Abstract:
Long non-coding RNAs (lncRNAs) are implicated in the initiation and progression of a variety of tumors, including endometrial cancer. However, the mechanisms of lncRNA in endometrial cancer formation and progression remain largely unknown. In this study, we confirmed that the lncRNA SNHG4 is upregulated in endometrial cancer and correlates with lower survival rates in endometrial cancer patients. Knock-down of SNHG4 significantly reduced cell proliferation, colonization, migration, and invasion in vitro, as well as modulating the cell cycle and reduced tumor growth of endometrial cancer in vivo. In addition, the effect of SNHG4 by the transcription factor SP-1 was confirmed in vitro. We found in this study that SNHG4/SP-1 plays an important role in endometrial cancer progression and may be used as a potential therapeutic and prognostic biomarker for endometrial cancer.
Insights
The long non-coding RNA SNHG4 is elevated in endometrial cancer, driving tumor progression and reducing patient survival. Targeting SNHG4 shows promise for new endometrial cancer therapies.
Area of Science:
- Molecular Oncology
- Cancer Biology
- Genetics
Background:
- Long non-coding RNAs (lncRNAs) are increasingly recognized for their roles in various cancers.
- The specific involvement and mechanisms of lncRNAs in endometrial cancer pathogenesis are not fully understood.
- Endometrial cancer is a significant gynecological malignancy with a need for improved therapeutic targets.
Purpose of the Study:
- To investigate the role of the lncRNA SNHG4 in endometrial cancer.
- To elucidate the molecular mechanisms underlying SNHG4's function in endometrial cancer.
- To evaluate SNHG4 as a potential biomarker for prognosis and therapy in endometrial cancer.
Main Methods:
- Quantitative real-time PCR to assess SNHG4 expression levels in endometrial cancer tissues.
- In vitro assays (proliferation, migration, invasion, cell cycle analysis) following SNHG4 knockdown.
- In vivo tumor xenograft models to evaluate the effect of SNHG4 on tumor growth.
- Investigation of the regulatory interaction between SNHG4 and the transcription factor SP-1.
Main Results:
- SNHG4 expression is significantly upregulated in endometrial cancer tissues and correlates with poor patient survival.
- Knockdown of SNHG4 suppressed endometrial cancer cell proliferation, migration, invasion, and tumor growth in vivo.
- SNHG4 influences the cell cycle and its activity is regulated by the transcription factor SP-1.
Conclusions:
- The lncRNA SNHG4 plays a critical role in promoting endometrial cancer progression.
- The SNHG4/SP-1 axis is a key pathway involved in endometrial cancer development.
- SNHG4 represents a promising therapeutic target and prognostic biomarker for endometrial cancer.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
