NMB and cervical intraepithelial neoplasia: NMB mRNA was significantly increased in cervical cancer tissues as compared to that in cervix epithelium in the TCGA database (https://portal.gdc.com) (Fig. 2d), and its protein level was also increased in cervical cancer tissues, while not significantly elevated in cervical intraepithelial neoplasia (CIN) and cervical carcinoma in situ (CIS) tissues (Fig. 2e, f).
