Metformin interrupts bidirectional signaling between tumor and mesothelial cells by blocking OvCa cell TGF-β signaling and mesothelial cell production of CCL2 and IL-8.
In a prospective cohort comprising 45 women with ovarian cancer, IL-10 (interleukin), VEGF (vascular endothelial growth factor), TGF-β (transforming growth factor) and CCL-2 [chemokine (C-C) motif ligand 2] were measured at diagnosis (and at interval debulking, when available).
These data suggest that MCP-1rs1024611A/G and rs3760396C/G polymorphisms are associated with increased susceptibility to ovarian cancer, in which rs1024611A/G may increase serum level of MCP-1 in the Chinese population.
In the current study, we investigated the effect of MCP-1 on ovarian cancer by examining the association between MCP-1 genetic polymorphisms and the susceptibility to ovarian cancer.
We reported previously that vascular endothelial growth factor and monocyte chemotactic protein-1 contribute to TNFSF15 downmodulation in ovarian cancer.
The association of CCL2 expression with chemotherapy response, invasion and survival outcomes was studied in patients with primary ovarian cancer (OC) and in ovarian cancer cell lines (OCCLs).
Chemotherapy induction of MCP-1 in ovarian cancer suggests this chemokine plays an important role in the immune response occurring after chemotherapy exposure.
These data support the hypothesis that CCL2 may play a role in the pathobiology of ovarian cancers, but additional studies will be required to evaluate this possibility.
