Abstract

Tripeptide compound tyroservaltide (YSV) has obvious inhibitory effect on experimental liver cancer. This study was to evaluate the inhibitory effect of YSV on the invasion and metastasis of mouse melanoma cell line B16-F10. The cytotoxic effect of YSV on B16-F10 cells was assessed by MTT assay, and the effects of YSV on the adhesiveness and invasiveness of B16-F10 cells were determined using Matrigel and a transwell system. B16-F10 cells were injected into the tail veins of C57BL/6 mice to establish an experimental lung metastasis model, and the effect of YSV on lung metastasis was observed. The effect of YSV on the expression of intercellular adhesion molecule-1 (ICAM-1) in lung tissue was detected by immunohistochemistry. YSV (100 microg/ml, 48 h) inhibited the proliferation of B16-F10 cells, with an inhibitory rate of 24.36%; YSV (100 microg/ml, 24 h) inhibited the adhesiveness of B16-F10 cells to Matrigel, with an inhibitory rate of 36.51%; YSV (10 microg/ml, 48 h) inhibited the invasiveness of B16-F10 cells, with an inhibitory rate of 36.53%; YSV [640 microg.(kg.d)-1] inhibited lung metastasis by B16-F10 cells, with an inhibitory rate of 62.21%. The expression of ICAM-1 in lung tissue was lower in YSV group than in normal...Continue Reading

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
