Abstract:
Aim: Being the common cause and major burden of deaths globally, timely cancer management
is crucial.
Background: Thymic immunosuppressive pentapeptide (TIPP) is a novel pentapeptide originally
obtained from calf thymic immunosuppressive extract. Previously, TIPP has been proved to suppress
the allergic and inflammatory responses in allergic mice via blocking MAP kinases/NF-κB
signaling pathways.
Objective: In this study, in vitro anticancer activity of TIPP was tested on two different types of
cancers using MCF-7 and K562 cell lines.
Methods: Tumor xenograft models for breast cancer and chronic myeloid leukemia were designed.
In vivo anticancer activity of TIPP was investigated on both cancer types. The liver and tumor tissues
of the mice were preserved for immunohistochemistry analysis.
Results: In vitro anticancer activity of TIPP showed significant inhibition on cell viability of both
breast cancer and chronic myeloid leukemia. In vivo anticancer effect of TIPP in both types of cancer
models further proved the potent anticancer nature of TIPP. Immunohistochemistry analysis assured
that TIPP is a safe drug for normal organs such as the liver.
Conclusion: Our present study revealed that TIPP is a potent anticancer drug and an important
treatment option for various diseases. Further work is needed to test the flexible and proficient activity
of the novel peptide.
