    Oligoarray analysis of a matched pair of prostate cancer and normal cell lines derived from the same radical prostatectomy specimen identified 113 candidate hypomethylated genes that were overexpressed in the cancer cells and contained CpG islands. Hypomethylation of wingless-related MMTV integration site 5A (WNT5A), S100 calcium-binding protein P (S100P) and cysteine-rich protein 1(CRIP1) was confirmed in the cancer cells by bisulfite sequencing. Treatment of the corresponding normal prostate epithelial cells 1542-NPTX with the DNA methyltransferase inhibitor 5-Aza-2'-deoxycytidine (5-aza-CdR) induced higher levels of mRNA expression and partial loss of methylation on these genes. Primary prostate cancers were tested using methylation-specific polymerase chain reaction. WNT5A was hypomethylated in 11/17 (65%) tumors, S100P in 8/16 (50%) and CRIP1 in 13/20 (65%). Bisulfite sequencing of a section of the 5' untranslated region (UTR) of WNT5A revealed that three CpG sites (15, 24 and 35) were consistently methylated (93%) in the normal cell line and normal tissues, but not in the prostate cancer cell line and eight primary prostate cancers. Multiple putative binding sites for the transcription factors SP1 and AP-2 were found adjacent to CpG sites 15 and 24. A putative c-Myb binding site was located within the CpG site 35. Anti-c-Myb antibody co-precipitation with WNT5A was methylation-sensitive in 1542-NPTX cells. It is likely that an epigenetic mechanism regulates WNT5A expression in prostate cancer.

    Cell signaling mechanisms often transmit information via posttranslational protein modifications, most importantly reversible protein phosphorylation. Here we develop and apply a general mass spectrometric technology for identification and quantitation of phosphorylation sites as a function of stimulus, time, and subcellular location. We have detected 6,600 phosphorylation sites on 2,244 proteins and have determined their temporal dynamics after stimulating HeLa cells with epidermal growth factor (EGF) and recorded them in the Phosida database. Fourteen percent of phosphorylation sites are modulated at least 2-fold by EGF, and these were classified by their temporal profiles. Surprisingly, a majority of proteins contain multiple phosphorylation sites showing different kinetics, suggesting that they serve as platforms for integrating signals. In addition to protein kinase cascades, the targets of reversible phosphorylation include ubiquitin ligases, guanine nucleotide exchange factors, and at least 46 different transcriptional regulators. The dynamic phosphoproteome provides a missing link in a global, integrative view of cellular regulation.

    Department of Cell Biology, Harvard Medical School, 240 Longwood Ave., Boston, Massachusetts 02115, USA.

    Data analysis and interpretation remain major logistical challenges when attempting to identify large numbers of protein phosphorylation sites by nanoscale reverse-phase liquid chromatography/tandem mass spectrometry (LC-MS/MS) (Supplementary Figure 1 online). In this report we address challenges that are often only addressable by laborious manual validation, including data set error, data set sensitivity and phosphorylation site localization. We provide a large-scale phosphorylation data set with a measured error rate as determined by the target-decoy approach, we demonstrate an approach to maximize data set sensitivity by efficiently distracting incorrect peptide spectral matches (PSMs), and we present a probability-based score, the Ascore, that measures the probability of correct phosphorylation site localization based on the presence and intensity of site-determining ions in MS/MS spectra. We applied our methods in a fully automated fashion to nocodazole-arrested HeLa cell lysate where we identified 1,761 nonredundant phosphorylation sites from 491 proteins with a peptide false-positive rate of 1.3%.

    By analyzing 1,780,295 5'-end sequences of human full-length cDNAs derived from 164 kinds of oligo-cap cDNA libraries, we identified 269,774 independent positions of transcriptional start sites (TSSs) for 14,628 human RefSeq genes. These TSSs were clustered into 30,964 clusters that were separated from each other by more than 500 bp and thus are very likely to constitute mutually distinct alternative promoters. To our surprise, at least 7674 (52%) human RefSeq genes were subject to regulation by putative alternative promoters (PAPs). On average, there were 3.1 PAPs per gene, with the composition of one CpG-island-containing promoter per 2.6 CpG-less promoters. In 17% of the PAP-containing loci, tissue-specific use of the PAPs was observed. The richest tissue sources of the tissue-specific PAPs were testis and brain. It was also intriguing that the PAP-containing promoters were enriched in the genes encoding signal transduction-related proteins and were rarer in the genes encoding extracellular proteins, possibly reflecting the varied functional requirement for and the restricted expression of those categories of genes, respectively. The patterns of the first exons were highly diverse as well. On average, there were 7.7 different splicing types of first exons per locus partly produced by the PAPs, suggesting that a wide variety of transcripts can be achieved by this mechanism. Our findings suggest that use of alternate promoters and consequent alternative use of first exons should play a pivotal role in generating the complexity required for the highly elaborated molecular systems in humans.

