Objective:
The purpose of study was to examine the mRNA expression levels of the metastasis-associated gene1 (MTA1) in laryngeal squamous cell carcinoma (LSCC), so to evaluate its relationship with metastases.
Methods:
Forty-eight surgically resected primary LSCC (16 supraglotti laryngeal carcinomas with cervical lymph node metastasis, 16 supraglotti laryngeal carcinomas with cervical lymph node-negative metastasis, 16 glottic carcinoma with cervical lymph node-negative metastasis) and 16 normal laryngeal mucosa was examined for mRNA expression of MTA1 by reverse transcription-polymerase chain reaction(RT-PCR).
Results:
The frequency of MTA1 mRNA positive expression in 16 LSCC with cervical lymph node metastasis was 100%, but no expression of MTA1 mRNA was observed in other LSCC with cervical lymph node-negative metastasis (16 supraglotti laryngeal carcinomas and 16 glottic carcinoma) and 16 normal laryngeal mucosa.
Conclusion:
MTA1 gene is strongly related to cervical lymph node metastasis of LSCC, and may serve as a early diagnosis indicator.

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...
