BACKGROUND Aberrant promoter hypermethylation of cancer-associated genes occurs frequently during carcinogenesis and may serve as a cancer biomarker. In this study we aimed at defining a quantitative gene promoter methylation panel that might identify the most prevalent types of renal cell tumors. METHODS A panel of 18 gene promoters was assessed by(More)
BACKGROUND A defective mitotic checkpoint has been proposed to contribute to chromosomal instability (CIN). We have previously shown that expression changes of the mitotic arrest deficiency (MAD) gene family plays a role in renal cell cancer (RCC) characterized by numerical chromosomal changes, namely papillary and chromophobe carcinomas, but nothing is(More)
The T lineage glycoprotein CD6 is generally considered to be a costimulator of T-cell activation. Here, we demonstrate that CD6 significantly reduces early and late T-cell responses upon superantigen stimulation or TCR triggering by Abs. Measuring calcium mobilization in single cells responding to superantigen, we found that human T cells expressing rat CD6(More)
The transmembrane surface glycoprotein CD6 was one of the first antigens identified on T lymphocytes. The recognition of its involvement in T-cell signaling processes heralds the potential of CD6 as a target for therapy in a number of pathologies associated with imbalances in T-cell function. Its tissue distribution, cellular expression, and overall(More)
