Gipie-silencing conferred a “lymphoblast-like” morphology to ACC cells, a six-fold increase in apoptotic cells (compared to unaltered ACC cells, P ≤ 0.0001), a two-fold decrease in T regulatory cells (FoxP3+/IL-2Rα+/CD25+) (P ≤ 0.0001), and a three-fold increase in activated NK cells (NKp30+/IFN-γ+) (P ≤ 0.0001) with significantly higher release of granzyme (P ≤ 0.001) and perforin (P ≤ 0.0001). Here, IFNG is linked to adrenal cortex carcinoma.
