Abstract
BACKGROUND Aldehyde dehydrogenase 1 (ALDH1) has been characterised as a cancer stem cell marker in different types of tumours. Additionally, it plays a pivotal role in gene regulation and endows tumour cells with augmented chemoresistance. Recently, ALDH1A1 has been described as a prognostic marker in a pancreatic cancer tissue microarray. The aim of this study was to reevaluate the expression of ALDH1A1 as a prognostic marker on whole-mount tissue sections. METHODS Real-time-quantitative-PCR (qRT-PCR) and Western blotting were used to evaluate the expression profile of ALDH1A1 in seven pancreatic cancer cell lines and one non-malignant pancreatic cell line. Immunostaining against ALDH1A1 and Ki-67 was performed on paraffin-embedded samples from 97 patients with pancreatic cancer. The immunohistochemical results were correlated to histopathological and clinical data. RESULTS qRT-PCR and Western blotting revealed a different expression pattern of ALDH1A1 in different malignant and non-malignant pancreatic cell lines. Immunohistochemical analysis demonstrated that ALDH1A1 was confined to the cellular cytoplasm and occurred in 72 cases (74%), whereas it was negative in 25 cases (26%). High expression of ALDH1A1 was significantly correlated to an increased proliferation rate (Spearman correlation, p = 0.01). Univariate and multivariate analyses showed that decreased expression of ALDH1A1 is an independent adverse prognostic factor for overall survival. CONCLUSIONS Immunohistochemical analysis on whole-mount tissue slides revealed that ALDH1A1 is more abundantly expressed in pancreatic cancer than initially reported by a tissue microarray analysis. Moreover, high expression of ALDH1A1 correlated significantly with the proliferation of tumour cells. Intriguingly, this study is the first which identifies low expression of ALDH1A1 as an independent adverse prognostic marker for overall survival in pancreatic cancer.

Abstract
While improved imaging techniques have made it possible to detect focal liver lesions smaller than 1cm in diameter, differentiating benign lesions from hepatocellular carcinoma (HCC) still remains a challenge. To address this problem and obtain a definite diagnosis, needle core biopsies are often performed, leading to an increased need for supportive ancillary techniques in the histopathological assessment of highly differentiated hepatocellular tumors. Here we evaluate the diagnostic value of immunohistologically detected Annexin A2 (ANXA2) expression in highly differentiated liver tumors. ANXA2 is a calcium-dependent phospholipid-binding protein that has been linked to malignant transformation and HCC development. Our data show that adding sinusoidal ANXA2 expression to the already established marker panel (GPC3, GS, and HSP70) increases the accuracy for the detection of well-differentiated HCC (74% sensitivity, 100% specificity). In addition, in our series, the combinations ANXA2-GPC3 and ANXA2-GS performed better compared to the other established marker combinations. In conclusion, we suggest that adding ANXA2 to the established diagnostic marker panel increases the reliability and objectivity of HCC diagnosis in liver biopsies.

Abstract
The blue rubber bleb nevus syndrome (BRBNS, syn. bean syndrome) is a rare disease
characterized by multiple cutaneous and gastrointestinal venous malformations
associated with severe bleeding. However, the underlying molecular mechanisms
are unknown and no targeted therapeutic approach exists to date. Here we report
the case of a 19-year-old male patient with severe BRBNS in whom we analyzed the
expression of tyrosine kinases frequently involved in tumor development by
immunohistochemistry (vascular endothelial growth factor receptor-2, stem cell
growth factor receptor (c-kit), platelet-derived growth factor
receptor-β, and stem cell tyrosine kinase-1). A prominent expression of
c-kit was detectable in smaller blood vessels, which also showed a moderate
expression of the proliferation marker MIB1. Surprisingly, other growth factor
receptors stained negatively. We therefore conclude that pharmacological
inhibition of the c-kit signaling pathway in cavernous hemangiomas by selective
kinase inhibitors may offer options in the treatment of BRBNS patients.

Abstract
Abstract
Endosialin is a heavily sialylated C-type lectin. It is a single transmembrane molecule that was identified by two independent studies as an angiogenic endothelial specific marker. However, recent high resolution confocal expression studies by our and other laboratories have revealed that Endosialin is not expressed by endothelial cells but instead by angiogenic blood vessel associated pericytes. Detailed tissue array-based expression profiling validated Endosialin as an oncofetal gene product of the mesenchymal lineage that is hardly detectable in normal tissues but abundantly expressed by tumor vessel-associated pericytes and tumor stromal fibroblasts (myofibroblasts). As such, Endosialin was not just identified as a marker of activated pericytes but based on its exclusive tumor-associated expression also as a novel therapeutic tumor stroma target. Cytokine induction experiments identified Endosialin as a major downstream target of TGFß stimulation. Cellular siRNA-based loss-of-function experiments unravelled a role of Endosialin in the regulation of mesenchymal cell adhesion, migration and proliferation. These findings prompted experiments aimed at identifying the extracellular ligand of Endosialin. Using Endosialin-Fc as an affinity probe, the metastasis associated molecule Mac-2BP/90K was identified as high affinity extracellular Endosialin ligand. As Endosialin, Mac-2BP/90K displays an exclusive tumor progression associated expression pattern. However, in contrast to the stromal expression of Endosialin, Mac-2BP/90K is strictly expressed by the tumor cell compartment. The mutually exclusive expression pattern suggests a repulsive interaction between Endosialin and Mac-2BP/90K which was confirmed in cellular experiments. Ongoing experiments are aimed at mechanistically studying the role of the Endosialin - Mac-2BP/90K interaction in controlling the crosstalk between the tumor cell and the stromal cell compartments during tumor progression and metastasis.

