STAU2 and breast cancer: The average fluorescence intensity of anti-STAU2 and the percentage of positive cells in breast cancer patients (110.50 ± 23.38 and 61.87 ± 12.44) were significantly increased compared with those in healthy females (56.47 ± 32.03 and 33.02 ± 18.10) (p = 3.56 × 10–71, odds ratio = 24.59, 95% CI = 16.64–36.34) at cut-off point B. In addition, all WBC samples (N = 721) were obtained and subjected to double-blind experiments.
