Background: Acetyl-CoA carboxylase (ACC) catalyzes the carboxylation of acetyl-CoA to malonyl-CoA (1). It is the key enzyme in the biosynthesis and oxidation of fatty acids (1). In rodents, the 265 kDa ACC1 (ACCα) form is primarily expressed in lipogenic tissues, while 280 kDa ACC2 (ACCβ) is the main isoform in oxidative tissues (1,2). However, in humans, ACC2 is the predominant isoform in both lipogenic and oxidative tissues (1,2). Phosphorylation by AMPK at Ser79 or by PKA at Ser1200 inhibits the enzymatic activity of ACC (3). ACC is a potential target of anti-obesity drugs (4,5).

Background: The human retinoid X receptors (RXRs) are encoded by three distinct genes (RXRα, RXRβ, and RXRγ) and bind selectively and with high affinity to the vitamin A derivative, 9-cis-retinoic acid. RXRs are type-II nuclear hormone receptors that are largely localized to the nuclear compartment independent of ligand binding. Nuclear RXRs form heterodimers with nuclear hormone receptor subfamily 1 proteins, including thyroid hormone receptor, retinoic acid receptors, vitamin D receptor, peroxisome proliferator-activated receptors, liver X receptors, and farnesoid X receptor (1). Since RXRs heterodimerize with multiple nuclear hormone receptors, they play a central role in transcriptional control of numerous hormonal signaling pathways by binding to cis-acting response elements in the promoter/enhancer region of target genes (2).

Background: Ectonucleotide pyrophosphatase-phosphodiesterase 1 (ENPP1) is a single-pass, type II transmembrane protein primarily involved in ATP hydrolysis at the plasma membrane. Targeting of ENPP1 to the basolateral cell surface relies on the presence of a carboxy-terminal di-leucine-based signal (1). ENPP1 plays important roles in bone mineralization and soft tissue calcification (2-5). Mutations in the corresponding ENPP1 gene cause generalized arterial calcification in infancy (GACI) and idiopathic infantile arterial calcification (IIAC) (6,7). ENPP1 inhibits insulin receptor function and overexpression of this enzyme causes insulin resistance and glucose intolerance in mice (8,9). Genetic variants of ENPP1 have been associated with obesity and type 2 diabetes (10-12).

Background: NADK, also known as NAD kinase, is a cytoplasmic protein responsible for maintaining the pool of available NADP+ and NADPH within the cell (1). Using ATP as a phosphate donor, NADK catalyzes the phosphorylation of NAD+ to NADP+. This molecule is then reduced to NADPH and utilized in various metabolic and biosynthetic pathways (2). NADK has been suggested to play a role in glucose metabolism due to the effect NADPH production has on both the insulin secretion and survival of pancreatic β-cells (3). NADPH has a vital role in protecting cells from oxidative stress through its neutralizing effect on reactive oxygen species (ROS), which also accumulate during cell growth (2, 3, 4). Along with the p53 tumor suppression protein, NADK has been a suggested target in cancer therapy due its link to NADPH production and its resulting protective role on growing and proliferating cells (2).

Background: The aldehyde dehydrogenase family is a large group of enzymes that catalyze the oxidization of aldehydes into carboxylic acids (1). Aldehyde Dehydrogenase 1A2 (ALDH1A2, RALHD2) is among a group of aldehyde dehydrogenases that catalyze the metabolism of retinaldehyde into retinoic acid (RA), which plays a critically important signaling role in animal development (2). Research studies have shown that ALDH1A2 also plays a role postnatally in modulating the effects of RA signaling on immune cell function (3-5). In one example using a genetic mouse model, it was shown that ALDH1A2-dependent RA signaling was a downstream mediator of NOTCH-dependent T cell differentiation (6).

Background: Peroxisome proliferator-activated receptor γ (PPARγ) is a member of the ligand-activated nuclear receptor superfamily and functions as a transcriptional activator (1). PPARγ is preferentially expressed in adipocytes as well as in vascular smooth muscle cells and macrophage (2). Besides its role in mediating adipogenesis and lipid metabolism (2), PPARγ also modulates insulin sensitivity, cell proliferation and inflammation (3). PPARγ transcriptional activity is inhibited by MAP kinase phosphorylation of PPARγ at Ser84 (4,5).

Background: Methylation of DNA at cytosine residues in mammalian cells is a heritable, epigenetic modification that is critical for proper regulation of gene expression, genomic imprinting and development (1,2). Three families of mammalian DNA methyltransferases have been identified: DNMT1, DNMT2 and DNMT3 (1,2). DNMT1 is constitutively expressed in proliferating cells and functions as a maintenance methyltransferase, transferring proper methylation patterns to newly synthesized DNA during replication. DNMT3A and DNMT3B are strongly expressed in embryonic stem cells with reduced expression in adult somatic tissues. DNMT3A and DNMT3B function as de novo methyltransferases that methylate previously unmethylated regions of DNA. DNMT2 is expressed at low levels in adult somatic tissues and its inactivation affects neither de novo nor maintenance DNA methylation. DNMT1, DNMT3A and DNMT3B together form a protein complex that interacts with histone deacetylases (HDAC1, HDAC2, Sin3A), transcriptional repressor proteins (RB, TAZ-1) and heterochromatin proteins (HP1, SUV39H1), to maintain proper levels of DNA methylation and facilitate gene silencing (3-8). Improper DNA methylation contributes to diseased states such as cancer (1,2). Hypermethylation of promoter CpG islands within tumor suppressor genes correlates with gene silencing and the development of cancer. In addition, hypomethylation of bulk genomic DNA correlates with and may contribute to the onset of cancer. DNMT1, DNMT3A and DNMT3B are over-expressed in many cancers, including acute and chronic myelogenous leukemias, in addition to colon, breast and stomach carcinomas (9-12).

Background: Monocyte chemotactic protein-1 (MCP-1), also known as CCL2, monocyte chemotactic activating factor (MCAF) or glioma-derived chemotactic factor-2 (GDCF-2), is the product of the human JE gene and a member of the family of C-C (or β) chemokines (1-4). The predicted molecular weight of MCP-1 protein is 11-13 kDa, but it may migrate at 20-30 kDa due to glycosylation. MCP-1 is secreted by a variety of cell types in response to pro-inflammatory stimuli and was originally described for its chemotactic activity on monocytes. This activity has led to studies demonstrating its role in diseases characterized by monocyte infiltrates such as psoriasis (5), rheumatoid arthritis (6) and atherosclerosis (7). MCP-1 may also contribute to tumor progression and angiogenesis (8). Signaling by MCP-1 is mediated by the G-protein coupled receptor CCR2 (9).
