Abstract
DNA and RNA binding proteins (DRBPs) are a broad class of molecules that regulate numerous cellular processes across all living organisms, creating intricate dynamic multilevel networks to control nucleotide metabolism and gene expression. These interactions are highly regulated, and dysregulation contributes to the development of a variety of diseases, including cancer. An increasing number of proteins with DNA and/or RNA binding activities have been identified in recent years, and it is important to understand how their activities are related to the molecular mechanisms of cancer. In addition, many of these proteins have overlapping functions, and it is therefore essential to analyze not only the loss of function of individual factors, but also to group abnormalities into specific types of activities in regard to particular cancer types. In this review, we summarize the classes of DNA-binding, RNA-binding, and DRBPs, drawing particular attention to the similarities and differences between these protein classes. We also perform a cross-search analysis of relevant protein databases, together with our own pipeline, to identify DRBPs involved in cancer. We discuss the most common DRBPs and how they are related to specific cancers, reviewing their biochemical, molecular biological, and cellular properties to highlight their functions and potential as targets for treatment.

Abstract
Pre-mRNA splicing is a fundamental process in mammalian gene expression, and alternative splicing plays an extensive role in generating protein diversity. Because the majority of genes undergo pre-mRNA splicing, most cellular processes depend on proper spliceosome function. We focus on the cell cycle and describe its dependence on pre-mRNA splicing and accurate alternative splicing. We outline the key cell-cycle factors and their known alternative splicing isoforms. We discuss different levels of pre-mRNA splicing regulation such as post-translational modifications and changes in the expression of splicing factors. We describe the effect of chromatin dynamics on pre-mRNA splicing during the cell cycle. In addition, we focus on spliceosome component SF3B1, which is mutated in many types of cancer, and describe the link between SF3B1 and its inhibitors and the cell cycle.

Abstract
BACKGROUND The molecular pathogenesis of infection by hepatitis B virus with human is extremely complex and heterogeneous. To date the molecular information is not clearly defined despite intensive research efforts. Thus, studies aimed at transcription and regulation during virus infection or combined researches of those already known to be beneficial are needed. AIMS With the purpose of identifying the transcriptional regulators related to infection of hepatitis B virus in gene level, the gene expression profiles from some normal individuals and hepatitis B patients were analyzed in our study. METHODS In this work, the differential expressed genes were selected primarily. The several genes among those were validated in an independent set by qRT-PCR. Then the differentially co-expression analysis was conducted to identify differentially co-expressed links and differential co-expressed genes. Next, the analysis of the regulatory impact factors was performed through mapping the links and regulatory data. In order to give a further insight to these regulators, the co-expression gene modules were identified using a threshold-based hierarchical clustering method. Incidentally, the construction of the regulatory network was generated using the computer software. RESULTS A total of 137,284 differentially co-expressed links and 780 differential co-expressed genes were identified. These co-expressed genes were significantly enriched inflammatory response. The results of regulatory impact factors revealed several crucial regulators related to hepatocellular carcinoma and other high-rank regulators. Meanwhile, more than one hundred co-expression gene modules were identified using clustering method. CONCLUSIONS In our study, some important transcriptional regulators were identified using a computational method, which may enhance the understanding of disease mechanisms and lead to an improved treatment of hepatitis B. However, further experimental studies are required to confirm these findings.

