Compositions for diagnosis and treatment of pancreatic cancer, prostate cancer, liver cancer, ovarian cancer, lung cancer, colorectal cancer, kidney cancer, non-erythroid hematologic cancer or mesothelioma cancer using CaSm

摘要

A nucleic acid composition encoding CaSm (cancer-associated Sm-like) that is highly expressed in cancer tissues and cell lines, especially pancreatic cancer. The full length cDNA of CaSm encodes a protein of 133 amino acids. CaSm contains the two Sm motifs found in the common snRNP proteins, with the greatest homology to the Sm G protein (60 % similarity). Further described are CaSm peptides, fusion proteins, host cell expression systems, antibodies to CaSm, antisense CaSm molecules, and compounds that modulate CaSm gene expression or CaSm activity. Antisense CaSm RNA is able to alter the transformed phenotype of pancreatic cancer cells by reducing their ability to form large colonies in soft agar when compared to untransfected cells.
