Abstract
The present invention is directed towards the diagnosis of malignant cancer by detection of the mts-1 mRNA or the mts-1 protein, encoded by the mts-1 gene. The present invention contemplates the use of recombinant mts-1 DNA and antibodies directed against the mts-1 protein to diagnose the metastatic potential of several types of tumor cells, including, for example, thyroid, epithelial, lung, liver and kidney tumor cells. The present invention is also directed to mammalian cell lines and tumors with high and low metastatic potential which have been developed to serve as useful model systems for in vitro and in vivo anti-metastasis drug screening.
Claims13
A method of diagnosis for determining whether an individual has at least an increased likelihood of metastatic cancer comprising contacting tissue or tissue extracts of a human to be tested with a mouse mts-1 nucleic acid probe, for a time and under conditions sufficient to allow hybridization of said probe with mts-1 mRNA expressed in said tissue or tissue extract and detecting said hybridization wherein said mts-1 mRNA is increased in said tissue or tissue extracts at least 10-fold compared to normal tissue or tissue extracts.
A compartmentalized kit for detection of mts-1 mRNA comprising at least one first container adapted to contain a labeled or unlabeled human mts-1 nucleic acid probe consisting of at least one contiguous fragment of the human mts-1 gene of SEQ ID NO:1, wherein said fragment is at least 10 nucleotides in length.
A method of diagnosis for determining whether an individual has at least an increased likelihood of metastatic cancer comprising contacting tissue or tissue extracts of a human to be tested with a human mts-1 nucleic acid probe, for a time and under conditions sufficient to allow hybridization of said probe with mts-1 mRNA expressed in said tissue or tissue extract and detecting said hybridization wherein said mts-1 mRNA is increased in said tissue or tissue extracts at least 10-fold compared to normal tissue or tissue extracts.
A method of diagnosis for determining whether an individual has at least an increased likelihood of metastatic cancer comprising contacting tissue or tissue extracts of a human to be tested with a rat mts-1 nucleic acid probe, for a time and under conditions sufficient to allow hybridization of said probe with mts-1 mRNA expressed in said tissue or tissue extract and detecting said hybridization wherein said mts-1 mRNA is increased in said tissue or tissue extracts at least 10-fold compared to normal tissue or tissue extracts.
A compartmentalized kit for detection of mts-1 mRNA comprising at least one first container adapted to contain a labeled or unlabeled human mts-1 nucleic acid probe consisting of at least one contiguous fragment of the human mts-1 gene of SEQ ID NO:3 wherein said fragment is at least 10 nucleotides in length.
