Moreover, our findings showed that the expression of LINC00909 in the tumor was obviously associated with that in serum with an R2 of 0.5604 (p < 0.001) (Figure 3(c)), implying that the elevation of serum LINC00909 may be the result of high LINC00909 expression in tumors. The gene discussed is ZNF407-AS1; the disease is neoplasm.
