Aim: To determine the leucine-rich repeat-containing G-protein coupled receptor 5 (LGR5) level in human pituitary adenomas and the role of LGR5 in the development of human pituitary adenomas. Methods: Immunohistochemistry is performed to determine the expression of LGR5 in pituitary adenomas and normal pituitaries. LGR5 expression level is determined by the criteria as follows. The one-way analysis of variance (ANOVA) was used to evaluate any significant differences of LGR5 among individual groups. The correlation between expression and the other clinical factors were evaluated by using the Mann-Whitney test and one-way ANOVA. Results: LGR5 is significantly overexpressed in pituitary adenomas compared to normal pituitaries. Conclusion: The overexpression of LGR5 may facilitate the growth of these tumors. Potentially, the finding in the study could be exploited to develop innovative molecular targeted diagnosis and treatment for human pituitary adenomas.
