Project description:In bacteria, Crp-Fnr superfamily transcription factors mediate 3',5'-cyclic adenosine monophosphate (cAMP) and 3',5'-cyclic guanosine monophosphate (cGMP) signaling. The CRP-like protein Clr of the soil-dwelling and plant-symbiotic α-proteobacterium Sinorhizobium meliloti was previously shown to activate target promoters in both its cAMP- and cGMP-bound states (Krol et al., Microbiology 62:1840–1856, 2016). In order to further characterize the overall regulon of Clr in S. meliloti Chromatin Immuno Precipitation DNA-Sequencing (ChIP-Seq) experiments were performed with C-terminally FLAG tagged Clr under four different growth conditions, namely growth in TY complex medium and MOPS minimal medium, each supplemented with either cAMP or cGMP. For each condition, the respective immunoprecipitated (IP) and non-immunoprecipitated (control) samples were analyzed and compared to locate genomic positions in which Clr-DNA binding occurs. In combining ChIP-Seq with Electrophoretic Mobility Shift Assays and promoter-probe assays we expanded the list of known Clr-regulated target promoters and showed that virtually all of these promoters containing a palindromic Clr binding site (CBS) motif are activated both by Clr•cAMP and Clr•cGMP.

Project description:cGMP is well-known secound messanger involved in vascular homeostasis. However little is known the effect of cGMP inducer on mRNA expression in cancer cells. We performed microarrays to revealed the transcriptional change of a human pancreatic ductal adenocarcinoma (PDCA) cell line (Panc -1) to cGMP inducer Bay41-2272 in order to provide insight into impact of cGMP induction on Panc-1 cells. Panc-1 Human PDCA cells were treated with vehicle (DMSO) or 5 μM Bay41-2272 for 48 h and total RNA was extracted by using TRIzol Reagent. The microarray analysis was conducted on the Panc-1 cells expressing by using Agilent Microarray.

Project description:Responses to social cues, such as pheromones, can be modified by genotype, physiology, or environmental context. Honey bee queens produce a pheromone (queen mandibular pheromone; QMP) which regulates many aspects of worker bee behavior and physiology. Forager honey bees are less responsive to QMP than young nurse bees engaged in brood care, suggesting that physiological changes associated with behavioral maturation may modulate response to this pheromone. Since cGMP is a major regulator of behavioral maturation in honey bee workers, we examined its role in modulating worker responses to QMP. Treatment with a cGMP analog, 8-Br-cGMP, resulted in significant reductions in both behavioral and physiological responses to QMP in young caged workers. Treatment significantly reduced attraction to QMP (the retinue response) and inhibited the QMP-mediated increase in vitellogenin levels in the fat bodies of worker bees. Genome-wide analysis of brain gene expression patterns demonstrated that cGMP has a larger effect on expression levels than QMP, and that QMP has specific effects in the presence of cGMP, suggesting that some responses to QMP may be dependent on an individual beesM-^R physiological state. Several functional gene categories were significantly differentially expressed, including genes involved in regulating GTPase activity, phototransduction, immunity, and carboxylic acid transmembrane transporter activity. Overall, our data suggest that cGMP-mediated processes play a large role in modulating responses to queen pheromone in honey bees, at the behavioral, physiological and molecular levels.

Project description:The inherited eye disease Retinitis Pigmentosa (RP) causes the loss of photoreceptors by a still unknown cell death mechanism. During this degeneration, cGMP levels become elevated, leading to over-activation of the cGMP-binding protein cGMP-dependent protein kinase (PKG). cGMP analogs selectively modified to have inhibitory actions on PKG have aided in impeding photoreceptor death, and one such cGMP analog is Rp-8-Br-PET-cGMPS. However, cGMP analogs have previously been shown to interact with numerous targets, so to further evaluate Rp-8-Br-PET-cGMPS’ efficacy for therapies, it is necessary to comprehend its target-selectivity and what potential cellular mechanism(s) it may affect within the photoreceptors.

