Transcriptomic analysis of defense responses in Arabidopsis thaliana wild-type and mammalian guanylate cyclase-expressing transgenic plants in response to infection with an avirulent strain of Pseudomonas syringae pv. tomato

ABSTRACT: 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.

Phosphatidic acid governs natural egress in Toxoplasma gondii via a guanylate cyclase receptor platform

Project description:Toxoplasma gondii is able to establish a life-long chronic infection in human and animals. Host cell entry and egress from infected cells are two key steps in the lytic cycle of this obligate intracellular parasite that ensures its survival and dissemination. Egress is a temporally orchestrated process underpinned by the regulated exocytosis of the apical secretory organelles, termed micronemes. At any point during intracellular replication, deleterious environmental changes resulting from a loss of host cell integrity can trigger egress via the activation of the cGMP-dependent protein kinase G (PKG). Remarkably, even in the absence of extrinsic alarming signals, the parasites naturally egress from infected cells in a coordinated manner after ca. 5 to 6 cycles of binary fission. Here we show that diacylglycerol kinase 2 (DGK2) is secreted into the parasitophorous vacuole where it produces phosphatidic (PA), which acts as intrinsic signal to elicit natural egress. PA activates a large guanylate cyclase (GC) receptor uniquely conserved in apicomplexans and composed of one P4-ATPase and two guanylate cyclase domains. Assembly of a functional GC at the parasite plasma membrane critically depends on the association with two proteins acting as cofactors. This study reveals the existence of a unique and versatile signaling platform able to respond to an intrinsic lipid mediator and other extrinsic alarming signals to control programmed and induced egress, respectively.

Treatment effects of soluble guanylate cyclase modulation on diabetic kidney disease at single-cell resolution

Project description:Diabetic kidney disease (DKD) is the most common cause of renal failure. Therapeutics development is hampered by our incomplete understanding of animal models on a cellular level. We show that ZSF1 rats recapitulate human DKD on a phenotypic and transcriptomic level. Tensor decomposition prioritizes proximal tubule (PT) and stroma as phenotype-relevant cell types exhibiting a continuous lineage relationship. As DKD features endothelial dysfunction, oxidative stress, and nitric oxide depletion, soluble guanylate cyclase (sGC) is a promising DKD drug target. sGC expression is specifically enriched in PT and stroma. In ZSF1 rats, pharmacological sGC activation confers considerable benefits over stimulation and is mechanistically related to improved oxidative stress regulation, resulting in enhanced downstream cGMP effects. Finally, we define sGC gene co-expression modules, which allow stratification of human kidney samples by DKD prevalence and disease-relevant measures such as kidney function, proteinuria, and fibrosis, underscoring the relevance of the sGC pathway to patients.

Loss of soluble guanylate cyclase, the major nitric oxide receptor, leads to moyamoya and achalasia.

Project description:Background: Moyamoya is a cerebrovascular condition of unknown mechanism characterized by a progressive stenosis of the terminal part of the internal carotid arteries (ICA) and the compensatory development of abnormal “moyamoya” vessels. It leads to ischemic and hemorrhagic stroke. We describe a novel autosomal recessive disease leading to severe moyamoya and early onset achalasia and report its cause in 3 unrelated families. Methods: We used a combination of genetic linkage and exome sequencing in 2 consanguineous to identify rare shared variants. Sanger sequencing of GUCY1A3, the sole gene mutated in both families, was then conducted in the third family. Platelets from one of the patients and controls were used to carry out functional studies. Results: Homozygous mutations of GUCY1A3 gene encoding the alpha1 subunit of soluble guanylate cyclase (sGC), the major receptor for Nitric Oxide (NO), were identified in all 3 families. Platelet analysis showed a complete loss of the mutated protein and showed an unexpected stimulatory role of sGC within platelets. Conclusion: The NO/sGC/cGMP pathway is a major pathway controlling vascular smooth muscle (VSMC) relaxation, vascular tone and vascular remodeling. Our data suggest that alterations of this pathway may lead to an abnormal vascular remodeling process in sensitive vascular areas with low blood

Transcription profiling of human soluble guanylate cyclase-deficient U937 cells exposed to the nitric oxide (NO) donor S-nitrosoglutathione to provide insight into the cGMP-independent effects of NO

Project description:NO effects on gene expression, independent of cGMP, were examined globally. Differentiated human U937 cells that lack soluble guanylate cyclase were exposed to Snitrosoglutathione, a NO donor, or glutathione without or with dibutyryl-cAMP (Bt2cAMP). NO regulated 110 transcripts that annotated disproportionately to the cell cycle and cell proliferation (47/110, 43%) and more frequently than expected contained AU-rich, post-transcriptional regulatory elements (ARE). Bt2cAMP regulated 106 genes; cell cycle gene enrichment did not reach significance. Like NO, Bt2cAMP was associated with ARE-containing transcripts. Cell cycle genes induced by NO were G1/S phase associated (7/8) including E2F1 and p21/Waf1/Cip1; 6 of these 7 were E2F target genes involved in G1/S transition. Repressed genes were G2/M associated (24/27); 8 of 27 were known targets of p21. E2F1 mRNA and protein were increased by NO, as was E2F1 binding to E2F promoter elements. NO activated p38 MAPK, stabilizing p21 mRNA and increasing p21 protein. Subsequent increases in protein binding to CDE/CHR sites repressed key G2/M phase genes and increased the proportion of cells in G2/M. Thus, NO triggers a specific and coordinated program of cell cycle arrest independent of cGMP. Stress kinase pathways and mRNA stability are major mechanisms by which NO regulates the transcriptome.

Genes regulated by soluble guanylyl cyclase in VCaP prostate cancer cells

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.
