15-Lox-1 expression level in pituitary adenomas. The expression level of 15-Lox-1 was evaluated in tumor and normal tissues of pituitary with different adenoma types. The 15-Lox-1 expression level was increased in pituitary adenoma (a), non-functional pituitary adenoma (b), different types of functional pituitary adenoma (c), macroadenoma (d) and invasive (e) tumor tissues. The Statistical differences between groups is shown as asterisk (* = P < 0.05, ** = P < 0.01,*** = P < 0.001)
