    Es ist Konsens in der Klimaforschungsgemeinschaft, dass der globale Klimawandel mit großer Wahrscheinlichkeit mit einer erhöhten HĂ€ufigkeit von witterungsbedingten Naturkatastrophen einhergeht [IPCC, 2011]. Grundlage fĂŒr diese Schlussfolgerung sind im Wesentlichen die Ergebnisse globaler und regionaler Klimasimulationen. Neben WindstĂŒrmen sind insbesondere Auftreten und HĂ€ufigkeit von hydrometeorologischen Extremereignissen wie z. B. Starkregen oder DĂŒrre ursĂ€chlich fĂŒr korrespondierende Naturkatastrophen, die fĂŒr den Katastrophenschutz relevant sind. So sind die Anzahl von UmwelteinsĂ€tzen der Feuerwehr im Nachgang von Extremereignissen wie Starkregen oder Hagel [Geier, 2009] sowie die Zahl der wetterbedingten EinsĂ€tze des Technischen Hilfswerks in den vergangenen Jahren gestiegen [Strotmann, 2011]. Dieser Trend wird von einer Befragung der im Katastrophenschutz eingebundenen Organisationen bestĂ€tigt, nach deren Ergebnissen neben Sturmereignissen vor allem Hochwasser vermehrt EinsĂ€tze nach sich ziehen

    Galectin-1 and Its Involvement in Hepatocellular Carcinoma Aggressiveness

    Hepatocellular carcinoma is one of the most common cancers worldwide. Despite several efforts to elucidate hepatocellular carcinoma molecular pathogenesis, it is still not fully understood. To acquire further insights into the molecular mechanisms of hepatocellular carcinoma, we performed a systematic functional genomic approach on human HuH-7 and JHH-6 cells. The subsequent analysis of the differentially expressed genes in human specimens revealed a molecular signature of 11 genes from which we selected the LGALS1 gene, which was overexpressed in hepatocellular carcinoma. The expression analysis in humans of Galectin-1 (Gal-1), the protein encoded by LGALS1, showed a Gal-1 preferential accumulation in the stromal tissue around hepatocellular carcinoma tumors. Moreover, a significant association between increased expression of Gal-1 in hepatocellular carcinoma and the presence of metastasis was observed. Interestingly, Gal-1 overexpression resulted in an increase of cell migration and invasion. In conclusion, this study provides a portfolio of targets useful for future investigations into molecular marker–discovery studies on a large number of patients and functional assays. In addition, our data provide evidence that Gal-1 plays a role in hepatocellular carcinoma cell migration and invasion, and we suggest that further studies should be conducted to fully establish the role of Gal-1 in hepatocellular carcinoma pathogenesis and evaluate Gal-1 as a potential molecular therapeutic target
