Also, transfection of Ik-1 and MZF1 was associated with decreased cell viability, proliferation, migration, and anchorage-independent colony formation of NPM-ALK+ T-cell lymphoma cells, asserting the tumor-suppressing impact of Ik-1 and MZF1 in this lymphoma. The gene discussed is MZF1; the disease is T-cell non-Hodgkin lymphoma.
