CYYR1 and neoplasm: The CYYR1 CAG- expression level was significantly lower in tumor samples in comparison with normal tissues at an approximate ratio of 2:3 (p = 0.022; mean ± standard deviation: tumors, 0.92 ± 0.25; normal tissues, 1.31 ± 0.76), while the difference in the CYYR1 CAG+ expression level between tumors and normal tissues was not significant (mean ± standard deviation: tumors, 0.15 ± 0.13; normal tissues, 0.15 ± 0.10).
