Moreover, mRNA and protein expression levels in the MEC-1 and EHEB cell lines were detected noticeably higher than that in both normal CD19 + B cells of healthy donors and other cancer cells such as U87 (glioblastoma cell line), HELA (cervical cancer cell line), SKOV3 (ovarian cancer cell line) cells (p < 0.001) (Fig. 1C, D). The gene discussed is CD19; the disease is cervical carcinoma.
