Abstract:
The incidence of lung cancer in China increases annually, and effective targets for the diagnosis and treatment of lung cancer are urgently needed. miRNAs are currently considered to be involved in the regulation of tumor development and growth. miR‑24 has been found to contribute to the development of several tumors. Menin is a key tumor suppressor gene, and its expression is generally low in lung cancer. The effects of miR‑24 on the biological behavior of lung cancer cells were detected by MTT and Transwell assays. In the present study, miR‑24 was found to be associated with menin, affecting the activity of the SMAD3 pathway in lung cancer by inhibiting menin expression. miR‑24 may promote the growth and metastasis and inhibit the apoptosis of lung cancer cells by targeting menin. Therefore, the aim of the present study was to provide a new theoretical basis for the targeted therapy of lung cancer.
Insights
MicroRNA-24 (miR-24) promotes lung cancer growth and metastasis by inhibiting the tumor suppressor menin. Targeting miR-24 may offer a new strategy for lung cancer treatment.
Area of Science:
- Oncology
- Molecular Biology
- Gene Regulation
Background:
- Lung cancer incidence is rising, necessitating novel therapeutic targets.
- MicroRNAs (miRNAs) play crucial roles in tumor development.
- Menin, a tumor suppressor, is downregulated in lung cancer.
Purpose of the Study:
- To investigate the role of miR-24 in lung cancer progression.
- To explore the relationship between miR-24, menin, and the SMAD3 pathway.
- To provide a theoretical basis for targeted lung cancer therapy.
Main Methods:
- Cellular biological behavior assessed using MTT and Transwell assays.
- miR-24 expression levels analyzed in relation to menin.
- SMAD3 pathway activity investigated in the context of miR-24 and menin.
Main Results:
- miR-24 was found to inhibit menin expression in lung cancer cells.
- miR-24 promoted lung cancer cell growth and metastasis.
- miR-24 suppressed lung cancer cell apoptosis by targeting menin.
- miR-24 affects the SMAD3 pathway activity by inhibiting menin.
Conclusions:
- miR-24 acts as an oncogenic miRNA in lung cancer by targeting menin.
- Inhibition of miR-24 may represent a potential therapeutic strategy for lung cancer.
- The miR-24/menin axis influences the SMAD3 pathway, impacting lung cancer progression.
