The study on clinical significance of the expression of EGFL7 in laryngeal squamous cell carcinoma / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To investigate the association and mechanism of EGFL7 expression level with the invasion and metastasis of laryngeal squamous cell carcinoma.@*METHOD@#RT-PCR and Western blotting were used respectively to detect the level of EGFL7 mRNA and protein form 33 fresh laryngeal carcinoma tissues and matched para-neoplastic non-tumor tissues. The immunohistochemistry technique was performed to determine microvessel density (MVD) in 33 tumor tissues. The association of EGFL7 expression and MVD with clinicopathological characteristics was analyzed.@*RESULT@#EGFL7 mRNA and protein expression were both significantly higher in the tumor tissues than in the paraneoplastic non-tumor tissues (P 0.05).@*CONCLUSION@#EGFL7 may have a close correlation with the development of laryngeal carcinoma via its impact on tubulogenesis and vessel shape. EGFL7 might serve as a tumor marker for assessing the progression of laryngeal carcinoma and a guide of clinical therapeutic decisions.
