[Expressions and clinical significance of caveolin-1 gene and protein in tongue squamous cell carcinoma].
OBJECTIVE
To investigate the changes and the significance of caveolin-1 gene and protein in tongue squamous cell carcinoma(TSCC).


METHODS
Immunohistochemical staining and in situ hybridization were used to detect the changes of caveolin-1 gene and the protein in 92 TSCCs and their adjacent normal tissues. The data were analyzed with SPSS10.0 software package.


RESULTS
The expressions of caveolin-1 gene(24.6+/-1.8) and its protein(471.2+/-68.1) in TSCC were lower than those of the control group(167.2+/-20.5, 964.5+/-77.2), respectively. The difference was significant(P<0.01). The expression of caveolin-1 protein in well-differentiated TSCC(5.6+/-1.4) was higher than that in moderately and poorly differentiated TSCC(1.3+/-0.8); The expression of caveolin-1 protein in stage I-II patients(6.1+/-2.0) was higher than that in stage III-IV patients(2.4+/-0.7), and the difference was significant(P<0.01). There was no significant relationship between the expression of caveolin-1 protein and cervical lymph node metastasis(P>0.05).


CONCLUSIONS
The level of caveolin-1 gene and the expression of the protein decrease in TSCC and the level of protein has a significant relationship with the clinical stage and the pathological grade, rather than the cervical lymph node metastasis.
