LncRNA SNHG7 Functions as an Oncogene in Cervical Cancer by Sponging miR-485-5p to Modulate JUND Expression

Area of Science:

• Oncology
• Molecular Biology
• Genetics

Background:

• Long non-coding RNA (LncRNA) SNHG7 is implicated in various cancers.
• The specific role of SNHG7 in cervical cancer (CC) progression remains unclear.
• This study investigates the function and mechanism of SNHG7 in CC.

Purpose of the Study:

• To elucidate the role of SNHG7 in cervical cancer progression.
• To explore the underlying molecular mechanisms involving SNHG7.
• To identify potential therapeutic targets for cervical cancer.

Main Methods:

• Quantitative real-time PCR (qPCR) to measure SNHG7 and miR-485-5p expression.
• In vitro assays (CCK-8, wound healing, Transwell, flow cytometry) to assess cell proliferation, migration, invasion, and apoptosis.
• Luciferase reporter assays, Western blot, and RNA immunoprecipitation (RIP) to investigate the SNHG7/miR-485-5p/JUND pathway.
• In vivo tumor xenograft models to validate findings.

Main Results:

• SNHG7 expression was significantly elevated in CC tissues and cell lines, correlating with poor clinical characteristics.
• Knockdown of SNHG7 suppressed CC cell proliferation, migration, and invasion, while enhancing apoptosis.
• SNHG7 upregulates JUND expression by sponging miR-485-5p, a mechanism confirmed in vitro and in vivo.
• MiR-485-5p inhibition partially reversed the effects of SNHG7 knockdown.

Conclusions:

• SNHG7 promotes cervical cancer progression via the miR-485-5p/JUND axis.
• The identified SNHG7/miR-485-5p/JUND pathway represents a promising novel therapeutic target for cervical cancer treatment.