Abstract
![]()
The
spliceosome is a dynamic macromolecular machine composed of
five small nuclear ribonucleoparticles (snRNPs), the NineTeen Complex
(NTC), and other proteins that catalyze the removal of introns mature
to form the mature message. The NTC, named after its founding member Saccharomyces cerevisiae Prp19, is a conserved spliceosome
subcomplex composed of at least nine proteins. During spliceosome
assembly, the transition to an active spliceosome correlates with
stable binding of the NTC, although the mechanism of NTC function
is not understood. Schizosaccharomyces pombe Cdc5, a core subunit of the NTC, is an essential protein required
for pre-mRNA splicing. The highly conserved Cdc5 N-terminus contains
two canonical Myb (myeloblastosis) repeats (R1 and R2) and a third
domain (D3) that was previously classified as a Myb-like repeat. Although
the N-terminus of Cdc5 is required for its function, how R1, R2, and
D3 each contribute to functionality is unclear. Using a combination
of yeast genetics, structural approaches, and RNA binding assays,
we show that R1, R2, and D3 are all required for the function of Cdc5
in cells. We also show that the N-terminus of Cdc5 binds RNA in vitro. Structural and functional analyses of Cdc5-D3
show that, while this domain does not adopt a Myb fold, Cdc5-D3 preferentially
binds double-stranded RNA. Our data suggest that the Cdc5 N-terminus
interacts with RNA structures proposed to be near the catalytic core
of the spliceosome.

Abstract
Nuclear proteins typically contain short stretches of basic amino acids (nuclear localization sequences; NLSs) that bind karyopherin α family members, directing nuclear import. Here, we identify CTNNBL1 (catenin-β-like 1), an armadillo motif-containing nuclear protein that exhibits no detectable primary sequence homology to karyopherin α, as a novel, selective NLS-binding protein. CTNNBL1 (a single-copy gene conserved from fission yeast to man) was previously found associated with Prp19-containing RNA-splicing complexes as well as with the antibody-diversifying enzyme AID. We find that CTNNBL1 association with the Prp19 complex is mediated by recognition of the NLS of the CDC5L component of the complex and show that CTNNBL1 also interacts with Prp31 (another U4/U6.U5 tri-snRNP-associated splicing factor) through its NLS. As with karyopherin αs, CTNNBL1 binds NLSs via its armadillo (ARM) domain, but displays a separate, more selective NLS binding specificity. Furthermore, the CTNNBL1/AID interaction depends on amino acids forming the AID conformational NLS with CTNNBL1-deficient cells showing a partial defect in AID nuclear accumulation. However, in further contrast to karyopherin αs, the CTNNBL1 N-terminal region itself binds karyopherin αs (rather than karyopherin β), suggesting a function divergent from canonical nuclear transport. Thus, CTNNBL1 is a novel NLS-binding protein, distinct from karyopherin αs, with the results suggesting a possible role in the selective intranuclear targeting or interactions of some splicing-associated complexes.

Abstract
CDC5 proteins are components of the pre-mRNA splicing complex and essential for cell cycle progression in yeast, plants and mammals. Human CDC5 is phosphorylated in a mitogen-dependent manner, and its association with the spliceosome is ATP-dependent. Examination of the amino acid sequence suggests that CDC5L may be phosphorylated at up to 28 potential consensus recognition sequences for known kinases, however, the identity of actual phosphorylation sites, their role in regulating CDC5L activity, and the kinases responsible for their phosphorylation have not previously been determined. Using two-dimensional phosphopeptide mapping and nanoelectrospray mass spectrometry, we now show that CDC5L is phosphorylated on at least nine sites in vivo. We demonstrate that while CDC5L is capable of forming homodimers in vitro and in vivo, neither homodimerization nor nuclear localization is dependent on phosphorylation at these sites. Using an in vitro splicing assay, we show that phosphorylation of CDC5L at threonines 411 and 438 within recognition sequences for CDKs are required for CDC5L-mediated pre-mRNA splicing. We also demonstrate that a specific inhibitor of CDK2, CVT-313, inhibits CDC5L phosphorylation in both in vitro kinase assays and in vivo radiolabeling experiments in cycling cells. These studies represent the first demonstration of a regulatory role for phosphorylation of CDC5L, and suggest that targeting these sites or the implicated kinases may provide novel strategies for treating disorders of unguarded cellular proliferation, such as cancer.

