Figure 2. (A) RT-PCR detection of circUBAP2_046 expression level between NSCLC and matched normal tissue samples. (B) Relative circUBAP2_046 expression ratio distribution of NSCLC and matched normal tissue samples. (C) RT-PCR detection of UBAP2 expression level between NSCLC and matched normal tissue samples. (D) RT-PCR detection of circUBAP2_046 expression level between early stage (I/II) and advanced stage (III/IV) NSCLC samples. (E) RT-PCR detection of circUBAP2_046 expression level between NSCLC samples with/without lymph node metastasis. (F) RT-PCR detection of circUBAP2_046 expression level among different NSCLC cell lines (NCI-H1299, NCI-H1395, A549, NCL-H460) and human normal bronchial epithelial cell line HNBE.
