  • Publication number: 20120122727
    Abstract: The invention is in the field of genomics and it provides an in vitro method for predicting whether a compound is genotoxic in vivo. It provides a method that employs the analysis of expression profiles of primary mouse hepatocytes as an in vitro system to discriminate false GTX compounds from true GTX carcinogens. It was found that differential expression of a number of genes could reliably predict whether a compound was a true genotoxic compound.

  • Publication number: 20110229483
    Abstract: Crucial to designing anti-angiogenic and vascular targeting approaches is the identification of specific target molecules. We compared transcriptional profiles of tumor endothelial cells with that of normal resting endothelial cells, normal but angiogenically activated placental endothelial cells, and cultured endothelial cells. Although the majority of transcripts were classified as general angiogenesis markers, we identified 17 genes that show specific overexpression in tumor endothelium. Antibody targeting of four cell-surface expressed or secreted products (vimentin, CD59, HMGB1 and IGFBP7) inhibited angiogenesis in vitro and in vivo. Finally, targeting endothelial vimentin in a mouse tumor model significantly inhibited tumor growth and reduced microvessel density. Our results demonstrate the utility of the identification and subsequent targeting of specific tumor endothelial markers for anticancer therapy.

  • Publication number: 20110230357
    Abstract: The invention relates to a method for the classification of cancer using a specific multi-class tumor classifier comprising specific sets of genes for the interpretation of expression data obtained from tumor samples. More specifically, the method of the present invention provides an accurate, reproducible, robust, objective and easy to perform method for determining the primary site of a Cancer of Unknown Primary site (CUP). For this purpose, the method provides that a classifier parameter is determined by comparing an expression profile of a tumor sample with a template profile representative for a particular primary site of a cancer.

  • Publication number: 20110217380
    Abstract: The invention is in the field of weight management, in particular in the field of weight management by influencing the mechanisms of body-weight regulation. Intact pea protein and intact wheat protein were found to be effective in reducing appetite or inducing or increasing satiety when brought into contact with their receptors in the duodenum. Since it is known that intact proteins hydrolyse in the gastrointestinal tract, intact pea protein and intact wheat protein will not exhibit their satiating effect when ingested in a conventional oral preparation. Therefore, special care should be taken to deliver the intact proteins to the duodenum in order for them to arrive there intact. One object of the invention may therefore be achieved by incorporating the intact protein in an enteric delivery vehicle.
