We performed an analysis about NF2 expression in breast cancer tissues by using UALCAN database (http://ualcan.path.uab.edu) Statistical analysis in the UALCAN database revealed that NF2 was down-expressed in breast cancer compared with the normal group, and the difference was statistically significant (P<0.05), as shown in Figure 1.A. The gene discussed is NF2; the disease is breast carcinoma.
