The mean co-expression rate of Cyclin D1with CK 5/6 or CK 8/18 in papilloma and papillary carcinoma cells. The mean co-expression rate of Cyclin D1 with CK 8/18 was 11.42% ± 10.17%, and that with CK 5/6 was 2.50% ± 3.24% (p < 0.01); whereas in papillary carcinomas, the mean co-expression rate of Cyclin D1 with CK 8/18 was 34.74% ± 16.32%, and that with CK 5/6 was 0.70% ± 0.93% (p < 0.01). The values are expressed as $\overline{X}$±SD.*P < 0.01 (Mann–Whitney U test). The differences exhibited statistical significance.
