A recent study on lung adenocarcinoma showed that radioactive 125I seed implantation therapy inhibited proliferation of tumor cells, retarded tumor growth, and promoted apoptosis in human lung adenocarcinoma A549 cells by upregulating p21 and Caspase‐9 protein expression, and downregulating survivin and livin protein expression.22 Here, BIRC7 is linked to lung adenocarcinoma.
