Abstract:
Normal cells differ from malignant tumor cells in the transcription levels of many different genes. Two colorectal tumor cell lines were compared with a normal colorectal cell line by differential display reverse transcription PCR to screen for tumor cell specific differentially transcribed genes. By this strategy the upregulation of a novel gene was detected designated as 'upregulated in colorectal cancer gene-1' (UCC1). The UCC1 gene transcript level is increased in cultured tumor cells and in two out of three analyzed colorectal tumor tissue specimens compared to normal cultured cells and to corresponding normal tissue samples. Remarkably, the UCC1 protein shows significant sequence similarity to the highly divergent piscine glycoproteins termed ependymins which are synthesized by leptomeningeal fibroblasts and secreted into the cerebrospinal fluid.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
