Abstract:
Objective We explored mechanism of microRNA-101-3p/Karyopherin α2 (KPNA2) axis in cervical squamous cell carcinoma. Methods: Bioinformatics methods were applied to identify genes for the study. Cell functional assays were implemented to examine the role of the genes in malignant progression of cervical squamous cell carcinoma. Targeting relationship between genes was verified by dual-luciferase assay. Results: MicroRNA-101-3p was lowly expressed in cervical squamous cell carcinoma, while KPNA2 was highly expressed. Dual-luciferase assay identified direct targeting relationship between microRNA-101-3p and KPNA2. Functional assays manifested that highly expressed microRNA-101-3p suppressed cervical squamous cell carcinoma cell growth by targeting KPNA2. Conclusion: Overall, microRNA-101-3p/KPNA2 axis can play an important part in progression of cervical squamous cell carcinoma.
Insights
MicroRNA-101-3p suppresses cervical squamous cell carcinoma progression by targeting Karyopherin α2 (KPNA2). This microRNA-101-3p/KPNA2 axis is a potential therapeutic target for cervical cancer.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Cervical squamous cell carcinoma (CSCC) is a significant global health concern.
- Understanding the molecular mechanisms driving CSCC progression is crucial for developing effective treatments.
Purpose of the Study:
- To elucidate the role of the microRNA-101-3p/Karyopherin α2 (KPNA2) axis in CSCC.
- To investigate the regulatory relationship between microRNA-101-3p and KPNA2 in CSCC.
Main Methods:
- Bioinformatic analyses were employed to identify key genes.
- In vitro cell functional assays were conducted to assess gene roles in CSCC progression.
- Dual-luciferase reporter assays confirmed the direct targeting interaction between microRNA-101-3p and KPNA2.
Main Results:
- MicroRNA-101-3p expression was found to be downregulated in CSCC tissues, whereas KPNA2 expression was upregulated.
- A direct targeting relationship between microRNA-101-3p and KPNA2 was confirmed.
- Overexpression of microRNA-101-3p inhibited CSCC cell proliferation and growth by targeting KPNA2.
Conclusions:
- The microRNA-101-3p/KPNA2 axis plays a critical role in the progression of cervical squamous cell carcinoma.
- Targeting this axis presents a potential therapeutic strategy for CSCC.

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
