ABSTRACT
Prolactinoma is an estrogen-related tumor and leukemia-related protein 16 (LRP16) is correlated with the progression of estrogen-related tumors, but the regulatory mechanism between LRP16 and prolactinoma remain unclear. This study demonstrates a variation in LRP16 with estrogen receptor α (ERα) in prolactinoma models and the up and downregulation effects of LRP16 on prolactin secretion of pituitary adenomas cells (GH3 cells). In our study, 50 male SD rats (30-day-old) were randomly divided into five groups of 10 rats each. After 120 days of treatment, the rats were sacrificed, and the expression of LRP16 and ERα were examined by Western blot and immunohistochemistry to explore the changes in ERα, LRP16, and prolactin. After siRNA transfection of the respective genes, the GH3 cells were cultured, and their secretory function as well as the expression of ERα mRNA and prolactin were analyzed by enzyme-linked immunosorbent assay and real-time-polymerase chain reaction analysis. The results show that secretion of prolactin by GH3 cells can be affected by up and downregulating LRP16 expression, which may provide a novel medical therapy in clinical trials.
