Abstract
Metallopanstimulin-1 (MPS-1), belonging to the ribosomal protein S27E family, is ubiquitously expressed in all normal tissues except the brain and placenta. In addition, MPS-1 is highly expressed in malignant tumors and cells. MPS-1 as a tumor marker or tumor-associated antigen has been extensively studied in head and neck cancer and breast cancer. MPS-1 is highly expressed in gastric cancer. Knockdown of MPS-1 expression inhibits the growth of cancer cells both in vitro and in vivo and induces spontaneous apoptosis of gastric cancer cells by repressing the NF-κB signaling pathway. In addition, MPS-1 is also highly expressed in colonic cancer and has a close relationship with the degree of malignancy and prognosis. Therefore, MPS-1 may be a novel potential therapeutic target for cancers.
