Moreover, the mRNA and protein levels of DLG2 were downregulated in cervical cancer cells (SiHa and C33A) when compared with human cervical endometrial epithelial cells (End1/E6E7), as shown in Fig. 1F and G. Thus, these data demonstrate that DLG2 expression is downregulated in cervical cancer tissues and cells. Here, DLG2 is linked to cervical carcinoma.
