The quantificational real-time polymerase chain reaction (qRT-PCR) analysis on a panel of lung cancer complementary DNA (cDNA) arrays including 40 patients with lung cancer and seven healthy controls demonstrated that B-Myb was significantly up-regulated at the mRNA level in lung cancer samples compared with normal lung tissues (p = 0.002; Figure 1A). The gene discussed is MYBL2; the disease is lung carcinoma.
