Project description:We identify a new mechanism by which OLZ ameliorates chronic stress-enhanced tumorigenesis and chemoresistance. OLZ reversed chronic stress-enhanced lung tumorigenesis and anxiety-like behaviors by suppressing neuro-activity in the mPFC and reducing norepinephrine (NE) releasing. To investigate the mechanism of NE in cancer stemness we performed RNA-seq of the NCI-H1299 cells under NE treatment and found that NE activated β2-adrenoceptor (ADRB2)-mediated cAMP-PKA-CREB pathway to transactivate CLOCK that further sustains cancer stemness.

Project description:Background: The goal of this study was to determine the transcriptional consequences of norepinephrine transporter (NET) gene deletion in noradrenergic neuron differentiation. The norepinephrine transporter (NET) is the target of powerful mind-altering substances, such as tricyclic antidepressants and the drug of abuse, cocaine. NET function in adult noradrenergic neurons of the peripheral and central nervous systems is that of a scavenger that internalizes norepinephrine from the synaptic cleft. By contrast, norepinephrine (NE) transport has a different role in embryogenesis. It promotes differentiation of neural crest cells and locus ceruleus progenitors into noradrenergic neurons, whereas NET inhibitors, such as the tricyclic antidepressant desipramine and the drug of abuse, cocaine, inhibit noradrenergic differentiation. While NET structure und regulation of NET function is well described, little is known about downstream targets of NE transport. Results: We have determined by long serial analysis of gene expression (LongSAGE) the gene expression profiles of in vitro differentiating wild type and norepinephrine transporter-deficient (NETKO) neural crest derivatives. Comparison analyses with the wild type library (GSM 105765) have identified a number of important differentially expressed genes, including genes relevant to noradrenergic neuron differentiation and to the phenotype of NETKO mice. Furthermore we have identified novel differentially expressed genes. Conclusions: Loss of NET function during embryonic development deregulates signaling pathways that are critically involved in neural crest formation and noradrenergic neuron differentiation. The library was constructed from total RNA of 60 neural crest culture at culture day 7. The neural tubes were dissected from E9.5 embryos that lack the norepinephrine transporter gene.

Project description:Chronic pain is a major health care problem with great social and economic consequences. Although the medial prefrontal cortex (mPFC) and the thalamus have been implicated in regulating pain, whether and how these regions may involve in pain chronification process have remained largely unknown. Here, we show that Foxp2+ neurons in mPFC, which are corticothalamic (CT) neurons representing the major mPFC output to thalamus, are deactivated in chronic inflammatory pain. Interestingly, prolonged, but not short-term, inactivation of the Foxp2+ neurons in mPFC increases the sensitivity to noxious stimulations. Conversely, chemogenetic activation of this neuronal cluster induces robust antinociceptive effects in both naïve mice and mice with chronic inflammatory pain. Furthermore, we found that the mPFC Foxp2+ neurons project to several thalamic relay nuclei and that activation of the mPFC to the parataenial nucleus of thalamus (PTN) circuit relieves pain. Finally, RNA-seq of the mPFC Foxp2+ neurons revealed that many genes related to neuronal activity are dysregulated in mice with chronic inflammatory pain. Collectively, our studies revealed that Foxp2+ neurons in mPFC that project to thalamus play a critical role in somatosensory processing and pain chronification.

Project description:Chronic stress is associated with hormonal alterations that are known to promote cancer progression. The stress hormone norepinephrine promotes migration and metastasis of prostate cancer cells. Focal adhesion kinase (FAK) is a non-receptor protein tyrosine kinase which is phosphorylated during chronic stress or norepinephrine treatment. Here, we investigated how norepinephrine modulates the gene expression in Myc-CaP prostate cancer cell line. We also focused on the effect of FAK knockdown in norepinephrine-induced changes of the gene expression profile.

Project description:The heterogeneity of cortical dopamine D2 receptor expressing cells is not well characterized We performed microarrays to study expression of all the transcriprts specifically from Drd2+ neurons of mouse mPFC. For this we immunoprecipitated ribosomes from mPFC of D2Cre::RiboTag mouse, where ribosomal subunit Rpl22 is tagged with HA epitope specifically in Drd2+ neurons

Project description:Gene expression profiling was carried out HeyA8 and SKOV3-ip1 ovarian cancer cell lines, treated either with vehicle control or 10 uM norepinephrine. The primary research question is whether ovarian cancer cell gene expression differs as a function of norepinephrine exposure. Gene expression profiling was carried out HeyA8 and SKOV3-ip1 ovarian cancer cell lines, treated either with vehicle control or 10 uM norepinephrine.

Project description:Our research showed that astrocytic OGT could influence the expression of proteins in the mPFC. Most of these altered proteins participate in metabolic process, transferase activity, and biosynthetic process. GFAP, an astrocyte maker, was increased after OGT deletion. These results provide a framework for further study on the role of astrocytic OGT/O-GlcNAcylation in the mPFC.
