Abstract
Fibrosis is considered as a central factor in the loss of renal function in chronic kidney diseases. The origin of fibroblasts and myofibroblasts that accumulate in the interstitium of the diseased kidney is still a matter of debate. It has been shown that accumulation of myofibroblasts in inflamed and fibrotic kidneys is associated with upregulation of fibroblast-specific protein 1 (FSP1, S100A4), not only in the renal interstitium but also in the injured renal epithelia. The tubular expression of FSP1 has been taken as evidence of myofibroblast formation by epithelial-mesenchymal transition (EMT). The identity of FSP1/S100A4 cells has not been defined in detail. We originally intended to use FSP1/S100A4 as a marker of putative EMT in a model of distal tubular injury. However, since the immunoreactivity of FSP1 did not seem to fit with the distribution and shape of fibroblasts or myofibroblasts, we undertook the characterization of FSP1/S100A4-expressing cells in the interstitium of rodent kidneys. We performed immunolabeling for FSP1/S100A4 on thin cryostat sections of perfusion-fixed rat and mouse kidneys with peritubular inflammation, induced by thiazides and glomerulonephritis, respectively, in combination with ecto-5'-nucleotidase (5'NT), recognizing local cortical peritubular fibroblasts, with CD45, MHC class II, CD3, CD4 and Thy 1, recognizing mononuclear cells, with alpha smooth muscle actin (alphaSMA), as marker for myofibroblasts, and vimentin for intracellular intermediate filaments in cells of mesenchymal origin. In the healthy interstitium of rodents the rare FSP1/S100A4+ cells consistently co-expressed CD45 or lymphocyte surface molecules. Around the injured distal tubules of rats treated for 3-4 days with thiazides, FSP1+/S100A4+, 5'NT+, alphaSMA+, CD45+ and MHC class II+ cells accumulated. FSP1+/S100A4+ cells consistently co-expressed CD45. In the inflamed regions, alphaSMA was co-expressed by 5'NT+ cells. In glomerulonephritic mice, FSP1+/S100A4+ cells co-expressed Thy 1, CD4 or CD3. Thus, in the inflamed interstitium around distal tubules of rats and of glomerulonephritic mice, the majority of FSP1+ cells express markers of mononuclear cells. Consequently, the usefulness of FSP1/S100A4 as a tool for detection of (myo)fibroblasts in inflamed kidneys and of EMT in vivo is put into question. In the given rat model the consistent co-expression of alphaSMA and 5'NT suggests that myofibroblasts originate from resident peritubular fibroblasts.

Abstract
Many advanced tumors overexpress and secrete the S100A4 protein that is known to promote angiogenesis and metastasis development. The mechanisms of this effect and the endothelial receptor for S100A4 are both still unknown. Here we report that extracellular S100A4 interacts with annexin II, an endothelial plasminogen co-receptor. Co-localization and direct binding of S100A4 and annexin II were demonstrated, and the binding site was identified in the N-terminal region of annexin II. S100A4 alone or in a complex with annexin II accelerated tissue plasminogen activator-mediated plasminogen activation in solution and on the endothelial cell surface through interaction of the S100A4 C-terminal lysines with the lysine-binding domains of plasminogen. A synthetic peptide corresponding to the N terminus of annexin II prevented S100A4-induced plasmin formation in the endothelial cell culture. Local plasmin formation induced by circulating S100A4 could contribute to tumor-induced angiogenesis and metastasis formation that makes this protein an attractive target for new anti-cancer and anti-angiogenic therapies.

Abstract
Ovarian cancer remains the fifth leading cause of cancer death for women in the United States. In this study, the gene expression of 20 ovarian carcinomas, 17 ovarian carcinomas metastatic to the omentum, and 50 normal ovaries was determined by Gene Logic Inc. using Affymetrix GeneChip HU_95 arrays containing approximately 12,000 known genes. Differences in gene expression were quantified as fold changes in gene expression in ovarian carcinomas compared to normal ovaries and ovarian carcinoma metastases. Genes up-regulated in ovarian carcinoma tissue samples compared to more than 300 other normal and diseased tissue samples were identified. Seven genes were selected for further screening by immunohistochemistry to determine the presence and localization of the proteins. These seven genes were: the beta8 integrin subunit, bone morphogenetic protein-7, claudin-4, collagen type IX alpha2, cellular retinoic acid binding protein-1, forkhead box J1, and S100 calcium-binding protein A1. Statistical analyses showed that the beta8 integrin subunit, claudin-4, and S100A1 provided the best distinction between ovarian carcinoma and normal ovary tissues, and may serve as the best candidate tumor markers among the seven genes studied. These results suggest that further exploration into other up-regulated genes may identify novel diagnostic, therapeutic, and/or prognostic biomarkers in ovarian carcinoma.

