Background: The methylation state of lysine residues in histone proteins is a major determinant of the formation of active and inactive regions of the genome and is crucial for proper programming of the genome during development (1,2). Jumonji C (JmjC) domain-containing proteins represent the largest class of potential histone demethylase proteins (3). The JmjC domain can catalyze the demethylation of mono-, di-, and tri-methyl lysine residues via an oxidative reaction that requires iron and α-ketoglutarate (3). Based on homology, both humans and mice contain at least 30 such proteins, which can be divided into 7 separate families (3). The jumonji domain-containing protein 2 (JMJD2) family, also known as the JmjC domain-containing histone demethylation protein 3 (JHDM3) family, contains four members: JMJD2A/JHDM3A, JMJD2B/JHDM3B, JMJD2C/JHDM3C, and JMJD2D/JHDM3D. In addition to the JmjC domain, these proteins also contain JmjN, PHD, and tudor domains, the latter of which has been shown to bind to methylated histone H3 at Lys4 and Lys9, and methylated histone H4 at Lys20 (4,5). JMJD2 proteins have been shown to demethylate di- and tri-methyl histone H3 at Lys9 and Lys36 and function as both activators and repressors of transcription (6-11). JMJD2A, JMJD2C, and JMJD2D function as coactivators of the androgen receptor in prostate tumor cells (7). In contrast, JMJD2A also associates with Rb and NCoR corepressor complexes and is necessary for transcriptional repression of target genes (8,9). JMJD2B antagonizes histone H3 Lys9 tri-methylation at pericentric heterochromatin (10). JMJD2C, also known as GASC1, is amplified in squamous cell carcinomas and metastatic lung carcinoma and inhibition of JMJD2C expression decreases cell proliferation (11,12). JMJD2C has also been identified as a downstream target of Oct-4 and is critical for the regulation of self-renewal in embryonic stem cells (13).

Background: Jumonji domain-containing protein 6 (JMJD6) is a bifunctional metalloenzyme belonging to the large family of JmjC domain-containing proteins. These proteins are ferrous iron- and 2-oxoglutarate-dependent enzymes (Fe2+/2OG) that catalyze hydroxylation and demethylation reactions on a wide variety of protein and nucleic acid substrates (1). JMJD6 is thought to act as both a lysyl-hydroxylase and an arginine demethylase, although the latter activity remains controversial. Specifically, JMJD6 has been shown to catalyze 5-hydroxylation of Lys15 and Lys276 residues on the protein U2AF2 / U2AF65 in vivo, affecting pre-mRNA splicing activity (2). It has also been reported that JMJD6 hydroxylates the Lys382 residue of p53, preventing acetylation and promoting association of p53 with MDMX, resulting in inhibition of p53 transcriptional activity (3). In addition to hydroxylase activity, JMJD6 also acts as an arginine demethylase by targeting histone H3 at Arg2 (H3R2me) and histone H4 at Arg3 (H4R3me). Unlike other members of the JmjC family, JMJD6 appears to have no lysine demethylase activity (4). Studies have shown that JMJD6 colocalizes with BRD4 at a subset of enhancers to demethylate H3R2me2 repressor marks (5). It has also been reported to demethylate non-histone substrates, such as estrogen receptor (ERα) (6), heat shock protein 70 (HSP70) (7), RNA helicase A (8), and the TRAF6 E3 ubiquitin ligase following activation of toll-like receptors (9).Although mutations in the sequence of JMJD6 have not been observed in cancer, its overexpression is identified in various cancers and is associated with aggressive disease progression and poor prognosis (10). This holds true for certain types of colon (3), lung (11), and breast cancers (12, 13). Based on these findings, JMJD6 has drawn interest as a potential therapeutic target and biomarker for certain cancer types.

Background: The stress-activated protein kinase/Jun-amino-terminal kinase SAPK/JNK is potently and preferentially activated by a variety of environmental stresses including UV and gamma radiation, ceramides, inflammatory cytokines, and in some instances, growth factors and GPCR agonists (1-6). As with the other MAPKs, the core signaling unit is composed of a MAPKKK, typically MEKK1-MEKK4, or by one of the mixed lineage kinases (MLKs), which phosphorylate and activate MKK4/7. Upon activation, MKKs phosphorylate and activate the SAPK/JNK kinase (2). Stress signals are delivered to this cascade by small GTPases of the Rho family (Rac, Rho, cdc42) (3). Both Rac1 and cdc42 mediate the stimulation of MEKKs and MLKs (3). Alternatively, MKK4/7 can be activated in a GTPase-independent mechanism via stimulation of a germinal center kinase (GCK) family member (4). There are three SAPK/JNK genes each of which undergoes alternative splicing, resulting in numerous isoforms (3). SAPK/JNK, when active as a dimer, can translocate to the nucleus and regulate transcription through its effects on c-Jun, ATF-2, and other transcription factors (3,5).

Background: JunB is a basic region, leucine zipper (bZIP) transcription factor belonging to the Jun family that includes c-Jun and JunD. Jun family members homodimerize or heterodimerize with Fos and ATF proteins to form a functional transcription factor AP-1 (activator protein 1), whose activity is regulated by a variety of physiological and pathological stimuli such as growth factors, infections, and stress signals (1-4). While JunB sometimes antagonizes c-Jun transcriptional activity, it may functionally substitute for c-Jun during development in mice (5-7). JunB regulates hematopoietic stem cell number and plays an important role in the pathogenesis of chronic myelogenous leukemia (CML) and acute myeloid leukemia (AML) (8,9).

