Expression of CDK11 in normal prostate tissues and prostate cancer tissues. (A) Prostate cancer tissues were lysed and subject to immunoblotting analysis as indicated. Protein levels were normalized to GAPDH. (B) 20 pairs of prostate cancer tissues and normal tissues were subject to qRT-PCR as described above. The relative mRNA level was showed above. P < 0.05. (C) CDK11 and Cyclin D3 immunostaining was performed in normal postate tissues (a) and its paired cancer tissues (b); All photomicrographs were amplified 400×.
