Synergistic IL-6 and IL-8 paracrine signalling pathway infers a strategy to inhibit tumour cell migration

Tumor cell proliferation and migration, key drivers of metastasis, can be mechanistically coupled in matrix embedded human sarcoma and carcinoma cells through cell density via a synergistic, paracrine signaling mechanism between Interleukins 6/8. Inhibition of this mechanism significantly decreases metastasis in mouse xenograft models.
