Stimulation by insulin of protein synthesis in cultured chick embryo fibroblasts.

abstract：:DNA mismatch repair (MMR) is an important replication error avoidance mechanism that prevents mutation. The association of defective MMR with familial and sporadic gastrointestinal and endometrial cancer has been acknowledged for some years. More recently, it has become apparent that MMR defects are common in acute my...