Abstract
Syndecan-1 forms complexes with growth factors and their cognate receptors in the cell membrane. We have previously reported a tubulin-mediated translocation of syndecan-1 to the nucleus. The transport route and functional significance of nuclear syndecan-1 is still incompletely understood. Here we investigate the sub-cellular distribution of syndecan-1, FGF-2, FGFR-1 and heparanase in malignant mesenchymal tumor cells, and explore the possibility of their coordinated translocation to the nucleus. To elucidate a structural requirement for this nuclear transport, we have transfected cells with a syndecan-1/EGFP construct or with a short truncated version containing only the tubulin binding RMKKK sequence. The sub-cellular distribution of the EGFP fusion proteins was monitored by fluorescence microscopy. Our data indicate that syndecan-1, FGF-2 and heparanase co-localize in the nucleus, whereas FGFR-1 is enriched mainly in the perinuclear area. Overexpression of syndecan-1 results in increased nuclear accumulation of FGF-2, demonstrating the functional importance of syndecan-1 for this nuclear transport. Interestingly, exogenously added FGF-2 does not follow the route taken by endogenous FGF-2. Furthermore, we prove that the RMKKK sequence of syndecan-1 is necessary and sufficient for nuclear translocation, acting as a nuclear localization signal, and the Arginine residue is vital for this localization. We conclude that syndecan-1 and FGF-2, but not FGFR-1 share a common transport route and co-localize with heparanase in the nucleus, and this transport is mediated by the RMKKK motif in syndecan-1. Our study opens a new perspective in the proteoglycan field and provides more evidence of nuclear interactions of syndecan-1.

Abstract
BACKGROUND Clostridium septicum infections are rare but often fatal. They are known to be associated with a compromised immune system, e.g. with hematologic malignancies. CASE REPORT We report on a spontaneous, non-traumatic C. septicum infection in a patient with non-Hodgkin's lymphoma undergoing irradiation due to abdominal bulk. Irradiation was delivered in daily fractions of 1.8 Gy. After 7 fractions, the patient suddenly developed severe pain in the lower leg. Clinical examination showed no pathological findings. However, a rapid progression of symptoms with motoric and sensoric deficits progressed rapidly within hours. Sizzling noise and gas entrainment were detectable about 9 h after the first symptoms. Despite immediate surgical treatment, and in the end amputation, the patient died 14 h later of septic shock. Histopathology showed gas gangrene in the leg tissue, with hemorrhagic muscular necrosis and enclosed gas vesicles. C. septicum was identified as causative organism. CONCLUSIONS Irradiation as well as chemotherapy may have enhanced the risk by immunosuppression and induction of mucosal damage. Earlier antibiotic treatment might have slowed down the clinical course and thus given more time for correct diagnosis and treatment.

Abstract
PURPOSE Head and neck squamous cell carcinomas (HNSCC) are characterized by a poor prognosis due to aggressive, recurrent tumor growth. Expression of the extracellular matrix-degrading enzyme heparanase was associated with poorer prognosis in several cancers. We analyzed the presence of heparanase in HNSCC tissues and tumor cells and its potential prognostic significance. EXPERIMENTAL DESIGN We analyzed the expression of the active form of heparanase in HNSCC tissues in corresponding tumor cell cultures and after xenotransplantation of tumor cell cultures into NOD/Scid mice by immunohistochemistry, Western blot analysis, and reverse transcription-PCR in altogether 25 patients and did a comparison with clinicopathologic data of the patients. RESULTS Heparanase expression in situ was detected in all tumor biopsies in the tumor stroma and in tumor cells from 13 of 19 primary tumors and 9 of 12 lymph node metastases. Heparanase was localized in disseminated tumor cells, in tumor cell clusters invading adjacent stromal tissues, and in tumor cells at the tumor invasion front. Lymph node metastases expressed higher levels of heparanase compared with corresponding primary tumors. In contrast to a heterogeneous expression pattern in tumor tissues, all corresponding HNSCC tumor cell cultures showed a rather homogeneous heparanase expression on the mRNA and protein levels. Comparison of heparanase expression in situ and in corresponding tumor cell cultures in vitro or after xenotransplantation into NOD/Scid mice revealed that heparanase expression was regulated in vivo. Lack of heparanase in tumor cells from primary tumors or lymph node metastases was correlated with prolonged disease-free survival and overall survival. CONCLUSION Heparanase expression seems to be involved in the invasiveness and aggressiveness of HNSCC.
