Background:
Cervical cancer is a common malignant gynecological disease that threatens the health of women all over the world. The abnormal expression of Annexin A5 (ANXA5) is closely related to the biological behavior of various malignant tumors, however, the relationship between ANXA5 and cervical cancer is still unclear. Therefore, the effects of low expression of ANXA5 on the proliferation, apoptosis, migration and invasion of cervical cancer cells (HeLa) and its related mechanism were explored.
Methods:
The cells were divided into three groups: ANXA5-si group, negative control group and blank group. RNA interference was used to suppress ANXA5 expression. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, colony formation assay, flow cytometry and propidium iodide (PI) staining, wound healing assay and transwell assay were employed to detect cell proliferation, apoptosis, migration and invasion respectively. Meanwhile, gene expression was detected by qPCR and Western blotting.
Results:
ANXA5 suppression lead to the increase of proliferation, migration, invasion and the decrease of apoptosis of cervical cancer HeLa cells. Furthermore, the expression of both pPI3K and pAkt increased.
Conclusion:
ANXA5 might inhibit Hela cells proliferation and metastasis by regulating PI3K/Akt signal pathway.
Insights
Low Annexin A5 (ANXA5) expression in cervical cancer cells promotes proliferation and metastasis. This occurs via the PI3K/Akt signaling pathway, suggesting ANXA5 as a potential therapeutic target.
Area of Science:
- Oncology
- Molecular Biology
Background:
- Cervical cancer is a significant global health concern for women.
- Annexin A5 (ANXA5) expression is linked to various cancers, but its role in cervical cancer remains unclear.
Purpose of the Study:
- To investigate the effect of reduced ANXA5 expression on cervical cancer cell behavior (proliferation, apoptosis, migration, invasion).
- To explore the underlying molecular mechanisms, specifically the PI3K/Akt pathway.
Main Methods:
- RNA interference was used to suppress ANXA5 expression in HeLa cells.
- Cell proliferation, apoptosis, migration, and invasion were assessed using MTT, colony formation, flow cytometry, wound healing, and Transwell assays.
- Gene expression was analyzed via qPCR and Western blotting.
Main Results:
- ANXA5 suppression increased proliferation, migration, and invasion of cervical cancer cells.
- Apoptosis decreased in ANXA5-suppressed cells.
- Increased expression of phosphorylated PI3K (pPI3K) and phosphorylated Akt (pAkt) was observed.
Conclusions:
- ANXA5 may inhibit cervical cancer cell proliferation and metastasis.
- The PI3K/Akt signaling pathway appears to be involved in ANXA5's regulatory role in HeLa cells.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

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...
