Immunohistochemical analysis of lung tissue from tumor-bearing mice intubated with GATAD2B-Cre virus confirmed strong GATAD2B expression and Ki-67 positive nuclei (Fig. 4h), and immunoblot analysis confirmed elevated levels of GATAD2B protein in the lungs of mice intubated with GATAD2B-Cre virus compared to GFP-Cre control virus (Fig. 4i). Here, MKI67 is linked to neoplasm.
