Hypoxia induces adhesion molecules on cancer cells: A missing link between Warburg effect and induction of selectin-ligand carbohydrates.

ABSTRACT: Cancer cells undergo distinct metabolic changes to cope with their hypoxic environment. These changes are achieved at least partly by the action of transcriptional factors called hypoxia-inducible factors (HIFs). We investigated gene expression in cultured human colon cancer cells induced by hypoxic conditions with special reference to cell-adhesion molecules and carbohydrate determinants having cell-adhesive activity by using DNA-microarray and RT-PCR techniques. Hypoxic culture of colon cancer cells induced a marked increase in expression of selectin ligands, the sialyl Lewis x and sialyl Lewis a determinants at the cell surface, which led to a definite increase in cancer cell adhesion to endothelial E-selectin. The transcription of genes for fucosyltransferase VII (FUT7), sialyltransferase ST3Gal-I (ST3O), and UDP-galactose transporter-1 (UGT1), which are all known to be involved in the synthesis of the carbohydrate ligands for E-selectin, was significantly induced in cancer cells by hypoxic culture. In addition, a remarkable induction was detected in the genes for syndecan-4 (SDC4) and alpha5-integrin (ITGA5), the cell-adhesion molecules involved in the enhanced adhesion of cancer cells to fibronectin. The transcriptional induction by hypoxia was reproduced in the luciferase-reporter assays for these genes, which were significantly suppressed by the co-transfection of a dominant-negative form of HIF. These results indicate that the metabolic shifts of cancer cells partly mediated by HIFs significantly enhance their adhesion to vascular endothelial cells, through both selectin- and integrin-mediated pathways, and suggest that this enhancement further facilitates hematogenous metastasis of cancers and tumor angiogenesis.

Project description:Cell surface molecular adhesions govern many important physiological processes and are used to identify cells for analysis and purifications. But most effective cell adhesion separation technologies use labels or long-term attachments in their application. While label-free separation microsystems typically separate cells by size, stiffness, and shape, they often do not provide sufficient specificity to cell type that can be obtained from molecular expression. We demonstrate a label-free microfluidic approach capable of high throughput separation of cells based upon surface molecule adhesion. Cells are flowed through a microchannel designed with angled ridges at the top of the channel and coated with adhesive ligands specific to target cell receptors. The ridges slightly compress passing cells such that adhesive contact can be made with sufficient surface area without unduly affecting cell trajectories because of cell stiffness. Thus, sorting is sensitive to cell adhesion but not to stiffness or cell size. The enforced interactions between the cells and the ridges ensure that a high flow rate can be used without lift forces quenching adhesion. As a proof of principle of the method, we separate both Jurkat and HL60 cell lines based on their differential expression of PSGL-1 ligand by using a ridged channel coated with P selectin. We demonstrate 26-fold and 3.8-fold enrichment of PSGL-1 positive and 4.4-fold and 3.2-fold enrichment of PSGL-1 negative Jurkat and HL60 cells, respectively. Increasing the number of outlets to five allows for greater resolution in PSGL-1 selection resulting in fractionation of a single cell type into subpopulations of cells with high, moderate, and low PSGL-1 expression. The cells can flow at a rate of up to 0.2 m/s, which corresponds to 0.045 million cells per minute at the designed geometry, which is over 2 orders of magnitude higher than previous adhesive-based sorting approaches. Because of the short interaction time of the cells with the adhesive surfaces, the sorting method does not further activate the cells due to molecular binding. Such an approach may find use in label-free selection of cells for a highly expressed molecular phenotype.

Project description:Background and aimsThe species-poor and little-studied genus Verhuellia has often been treated as a synonym of the genus Peperomia, downplaying its significance in the relationships and evolutionary aspects in Piperaceae and Piperales. The lack of knowledge concerning Verhuellia is largely due to its restricted distribution, poorly known collection localities, limited availability in herbaria and absence in botanical gardens and lack of material suitable for molecular phylogenetic studies until recently. Because Verhuellia has some of the most reduced flowers in Piperales, the reconstruction of floral evolution which shows strong trends towards reduction in all lineages needs to be revised.MethodsVerhuellia is included in a molecular phylogenetic analysis of Piperales (trnT-trnL-trnF and trnK/matK), based on nearly 6000 aligned characters and more than 1400 potentially parsimony-informative sites which were partly generated for the present study. Character states for stamen and carpel number are mapped on the combined molecular tree to reconstruct the ancestral states.Key resultsThe genus Peperomia is generally considered to have the most reduced flowers in Piperales but this study shows that this is only partially true. Verhuellia, with almost equally reduced flowers, is not part of or sister to Peperomia as expected, but is revealed as sister to all other Piperaceae in all analyses, putting character evolution in this family and in the perianthless Piperales in a different light. A robust phylogenetic analysis including all relevant taxa is presented as a framework for inferring patterns and processes of evolution in Piperales and Piperaceae.ConclusionsVerhuellia is a further example of how a molecular phylogenetic study can elucidate the relationships of an unplaced taxon. When more material becomes available, it will be possible to investigate character evolution in Piperales more thoroughly and to answer some evolutionary questions concerning Piperaceae.

Project description:The origin and deep evolution of retroviruses remain largely unclear. It has been proposed that retroviruses might have originated from a Ty3/Gypsy retrotransposon, but all known Ty3/Gypsy retrotransposons are only distantly related to retroviruses. Retroviruses and some plant Athila/Tat elements (within Ty3/Gypsy retrotransposons) independently evolved a dual RNase H domain and an env/env-like gene. Here, we reported the discovery of a novel lineage of retrotransposons, designated Odin retrotransposons, in the genomes of eight sea anemones (order Actinaria) within the Cnidaria phylum. Odin retrotransposons exhibited unique genome features, encoding a dual RNase H domain (like retroviruses) but no env gene (like most Ty3/Gypsy retrotransposons). Phylogenetic analyses based on reverse transcriptase showed that Odin retrotransposons formed a sister group to lokiretroviruses, and lokiretroviruses and Odin retrotransposons together were sister to canonical retroviruses. Moreover, phylogenetic analyses based on RNase H and integrase also supported the hypothesis that Odin retrotransposons were sisters to lokiretroviruses. Lokiretroviruses and canonical retroviruses did not form a monophyletic group, indicating that lokiretroviruses and canonical retroviruses might represent two distinct virus families. Taken together, the discovery of Odin retrotransposons narrowed down the evolutionary gaps between retrotransposons and canonical retroviruses and lokiretroviruses. IMPORTANCE The origin of retroviruses remains largely unclear. In this study, we discovered a novel retrotransposon lineage, Odin retrotransposons, within the genomes of sea anemones (order Actinaria). In contrast to retroviruses and most retrotransposons, Odin retrotransposons encode a dual RNase H domain but no env gene. Phylogenetic analyses showed that Odin retrotransposons were sisters to lokiretroviruses, and lokiretroviruses and Odin retrotransposons were sisters to retroviruses, establishing an evolutionary framework to decipher the origin of retroviruses (canonical retroviruses and lokiretroviruses). Our results provided insights into the diversity and deep evolution of LTR retrotransposons closely related to retroviruses.
