Frequent nonrandom activation of germ-line genes in human cancer.
Abstract The growing class of cancer/germ-line genes is characterized by a unique expression pattern with transcription restricted to germ cells and cancer cells. It is not known which fraction of germ-line genes is ectopically activated in tumor cells and whether this fraction displays common features as compared with strictly germ-line genes remaining silent in cancer. Using an unbiased genome-wide scanning approach, representative samples of both cancer/germ-line genes as well as strictly germ-line-specific genes were determined. Comparative analysis disclosed highly significant diametric characteristics for these two categories of genes with regard to sex specificity, developmental stag…
A novel tumour associated leucine zipper protein targeting to sites of gene transcription and splicing
We describe here the definition and characterization of antigen CT-8/HOM-TES-85 encoded by a previously unknown gene and identified by serological expression screening using antibodies from a seminoma patient. Intriguingly, the leucine zipper region of CT-8/HOM-TES-85 shows an atypical amphipathy with clusters of hydrophobic residues that is exclusively shared by the N-myc proto-oncogene. CT-8/HOM-TES-85 gene is tightly silenced in normal tissues except for testis. However, it is frequently activated in human neoplasms of different types including lung cancer, ovarian cancer, melanoma and glioma. Endogenous as well as heterogeneously expressed CT-8/HOM-TES-85 targets predominantly to the nu…