    To determine the clinical significance of gene promoter methylation in hepatocellular carcinoma (HCC), we examined in clinical samples the methylation status of those promoters that showed elevated activity in hepatoma cell lines after 5-aza-2'-deoxycytidine treatment.

    Methods: Regarding the genes with promoter hypermethylation in the cell lines, their expression levels and methylation status in HCC and non-HCC tissues were assessed by semiquantitive RT-PCR and methylation-specific PCR. To confirm the result, the expression levels and methylation status in 16 additional HCC and non-HCC tissues were assessed.

    Results: The promoter regions of caveolin 1 (CAV1), cysteine and glycine-rich protein 1 (CSRP1), Kruppel-like factor 6 (KLF6), myosin (light polypeptide 9) (MYL9), and transgelin (TAGLN) were highly methylated in the cell lines. CAV1 and CSRP1 were methylated in HCC more frequently than in non-HCC. KLF6, MYL9, and TAGLN were fully methylated in both HCC and non-HCC. Using additional clinical samples, downregulation of CAV1 and CSRP1 was observed in 38 and 56%, respectively, of the 16 HCC samples and aberrant methylation of CAV1 and CSRP1 was observed in 56% of HCC in both cases.

    Conclusion: CAV1 and CSRP1 were inactivated in HCC by aberrant methylation and they may serve as important biomarkers of malignancy.

    The National Institutes of Health's Mammalian Gene Collection (MGC) project was designed to generate and sequence a publicly accessible cDNA resource containing a complete open reading frame (ORF) for every human and mouse gene. The project initially used a random strategy to select clones from a large number of cDNA libraries from diverse tissues. Candidate clones were chosen based on 5'-EST sequences, and then fully sequenced to high accuracy and analyzed by algorithms developed for this project. Currently, more than 11,000 human and 10,000 mouse genes are represented in MGC by at least one clone with a full ORF. The random selection approach is now reaching a saturation point, and a transition to protocols targeted at the missing transcripts is now required to complete the mouse and human collections. Comparison of the sequence of the MGC clones to reference genome sequences reveals that most cDNA clones are of very high sequence quality, although it is likely that some cDNAs may carry missense variants as a consequence of experimental artifact, such as PCR, cloning, or reverse transcriptase errors. Recently, a rat cDNA component was added to the project, and ongoing frog (Xenopus) and zebrafish (Danio) cDNA projects were expanded to take advantage of the high-throughput MGC pipeline.

    As a base for human transcriptome and functional genomics, we created the "full-length long Japan" (FLJ) collection of sequenced human cDNAs. We determined the entire sequence of 21,243 selected clones and found that 14,490 cDNAs (10,897 clusters) were unique to the FLJ collection. About half of them (5,416) seemed to be protein-coding. Of those, 1,999 clusters had not been predicted by computational methods. The distribution of GC content of nonpredicted cDNAs had a peak at approximately 58% compared with a peak at approximately 42%for predicted cDNAs. Thus, there seems to be a slight bias against GC-rich transcripts in current gene prediction procedures. The rest of the cDNAs unique to the FLJ collection (5,481) contained no obvious open reading frames (ORFs) and thus are candidate noncoding RNAs. About one-fourth of them (1,378) showed a clear pattern of splicing. The distribution of GC content of noncoding cDNAs was narrow and had a peak at approximately 42%, relatively low compared with that of protein-coding cDNAs.

  • The CRP/MLP/TLP family of LIM domain proteins: acting by connecting.

    Institute of Clinical Chemistry and Pathobiochemistry, RWTH- University Hospital, D-52074 Aachen, Germany. rweiskirchen@ukaachen.de

    In vertebrates, members of the cysteine-rich protein (CRP) family are characterized by the presence of two LIM domains linked to short glycine-rich repeats. These proteins mediate protein-protein interactions and are of fundamental importance for cell differentiation, cytoskeletal remodeling, and transcriptional regulation. To date, a vast amount of information about vertebrate CRPs has become available, including their biological functions, interacting partners, and three-dimensional structures. Compatible with a molecular adapter role, structural data reveal that the LIM domains within these proteins represent completely independent folded units bridged by flexible linker regions. The physiological roles for individual CRPs was determined by targeted gene disruption analysis and by identification of common and specific binding partners by means of yeast and mammalian two-hybrid screens. Several CRP-like LIM domain proteins with close structural and sequence similarity were identified in arthropods, protozoas and plants, supporting the notion that this subset of LIM domain proteins has been highly conserved over the span of evolution thereby emphasizing the importance of their function.

