| Description | Tyroserleutide (YSL), a small molecular tripeptide isolated from porcine spleen degradation products, inhibits the growth and metastasis of human hepatocellular carcinoma (HCC) both in vitro and in vivo. |
| In vitro | Tyroserleutide (YSL) exhibits immunomodulatory properties, notably enhancing concanavalin (ConA) induced proliferation of mouse spleen lymphocytes, augmenting phagocytosis in mouse peritoneal macrophages, and boosting natural killer (NK) cell activity[1]. Additionally, as an immunotherapeutic tripeptide, YSL promotes apoptosis in hepatocarcinoma cells (H22) by downregulating Bcl-2 and cyclin D1 expression[2], establishing it as an effective agent for liver tumor cell apoptosis induction[2]. Moreover, YSL effectively inhibits tumor growth and cell migration without causing significant toxicities in major organs[2]. |
