Biological Activity

Description APTSTAT3-9R is a specific STAT3-binding peptide with addition of a cell-penetrating motif. The treatment of APTSTAT3-9R in various types of cancer cells blocks STAT3 phosphorylation and reduces expression of STAT targets.
Targets
STAT3 [1]
(In A549 cells)
In vitro APTSTAT3-9R effectively inhibited phosphorylation of STAT3 but did not affect the level of AKT phosphorylation and it suppresses cell viability and proliferation of cancer cells[1].
In vivo APTSTAT3-9R could effectively suppress tumor growth in the in vivo allograft and xenograft tumor models by inhibiting STAT3 phosphorylation[1].

Protocol (from reference)

Cell Assay:[1]
  • Cell lines

    A549 cells

  • Concentrations

    0-100 μmol/L

  • Incubation Time

    12 h

  • Method

    Cells are plated in a 96-well plate (5,000 cells/well) and incubated for 12 hours. After incubation the cells are treated with nine-arginine (9R), APTSTAT3-9R, and APRscr-9R for 12 hours. After 12 hours incubation, 20 μL MTT (5 mg/mL) is added to each well. After 4 hours, 100 μL dimethyl sulfoxide is added to each well, and absorbance is measured at 570 nm using a Spectra Macplus microplate reader
Animal Study:[1]
  • Animal Models

    Human lung carcinoma xenograft model(by subcutaneous implantation of A549 cancer cells into female BALB/c nude mice)

  • Dosages

    8 mg/kg

  • Administration

    intratumoral injection
