Abstract:
Cervical cancer is the fourth most common cancer and the leading cause of mortality among women worldwide. Tumor metastasis is an important cause of poor prognosis. Determining the exact mechanisms of metastasis and potential targeted therapies is urgently needed. Junctional adhesion molecule 3 (JAM3) is an important member of the TJ tight junction (TJ) family, and its biological function in cervical cancer needs to be further clarified. We found that JAM3 was highly expressed in cervical cancer patients with lymph node metastasis and that high expression of JAM3 promoted cervical cancer cell metastasis both in vitro and in vivo. In addition, overexpression of JAM3 induces epithelial-mesenchymal transition (EMT). Moreover, silencing JAM3 suppressed cervical cancer cell migration and invasion in vitro. Finally, JAM3 overexpression activated the HIF-1α/VEGFA pathway. In conclusion, our results suggested that JAM3 promotes cervical cancer cell migration and invasion by activating the HIF-1α/VEGFA pathway. JAM3 may be a promising biomarker and effective therapeutic target for cervical cancer.
Insights
Junctional adhesion molecule 3 (JAM3) promotes cervical cancer metastasis by activating the HIF-1α/VEGFA pathway. This finding suggests JAM3 could be a new therapeutic target for cervical cancer treatment.
Area of Science:
- Oncology
- Cell Biology
- Molecular Medicine
Background:
- Cervical cancer is a leading cause of cancer mortality in women globally.
- Tumor metastasis significantly worsens prognosis, necessitating research into its mechanisms and therapies.
- The role of Junctional Adhesion Molecule 3 (JAM3) in cervical cancer progression requires further elucidation.
Purpose of the Study:
- To investigate the function and mechanism of JAM3 in cervical cancer metastasis.
- To determine if JAM3 expression correlates with lymph node metastasis.
- To explore JAM3's potential as a therapeutic target.
Main Methods:
- Analysis of JAM3 expression in cervical cancer patient samples.
- In vitro and in vivo studies to assess the impact of JAM3 on cell metastasis.
- Investigation of JAM3's effect on epithelial-mesenchymal transition (EMT).
- Examination of the HIF-1α/VEGFA pathway activation by JAM3.
Main Results:
- High JAM3 expression was observed in cervical cancer patients with lymph node metastasis.
- Overexpression of JAM3 enhanced cervical cancer cell migration and invasion in vitro and in vivo.
- JAM3 induced epithelial-mesenchymal transition (EMT) in cancer cells.
- Silencing JAM3 reduced cancer cell migration and invasion.

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...
