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_19241	regulation of_lipid_metabolism_by_peroxisome_proliferator_activated_receptor_alpha	Peroxisome proliferator-activated receptor alpha (PPAR-alpha...... Peroxisome proliferator-activated receptor alpha (PPAR-alpha) is the major regulator of fatty acid oxidation in the liver. PPARalpha is also the target of fibrate drugs used to treat abnormal plasma lipid levels. PPAR-alpha is a type II nuclear receptor (its subcellular location does not depend on ligand binding). PPAR-alpha forms heterodimers with Retinoid X receptor alpha (RXR-alpha), another type II nuclear receptor. PPAR-alpha is activated by binding fatty acid ligands, especially polyunsaturated fatty acids having 18-22 carbon groups and 2-6 double bonds. The PPAR-alpha:RXR-alpha heterodimer binds peroxisome proliferator receptor elements (PPREs) in and around target genes. Binding of fatty acids and synthetic ligands causes a conformational change in PPAR-alpha such that it releases the corepressors and binds coactivators (CBP-SRC-HAT complex, ASC complex, and TRAP-Mediator complex) which initiate transcription of the target genes. Target genes of PPAR-alpha participate in fatty acid transport, fatty acid oxidation, triglyceride clearance, lipoprotein production, and cholesterol homeostasis. More...
REACT_602	metabolism of_lipids_and_lipoproteins	Lipids are hydrophobic but otherwise chemically diverse mole...... Lipids are hydrophobic but otherwise chemically diverse molecules that play a wide variety of roles in human biology. They include ketone bodies, fatty acids, triacylglycerols, phospholipids and sphingolipids, eicosanoids, cholesterol, bile salts, steroid hormones, and fat-soluble vitamins, and function as a major source of energy (fatty acids, triacylglycerols, and ketone bodies), are major constituents of cell membranes (cholesterol and phospholipids), play a major role in their own digestion and uptake (bile salts), and participate in numerous signaling and regulatory processes (steroid hormones, eicosanoids, and sphingolipids). Because of their poor solubility in water, most lipids in extracellular spaces in the human body are found as complexes with specific carrier proteins. Regulation of the formation and movement of these lipoprotein complexes is a critical aspect of human lipid metabolism, and lipoprotein abnormalities are associated with major human disease processes including atherosclerosis and diabetes. Aspects of lipid metabolism currently annotated in Reactome include lipid digestion, trafficking of dietary sterols, triacylglycerol synthesis (fatty acid synthesis and triacylglycerol assembly), hormone-sensitive lipase-mediated triacylglycerol breakdown, and beta-oxidation of fatty acids, ketone body metabolism (synthesis and utilization), the synthesis of cholesterol, bile salts, and steroid hormones, and sphingolipid metabolism. Three aspects of lipoprotein function are currently annotated: chylomicron-mediated lipid transport, HDL (high density lipoprotein)-mediated lipid transport, and LDL (low density lipoprotein) endocytosis and degradation.