Project description:To decipher the role of cGMP during the hypersensitive response Arabidopsis thaliana transgenic lines have been produced which express a rat soluble guanylate cyclase. Transgenic plants display a higher constitutive amount of cGMP (4 to 50 fold) compared to wild-type. Both GC and wt genotypes were infected with PstAvrB and transcriptome profile was analyzed at 12 hours post-infection.

Project description:The aberrant activation of the ERG oncogenic pathway due to TMPRSS2-ERG gene fusions is the major driver of prostate cancer initiation and progression. We identified the alpha1 and beta1 subunits of soluble guanylyl cyclase (GUCY1A1, GUCY1B1) as major ERG-regulated genes in prostate cancer cells. Soluble guanylyl cyclase (sGC) is the major mediator of nitric oxide signaling in cells that, upon nitric oxide binding, catalyzes the synthesis of cGMP and subsequently activates PKG. We showed in ERG-positive PCa cells (VCaP) that cGMP synthesis was significantly elevated by ERG, leading to increased PKG activity and cell proliferation. To further understand the functions of sGC-cGMP pathway in prostate cancer cells, we performed RNA-seq analyses in VCaP cells to identify genes that are regulated by sGC.

Project description:Many forms of synaptic plasticity are critically dependent upon production of cGMP to trigger activity-dependent increases in synaptic size and strength. Phosphodiesterase 9A (PDE9A) is a high affinity, cGMP-specific phosphodiesterase with widespread distribution in the central nervous system. Inhibition of PDE9A results in significant accumulation of cGMP in brain tissue and cerebrospinal fluid (CSF) of rodents, and increases CSF cGMP in human volunteers. We hypothesized that chronic exposure to a PDE9A inhibitor, and the associated elevations in brain cGMP could provide a therapeutic benefit to vulnerable synapses chronically exposed to Aβ in transgenic mice over-expressing human mutant amyloid precursor protein (Tg2576 mice). A total of N=20 animals per group of 4 month old Tg2576 mice and non-transgenic littermates (WT) were implanted with Alzet osmotic minipumps to deliver vehicle or the PDE9A inhibitor PF-04447943. Neurobehavioral outcomes were measured as conditioned fear response after 28 days of treatment and subsequently brains were harvested for measurement of Aβ, gene expression profiling or synaptic density as assessed by Golgi staining of dendrites. Dendritic spine density on apical dendrites of CA1 neurons exhibited a small but significant deficit in the density of dendritic spines in vehicle treated Tg2576 mice as compared to WT mice. This deficit was ameliorated by 30 days of exposure to PF-04447943. No significant drug effect was observed in WT mice. No significant effects of drug treatment were observed on Aβ levels in Tg2576 mice. Behavioral analysis of Tg2576 mice showed deficits in fear conditioning as early as 2 months old, and therefore were considered unlikely to be due to the accumulation of oligomeric Aβ. These deficits were not affected by drug treatment. Transcriptional profiles of Tg2576 mice treated with drug compared to vehicle showed evidence of regulation of pathways related to synaptic plasticity and remodeling of the dendritic cytoskeleton, consistent with stabilization of vulnerable spine structure. These data supports the hypothesis that PDE9A inhibition can stabilize vulnerable synapses early in the Alzheimer’s disease process. 4-month old Tg2576 mice and non-transgenic (WT) littermates were implanted with minipumps to deliver vehicle or the PDE9A-inhibitor, PF-04447943, for 28 days. At the end of the study, hippocampus and frontal cortex were dissected from n=8 mice per group, RNA was isolated, and hybridized to Affymetrix 430 2.0 mouse whole genome microarray.

Project description:Expression profiling of honey bee brains as a function of treatments that accelerate the onset of foraging. Treatment groups included three treatments that accelerate the onset of foraging (methoprene [juvenile hormone analog], manganese, and cGMP) and two treatments that do not accelerate the onset of foraging (cAMP and vehicle control).
