Abstract
OBJECTIVE The ductus arteriosus (DA) is a fetal artery connecting the aorta and pulmonary arteries. Progressive matrix remodeling, that is, intimal thickening (IT), occurs in the subendothelial region of DA to bring anatomic DA closure. IT is comprised of multiple ECMs (extracellular matrices) and migrated smooth muscle cells (SMCs). Because glycoprotein fibulin-1 binds to multiple ECMs and regulates morphogenesis during development, we investigated the role of fibulin-1 in DA closure. Approach and Results: Fibulin-1-deficient (Fbln1-/-) mice exhibited patent DA with hypoplastic IT. An unbiased transcriptome analysis revealed that EP4 (prostaglandin E receptor 4) stimulation markedly increased fibulin-1 in DA-SMCs via phospholipase C-NFκB (nuclear factor κB) signaling pathways. Fluorescence-activated cell sorting (FACS) analysis demonstrated that fibulin-1 binding protein versican was derived from DA-endothelial cells (ECs). We examined the effect of fibulin-1 on directional migration toward ECs in association with versican by using cocultured DA-SMCs and ECs. EP4 stimulation promoted directional DA-SMC migration toward ECs, which was attenuated by either silencing fibulin-1 or versican. Immunofluorescence demonstrated that fibulin-1 and versican V0/V1 were coexpressed at the IT of wild-type DA, whereas 30% of versican-deleted mice lacking a hyaluronan binding site displayed patent DA. Fibulin-1 expression was attenuated in the EP4-deficient mouse (Ptger4-/-) DA, which exhibits patent DA with hypoplastic IT, and fibulin-1 protein administration restored IT formation. In human DA, fibulin-1 and versican were abundantly expressed in SMCs and ECs, respectively. CONCLUSIONS Fibulin-1 contributes to DA closure by forming an environment favoring directional SMC migration toward the subendothelial region, at least, in part, in combination with EC-derived versican and its binding partner hyaluronan.

Abstract
Fibulins are a group of extracellular matrix proteins of which many are present in high amounts in the cardiovascular system. They share common biochemical properties and are often found in relation to basement membranes or elastic fibers. Observations in humans with specific mutations in fibulin genes, together with results from genetically engineered mice and data from human cardiovascular tissue suggest that the fibulin family of proteins play important functional roles in the cardiovascular system. Moreover, fibulin-1 circulates in high concentrations in plasma and may function as a cardiovascular disease marker.

High-resolution two-dimensional gel electrophoresis analysis of atrial tissue proteome reveals down-regulation of fibulin-1 in atrial fibrillation. Int J Cardiol 2010; 150:283-90.

Abstract
BACKGROUND Atrial fibrillation (AF) is the most common cardiac arrhythmia found in clinical practice. We combined high-resolution two-dimensional gel electrophoresis (2-DE) and mass spectrometry (MS) to compare the atrial proteome of subjects with AF versus controls with sinus rhythm (SR). Our aim was to identify novel differentially regulated proteins that could be related to the development of the arrhythmia. METHODS Human atrial appendage tissue samples from patients undergoing heart surgery with AF or SR were analyzed by high-resolution 2-DE. Proteins of interest were identified by MS and validated by western blotting and inmunohistochemistry. RESULTS Our analysis allowed the detection of over 2300 protein spots per gel. Following differential image analysis, we found 22 spot differences between the AF and SR groups in the 4-7 isoelectric point range, leading to the identification of 15 differentially regulated proteins. The main group of proteins identified was that of heat shock proteins (HSPs), including TRAP-1, HspB3, HspΒ6 and AHA1. Some of the differences detected between AF and SR for the above proteins were due to post-translational modifications. In addition, we identified the structural protein fibulin-1 as down-regulated in atrial tissue from AF patients. CONCLUSIONS High-resolution 2-DE analysis of human atrial tissue revealed that AF is associated with changes in structural proteins and an important number of HSPs. The lower expression of the structural protein fibulin-1 in atrial tissue from AF patients might reflect the myocardial structural changes that take place in the arrhythmia.

