PDE4B	Numata, 2009	patients and normal controls	P-value < 0.0001	In the leukocytes, a significantly higher expression of the ...... In the leukocytes, a significantly higher expression of the PDE4B mRNA was observed in the drug-naive MDD patients compared with control subjects (P < 0.0001); In the association analysis, we observed significant allelic associations of four SNPs (the most significant, rs472952; P = 0.002) and a significant haplotypic association (permutation P = 0.019) between the PDE4B gene and MDD in the first-set samples.

Positive relationship network of PDE4B in MK4MDD

Network loading ...

Note:
1. The different color of the nodes denotes the level of the nodes.

Genetic/Epigenetic Locus	Protein and Other Molecule	Cell and Molecular Pathway	Neural System	Cognition and Behavior	Symptoms and Signs	Environment	MDD

2. Besides the component related relationships from literature, gene mapped protein and protein mapped gene are also shown in the network. If the mapped gene or protein is not from literature, square node would be used instead of Circle node. Accordingly, the relationship is marked with dot line.
2. User can drag the nodes to rearrange the layout of the network. Click the node will enter the report page of the node. Right-click will show also the menus to link to the report page of the node and remove the node and related edges. Hover the node will show the level of the node and hover the edge will show the evidence/description of the edge.
3. The network is generated using Cytoscape Web

REACT_15295	opioid signalling	Opioids are chemical substances similar to opiates, the acti...... Opioids are chemical substances similar to opiates, the active substances found in opium (morphine, codeine etc.). Opioid action is mediated by the receptors for endogenous opioids; peptides such as the enkephalins, the endorphins or the dynorphins. Opioids possess powerful analgesic and sedative effects, and are widely used as pain-killers. Their main side-effect is the rapid establishment of a strong addiction. Opioids receptors are G-protein coupled receptors (GPCR). There are four classes of receptors: mu (MOR), kappa (KOR) and delta (DOR), and the nociceptin receptor (NOP). More...
REACT_15334	darpp32 events	Dopamine- and cAMP-regulated phosphoprotein, Mr 32 kDa (DARP...... Dopamine- and cAMP-regulated phosphoprotein, Mr 32 kDa (DARPP-32), was identified as a major target for dopamine and protein kinase A (PKA) in striatum. Recent advances now indicate that regulation DARPP-32 phosphorylation provides a mechanism for integrating information arriving at dopaminoceptive neurons, in multiple brain regions, via a variety of neurotransmitters, neuromodulators, neuropeptides, and steroid hormones. Activation of PKA or PKG stimulates DARPP-32 phosphorylation at Thr34, converting DARPP-32 into a potent inhibitor of protein phosphatase-1 (PP-1). DARPP-32 is also phosphorylated at Thr75 by Cdk5, converting DARPP-32 into an inhibitor of PKA. Thus, DARPP-32 has the unique property of being a dual-function protein, acting either as an inhibitor of PP-1 or of PKA. More...

The general function of the G alpha (s) subunit (Gs) is to activate adenylate cyclase, which in turn produces cAMP, leading to the activation of cAMP-dependent protein kinases (often referred to collectively as Protein Kinase A). The signal from the ligand-stimulated GPCR is amplified because the receptor can activate several Gs heterotrimers before it is inactivated. More...
REACT_19184	downstream events_in_gpcr_signaling	G protein-coupled receptors. The beta:gamma G-protein dimer ...... G protein-coupled receptors. The beta:gamma G-protein dimer is also involved in downstream signaling , and some receptors form part of metastable complexes of receptor and accessory proteins such as the arrestins. GPCRs are involved in many diverse signaling events , using a variety of pathways that include modulation of adenylyl cyclase, phospholipase C, the mitogen activated protein kinases (MAPKs), extracellular signal regulated kinase (ERK) c-Jun-NH2-terminal kinase (JNK) and p38 MAPK.
