Abstract
To explore the inhibitory effect of non-functioning pituitary adenoma (NFPA) cells after a combined treatment of adenovirus mediated D2S gene and bromocriptine in vitro. Adenovirus containing dopamine 2 receptor short isoform (D2S) gene was used to infect NFPA cells. The transfection of D2S gene into NFPA cells was confirmed by immunofluorescence. And cell apoptosis of infected cells treated by bromocriptine was evaluated with CCK-8 assay in vitro. When D2S gene transfection and bromocriptine was used in combination, the survival rate of NFPA cells significantly decreased (40 ± 5)% versus the control group (97 ± 5)% and the pAd-EGFP transfection combined bromocriptine treatment group (90 ± 9)% (P < 0.05). The combined treatment of adenovirus-mediated D2S gene and bromocriptine can effectively induce the apoptosis of NFPA cells on primary culture and increase the sensitivity of NFPA to dopamine agonist.
