BACKGROUND The diagnosis of malignant lymphoma (ML) such as non-Hodgkin's lymphoma (NHL) and Hodgkin's lymphoma (HL) was mainly performed by morphological examination and gene analysis. There are only a few serum/plasma biomarkers such as lactate dehydrogenase and soluble interleukin-2 receptor alpha to diagnose ML. The classifications are various, and(More)
PURPOSE Detection of novel tumor-related antigens and autoantibodies will aid in diagnosis of early-stage cancer and in development of more effective immunotherapies. The purpose of this study was to identify novel tumor antigens in an esophageal squamous cell carcinoma (ESCC) cell line (TE-2) and related autoantibodies in sera from patients with ESCC using(More)
Detection of novel tumor-related antigens and autoantibodies in cancer patients is expected to facilitate the diagnosis of early-stage malignant tumor and establish effective new immunotherapies. The purpose of this study was to identify novel tumor antigens in an esophageal squamous cell carcinoma (ESCC) cell line (TE-2) and related autoantibodies in sera(More)
Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder affecting motor neurons. The majority of patients are sporadic cases, while 5-10% of the patients have a family history of ALS (fALS). Mutations in the gene that encodes cytoplasmic Cu/Zn superoxide dismutase (SOD1) have been identified in about 25% of fALS cases. Although the(More)
BACKGROUND Molybdenum cofactor deficiency (resulting in combined deficiencies of the enzymes sulphite oxidase, xanthine dehydrogenase and aldehyde dehydrogenase) and isolated sulphite oxidase deficiency are inherited metabolic diseases which follow an autosomal recessive trait of inheritance. Detection of these diseases in selective screening for inborn(More)
Two-dimensional gel electrophoresis and mass spectrometry were used to make a catalogue of soluble proteins in the human vitreous humor (VH). Fifty-one different proteins were identified on silver-stained two-dimensional (2D) gel patterns with VH proteins obtained from diabetic retinopathy and macular hole. Thirty of these have not been listed in the(More)
Molybdenum cofactor deficiency is a fatal neurological disorder, which follows an autosomal-recessive trait and is characterized by combined deficiency of the enzyme, sulfite oxidase, xanthine dehydrogenase and aldehyde oxidase. Early detection of molybdenum cofactor-deficient patients is essential for their proper care and genetic counseling of families at(More)

Some variant proteins cause diseases, and some diseases result in increases of proteins with abnormally modified structures. The detection, characterization, and estimation of the relative amounts of protein variants and abnormally modified proteins are important for clinical diagnosis and for elucidation of the mechanisms of the pathogenesis of diseases.(More)
While the association of homocystinuria with disease is known for more than four decades, mild hyperhomocysteinemia has been detected more recently as a risk factor for a number of diseases. However, the mechanism which apparently renders (even mild) hyperhomocystenemia harmful is not known. Following reports on N-homocysteinylation of proteins by the(More)
