Abstract 한글 요약
Metastasis accounts for most cancer-related deaths and hepatocellular carcinoma (HCC) is no exception. Midkine (MDK) is a multifunctional secreted protein elevated in HCC with a vague role in HCC. In this study, we used bioinformatics to verify MDK expression in HCC tumors, and next, we inhibited the MDK protein in invasive Hep3B cells using an MDK inhibitor (iMDK) both in vitro and in vivo. Our results showed that iMDK promoted cell migration and enhanced lamellipodia formation while at the same time downregulating the expression of cell-matrix adhesion genes. In order to also consider forces exerted by the surrounding matrix, we performed cell adhesion, transwell invasion, and 3D tumor spheroid invasion assays in two different stiffness conditions. Adhesion and invasion always exhibited opposite patterns, with adhesion being inhibited in soft matrix environments, accompanied by increased invasion, and a reverse effect in stiff environments. In vivo experiments where cells pre-treated with iMDK were implanted to zebrafish embryos showed overall reduced metastasis, verifying that MDK is a central mechanotransduction regulator that enables HCC cells to adapt their metastatic strategies to ECM stiffness. Thus, MDK inhibition effectively disrupts mechanosensitive coordination during metastasis, highlighting its potential as a therapeutic target.
