Background: The polycomb group (PcG) proteins are involved in maintaining the silenced state of multiple developmentally regulated genes and contribute to the maintenance of cell identity, cell cycle regulation, and oncogenesis. Enhancer of zest homolog 1 (Ezh1), is a member of this large protein family and a subunit of the polycomb repressor complex 2 (PRC2), also containing SUZ12 and EED. Ezh1 and its paralog Ezh2 are mutually exclusive catalytic subunits of the PRC2 complex, which functions to mono-, di-, and tri-methylated Lys27 on histone H3, a mark that is associated with transcriptional repression. While EZH1 is less abundant than EZH2, it is still required for cell identity and self-renewal of embryonic stem cells (1,2). Ezh1 is also required for hematopoietic stem cell maintenance and functions to prevent a senescence-like cell cycle arrest (3). Ezh1 is required for myogenic differentiation and hepatocyte homeostasis and regeneration (4,5). While many studies have implicated Ezh2 in multiple types of cancer, a potential role for Ezh1 is less understood. However, several studies have shown dual inhibitors of Ezh1/Ezh2 to be more effective than Ezh2-specific inhibitors in treatment of multiple myeloma, prostate cancer, diffuse large B-cell lymphoma, and leukemia, suggesting an important role for Ezh1 in cancer (6-8).

Background: The polycomb group (PcG) proteins are involved in maintaining the silenced state of several developmentally regulated genes and contribute to the maintenance of cell identity, cell cycle regulation, and oncogenesis (1,2). Enhancer of zeste homolog 2 (Ezh2), a member of this large protein family, contains four conserved regions including domain I, domain II, and a cysteine-rich amino acid stretch that precedes the carboxy-terminal SET domain (3). The SET domain has been linked with histone methyltransferase (HMTase) activity. Moreover, mammalian Ezh2 is a member of a histone deacetylase complex that functions in gene silencing, acting at the level of chromatin structure (4). Ezh2 complexes methylate histone H3 at Lys9 and 27 in vitro, which is thought to be involved in targeting transcriptional regulators to specific loci (5). Ezh2 is deregulated in various tumor types, and its role, both as a primary effector and as a mediator of tumorigenesis, has become a subject of increased interest (6).

Background: F3/contactin (CNTN, contactin 1) is a glycosylphosphatidylinositol (GPI)-anchored neural cell adhesion protein belonging to the immunglobulin protein superfamily (1). During early mammalian development, F3/contactin is expressed in granule neuronal progenitor (GNP) cells, where it was shown to promote GNP differentiation, in part by antagonizing sonic hedgehog (SHH)-mediated proliferation (2). Biochemical studies have shown that F3/contactin interacts with the phosphatase PTPRZ on the surface of oligodendrocyte precursor cells, an association that was shown to be essential for oligodendrocyte maturation (3). F3/contactin expression is also abundant in post-mitotic neurons, where its functions as a neural cell adhesion protein have been suggested to play an important role in synaptic plasticity and memory (4). Although primarily associated with neuronal development and function, F3/contactin expression has also been implicated in extra-neuronal tumorigenesis. For example, expression of F3/contactin was detected in both primary prostate tumors, and lymph node and bone metastases, while patient tumor samples with detectable F3/contactin expression were associated with tumor progression and reduced recurrance-free survival (5).

Background: Endogenous cannabinoids have been implicated in addictive behaviors and drug abuse (1). Fatty-acid amide hydrolase 1 (FAAH1) is a plasma membrane-bound hydrolase that converts oleamide to oleic acid (2). This hydrolase also converts the cannabinoid anandamide, the endogenous ligand for the CB1 cannabinoid receptor, to arachidonic acid, suggesting a role in fatty-acid amide inactivation (2). Mice lacking FAAH1 have significantly higher levels of anandamide in the brain and show decreased sensitivity to pain, further indicating a role for FAAH1 in the regulation of endocannabinoid signaling in vivo (3). FAAH1 null mice also demonstrate an increased preference for alcohol and an increased voluntary uptake of alcohol as compared to wild-type mice, indicating a role of FAAH1 in modulating addictive behaviors (1).

Background: Fatty acid binding proteins (FABPs) bind to fatty acids and other lipids to function as cytoplasmic lipid chaperones (1,2). They participate in the transport of fatty acids and other lipids to various cellular pathways (2).

