摘要:
An object of the present invention is to develop and provide a lung cancer differential marker with which lung cancer can be diagnosed conveniently and highly sensitively without depending only on increase or decrease in protein expression level between cancer patients and healthy persons. Another object of the present invention is to develop and provide a glycan marker capable of distinguishing histological types of lung cancer. Of serum glycoproteins, glycopeptide and glycoprotein groups whose glycan structures were altered specifically in lung cancer cell culture supernatants were identified, and they are provided as lung cancer differential markers.
摘要:
The present invention is directed to developing a glycan markers capable of detecting a hepatic disease, and more specifically to developing a glycan marker indicating a hepatic disease-state. Furthermore, the present invention is also directed to developing a glycan marker capable of distinguishing hepatic disease-states with the progress of hepatocarcinoma. The present inventors identified, among the serum glycoproteins, glycopeptides and glycoproteins in which a glycan structure specifically changes due to a hepatic diseases including hepatocarcinoma and provide these as novel glycan markers (glycopeptide and glycoprotein) specific to hepatic disease-states.
摘要:
An enzyme having an activity of transferring N-acetylglucosamine to the non-reducing end of a Galβ1-4Glc or Galβ1-4GlcNAc-group via a β-1,3 bond; a nucleic acid encoding the same; and a method of diagnosing cancer and/or tumor, in particular, digestive cancer and/or tumor using the expression dose of a gene of the above enzyme as an indication. A gene of a novel enzyme having an activity of transferring N-acetylglucosamine to the non-reducing end of a Galβ1-4Glc or Galβ1-4GlcNAc-group via a β-1,3 bond is cloned from human stomach cells and its base sequence is determined. Then this enzyme is expressed. Since this enzyme is scarcely or never produced in cancer and/or tumor, in particular, digestive cancer and/or tumor cells, cancer and/or tumor can be diagnosed with the use of the expression of the enzyme gene as an indication.
摘要:
The present invention provides an antibody capable of specifically recognizing and detecting the highly specific cancer marker with respect to the epithelial ovarian cancer, or a fragment of the antibody. The present invention provides an anti-²1,3-N-acetylglucosaminyltransferase 3 antibody for diagnosis of epithelial ovarian cancer, i.e., an antibody for detection of a glycosyltransferase ²1,3-N-acetylglucosaminyltransferase 3 as an epithelial ovarian cancer marker. The antibody recognizes, as an epitope, a part of a polypeptide of the enzyme consisting of the amino acid sequence represented by SEQ ID NO: 1.
摘要:
A cancer marker nucleic acid which is hybridizable with the base sequence represented by SEQ ID NO:1 or a base sequence complementary thereto under stringent conditions; and a method of testing canceration wherein a biological sample is judged as cancerous in the case of showing a significantly higher transcriptional level of the above nucleic acid than that in a normal biological sample employed as a control. A β1,3-N-acetyl-D-glucosamine transferase protein having an activity of transferring N-acetyl-D-glucosamine from a donor substrate to a receptor substrate via a β1,3-bond.
摘要:
An N-acetyl-D-galactosamine transferase protein characterized by transferring N-acetyl-D-galactosamine to N-acetyl-D-glucosamine via a beta1,3-bond. It preferably has an amino sequence represented by SEQ ID NO:2 or 4. A method of examining canceration by using a nucleic acid for assaying which is hybridizable under stringent conditions with a base sequence represented by SEQ ID NO:1 or 3 or a base sequence being complementary to at least one of these base sequences.
