[Expression of phosphofructokinase 1 protein and it's enzyme activity on nasopharyngeal carcinoma].

OBJECTIVE

The aim of this study is to investigate the expression of phosphofructokinase 1 and it's enzyme activity in nasopharyngeal carcinoma biopsy samples.

METHOD: Sixty-one biopsy samples were detected, including 41 tissues from patients with nasopharyngeal carcinoma as experimental group and 20 tissues from patients with chronic nasopharyngitis as control group. Phosphofructokinase 1 protein was detected by Western blot and it's enzyme activity was detected.

RESULT: It was observed that the expression levels of phosphofructokinase 1 protein and it's enzyme activities in the experimental group were higher than that in the control group (P < 0.01). In the experimental group, the expression levels of phosphofructokinase 1 protein and it's enzyme activities in patients with lymph node metastasis were higher than that in patients without lymph node metastasis (P < 0.01).

CONCLUSION

Phosphofructokinase 1 may be a marker in occurrence and metastasis of nasopharyngeal carcinoma.
