Patent ID: 7364845

Claim:
A method of prognosing cancer in a mammal, comprising the step of assessing whether the expression of a nucleic acid molecule encoding a polypeptide having the function of a human K + eag ion channel is higher in cells of the mammal tested relative to control expression in normal cells, wherein the nucleic acid molecule comprises a nucleic acid sequence selected from the group consisting of: (a) a nucleic acid sequence encoding the polypeptide having the amino acid sequence SEQ ID NO: 3; (b) the nucleic acid sequence SEQ ID NO: 13; (c) a nucleic acid sequence that hybridizes to the complementary strand of the nucleic acid sequence of (a) or (b) at 4×SSC at 65° C. or at 4×SSC at 42° C. in 50% formamide, followed by washing in 0.1×SSC at 65° C. for one hour; and (d) a nucleic acid sequence that is degenerate to the nucleic acid sequence of (c).
