Differentially expressed tumor-specific polypeptides for use in cancer diagnosis and therapy

摘要

The invention relates to agents and methods for the diagnosis, prognosis and treatment of cancer. Specifically, the invention relates to the use of nucleic and amino acid sequences encoding transmembrane superfamily member 6 (TM4SF6), synaptophysin-like protein (SYPL), stomatin-like 2 (STOML2), Ras-related GTP-binding protein RAGA), nucleotide-sensitive chloride channel 1A (CLNS1A), prion protein (p27-30) (PRNP), guanine nucleotide binding protein beta 2-like 1 (GNB2L1), guanine nucleotide binding protein 4 (GNG4), integral membrane protein 2B (ITM2B), integral membrane protein 1 (ITM1), transmembrane 9 superfamily member 2 (TM9SF2), opiate receptor-like 1 protein (OPRL1), low density lipoprotein receptor-related protein 4 (LRP4), human glomerular epithelial protein 1 (GLEPP1), toll-like receptor 3 (TLR3), and/or zona pellucida glycoprotein 3A (ZP3) for the diagnosis of both early and late stage non-steroid specific cancers, cancer prognosis, as well as screening for therapeutic agents that regulate the gene expression and/or biological activity of said proteins. This invention further relates to the biological technologies designed to inhibit the gene expression and/or biological activity of said proteins including using agents identified in screening assays described herein, vector delivery of antisense polynucleotide sequences, and antibody targeting of said proteins. In specific embodiments, the proteins are of human origin.
