NCBP3 and Familial prostate cancer: Consistently, we verified the expression of NCBP3 in human 293T embryonic kidney cells, glioma U251 cells, prostate cancer LNCapPC3 cells, non‐small‐cell lung cancer A549 cells and AC16 cardiomyocytes, and we found that NCBP3 was only highly expressed in AC16 with hypoxia treatment compared with normal control (Figure 4B).