Abstract
Here we report that mouse embryos homozygous for a gene trap insertion in the fibulin-1 (Fbln1) gene are deficient in Fbln1 and exhibit cardiac ventricular wall thinning and ventricular septal defects with double outlet right ventricle or overriding aorta. Fbln1 nulls also display anomalies of aortic arch arteries, hypoplasia of the thymus and thyroid, underdeveloped skull bones, malformations of cranial nerves and hemorrhagic blood vessels in the head and neck. The spectrum of malformations is consistent with Fbln1 influencing neural crest cell (NCC)-dependent development of these tissues. This is supported by evidence that Fbln1 expression is associated with streams of cranial NCCs migrating adjacent to rhombomeres 2-7 and that Fbln1-deficient embryos display patterning anomalies of NCCs forming cranial nerves IX and X, which derive from rhombomeres 6 and 7. Additionally, Fbln1-deficient embryos show increased apoptosis in areas populated by NCCs derived from rhombomeres 4, 6 and 7. Based on these findings, it is concluded that Fbln1 is required for the directed migration and survival of cranial NCCs contributing to the development of pharyngeal glands, craniofacial skeleton, cranial nerves, aortic arch arteries, cardiac outflow tract and cephalic blood vessels.

Abstract
Fibulin-1 is a secreted protein associated with elastic matrix fibres and basement membranes. It plays a role in stabilizing blood vessels and can also regulate cell motility and invasiveness. We studied the regulation of the fibulin-1 gene in the rat and human endometrium, an organ where cyclic tissue remodeling and angiogenesis take place. The rat fibulin-1C and -1D-specific DNA sequences were first identified and a comparison of the deduced amino acid sequence with the mouse and human counterparts showed a very strong conservation. The exon-intron structure was also maintained. Primers were derived for RT-PCR analysis of fibulin-1 expression in rat endometrium. The highest levels of fibulin-1C and -1D transcripts were measured at metestrous and diestrous, and in early pregnancy at day 3 post-coitum. In vivo studies showed stimulation of endometrial fibulin-1D expression after estrogen application, an effect prevented by parallel treatment with progesterone. Analysis of human endometrial tissues indicated that the fibulin-1D transcript levels were higher during the mid-secretory phase than during the proliferative and early secretory phases. Cultured human endometrial stromal cells treated with progesterone responded with a dramatic increase of fibulin-1 protein expression. This was enhanced by parallel treatment with epidermal growth factor and prevented by application of the antiprogestin RU486. Altogether the results show a cycle-dependent regulation of endometrial fibulin-1 expression controlled by both progesterone and estrogen. Based on its implication in tissue remodeling and angiogenesis, fibulin-1 may play an important role in endometrial receptivity for embryo implantation.

Abstract
Fibulin-1 is an extracellular matrix protein induced by estradiol in estrogen receptor (ER) positive ovarian cancer cell lines. Alternative splicing of fibulin-1 mRNA results in four different variants named A, B, C and D that may have distinct biological functions. We studied the relative expression of fibulin-1 mRNA variants and their estrogen regulation in human ovarian cancer cells. In ovarian tissues and cancer cell lines, fibulin-1C and -1D are the predominant forms, whereas fibulin-1A and -1B are weakly expressed. We developed a competitive PCR assay based on coamplification of fibulin-1C and -1D to study the relative expression of these fibulin-1 variants in human ovarian samples. In ovarian cancer cell lines and ovarian cancer samples, there was a marked increase in the fibulin-1C:1D and fibulin-1C:HPRT mRNA ratios as compared to normal ovaries. In the BG1 estrogen receptor positive ovarian cancer cell line, fibulin-1C mRNA was induced by estradiol in a dose- and time-dependent manner. Since others and we have previously shown an increased expression of ERalpha as compared to ERbeta in ovarian cancer cells, we investigated whether ERalpha or ERbeta is involved in this induction. For this aim, MDA-MB-231 breast cancer cell line, which expresses both low basal levels of ERs and fibulin-1, was infected with recombinant ERalpha or ERbeta encoding adenovirus and treated with estradiol. Fibulin-1C was induced by estradiol in ERalpha- but not ERbeta-infected cells, suggesting that fibulin-1C induction is mediated through ERalpha. In ovarian tumors, a trend towards a correlation between fibulin-1C and ERalpha expression levels was noted. In conclusion, this study showed an increased fibulin-1C:-1D mRNA ratio in ovarian cancer cells as compared to normal ovaries. This finding suggests that the C variant may be involved in ovarian carcinogenesis. Fibulin-1C overexpression may thus be a clue for the understanding of a putative role of estrogens in ERalpha promoted ovarian tumor progression.