Abstract
As a cell cycle regulator, the Myb-related CDC5 protein was reported to be essential for the G2 phase of the cell cycle in yeast and animals, but little is known about its function in plants. Here we report the functional characterization of the CDC5 gene in Arabidopsis thaliana. Arabidopsis CDC5 (AtCDC5) is mainly expressed in tissues with high cell division activity, and is expressed throughout the entire process of embryo formation. The AtCDC5 loss-of-function mutant is embryonic lethal. In order to investigate the function of AtCDC5 in vivo, we generated AtCDC5-RNAi plants in which the expression of AtCDC5 was reduced by RNA interference. We found that the G2 to M (G2/M) phase transition was affected in the AtCDC5-RNAi plants, and that endoreduplication was increased. Additionally, the maintenance of shoot apical meristem (SAM) function was disturbed in the AtCDC5-RNAi plants, in which both the WUSCHEL (WUS)-CLAVATA (CLV) and the SHOOT MERISTEMLESS (STM) pathways were impaired. In situ hybridization analysis showed that the expression of STM was greatly reduced in the shoot apical cells of the AtCDC5-RNAi plants. Moreover, cyclinB1 or Histone4 was found to be expressed in some of these cells when the transcript of STM was undetectable. These results suggest that AtCDC5 is essential for the G2/M phase transition and may regulate the function of SAM by controlling the expression of STM and WUS.

Abstract
Heart failure results from the cumulative death of cardiomyocytes, and the inability of remaining cells to regenerate. Efforts toward transcriptional reprogramming of cardiomyocytes by overexpressing E1A or E2F1 have been limited by the inability of cardiomyocytes to enter and complete mitosis. Human CDC5 (hCDC5), a component of the pre-mRNA splicing complex, has been shown to regulate G2/M transit in asynchronously dividing cells. We now show that co-infection of recombinant adenoviruses expressing E1A/E1B and hCDC5 promotes cell cycle re-entry and G2/M progression in post-mitotic cardiomyocytes. Co-expression of E1A/E1B and hCDC5 induced nuclear localization of cyclin-dependent kinase 1 and cyclin B1, and was sufficient to promote mitotic entry as determined by an increase in mitotic index only in co-infected cells. E1A/E1B and hCDC5 promoted cell division, as evidenced by an increase in the number of cardiomyocytes following co-infection. Thus, overexpression of E1A/E1B and hCDC5 resulted in cell cycle re-entry, DNA synthesis, cell division, and an increase in cardiomyocyte number, suggesting the formation of new cardiomyocytes. These studies suggest that G1/S-phase transcriptional regulators, in combination with pre-mRNA splicing factors, such as CDC5, that regulate rate-limiting G2/M target genes may prove useful in developing therapies to stimulate myocardial regeneration.

Abstract
Extracellular signaling pathways regulating myoblast differentiation and cell-cycle withdrawal are not completely understood. Stem cell antigen-1 (Sca-1/Ly-6A/E) is a glycosylphosphatidylinositol-anchored membrane protein known for its role in T-cell activation, and recently described as a marker for regeneration-competent myoblasts. We previously determined that expression of Sca-1/Ly-6A is transiently upregulated during myocyte cell-cycle withdrawal; however, a specific function for Sca-1 in myogenesis has not been described. Here, we show that Sca-1 expression on the surface of a subpopulation of differentiating C2C12 myoblasts is maximal at the time of cell-cycle withdrawal, and that blocking Sca-1 with monoclonal antibodies or downregulating Sca-1 expression by antisense both promotes proliferation and inhibits myotube formation. Downregulating Sca-1 expression derepresses Fyn at the time of myoblast cell-cycle withdrawal, and dominant-negative and constitutively active Fyn mutants rescue and recapitulate the Sca-1 antisense phenotype, respectively. This suggests a Fyn-mediated mechanism for Sca-1 action. Thus, we demonstrate an unprecedented role for Sca-1 in early myogenesis in C2C12 cells, and propose a novel pathway from the myoblast cell surface to intracellular signaling networks controlling proliferation versus differentiation in mammalian muscle. These findings suggest that, beyond its role as a marker for muscle progenitors, Sca-1 may be an important therapeutic target for promoting muscle regeneration.
