors to find novel target genes of YAP-TEAD pathway.
