Abstract
Background: Aloperine (ALO) is an important active component of quinolizidine alkaloids in Sophora flavescens A and Sophora alopecuroides L, and has effective anticancer activity against multiple cancers. However, the influence and mechanism of ALO on migration, invasion, and adhesion in bladder cancer cells remain unclear.
Objective: The aim of this study is to determine the anticancer effect of ALO on migration, invasion, and adhesion in bladder cancer cells and to investigate its potential TIMP-4-related mechanism.
Methods: Cell viability, cytotoxicity, wound healing, Transwell invasion, cell adhesion, real-time qPCR, western blot, and ELISA assays were performed to analyze the effect of ALO on migration, invasion, and adhesion in bladder cancer 5637 and UM-UC-3 cells. Furthermore, the anti-TIMP-4 antibody was used to explore the potential effect on ALO-inhibited bladder cancer cells.
Results: We have found that ALO significantly suppressed migration, invasion, and adhesion in bladder cancer cells. Furthermore, ALO could downregulate the expression of MMP-2 and MMP-9 mRNAs and proteins, and increase the expression of TIMP-4 mRNA and protein. Moreover, the anti- TIMP-4 antibody reversed the prevention of migration, invasion, and adhesion in ALO-treated bladder cancer cells.
Conclusion: The data in this study suggest that ALO suppressed migration, invasion, and adhesion in bladder cancer cells by upregulating the expression of TIMP-4.
期刊介绍：
Protein & Peptide Letters publishes letters, original research papers, mini-reviews and guest edited issues in all important aspects of protein and peptide research, including structural studies, advances in recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, and drug design. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallization and preliminary structure determination of biologically important proteins are considered only if they include significant new approaches or deal with proteins of immediate importance, and preliminary structure determinations of biologically important proteins. Purely theoretical/review papers should provide new insight into the principles of protein/peptide structure and function. Manuscripts describing computational work should include some experimental data to provide confirmation of the results of calculations.
Protein & Peptide Letters focuses on:
Structure Studies
Advances in Recombinant Expression
Drug Design
Chemical Synthesis
Function
Pharmacology
Enzymology
Conformational Analysis
Immunology
Biotechnology
Protein Engineering
Protein Folding
Sequencing
Molecular Recognition
Purification and Analysis
