IHC analysis results revealed that circ_000829 overexpression reduced Ki-67 positive cells in tumor tissues, and that overexpression of circ_000829 diminished the expression of SRSF1 and UBE2C (proliferation- and invasion-related marker) in the tumor tissues (Figures 6(c) and 6(d)). The gene discussed is MKI67; the disease is neoplasm.
