Until now it was thought that the risk of genomic stability was avoided for the most part, because the first step of the SHM process only happened in antibody genes. But this study shows that AID acts on many other genes in B cells, including genes associated with lymphatic cancer and other malignancies. – And then we had another surprise, said Schatz. Most of these non-antibody genes do not accumulate mutations because the repair, for whatever reason, is not accurate, sloppy. .

The lymphatic system consists of B cells fight infections. Schatz and his colleagues examined the somatic hypermutation process, the random mutations resulting in B cells ‘ antibody genes more effectively in order to fight infections.Marshall Anderson , a professor of Crab and cellular biology division UC is to principal investigator on the GELCC whose UC portion will known as a Family Lung Cancer Study. Susan Pinney, years in the Division of the environment and health , is a co-investigator. The study’s first author being Christopher Amos Professor and an epidemiologist at University of Texas MD Anderson in Houston. ‘The study shows a sharp Gen-environment interaction between the region of Chromosome 6q and smoking,’said Anderson UC. ‘People with this susceptibility locus can be lung at very slightly smoking to develop.’.

To family members that carry this genetic variant, the risk of for lung cancer light and heavy duty light and heavy smoking , the researchers say, adding that even non – smokers, second-hand cigarette smoke exposed, and a family history who for early recognition of for early detection of lung cancer.
