NIT1 and neoplasm: Immunohistochemistry also demonstrated a lack of Nit1 expression in knockout strains in both tumor and the surrounding lung tissues, while positive staining of Nit1 can be found in the nucleus and cytoplasm of wild-type mice lung tissue cells (Figure 1C), which is consistent with Huebner's data [14] and the Human Protein Atlas (HPA) Nit1 datasets [http://www.proteinatlas.org/ENSG00000158793-NIT1/tissue/lung].