Background: JunD, along with closely related family members c-Jun and JunB, is a transcription factor that can activate or repress a wide array of target genes (1,2). JunD transcriptional activity is modulated by phosphorylation in response to cellular stress via the c-Jun N-terminal Kinase (JNK)/Stress-Activated Protein Kinase (SAPK) family of protein kinases (3,4). JunD activity can also be modulated by the MAPK pathway in response to growth factors. Its transcriptional capacity is further regulated by other binding partners that affect JunD expression levels and DNA binding capacity (reviewed in 5). All Jun proteins are capable of forming dimers with Fos-, ATF- and CREB-family transcription factors to form the AP-1 complex that differentially regulates a variety of target genes involved in cellular growth, proliferation, differentiation, and apoptosis (reviewed in 5 and 6). Unlike JunB and c-Jun, which share a high degree of homology (>95%), JunD is less conserved (~75%) at the amino acid level (1). Growing evidence suggests that JunD protein expression is regulated independently of other family members (reviewed in 5). It is thought that JunD may have functional significance beyond the typical Jun-family milieu. This is exemplified by the fact that JunD knockout mice are viable, bearing specific defects in cardiomyocyte function and bone growth, whereas their c-Jun counterparts develop significant, multi-organ defects during embryogenesis and die at E12.5 (7-10). JunD appears to specifically regulate genes involved in antioxidant response and hydrogen peroxide production and plays an important role in angiogenesis via its ability to exert transcriptional control over the VEGF gene (11). Furthermore, JunD appears to play an important roll in metabolism via modulation of IGF-I signaling pathways (12). Recent studies have shown that JunD regulates GADD45 α and γ expression in prostate cancer cells and that inhibition of JunD promotes apoptosis. Thus, JunD may be a viable therapeutic target for the treatment of prostate cancer (13).

Background: Ubiquitin is a conserved polypeptide unit that plays an important role in the ubiquitin-proteasome pathway. Ubiquitin can be covalently linked to many cellular proteins by the ubiquitination process, which targets proteins for degradation by the 26S proteasome. Three components are involved in the target protein-ubiquitin conjugation process. Ubiquitin is first activated by forming a thiolester complex with the activation component E1; the activated ubiquitin is subsequently transferred to the ubiquitin-carrier protein E2, then from E2 to ubiquitin ligase E3 for final delivery to the epsilon-NH2 of the target protein lysine residue (1-3). The ubiquitin-proteasome pathway has been implicated in a wide range of normal biological processes and in disease-related abnormalities. Several proteins such as IκB, p53, cdc25A, and Bcl-2 have been shown to be targets for the ubiquitin-proteasome process as part of regulation of cell cycle progression, differentiation, cell stress response, and apoptosis (4-7).

Background: The potassium/chloride cotransporter 2 (KCC2, SLC12A5) is a neuron-specific transport protein responsible for regulating the cotransport of potassium and chloride ions. KCC2 uses the energy of the electrochemical potassium gradient to export chloride ions from cells, therefore maintaining intracellular chloride ion concentrations in mature neurons (1,2). The intracellular concentration of chloride ions determines the neuronal response to the inhibitory neurotransmitter GABA and glycine. As a result, KCC2 can play a critical role in regulating neuronal excitability in mature central nervous system neurons (3-5). Altered KCC2 expression and reduced KCC2 activity can result in an increase in intracellular chloride ion concentrations and subsequent hyperexcitability of neuronal systems. Cases of aberrant KCC2 function are associated with neurological disorders, such as multiple forms of epilepsy, neuropathic pain, and schizophrenia (6-10).

Background: Potassium channel tetramerization domain-containing protein 12 (KCTD12) belongs to the family of KCTD proteins, which also contains KCTD8, 12b, and 16. These proteins are auxiliary subunits of GABAB receptors (1). The principal subunit of the GABAB receptor is formed by two GABAB receptors, which bind to GABAB ligands, couple to G proteins to inhibit adenylate cyclase production, and gate ion channels (e.g., the GIRK channels) (2). The auxiliary subunits contribute to receptor desensitization. KCTD12 produces fast desensitization by uncoupling the βγ subunits of the G protein from their effector channels (3). Research studies indicate that KCTD12 represents a biomarker with diagnostic and prognostic potential for gastrointestinal stromal tumors (4).

Background: The nuclear factor-like 2 (NRF2) transcriptional activator binds antioxidant response elements (ARE) of target gene promoter regions to regulate expression of oxidative stress response genes. Under basal conditions, the NRF2 inhibitor INrf2 (also called KEAP1) binds and retains NRF2 in the cytoplasm where it can be targeted for ubiquitin-mediated degradation (1). Small amounts of constitutive nuclear NRF2 maintain cellular homeostasis through regulation of basal expression of antioxidant response genes. Following oxidative or electrophilic stress, KEAP1 releases NRF2, thereby allowing the activator to translocate to the nucleus and bind to ARE-containing genes (2). The coordinated action of NRF2 and other transcription factors mediates the response to oxidative stress (3). Altered expression of NRF2 is associated with chronic obstructive pulmonary disease (COPD) (4). NRF2 activity in lung cancer cell lines directly correlates with cell proliferation rates, and inhibition of NRF2 expression by siRNA enhances anti-cancer drug-induced apoptosis (5).