    Department of Biochemistry and Molecular Biology, University of Southern Denmark, Campusvej 55, DK-5230, Odense M, Denmark.

    Background: The nucleolus is a subnuclear organelle containing the ribosomal RNA gene clusters and ribosome biogenesis factors. Recent studies suggest it may also have roles in RNA transport, RNA modification, and cell cycle regulation. Despite over 150 years of research into nucleoli, many aspects of their structure and function remain uncharacterized.

    Results: We report a proteomic analysis of human nucleoli. Using a combination of mass spectrometry (MS) and sequence database searches, including online analysis of the draft human genome sequence, 271 proteins were identified. Over 30% of the nucleolar proteins were encoded by novel or uncharacterized genes, while the known proteins included several unexpected factors with no previously known nucleolar functions. MS analysis of nucleoli isolated from HeLa cells in which transcription had been inhibited showed that a subset of proteins was enriched. These data highlight the dynamic nature of the nucleolar proteome and show that proteins can either associate with nucleoli transiently or accumulate only under specific metabolic conditions.

    Conclusions: This extensive proteomic analysis shows that nucleoli have a surprisingly large protein complexity. The many novel factors and separate classes of proteins identified support the view that the nucleolus may perform additional functions beyond its known role in ribosome subunit biogenesis. The data also show that the protein composition of nucleoli is not static and can alter significantly in response to the metabolic state of the cell.

  • Fine mapping of the alpha-actinin binding site within cysteine-rich protein.

    Harper BD, Beckerle MC and Pomiès P

    Department of Biology and Huntsman Cancer Institute, University of Utah, Salt Lake City, UT 84112-5550, USA.

    The cysteine-rich proteins (CRPs) are a family of highly conserved LIM (an acronym derived from the three gene products lin-11, isl-1 and mec-3) domain proteins that have been implicated in muscle differentiation. All CRP family members characterized so far have been shown to interact with the filamentous actin cross-linker alpha-actinin. The region of CRP required for this interaction has previously been broadly mapped to the molecule's N-terminal half. Here we report that the alpha-actinin-binding region of CRP, which we have mapped by using a combination of blot overlay and Western immunoblot techniques, is confined to an 18-residue sequence occurring within the protein's N-terminal glycine-rich repeat. A site-directed mutagenesis analysis of the binding region has revealed the critical importance of a single lysine residue (lysine 65 in human CRP1). Alterations at this site lead to a 10-fold decrease in alpha-actinin binding in comparison with wild-type CRP. The critical lysine residue localizes within a short alpha-helix, raising the possibility that mutagenesis-induced alterations in alpha-actinin-binding capacity might be attributed to the disruption of a key structural element.

  • Abundant cysteine-rich protein-1 is localized in the stromal compartment of the human prostate.

    The cysteine-rich protein-1 (CRP1) is one of the major proteins of the human prostate. Because of the suspected importance of that protein in cell proliferation and differentiation, its expression was investigated in the prostate, prostatic cancer cells, and other organs of the body. At the mRNA level, the highest concentrations of CRP1 were found in the prostate and the colon followed by the brain and the testis. It was virtually absent from the spleen, liver, heart, and kidney. Prostatic cancer cells PC-3, DU-145, and LNCaP also expressed CRP1 mRNA but virtually no protein. CRP1 protein localization in tissues was determined by immunohistochemical analysis using polyclonal antibodies developed against recombinant CRP1 protein. Strong positive cytoplasmic immunoreactions were observed only in the stromal compartment of the prostate and of other smooth muscle-rich tissues without significant staining in any secretory epithelium. These results, along with previously reported data of colocalization of CRP1 with stress fibers and adhesion plaques, suggest that the main function of CRP1 may be structural.

  • The LIM/double zinc-finger motif functions as a protein dimerization domain.

    Feuerstein R, Wang X, Song D, Cooke NE and Liebhaber SA

    Department of Genetics, University of Pennsylvania School of Medicine, Philadelphia 19104-6145.