Abstract
Metastasis-promoting Mts1(S100A4) protein belongs to the S100 family of Ca(2+)-binding proteins. A mouse strain with a germ-line inactivation of the S100A4 gene was generated. The mice were viable and did not display developmental abnormalities in the postnatal period. However, an abnormal sex ratio was observed in the litters with the S100A4-/- genotype, raising the possibility of a certain level of embryonic lethality in this strain. In all, 10% of 10-14-month-old S100A4-null animals developed tumors. This is a characteristic feature of mouse strains with inactivated tumor suppressor genes. Spontaneous tumors of S100A4-/- mice were p53 positive. Recently, we have shown that S100A4 interacts with p53 tumor suppressor protein and induces apoptosis. We proposed that impairment of this interaction could affect the apoptosis-promoting function of p53 that is involved in its tumor suppressor activity. The frequency of apoptosis in the spleen of S100A4-/- animals after whole-body gamma-irradiation was reduced compared to the wild-type animals. The same was true for the transcriptional activation of the p53 target genes - waf/p21/cip1 and bax. Taken together, these observations indicate that spontaneous tumors in S100A4-/- mice are a result of functional destabilization of p53 tumor suppressor gene.

Abstract
The extracellular functions of S100 proteins have attracted more attention in recent years. S100 proteins are a group of calcium-binding proteins which exhibit cell- and tissue-specific expression, and different expression levels of members from this family have been observed in various pathological conditions. The reported extracellular functions of S100 proteins include the ability to enhance neurite outgrowth, involvement in inflammation, and motility of tumour cells. In our previous study, we reported translocation of S100A13 in response to the elevated intracellular calcium levels induced by angiotensin II. In order to investigate potential effects of extracellular S100A13, recombinant S100A13 was used here to stimulate human endothelial cells. Addition of extracellular S100A13 to the cells resulted in both endogenous protein translocation and protein uptake from the extracellular space. To test specificity of this effect, addition of various other S100 proteins was also performed. Interestingly, translocation of specific S100 proteins was only observed when the cells were stimulated with the same extracellular S100 protein. Since the receptor for advanced glycation end products (RAGE) is a putative cell surface receptor for S100 proteins and is involved in various signal transduction pathways, we next investigated the interaction between the receptor and extracellular S100 proteins. We show here that NF-kappaB which is a downstream regulator in RAGE-mediated transduction pathways can be activated by addition of extracellular S100 proteins, and translocation of S100 proteins was inhibited by soluble RAGE. These experiments suggest a common cell surface receptor for S100 proteins on endothelial cells even though intracellular translocation induced by extracellular S100 proteins is specific.

Abstract
AbstractHuman tissue factor pathway inhibitor-2 (TFPI-2) is a matrix-associated Kunitz inhibitor that inhibits the plasmin- and trypsin-mediated activation of zymogen matrix metalloproteinases involved in tumor progression, invasion, and metastasis. To directly assess its role in tumor growth and metastasis in vivo, we stably transfected HT-1080 fibrosarcoma cells expressing either fully active wild-type human TFPI-2 (WT) or inactive R24Q TFPI-2 (QT) and examined their ability to form tumors and metastasize in athymic mice in comparison to mock-transfected cells (MT). MT and QT fibrosarcoma tumors grew 2 to 3 times larger than WT tumors. Tumor metastasis was confined to the lung and was observed in 75% of mice treated with either MT or QT cells, whereas only 42% of mice treated with WT cells developed lung metastases. Real-time quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) analyses of each tumor group revealed 3- to 6-fold lower levels of murine vascular endothelial growth factor gene expression in WT tumors in relation to either MT or QT tumors. Comparative tumor gene expression analysis revealed that several human genes implicated in oncogenesis, invasion, metastasis, apoptosis, and angiogenesis had significantly altered levels of expression in WT tumors. Our collective data demonstrate that secretion of inhibitory TFPI-2 by a highly metastatic tumor cell markedly inhibits its growth and metastasis in vivo by regulating pericellular extracellular matrix (ECM) remodeling and angiogenesis.

