[Inhibitory effect of tumor suppressor PTEN on cell growth of endometrial carcinoma].
OBJECTIVE
To evaluate the inhibitory effect of tumor suppressor PTEN on cell growth of endometrial carcinoma.


METHODS
The exogenous wild PTEN cDNA via an adenoviral vector (Ad-PTEN) was introduced into Ishikawa cells. The expression of PTEN protein was detected by Western blot. The growth of Ishikawa cells was evaluated by trypan blue exclusion method and MTT.


RESULTS
The expression of PTEN protein was induced on day 1, and greatly increasing on day 3 - 5 after Ad-PTEN infection. The expression of PTEN significantly inhibited the growth of Ishikawa cells, and also significantly inhibited the growth of Ishikawa cells induced by IGF-II.


CONCLUSIONS
Adenovirus-mediated introduction of exogenous PTEN into human endometrial carcinoma cells can induce growth suppression. PTEN gene may be a novel therapeutic agent for endometrial carcinoma.
