Question 41.How could we generate more effective anti-metastasis drugs? Question 42.What is the molecular mechanism underlying heterogeneity of cancer cachexia in patients with the same pathologic type? Question 43.Will patients with oligo-metastatic disease be curable by immunotherapy plus stereotactic body radiotherapy? Question 44.Can the Warburg effect regulation be targeted for cancer treatment? Question 45.Why do adenocarcinomas seldom occur in the small intestine? Question 46.Is Epstein-Barr virus infection a causal factor for nasal natural killer/T cell lymphoma formation? Question 47.Why will not all but very few human papillomavirusinfected patients eventually develop cervical cancer? Question 48.Why do cervical carcinomas induced by human papilloma virus have a low mutation rate in tumor suppressor genes? Question 49.Can viral infection trigger lung cancer relapse?展开更多

Three-hour pretreatment of cells with various concentrations of CSE (0, 0.1, 0.3, and 1%) dose-dependently reduced the number of lung metastatic nodules 14 days after tumor injection. To elucidate the mechanism of this anti-metastatic effect of CSE, we examined the invasion and migration activities of B16-BL6 cells pretreated with CSE for three hours in vitro. CSE significantly reduced the invasion of cells at 1% and the migration at 0.3% and 1%. Under the same pretreatment conditions, CSE had no effect on the proliferation of cells. These findings suggest that CSE contains some ingredients that suppress hematogenic lung metastasis via inhibition of the invasion and migration activities of mouse melanoma cells.展开更多

Herein, a chemo-immunotherapy was developed by encapsulating chemotherapeutic drug doxorubicin(DOX) and Toll-like receptor 7 agonist imiquimod(IMQ) in low molecular weight heparin(LMWH)-D-α-tocopheryl succinate(TOS) micelles(LT). In this process, LMWH and TOS were conjugated by ester bond and they were not only served as the hydrophilic and hydrophobic segments of the carrier, but also exhibited strong anti-metastasis effect. The direct killing of tumor cells mediated by DOX-loaded micelles(LT-DOX)generated tumor-associated antigens, initiating tumor-specific immune responses in combination with IMQ-loaded micelles(LT-IMQ). Furthermore, the blockade of immune checkpoint with programmed cell death ligand 1(PD-L1) antibody further elevated the immune responses by up-regulating the maturation of DCs as well as the ratios of CD8+ CTLs/Treg and CD4+ Teff/Treg. Therefore, such a multifunctional strategy exhibited great potential for inhibiting the growth of orthotopic and metastatic breast cancer.展开更多
