| Popis: | Breast cancer is the most common malignant tumor in women and one of the three most common cancers worldwide. It is a life-threatening disease among women and the leading cause of death among women. New drugs or new drug translations and laboratory clinical studies are ongoing. A new antitumor protein (PNAP) purified from edible fungus Pholiota nameko has potential for treating breast cancer. We have previously found that PNAP exhibits anti-proliferative and apoptosis-inducing activities in a human breast cancer cell line (MCF-7). In this study, we constructed a BALB/c mouse model of MCF-7 tumor xenografts. In vivo experiments show that PNAP can effectively inhibit the malignant proliferation of MCF-7 solid tumors. This is because PNAP can successfully activate the death receptor pathway and mitochondrial apoptosis pathway of MCF-7 tumor cells in vivo, and induce tumor cells to wither. It is estimated that PNAP may also have an immunoregulatory ability to indirectly inhibit malignant proliferation of tumors. We also found that PNAP may also have the immunomodulatory ability to indirectly inhibit the malignant proliferation of tumors, which can shift the balance of Th1/Th2 to Th1 and eventually inhibit the growth of tumors. The study reveals a new therapeutic approach for breast cancer patient. |
