Biological Activity

Description GO-203 is a D-amino acid cell-penetrating peptide inhibitor of MUC1-C dimerization and thereby its oncogenic function.
Targets
MUC-1C [1]
In vitro GO-203 inhibits MUC1-C homodimerization which blocks its oncogenic function. Treatment of MUC1-overexpressing SKCO-1 and Colo-205 colon cancer cells with GO-203 is associated with downregulation of the TP53-inducible glycolysis and apoptosis regulator (TIGAR) protein. GO-203 regulates AKT-S6K1-elF4A signaling in colorectal cancer cells. Targeting MUC1-C with GO-203 inhibits p-AKT in colorectal cancer cells. GO-203 treatment also results in increases in reactive oxygen species (ROS) and loss of mitochondrial transmembrane potential[1].
In vivo GO-203 is effective in inhibiting growth and survival of MUC1-positive colorectal cancer cells in mouse xenograft models. It is also effective in xenografts models of breast, prostate, lung and certain hematologic malignancy[1].

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    Human SW480 and LOVO colorectal cancer cells

  • Concentrations

    5 μM

  • Incubation Time

    48 h

  • Method

    To assess cell viability, 20,000–30,000 cells are plated and cultured for 48 h. GO-203 and CP-2 are added at 5 μM every day for six days. Cell viability is measured by trypan blue exclusion.
Animal Study:

[1]
  • Animal Models

    BALB/c nu/nu male/female mice with xenograft tumor

  • Dosages

    18 mg/kg

  • Administration

    i.p.
