A microarray study by Ueda et al. [81] found the combination of NUS1 and RCN1 mRNAs to accurately distinguish OSCC patients from controls and indicated that this combination can be implemented as a screening test for OSCC; the lower expression of NAB2, CYP27A1, NPIPB4, MAOB, and SIAE was noted for the OSCC group compared to the non-tumor group. The gene discussed is NAB2; the disease is neoplasm.
