Methylation of arginine residues has been implicated in many cellular activities like mRNA splicing, transcription regulation, signal transduction and protein-protein interactions. Protein arginine methyltransferases are the enzymes responsible for this modification in living cells. The most commonly used methyltransferase in man is protein arginine methyltransferase 1 (PRMT1).

Background: In this study, the possible relation of the expression pattern of arginine methyltransferase 1 and colon cancer progression is investigated.

Materials And Methods: Colon cancer samples as well as normal colon samples were used to define the arginine methyltransferase 1 expression by RT-PCR. The results were associated with clinical and histological parameters of the tissues.

SR (serine-arginine) proteins are essential pre-mRNA splicing factors. Several SR proteins have been characterized in humans, among them SR-A1. It has been demonstrated by members of our group that the SR-A1 gene is constitutively expressed in most of the human tissues, while its transcription is increased in breast carcinoma cell lines.

Apoptosis is an active process regulated by a variety of genes. Recently, the molecular cloning, physical mapping and expression analysis of a novel gene of the Bcl-2 family, BCL2L12, was reported. Expression analysis of the BCL2L12 gene in breast cancer confirmed an association of BCL2L12 with favorable prognosis of patients.
