[Expression and significance of integrin beta1 and integrin-linked kinase in laryngeal carcinoma].
OBJECTIVE
To study the expressions and clinical significance of integrin beta1 and integrin-linked kinase(ILK) in laryngeal carcinoma (LSCC).


METHODS
The mRNA and protein levels of integrinbeta1 and integrin-linked kinase in 43 specimens of laryngeal carcinoma, its surrounding tissue and 18 specimens of vocal cord polyp were detected by reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemistry SABC method.


RESULTS
The mRNA levels of integrin beta1 and ILK protein were significantly higher in laryngeal carcinoma than that in its surrounding tissue and vocal cord polyp (P < 0.05). There was significant correlation between the levels of integrin beta1 expression and the status of cervical lymph node, either between the level of ILK expression and cervical lymph node status (P < 0.05). There was significant correlation between the levels of integrin beta1 expression and T-category, either between the level of ILK expression and T-category (P < 0.05). But pathological grades was not significantly related with the level of integrin beta1 or ILK expression (P > 0.05).


CONCLUSIONS
The expressions of integrin beta1 and ILK are increased in LSCC. Integrin beta1 and ILK may contribute significantly to invasion and metastasis of LSCC.
