Together, our results indicated that IL-8 triggered ovarian cancer cells migration partly through Wnt/β-catenin pathway mediated EMT, and IL-8 may be an important molecule in the invasion and metastasis of ovarian cancer.
The addition of VEGF, IGF-1, and IL-8 weakened the inhibitory effect of DIRAS3 on ERK/AKT activity and reduced DIRAS3-mediated TFEB or FOXo3a nuclear localization and MAPLC3B expression in ovarian cancer cells.
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 addition, our data indicate that the induced CXCL8 expression may be responsible for the limited effectiveness of HDAC inhibitors in OC and perhaps other solid cancers characterized by CXCL8 overexpression, and suggest that targeting class I HDACs and CBP may provide novel combination strategies by limiting the induced CXCL8 expression.
Significant associations were noted in patients with the IL-8 +781 (T/T) genotype (p=0.0048) with increased frequencies of ovarian cancer, while women with the IL-8 +781 (C/C) allele suffer from ovarian cancer significantly less frequently (p=0.0003).
Therefore, modulation of IL-8 expression or its related signaling pathway may be a promising strategy for controlling the progression and metastasis of OVCA.
We analyzed the expression of LPA receptors, vascular endothelial growth factor (VEGF), and interleukin-8 in 97 patients from normal ovary to ovarian cancer, using reverse transcription polymerase chain reaction.
