TARS1 and breast cancer: Previous research has shown that TARS1 is secreted in inflammatory states and stimulates endothelial cell migration and angiogenesis, and given the hypermetabolic state of tumors and their reliance on neovascularisation, researchers believe this is one of the reasons why it promotes the development of breast cancer (12).Breast cancer cells exhibit a swift metabolism and abbreviated proliferation cycle in contrast to normal breast cells, resulting in more robust protein synthesis, particularly during cellular metamorphosis and migration.
