Abstract: OBJECTIVE:Prolactinoma is a common intracranial tumor wihch always leads to serious clinical outcomes. This study aims to confirm the association between the proto-oncogene pokemon and prolactinoma progression, and further explore the molecular mechanisms. METHODS:Tumor tissues were collected from patients with prolactinoma. The primary prolactinoma cells were digested from the tissues and cultured with proper conditions. The expression of pokemon gene was knocked-down by siRNA transfection, and the proliferation of prolactinoma primary cells was analyzed by CCK8 assay. The expression level of pokemon related genes, cyclin-A, p14ARF and p21 in tissues and prolactinoma primary cells were examined by Western blot analysis. RESULTS:Expression of pokemon in prolactinoma primary cell was successfully knocked-down by siRNA transfection. The results showed that siRNA2 showed the highest efficiency of inhibiting the proliferation ability of prolactinoma primary cells. Cyclin-A, p14ARF and p21 were down-regulated by pokemon in both prolactinoma tissues and primary cells. CONCLUSION:Pokemon could improve prolactinoma progression by reducing the expression level of tumor inhibition factors, cyclin-A, p14ARF and p21.