Abstract
Elevated levels of the calcium-binding protein S100A4 have been causally linked to the metastatic spread of breast cancer cells in several in vitro and in vivo model systems and, more recently, correlated with patient death in a series of human breast cancer specimens. In transgenic mice expressing MMTV-neu transgenes in mammary gland, additional expression of S100A4 transgenes results in an enhanced metastatic capability. Despite this phenotypic difference arising from elevated S100A4, it is now shown that the primary breast tumours in all mice examined are histopathologically very similar and resemble those human tumours associated with elevated c-erbB-2. Using a panel of genes identified by suppression subtractive hybridization of cDNAs from individual primary tumours and a metastasis, some cDNAs were found to exhibit a differential pattern of expression associated with the expression of S100A4 protein (including osteopontin, S100A9, claudin 2 and several Expressed Sequence Tags sequences). Whilst confirming differential expression of these genes, it was demonstrated that individual primary tumours of matched transgenic status, histology and grade exhibit some degree of heterogeneity at the mRNA level by reverse Northern and Northern hybridizations. This intertumour heterogeneity of mRNA level was confirmed by cDNA array analysis and suggests that even in a transgenic model, which exhibits far less variation than the human disease, there may be multiple mechanisms of disease progression.

Abstract
Microarray technology provides important information for diagnostic, prognostic, and even therapeutic applications. Several S100 proteins have been proposed to play important roles in tumor progression and are recognized as potential tumor markers. To substantiate these limited earlier findings, we screened hundreds of tumor specimens from patients of eight different tumor types using tissue microarrays. The results validated the expression of S100A4, S100A6, and S100B in specific tumor types. A significant S100A2 expression was observed in lymphoma biopsies, which implies a possible link between this S100 protein and lymphoma development. In contrast, S100A5 and S100A12 were not significantly expressed in any of the tumor tissues tested. Interestingly, expression of RAGE (receptor for advanced glycation end products) was found in breast and lung tumor tissues where abundant S100A4 and S100A6 expression was also observed. This suggests a possible role of RAGE-mediated signal transduction in the development of these particular cancers.

Abstract
To investigate changes in gene expression associated with ERBB2, expression profiling of immortalized human mammary luminal epithelial cells and variants expressing a moderate and high level of ERBB2 has been carried out using cDNA microarrays corresponding to approximately 6000 unique genes/ESTs. A total of 61 significantly up- or downregulated (2.0-fold) genes were identified and further validated by RT-PCR analysis as well as microarray comparisons with a spontaneously ERBB2- overexpressing breast cancer cell line and ERBB2-positive primary breast tumors. The expression and clinical relevance of proteins predicted to be associated with ERBB2 overexpression in breast cancers were analysed together with their clinical relevance by antibody screening using a tissue array. Differentially regulated genes include those involved in cell-matrix interactions including proline 4-hydroxylase (P4HA2), galectin 1 (LGALS1) and galectin 3 (LGALS3), fibronectin 1 (FN1) and p-cadherin (CDH3), and cell proliferation (CRIP1, IGFBP3) and transformation (S100P, S100A4). A number of genes associated with MYC signalling were also differentially expressed, including NDRG1, USF2 and the epithelial membrane proteins 1 and 3 (EMP1, EMP3). These data represent profiles of the transcriptional changes associated with ERBB2-related pathways in the breast, and identify novel and potentially useful targets for prognosis and therapy.

Abstract
BACKGROUND & AIMS Prognostication in colon cancer almost exclusively still rests on the tumor stage. Furthermore, tumor-derived markers to improve discrimination of low- and high-risk subtypes generally are not in use. S100A4 has been reported to be associated with invasion and metastasis; however, no data are available on its prognostic value in colorectal carcinoma. Therefore, we investigated the prognostic significance of immunohistochemical S100A4 expression in colorectal carcinoma compared with clinicopathologic parameters and expression of cell-cycle markers p16, p21, p27, p53, Ki-67, and RB. METHODS Archival tissue from 709 patients with colorectal cancer were retrieved, applied in tissue array technology, and investigated immunohistochemically. Univariate and multivariate survival analyses were carried out on all investigated parameters. RESULTS Sixteen percent of cases showed high; 31%, low; and 53%, no S100A4 expression. In Kaplan-Meier analysis, S100A4 positively stained cases showed a significantly decreased survival time compared with negatively stained cases (P < 0.0001). In multivariate regression analysis, S100A4 expression emerged as a highly significant independent parameter (P < 0.001) with the highest relative-risk factor among other covariates. Nodal status (pN) lost its prognostic value if S100A4 was added to the model. High S100A4 expression was associated with tumor stage pT3/4, secondary metastasis, women, p16, and RB expression. CONCLUSIONS S100A4 expression represents a highly significant prognostic marker in colorectal carcinoma, which is able to identify a subset of patients at high risk. In this respect, it is superior to established prognostic markers such as nodal status, pT stage, and p53 expression.
