TLR4 and colonic neoplasm: Among 100 stage 3 colon cancers, significant associations between TLR4 expression and tumor recurrence were observed [29] with higher expression for all four probes among patients with recurrence compared to those without (p-values = 0.036, 0.076, 0.087, and 0.056 for probes Short, Probe, Long1, and Long2, respectively) (GSE5206).
