S3I-201, a Novel STAT3 Inhibitor, Inhibits Growth of Human Soft Tissue Sarcoma Cell Lines
Background: STAT3 has been identified as a novel target to treat and prevent cancers with a broad potential application. Aim: To investigate whether constitutive STAT3 plays a role in the survival and growth of soft tissue sarcoma (STS) cell lines. Materials and Methods: Expression and activity of STAT3 were characterized by Western blot and Immunohistochemistry staining. S3I-201 in different doses or vehicle was added into cell culture respectively. Cell growth and colony formation were determined using crystal violet colorimetric and clonogenic assays. Results: Western blot demonstrated 5 out of 6 STS cell lines expressed constitutively activated STAT3. STAT3 inhibitor S3I-201 mono-therapy induced anti-proliferative effects on majority of STS cell lines harboring aberrant STAT3 by blocking STAT3 phosphorylation. Conclusion: Our study demonstrated that a high level of STAT3 phosphorylation is present in the human STS cell lines that we examined. Furthermore targeting STAT3 is a potential novel approach to pursue in anti-sarcoma therapy.
