摘要:
The present invention provides pharmaceutical preparations for anti-inflammation, anti-infection, inhibition of cancer metastasis etc., foods such as dairy products etc., and a method for improving proteins, as well as a method for diagnosis of inflammatory diseases and cancer malignancy. According to the present invention, there can be provided a polypeptide having poly-N-acetyllactosamine sugar chains synthesis-related activity, a process for producing the polypeptide, DNA coding for the polypeptide, a process for producing the DNA, a recombinant vector having the DNA integrated therein, a transformant carrying the recombinant vector, an antibody recognizing the polypeptide, a process for producing poly-N-acetyllactosamine sugar chains by use of the DNA or the polypeptide, diagnosis and treatment of diseases such as inflammations, cancers etc. by use of the DNA, the polypeptide or the antibody, determination and immunostaining of the polypeptide of the present invention by use of the antibody, a method for screening a compound varying the expression of a gene coding for the polypeptide, and a method for screening a substance varying the activity of the polypeptide.
摘要:
The invention provides a novel species of α-1,3-fucosyltransferase expressed by a gene cloned from animal cells, a cDNA coding for the α-1,3-fucosyltransferase, a method of detecting, or inhibiting the production of, the α-1,3-fucosyltransferase which involves the use of the cDNA, a recombinant vector containing the DNA as an insert, a cell harboring the recombinant vector, and a method of producing same. The α-1,3-fucosyltransferase of the invention is useful in the production of carbohydrate chains having useful physiological activity, for example sialyl Lewis x, and modifications thereof.
摘要:
A novel DNA whose expression level fluctuates in leukocytes of IgA nephropathy patients in comparison with leukocytes of healthy persons, a process for isolating the DNA, a novel protein encoded by the DNA, an antibody recognizing the protein, methods for detecting the protein and the DNA, and methods of diagnosis and treatment of IgA nephropathy.
摘要:
A novel motilin analog peptide containing leucine instead of the usual 13th amino acid methionine, as in the naturally occurring motilin, is produced by gene recombination techniques in which several or identical genes, each coding for the novel peptide, are joined in series into a vector. The resultant recombinant DNA is introduced into Escherichia coli and the resultant transformant is cultivated. The resulting polymeric peptide can be cleaved to give the desired peptide.
