Epigenetic modifications and dynamic changes in chromatin organization by organizer proteins have recently been shown to play an instrumental role in regulating cancer-promoting genes. Special AT-rich binding protein (SATB1) is a unique type of global regulator that integrates higher-order chromatin organization -withregulation of gene expression. SATB1 is a T cell-enriched transcription factor and a chromatin organizer essential for controlling genes that participate in T-cell development and activation. It regulates gene expression by periodically anchoring matrix attachment regions to the nuclear matrix and directly recruiting chromatin-modifying factors. Depending on its posttranslational modifications, SATB1 activates or represses multiple genes.Its expression is regulated by interleukin-4 (IL4) during T helper-2(Th2) cell differentiation.

LONP1(Lon protease homolog, mitochondrial) is also named as LONP, LONHS, HLON, LON, PRSS15, PIM1, MGC1498 and belongs to the peptidase S16 family. It seems to play a major role in the elimination of oxidatively modified proteins in the mitochondrial matrix. LONP1, also a nuclearly encoded and mitochondrially located stress-responsive protease, is involved in heme-mediated ALAS-1 turnover. It recognizes specific surface determinants or folds, initiates proteolysis at solvent-accessible sites, and generates unfolded polypeptides that are then processively degraded.

CD44 was designed, produced, and validated as part of the Joy Cappel Young Investigator Award (JCYIA). CD44 is a receptor for hyaluronic acid (HA), an integral component of the extracellular matrix. CD44 mediates cell-cell and cell-matrix interactions through its affinity for HA, and can also interact with ligands such as osteopontin, collagens, and matrix metalloproteinases (MMPs). The multiple protein isoforms are encoded by a single gene by alternative splicing and are further modified by a range of post-translational modifications. CD44 function is controlled by these posttranslational modifications. The major physiological role of CD44 is to maintain organ and tissue structure via cell-cell and cell-matrix adhesion, but certain variant isoforms can also mediate lymphocyte activation and homing, and the presentation of chemical factors and hormones. CD44 participates in a wide variety of cellular functions including lymphocyte activation, recirculation and homing, hematopoiesis, and tumor metastasis. CD44 is a multi-structural and multi-functional cell surface molecule involved in cell proliferation, cell differentiation, cell migration, angiogenesis, presentation of cytokines, chemokines, and growth factors to the corresponding receptors, and docking of proteases at the cell membrane, as well as in signaling for cell survival. All these biological properties are essential to the physiological activities of normal cells, but they are also associated with the pathologic activities of cancer cells. CD44, particularly its variants, may be useful as a diagnostic or prognostic marker of malignancy and, in at least some human cancers, it may be a potential target for cancer therapy.

CTSK(cathepsin K), also named as CTSO, CTSO2, is a recently identified lysosomal cysteine proteinase. CTSK is synthesized as a proenzyme of 38 kDa and subsequently enters acidic lysosomal compartments, in which the propeptide is cleaved and transformed into an active enzyme and it may influence adipocyte differentiation through modifying extracellular matrix components. It is revealed both the 46-kDa cathepsin-K precursor and the 30-kDa mature form in mouse bone extracts. The high CTSK protein levels are only detected in primary cultured fibroblasts derived from normal and neoplastic breast tissue, where the 37- and 25-kDa bands to be detected correspond to pro- and mature proteins through western blot. The full length protein has a signal peptides with 15 amino acids and a propeptide with 99 amino acids. CTSK may have cross reaction with the other members of cathepsin family and form a complex of 70 kDa with an unidentified subunit.

Chromatin, the physiological packaging structure of histone proteins and DNA, is considered a key element in regulating gene expression. Several complexes involved in transcriptional regulation function by either modifying histones or altering chromatin structure. Postranslational modifications of histones, such as acetylation, phosphorylation and methylation, contribute to the regulation of transcription. The ATP-dependent chromatin-remodeling complexes alter chromatin structure by using the energy of ATP hydrolysis to locally disrupt the association of histones with DNA, displacing the nucleosomes from promoter and enhancer regions, and therefore allowing transcription initiation. Chromatin remodeling complexes have been purified from a variety of organisms, and most cell types contain more than one type of complex. These complexes contain structurally related catalytic subunits, but differ in the way in which they manipulate chromatin. Three families of complexes have been described the SWI/SNF family, ISWI family, and Mi-2 family. The SWI/SNF family of ATP-dependent remodeling complexes was identified in yeast, drosophila, and human. It causes nucleosomes to change structure and/or position in order to allow transcriptional activators to gain access to their target sites. The SWI/SNF complex was originally identified in yeast as a 2 MDa complex, later shown to be highly conserved in all eukaryotes. Components of the hSWI/SNF complexes have been implicated in a range of cellular events including gene activation, regulation of cell growth, and development. The human homologue of yeast SNF5, SMARCB1, was identified in a two-hybrid screening performed to identify binding targets of the integrase of HIV, and the gene called INI1. Many studies have indicated that yeast SNF and its human counterparts are able to interact with sequence-specific transcription factors, which may recruit the complex to specific genes. For example, it has been shown that SMARCB1 interacts with the protooncogene c-Myc and the SWI complex is necessary for c-Myc mediated transactivation. Mutations in SNF5 and Brg1, both SWI components, suggest a connection of the complex with cancer. In fact, SMARCB1 displays properties of a tumor-suppressor gene, as sporadic rhabdoid tumors show biallelic loss-of-function mutations, and germline mutations confer and autosomal-dominant syndrome that predisposes patients to a variety of rhabdoid cancers.
