Gene expression difference between normal and Pten-deficient 5-HT neurons

ABSTRACT: Purpose: compare the gene expression diffenrence between wildtype and Pten-deficient 5-HT neurons. Methods: 5-HT neurons cell body are collected from acut brain slice with patch electrodes. Pten-deficient 5-HT neurons are obtained from Pet1-Cre; Ptenflox/flox mice. Normal 5-HT neurons are obtained from littermate wildtype mice. Reverse transcription was performed using a SMARTer Ultra Low RNA Kit (Clontech, Japan). Single-cell cDNA was amplified using an Advantage 2 PCR Kit (Clontech, Japan). Purified cDNA from individual cells were sequenced using the Illumina HiSeq 2000 platform. Sequence reads were aligned to the mouse mm9 genome using TopHat. Differential expression analysis was performed using DESeq (Bioconductor) followed by Student t-test. Genes were considered differentially expressed if p<0.05. Results: The somatic compartments of individual YFP-labeled 5-HT neurons in acute brain slices were harvested for RNA sequencing. Each of the cells had 2 X 107 reads mapping back to the mouse genome when analyzed using the RUM mapping program. We found 859 genes (381 up-regulated, 478 down-regulated) were differentially expressed in Pten-deficient 5-HT neurons. Gene ontology of differentially expressed genes revealed the biological processes up-regulated and down-regulated in Pten-deficient 5-HT neurons. The absence of Pten in 5-HT neurons was associated with significantly increased expression of genes involved in the regulation of axonal extension and cell size, cell morphogenesis and cytoskeleton organization

Synthetic essentiality of metabolic regulator PDHK1 in PTEN-deficient cells and cancer

Project description:PTEN is a tumor suppressor that is often inactivated in cancer and possesses both lipid and protein phosphatase activities. We report the metabolic regulator PDHK1 (pyruvate dehydrogenase kinase1) is a synthetic-essential gene in PTEN-deficient cancer and normal cells. The predominant mechanism of PDHK1 regulation and dependency is the PTEN protein phosphatase dephosphorylates NFkB activating protein (NKAP) and limits NFkB activation to suppress expression of PDHK1, a NFkB target gene. Loss of the PTEN protein phosphatase upregulates PDHK1 to drive aerobic glycolysis and induce PDHK1 cellular dependence. PTEN-deficient human tumors harbor increased PDHK1, which is a biomarker of decreased patient survival, establishing clinical relevance. This study uncovers a PTEN-regulated signaling pathway and reveals PDHK1 as a potential target in PTEN-deficient cancers.

PTEN phosphatase inhibits metastasis

Project description:PTEN encodes a tumor suppressor with lipid and protein phosphatase activities whose dysfunction has been implicated in melanomagenesis; less is known about how its phosphatases regulate melanoma metastasis. We show that PTEN expression negatively correlates with metastatic progression in human melanoma samples and a PTEN-deficient mouse melanoma model. Wildtype PTEN expression inhibited melanoma cell invasiveness and metastasis in a dose-dependent manner, behaviors that specifically required PTEN protein phosphatase activity. PTEN phosphatase activity regulated metastasis through Entpd5. Entpd5 knockdown reduced metastasis and IGF1R levels while promoting ER stress. In contrast, Entpd5 overexpression promoted metastasis and enhanced IGF1R levels, while reducing ER stress. Moreover, Entpd5 expression was regulated by the ER stress sensor ATF6. Altogether, our data show that PTEN phosphatase activity inhibits metastasis by negatively regulating the Entpd5/IGF1R pathway through ATF6, thereby identifying novel candidate therapeutic targets for the treatmtreatingwith PTEN mutant melanoma.

The phosphatase PTEN links platelets with immune regulatory functions of mouse T follicular helper cells

Project description:Beyond a function in hemostasis and thrombosis, platelets can regulate innate and adaptive immune responses. Hyperactive platelets are frequently associated with multiple human autoimmune diseases, yet their pathogenic functions in these diseases have not been fully established. Emerging studies show an essential function of the phosphatase and tensin homolog (PTEN) in maintenance of immune homeostasis. Here, we show that mice with platelet-specific deletion of Pten, develop age-related lymphoproliferative diseases and humoral autoimmunity not seen in wildtype animals. Platelet-specific Pten-deficient mice have aberrant T cell activation, excessive T follicular helper (Tfh) cell responses and accumulation of platelet aggregates in lymph nodes. Transferred Pten-deficient platelets are able to infiltrate into the peripheral lymphoid tissues and form more aggregates. Moreover, Pten-deficient platelets are hyperactive and overproduce multiple Tfh-promoting cytokines via activation of the PDK1/mTORC2-AKT-SNAP23 pathway. Pten-deficient platelets show enhanced interaction with CD4+ T cells and promote conversion of CD4+ T cells into Tfh cells. Our results implicate PTEN in platelet-mediated immune homeostasis, and provide evidence that hyperactive platelets function as an important mediator in autoimmune diseases using mouse models.

Global proteome of Atg16L1flox:CAG-CreTmx WT and KO neurons

Project description:The experiment was performed to identify autophagy targets in wildtype and autophagy-deficient primary neurons. Therefore, cortico-hippocampal neurons were isolated from Atg16L1flox:CAG-CreTmx mice and treated with Tamoxifen (Tmx) to induce the knockout (KO) or EtOH for wildtype (WT) in-vitro. WT and KO Neurons were harvested at day in-vitro (DIV) 15-16, and global proteome analysis was measured by LC-MS/MS.

Generation of caudal-type serotonin neurons and hindbrain fate organoids from hPSCs

Project description:Serotonin (5-HT) neurons, the major components of the raphe nuclei, arise from ventral hindbrain progenitors. Based on the anatomical location and axonal projection, 5-HT neurons are coarsely divided into rostral and caudal groups. Here, we propose a novel strategy to generate hindbrain 5-HT neurons from human pluripotent stem cells (hPSCs), which involves the formation of ventral-type neural progenitor cells (NPCs) and stimulation of the hindbrain 5-HT neural development. A caudalizing agent, retinoid acid (RA), was used to direct the cells into the hindbrain cell fate. Approximately 30-40% of hPSCs successfully developed into 5-HT-expressing neurons using our protocol, with the majority acquiring a caudal rhombomere identity (r5-8). We further modified our monolayer differentiation system to generate 5-HT neuron-enriched hindbrain-like organoids. We have also suggested downstream applications of our 5-HT monolayer and organoid cultures to study neuronal response to gut microbiota. Our methodology could become a powerful tool for future studies related to 5-HT neurotransmission.
