Geng et al. explored the expression of a transcript of the Igα1 gene SNC73 and its related genes (RAG1, RAG2, and 3 transcription factors) in cancer cells, including LOVO (colorectal cancer), SW480 (colorectal cancer), HeLa (cervical cancer), SMC7721 (liver cancer), and Bcap-37 (breast cancer). The gene discussed is RAG1; the disease is breast cancer.
