The divergent nodes of non-autonomous UPRER signaling through serotonergic and dopaminergic neurons

ABSTRACT: Performed RNA-seq analysis of animals with xbp-1s overexpression (ER stress response transcription factor) in specific neuron types: pan-neuronal, serotonergic neuron, dopaminergic neuron, and both serotonergic and dopaminergic neurons, all compared to a wild-type control. RNA-seq was performed on purified RNA extracted from ~1000 whole worms using a proprietary Genewiz protocol described briefly in the manuscript. 3 biological replicates are provided for each sample.

Transcription profiling of mouse multiple myeloma tumors and splenic B cells from transgenics overexpressing XBP-1s

Project description:Multiple myeloma (MM) evolves from highly prevalent premalignant condition termed Monoclonal Gammopathy of Undetermined Significance (MGUS). We report an MGUS-MM phenotype arising in transgenic mice with Emu-directed expression of the unfolded protein/ER stress response and plasma cell development spliced isoform factor XBP-1s. Emu-XBP-1s elicited elevated serum Ig and IL-6 levels, skin alterations and with advancing age, a significant proportion of Emu-xbp-1s transgenic mice develop features diagnostic of human MM including bone lytic lesions. Transcriptional profiles of Emu-xbp-1s B lymphoid and MM cells show aberrant expression of genes known to be dysregulated in human MM including Cyclin D1, MAF, MAFB, and APRIL. This genetic model coupled with documented frequent XBP-1s overexpression in human MM serve to implicate chronic XBP-1s dysregulation in the development of this common and lethal malignancy. Experiment Overall Design: In this study, we have explored the biological impact of sustained XBP-1s expression in the lymphoid system, anticipating that this genetic event would be a necessary component along with other MM-relevant oncogenes and tumor suppressor gene manipulations to generate a MM-prone mouse model. Unexpectedly, XBP-1s overexpression alone yielded an MGUS-MM disease bearing many features classical of the human disease on the clinical, pathological and molecular levels. Experiment Overall Design: We performed expression analysis of B cells derived from the spleen of 20-week old Emu-xbp-1s mice (n=5) and non-transgenic mice (n=5). Additionally, we analyzed the expression profiles from MM tumor cells arising in Emu-xbp-1s mice (n=6).

An Elongin-Cullin-SOCS-box Complex Regulates Stress-induced Serotonergic Neuromodulation Stress-induced Serotonergic Neuromodulation

Project description:Neuromodulatory cells transduce environmental information into long lasting behavioral responses. However, the mechanisms governing how defined neuronal cell types influence behavioral plasticity are difficult to characterize. Here we adapted the Translating Ribosome Affinity Purification (TRAP) approach in C. elegans to profile ribosome-associated mRNAs from three major tissues and the neuromodulatory dopaminergic and serotonergic cells. We identified elc-2, an Elongin C ortholog, specifically expressed in stress-sensing ADF serotonergic sensory neurons, and found that it plays a role in mediating long-lasting change in serotonin-dependent feeding behavior induced by heat stress. We demonstrate that ELC-2 and the von Hippel-Lindau protein VHL-1, components of an Elongin-Cullin-SOCS-box (ECS) E3 ubiquitin ligase, modulate this behavior after experiencing stress. Also, heat stress induces a transient redistribution of ELC-2, becoming more nuclearly enriched. Together, our results demonstrate dynamic regulation of an E3 ligase, and a role for an ECS complex in neuromodulation and control of lasting behavioral states.

Establishment of a dopaminergic neuron purification system in mice

Project description:Transcriptomic analysis of enriched of neuron population collected from in-vivo mouse brains has been a challenge in the neuroscience field due to its fragility in withstanding harsh condition during isolation and collection process. We established a fluorescent reporter mouse Ddc-hKO1 to facilitate the identification and collection of Ddc-expressing neurons (dopaminergic, serotonergic, cholinergic and adrenergic neurons) by the detection of red fluorescence signals using a FACs. We utilized an improved isolation protocol that ensure high yield and quality of viable neurons during collection that is suitable for RNA-sequencing. This is the first report of transcriptomic profiling of Ddc expressing (hKO1(+)) neurons. Successful collection of Ddc-expressing neurons were verified by gene markers of dopaminergic, serotonergic, cholinergic neurons in hKO1(+) populations while other neuron types in hKO1(-) population. Furthermore, GSEA analysis were performed on both hKO1(+) and hKO1(-) to further support the neuron types collected in respective population.

Neuronal deletion of the circadian clock gene Bmal1 induces cell-autonomous dopaminergic neurodegeneration

Project description:Circadian rhythm dysfunction is a hallmark of Parkinson Disease (PD), and diminished expression of the core clock gene Bmal1 has been described in PD patients. BMAL1 is required for core circadian clock function, but also serves non-rhythmic functions. Germline Bmal1 deletion can cause brain oxidative stress and synapse loss in mice, and can exacerbate dopaminergic neurodegeneration in response to MPTP. Here we examined the impact of cell type-specific Bmal1 deletion on dopaminergic neuron viability in vivo. We observed that global, post-natal deletion of Bmal1 caused spontaneous loss of tyrosine hydroxylase-positive (TH+) dopaminergic neurons in the substantia nigra pars compacta (SNpc). This was not due to disruption of behavioral circadian rhythms, and was not induced by astrocyte- or microglia-specific Bmal1 deletion. However, either pan-neuronal or TH neuron-specific Bmal1 deletion caused cell-autonomous loss of TH+ neurons in the SNpc. Finally, global Bmal1 deletion exacerbated TH+ neuron loss following injection of alpha-synclein fibrils. Transcriptomic analysis of neuron-specific Bmal1 KO brain revealed dysregulation of pathways involved in oxidative phosphorylation and Parkinson Disease.

Transcriptional profiling of human serotonergic neurons in vitro

Project description:Human serotonergic neurons are derived using published transdifferentiation protocols. Human Fibroblasts correspond to human fibroblasts (from Line#1, Coriell bought (AG08498)). Samples labeled human neurons or induced neurons (iN) correspond to neurons transdifferentiated from fibroblasts using two transcription factors, as previously described (#1-AG08498 or #2:ERF-1, Erlangen Germany, a line given to us by collaborators) into primarily glutamatergic neruons. Samples labled 5-HT neurons or serotonergic neurons or iSN correspond to serotonergic neurons derived from the stated fibroblast lines, using an additional four transcription factors. For transdifferentiation of iN and iSN, fibroblasts were made to overexpress the stated transcription factors in a doxycycline inducible manner for up to 3 weeks, and then neurons are sorted out and collected directly into Trizol for RNA preparation and sequencing. The non-transdifferentiated fibroblast lines were collected in bulk withtout differentiation into neurons. The line number corresponds to the same fibroblast line either being transdifferentiated into iN or iSN, as labeled - for direct and groupwise comparison.
