Abstract

PROBLEMProvided is a prevention/treatment means for cancer, by controlling expression/function of a target molecule different from a conventional one, as a novel method in the molecularly-targeted treatment method for a cancer. In addition, provided is a screening means for a substance having prevention/treatment activity for cancer, using the above target molecule.SOLUTIONAccording to one aspect of the present invention, there is provided a cell adhesion inhibitor for a cancer cell, containing an antibody to a protein containing the same or substantially the same amino acid sequence as the amino acid sequence, represented by SEQ ID No: 2 or represented by SEQ ID No: 4 or represented by SEQ ID No: 6 or a partial peptide thereof. According to another aspect of the present invention, there is provided a cell adhesion inhibitor for a cancer cell, containing an antisense polynucleotide containing a complementary or substantially complementary base sequence to a base sequence of a polynucleotide encoding a protein containing the same or substantially the same amino acid sequence as the amino acid sequence, represented by SEQ ID No: 2 or represented by SEQ ID No: 4 or represented by SEQ ID No: 6 or apart thereof. According to further another aspect of the present invention, there is provided a cell adhesion inhibitor for a cancer cell, containing a substance to inhibit expression and/or activity of protein containing the same or substantially the same amino acid sequence as the amino acid sequence represented by SEQ ID No: 2 or represented by SEQ ID No: 4 or represented by SEQ ID No: 6.
