PURPOSE The melanoma-associated antigens (MAGEs) are tumor-specific antigens recognized by cytotoxic T lymphocytes. In this study, expression of MAGE family A members was evaluated during the development of esophageal adenocarcinoma (EA) as potential targets for immunotherapy. EXPERIMENTAL DESIGN MAGE-A mRNA expression was evaluated in 46 samples including Barrett's metaplasia (BM), dysplasia...

PURPOSE The monoclonal antibody Ki-A10 (IgG1) generated after immunization of mice with Hodgkin's lymphoma cell line L428 detects a nuclear antigen in human tissues with a restricted distribution pattern similar to cancer/testis antigens. The aim of this study was to characterize the antigen and to determine the expression profile in Hodgkin's lymphoma. EXPERIMENTAL DESIGN The half-life and p...

HLA class I antigen distribution of Sikh population from Punjab is presented. A total of 404 individual of Sikh community who were either donors for renal transplant recipients or staff in PGIMER Chandigarh were selected. HLA class I antigens (A and B) were identified using the standard National Institute of Health two stage micro lymphocytotoxicity assay. The phenotypic frequencies of HLA-A10 ...

The U-A10 cell line, a doxorubicin-selected variant of human U-937 myeloid leukemia cells, exhibits a redistribution of anthracyclines into a expanded vesicular compartment. The acidic nature of this compartment was confirmed by vital staining with a pH sensitive dye, LysoSensor yellow/blue DND-160. Identification of the vesicular compartment was performed by immunofluorescence analysis. Staini...

An aerobic, pink-pigmented, budding and rosette-forming bacterium was isolated from an acidic Sphagnum peat bog and designated strain A10(T). The 16S rRNA gene sequence analysis showed that strain A10(T) was a member of the order Planctomycetales and belonged to a phylogenetic lineage defined by the genus Gemmata, with 90 % sequence similarity to that of Gemmata obscuriglobus, the only taxonomi...

Serum C2 activity was measured in 135 individuals drawn from a panel of 418 tissue-typed blood donors. The study group included all donors with HLA antigens A10 and B18. Heterozygote C2 deficiency (C2Dhet) was defined by reference to the range of C2 activity in previously studied obligate heterozygotes. Five donors were C2Dhet. Family studies confirmed that C2Dhet was associated in all instance...

Drug-resistant sublines of the human U-937 myeloid leukemia cell line were selected in doxorubicin concentrations of 10, 40, and 200 ng/mL (designated U-A10, U-A40, and U-A200, respectively). Northern blot analysis showed overexpression of the multidrug resistance-associated protein (MRP) gene, but not MDR1, in U-A10 cells as compared with parental U-937 cells. Prolonged passage of U-A10 cells ...
