Abstract: The present invention is based on the finding that antibodies raised against a fragment of PAR1-released peptide may be used to detect in a bodily fluid sample from a subject a marker associated with cancer state, if said subject has cancer.

Abstract: The present invention relates to nucleic acid molecules, vectors, compositions, and methods useful for modulating protease-activated receptor 1 gene expression via RNA interference. In particular, the instant invention features small interfering RNA (siRNA) and short hairpin RNA (shRNA) molecules and methods for modulating the expression of protease-activated receptor 1 gene.

Abstract: A method for treating metastatic tumor cells of a subject is disclosed. The method comprises administrating to the subject an antisense molecule comprising a nucleotide sequence which is complementary to an RNA sequence of a protease activated receptor (PAR) protein, or an antibody molecule capable of binding to a PAR protein. A method is also described for the treatment of disorders involving the implantation of a placenta in a female subject comprising administrating to the subject the antisense molecule. Also disclosed is the antisense molecule and a pharmaceutical composition comprising it.

Abstract: Pharmaceutical compositions for the treatment of a decrease in the levels of protease activated receptor (PAR) mRNA caused by a lack or decrease of oxygen level and/or a lack or decrease of blood flow including pharmaceutically acceptable carriers and activators of PAR are provided. Methods for prevention of a decrease in the levels of protease-activated receptor PAR mRNA caused by lack or decrease in the oxygen level and/or lack or decrease in blood flow are also provided.

Abstract: The present invention concerns a method for evaluating the metastatic tendency of tumor cells by determining the level of expression (mRNA level) of the gene coding for the thrombin receptor (ThR) or by determining the level of the thrombin receptor present on the membranes or within the tumor cells. A high level of either of the above indicates a high metastatic tendency, a low level indicates a low metastatic tendency and an intermediate level indicates a moderate metastatic tendency. The present invention further concerns a kit for use in the above method.

Abstract: The present invention concerns novel pharmaceutical compositions for the atment of cancer, either by inhibition of the tumor metastatic tendency or alternatively by inhibiting formation of new blood vessels (angiogenesis) and thus depriving the tumor from its blood source. The active compound in the pharmaceutical compositions of the invention is a fragment of the Thrombin B-chain comprising the sequence Arg-Gly-Asp in an exposed orientation, or modified thrombin in which the naturally cryptic Arg-Gly-Asp sequence has been modified so that it is in an exposed orientation.
