In addition, deficiency of circ_0028826 might decrease Bcl2 protein level (an antiapoptosis marker) and increase Bax expression (a proapoptosis marker) and E‐cadherin expression (a specific marker for erythroid differentiation; increased E‐cadherin might repress cell invasion and migration) in NSCLC cells (Figure 2G). Here, CDH1 is linked to non-small cell lung carcinoma.