Abstract
Molecular analysis of the reciprocal chromosomal translocation t(12;22)(p11.2;q13.3) cosegregating with a complex type of synpolydactyly showed involvement of an alternatively spliced exon of the fibulin-1 gene (FBLN1 located in 22q13.3) and the C12orf2 (HoJ-1) gene on the short arm of chromosome 12. Investigation of the possible functional involvement of the fibulin-1 protein (FBLN1) in the observed phenotype showed that FBLN1 is expressed in the extracellular matrix (ECM) in association with the digits in the developing limb. Furthermore, fibroblasts derived from patients with the complex type of synpolydactyly displayed alterations in the level of FBLN1-D splice variant incorporated into the ECM and secreted into the conditioned culture medium. By contrast, the expression of the FBLN1-C splice variant was not perturbed in the patient fibroblasts. Based on these findings, we propose that the t(12;22) results in haploinsufficiency of the FBLN1-D variant, which could lead to the observed limb malformations.

Abstract
Fibulin-1, an extracellular matrix protein, is secreted by human ovarian metastatic cancer cell lines under estrogen stimulation. Fibulin-1 expression was quantified by immunohistochemistry and computer-aided image analysis in 44 human ovarian epithelial tumors and 14 normal ovaries. The fibulin-1 staining intensity in proximal stroma, close to the surface of epithelial cells and tumor cells, progressively increased from normal ovaries to serous carcinomas. In all lesions, excluding cystadenomas, fibulin-1 accumulation was higher in proximal stroma than in distant stroma. In situ hybridization demonstrated strong fibulin-1 gene expression in epithelial cells of serous ovarian carcinomas and some cysts. The weak expression of fibulin-1 RNA in some stromal cells of these tumors could not explain the strong fibulin-1 protein accumulation in tumor stroma, which was therefore mostly produced by tumor epithelial cells. In carcinomas, fibulin-1 staining was not correlated with the percentage of estrogen receptor-alpha (ERalpha)-stained nuclei but was inversely correlated with the progesterone receptor. However, in cystadenomas and borderline tumors, both fibulin-1 and ERalpha protein levels increased, in comparison with normal ovaries, suggesting an effect of estrogens in the early steps of tumorigenesis. This fibulin-1 overexpression, demonstrated in vivo in ovarian carcinomas, might be a useful indicator for predicting cancer risk and/or aggressiveness.

Abstract
Ovarian cancers have a high ability to invade the peritoneal cavity and some are stimulated by estrogens. In an attempt to understand the mode of action of estrogens on these cancer cells and to develop new markers, we have characterized estrogen-regulated proteins. This study was aimed at identifying a protein secreted by ovarian cancer cells whose level was increased by estradiol [Galtier-Dereure, F., Capony, F., Maudelonde, T. & Rochefort, H. (1992) J. Clin. Endocrinol. Metab. 75, 1497-1502]. By using microprotein sequencing, the 110-kDa protein was identified as fibulin-1, a protein of the extracellular matrix that binds to fibronectin, laminin, and nidogen. The amount of immunoprecipitated fibulin-1 secreted into the medium and present in the cell extract was increased up to 10-fold by estradiol in three estrogen-responsive ovarian cancer cell lines. By immunohistochemistry fibulin-1 was located in the stroma of several ovarian cancers and cysts. The findings highlight a potential role for fibulin-1 in the spread of ovarian cancer in the peritoneal cavity and/or in distal metastases.

Abstract
Selection of chromosomal sublibraries from total human genomic libraries is critical for chromosome-based physical mapping approaches. We have previously reported a method of screening total human genomic library using flow sorted chromosomal DNA as a hybridization probe and selection of a human chromosome 22-enriched sublibrary from a total human bacterial artificial chromosome (BAC) library (Nucleic Acids Res 1995; 23: 1838-39). We describe here further details of the method of construction as well as characterization of the chromosome 22-enriched sublibrary thus constructed. Nearly 40% of the BAC clones that have been mapped by fluorescence in situ hybridization (FISH) analysis were localized to chromosome 22. By screening the sublibrary using chromosome 22-specific hybridization probes, we estimated that the sublibrary represents at least 2.5 x coverage of chromosome 22. This is in good agreement with the results from FISH mapping experiments. FISH map data also indicate that chromosome 22-specific BACs in the sublibrary represent all the subregions of chromosome 22.
