In the fragment "The expressions of c-Myc, Ki-67, MMp-2 ... in cancer tissues", one annotator chose "C1334508: MKI67 gene (Gene or Genome)-PART_OF-C0040300: Body tissue (Tissue)" and the other "C0040300: Body tissue (Tissue)-PRODUCES-C1334508: MKI67 gene (Gene or Genome)." We treat these cases as equivalent as well. Here, MMP2 is linked to cancer.
