Novel N-acetylglucosaminyltransferase, nucleic acid coding for the same, and uses thereof for diagnosis of cancer or tumor

A method for diagnosis of a cancer and/or tumor, comprising:

• hybridizing a nucleic acid to an mRNA transcribed from a gene comprising a sequence encoding a protein comprising an amino acid sequence according to SEQ ID NO:3 or to a cDNA generated by transcription of said mRNA, and
• measuring the hybridized nucleic acid, so as to measure an expression amount of the gene of said protein, whereby an expression amount of the gene is indicative of the presence of cancer and/or a tumor.

A method for diagnosis of a cancer and/or tumor, comprising:

• amplifying a nucleic acid using as primers a pair of nucleic acids for measurement of nucleic acid, and using as a template an mRNA transcribed from a gene encoding a protein comprising an amino acid sequence according to SEQ ID NO:3 or a cDNA generated by transcribing said mRNA to produce an amplification product, and
• measuring the amplification product, to determine an expression amount of the gene encoding said protein, whereby an expression amount of the gene is indicative of the presence of cancer and/or a tumor.
