We further compared the proportion of BRD4 expression between tumor and para-tumor tissues, we found that BRD4hi level in NSCLC tissues accounted for 46.15% (96 of 208), which was higher than that in para-tumoral tissues (32.21%, 67 of 208) (p = 0.005, Figure 4B). The gene discussed is BRD4; the disease is non-small cell lung carcinoma.
