Overexpression of HOTTIP in OC tissues enhances the expression of PD-L1 in neutrophils. a HOTTIP expression in OC tissues and normal fallopian tube fimbriae tissues as determined by RT-qPCR. b Analysis of the relationship between expression of HOTTIP and the OS of patients with OC by Kaplan-Meier analysis. c The correlation between the expression of HOTTIP and IL-6. d The correlation between the expression of HOTTIP and PD-L1. ^* p < 0.05 vs. normal fallopian tube fimbriae tissues; ^# p < 0.05 vs. the IL-6(−/+); ^& p < 0.05 vs. patients with lower expression of HOTTIP. The measurement data were summarized as mean ± standard deviation. The unpaired t test was used to compare the data between two groups. The experiment was repeated 3 times independently