Background: Fatty acid binding proteins (FABPs) are cytoplasmic lipid chaperones that bind fatty acids and lipids for transport to various cellular components (1,2). Research studies demonstrate differential FABP expression in several types of tumors and their normal-cell counterparts (3). Fatty acid binding protein 3 (FABP3) is predominantly expressed in heart, skeletal muscle, brain, and mammary gland (4). FABP3 may play a role in supplying energy to the heart and other tissues (5). The release of FABP3 from the heart upon infarction is used as a serum marker for myocardial stress and cardiotoxicity (6). Additional studies suggest that FABP3 is a potential tumor suppressor in breast cancer (7).

Background: Fatty acid binding proteins (FABPs) bind to fatty acids and other lipids to function as cytoplasmic lipid chaperones (1). They participate in the transport of fatty acids and other lipids to various cellular pathways (2). The predominant fatty acid binding protein found in adipocytes is FABP4, also called adipocyte fatty acid binding protein or aP2. FABP4 is also expressed in macrophages (3). FABP4 knockout mice fed a high-fat and high-calorie diet become obese but develop neither insulin resistance nor diabetes, suggesting that this protein might be a link between obesity and insulin resistance and diabetes (4). Mice deficient in both FABP4 and ApoE show protection against atherosclerosis when compared with mice deficient only in ApoE (3). Mice carrying a FABP4 genetic variant exhibit both reduced FABP4 expression and a reduced potential for developing type 2 diabetes and coronary heart disease. A related study in humans indicated a similar pattern, suggesting that FABP4 may be a potential therapeutic target in the treatment of these disorders (1).

Background: Fatty acid binding proteins (FABPs) bind to fatty acids and other lipids to function as cytoplasmic lipid chaperones (1). They participate in the transport of fatty acids and other lipids to various cellular pathways (1). They are critical mediators of metabolic processes, and are increasingly being understood to play key roles in disease (2). FABP5 is known as the epidermal fatty acid binding protein as it was originally identified in studies on psoriasis (3) where it was shown to play a role a role in keratinocyte differentiation (4). It has since been found to play diverse roles in other normal physiological processes as well as in disease states (5).

They participate in the transport of fatty acids and other lipids to various cellular pathways (2). Differential expression of FABPs is found in several types of tumors and their normal-cell counterparts (3). FABP7 is abundantly expressed in fetal brain and may be essential for development (4). Expression is required for the establishment of the radial glial fiber system, a system that is necessary for the development of cortical layers (5). Increased expression of FABP7 is associated with reduced survival in patients with glioblastoma (6), and is also found in glial cells following nerve injury (7). Investigators have found loss of FABP7 may be involved in the development and progression of breast cancer and expression of FABP7 has been shown to induce mammary differentiation and to inhibit growth of breast cancer cells (8,9).

Background: Focal adhesion kinase (FAK) is a widely expressed cytoplasmic protein tyrosine kinase involved in integrin-mediated signal transduction. It plays an important role in the control of several biological processes, including cell spreading, migration, and survival (1). Activation of FAK by integrin clustering leads to autophosphorylation at Tyr397, which is a binding site for the Src family kinases PI3K and PLCγ (2-5). Recruitment of Src family kinases results in the phosphorylation of Tyr407, Tyr576, and Tyr577 in the catalytic domain, and Tyr871 and Tyr925 in the carboxy-terminal region of FAK (6,7).

Background: FAM3C, also known as ILEI (interleukin-like epithelial-to-mesenchymal transition [EMT] inducer), is a cytokine-like protein and member of the FAM3 family. FAM3C plays an important role in EMT and metastasis during cancer progression in human and mouse cells, and is highly expressed in human cancer (1,2). In colorectal cancer, researchers have indicated that FAM3C is a marker for EMT and tumor progression, and that high expression of FAM3C is predictive of poor prognosis (3). While EMT induction by FAM3C can be independent of TGF-beta, research studies have also shown TGF-beta-dependent regulation of FAM3C expression at the translational level in mouse and human cells (4,5).FAM3C has also been linked to regulation of osteoblast differentiation (6), and to accumulation of amyloid beta plaques in Alzheimer’s disease (7). FAM3C exists in monomeric and in homodimeric form, and research shows that FAM3C homodimers contain its EMT-inducing and tumor promoting activity (8).
