Abstract

Background

Adenocarcinoma of the pancreas (PAAD) is one of the most malignant tumors in the gastrointestinal tract. Long-chain noncoding RNAs (lncRNAs) are non-coding RNAs that are expressed in a variety of cancers. The purpose of this study is to study the expression, biology functions, and molecular mechanism of lncRNA SNHG17 in PAAD.

Methods

In this study, qRT-PCR was used to measure the relative expression of SNHG17 and miR-32-5p in PAAD. In order to investigate the effect of SNHG17 and miR-32-5p on the proliferation, migration and invasion of PAAD cells, we performed a variety of tests including CCK-8, colony formation, scratch and transwell assays. Furthermore, SNHG17 and miR-32-5p interactions were confirmed by a luciferase reporter gene test.

Results

Our results indicate that the expression of SNHG17 in PAAD is elevated, and in vitro studies have shown that SNHG17 enhances the proliferation of PAAD cells, Mechanistically, it has been shown that SNHG17 can direct target miR-32-5p in PAAD cells, thus promoting the proliferation of PAAD cells, migration, and invasion. Furthermore, SNHG17 has been found to activate EZH2/STAT3 signaling pathway through miR-32-5p in PAAD cells.

Conclusion

Our results show that SNHG17 plays a key role in the progression of PAAD by activating STAT3 signaling via regulation of miR-32-5p and EZH2.Identifying these new regulatory pathways may shed light on the underlying mechanism of PAAD and offer a potential therapeutic target for this fatal disease.