    Protein-protein interactions resulting in dimerization and heterodimerization are of central importance in the control of gene expression and cell function. Proteins that share the 52-residue LIM/double zinc-finger domain are involved in a wide range of developmental and cellular controls. Some of these functions have been hypothesized to involve protein dimerization. In the present report we demonstrate, using both in vitro and cell-based studies, that a representative LIM protein, human cysteine-rich protein (hCRP), can efficiently homodimerize. The dimerization ability of hCRP is mapped to the LIM domains, can be transferred to an unrelated protein by fusion of a single minimal LIM/double zinc-finger segment, occurs in the absence as well as the presence of DNA, and appears to depend on coordination of two zinc atoms in the finger doublet. These observations support a specific role for protein dimerization in the function of proteins containing the LIM/double zinc-finger domain and expand the general spectrum of potential interactions mediated by zinc-finger motifs.

  • Analysis of the human cysteine-rich protein gene (CSRP), assignment to chromosome 1q24-1q32, and identification of an associated MspI polymorphism.

    Wang X, Ray K, Szpirer J, Levan G, Liebhaber SA and Cooke NE

    Department of Medicine, Howard Hughes Medical Institute, University of Pennsylvania, Philadelphia 19104.

    The human cysteine-rich protein (hCRP) is encoded by a highly conserved and widely expressed serum-inducible immediate early response gene. hCRP contains two copies of the "LIM/double zinc-finger" motif. Using a characterized hCRP cDNA probe, we demonstrate that the human CRP gene (CSRP) is present in a single copy and that both mouse and human genomes contain one or more CRP-related genes detected by hybridization at low stringency. Using a panel of human x rodent somatic cell hybrids, the hCRP locus is assigned to chromosome 1. In situ hybridization of 3H-labeled CRP cDNA to human metaphase chromosomes confirms this assignment and permits regional localization to bands 1q24-1q32. A common MspI polymorphism is identified and mapped to intron 4 of the hCRP gene. The chromosomal localization and restriction site polymorphism should prove useful in future studies of the function of this gene.

  • Human cysteine-rich protein. A member of the LIM/double-finger family displaying coordinate serum induction with c-myc.

    Wang X, Lee G, Liebhaber SA and Cooke NE

    Department of Medicine, University of Pennsylvania, Philadelphia 19104.

    We previously reported the structure of the placentally derived human cysteine-rich (h crp) cDNA and demonstrated that it encodes a highly conserved and widely distributed zinc finger-like protein. We now report that the expression of both the mouse and human crp genes is induced as a primary response to serum in quiescent Balb/c 3T3 cells and in human fibroblasts. The profile of this primary response is remarkably parallel to that of c-myc in the Balb/c 3T3 cell line. The structure of the 23.2-kilobase h crp gene demonstrates that it is a member of a gene superfamily encoding proteins sharing a highly characteristic 52-amino acid "LIM/double-finger" motif. The evolutionarily conserved structure of cysteine-rich protein, its structural similarity to a number of developmentally critical proteins, its distinctive tissue distribution, and its primary response to early events in the cell cycle suggest that crp plays an important role in cell function.

  • Characterization of a human cDNA encoding a widely expressed and highly conserved cysteine-rich protein with an unusual zinc-finger motif.

    Liebhaber SA, Emery JG, Urbanek M, Wang XK and Cooke NE

    Howard Hughes Medical Institute, University of Pennsylvania, Philadelphia 19104.

    A human term placental cDNA library was screened at low stringency with a human prolactin cDNA probe. One of the cDNAs isolated hybridizes to a 1.8 kb mRNA present in all four tissues of the placenta as well as to every nucleated tissue and cell line tested. The sequence of the full-length cDNA was determined. An extended open reading frame predicted an encoded protein product of 20.5 kDa. This was directly confirmed by the in vitro translation of a synthetic mRNA transcript. Based upon the characteristic placement of cysteine (C) and histidine (H) residues in the predicted protein structure, this molecule contains four putative zinc fingers. The first and third fingers are of the C4 class while the second and fourth are of the C2HC class. Based upon sequence similarities between the first two and last two zinc fingers and sequence similarities to a related rodent protein, cysteine-rich intestinal protein (CRIP), these four finger domains appear to have evolved by duplication of a preexisting two finger unit. Southern blot analyses indicate that this human cysteine-rich protein (hCRP) gene has been highly conserved over the span of evolution from yeast to man. The characteristics of this protein suggest that it serves a fundamental role in cellular function.
