GH1 and pituitary gland adenoma: In1-ghrelin expression levels correlated with those of MBOAT4 in GH-omas, ACTH-omas, and NFPAs, but not in normal pituitaries (no correlation analysis were performed in PRL-omas due to insufficient number of samples), which may suggest that In1-ghrelin could be functionally linked with MBOAT4 in pituitary adenomas.
