In lung cancer tissue samples, KRAB‐ZNF staining was positive for at least four analyzed tumor samples (ZNF205 – 4/12, ZNF320 – 10/10, ZNF485 – 11/11, ZNF643 – 10/11, ZNF695 – 8/9, ZNF 707 – 10/11) and at least one sample from each set presented nuclear localization of a given factor (Fig. 2E). This evidence concerns the gene ZNF320 and lung carcinoma.
