Linoleic Acid Modulates the Expression of Metastatic and Angiogenic Markers MMP-2 and Talin-2 in Gastric Cancer Cell Line MKN-45

Abstract

Background: Linoleic acid (LA) has modulatory effects on gastric cancer cell lines. This study aimed to investigate the effects of linoleic acid on the expression of metastatic and angiogenic molecular markers in gastric cancer cell line MKN-45.

Methods: In this study performed in Tabriz, Iran in 2021, MKN-45 cells were treated with LA in the presence or absence of docetaxel. Total RNA was extracted, and cDNA synthesized from the cells before and after treatment. The expression levels of Talin-2 and MMP-2 genes and mir-20, mir-30, mir-126, and mir-194, were determined by quantitative real-time PCR.

Results: LA treatment reduced the expression levels of mir-126, mir-194, mir-30, and MMP-2, while increased the expression levels of Talin-2 mRNA. Docetaxel treatment could decrease the expression levels of mir-20, Talin-2, and MMP-2 mRNA levels while increasing the expression levels of mir-126, mir-194, and mir-30. Additionally, the combined treatment of MKN-45 cells with LA and docetaxel could reduce the expression levels of mir-20 and mir-126 and increased the expression levels of mir-194, mir-30, Talin-2, and MMP-2 mRNAs.

Conclusion: Modulation of the expression levels of gastric cancer involved microRNAs, Talin-2, and MMP-2 may be a mechanism through which LA may exert its biological effects on GC cell line MKN-45. LA may have an antimetastatic effect by reducing the MMP-2 expression and pro-angiogenic effect through increasing Talin-2 expression levels.
