Pituitary adenomas (PAs) are common cranial tumors that affect the quality of life in patients. Early detection of PA is beneficial for avoiding clinical complications of this disease and increasing the quality of life. Noncoding RNAs, including long noncoding RNA, miRNA and circRNA, regulate protein expression, mostly by inhibiting the translation process. Studies have shown that dysregulation of noncoding RNAs is associated with PA. Hence understanding the expression pattern of noncoding RNAs can be considered a promising method for developing biomarkers. This article reviews data on the expression pattern of dysregulated noncoding RNAs involved in PA. Possible molecular mechanisms by which the dysregulated noncoding RNA could possibly induce PA are also described.

Lay abstract Pituitary adenomas (PA) are benign, slow-growing tumors of the pituitary gland. The sooner the tumor is diagnosed, the sooner can the patient be treated with medication. The early detection of this disease can reduce the need for surgery to remove the tumor. Noncoding RNAs are small molecules that regulate the functions and behavior of different cells. When the intracellular or extracellular concentration of these small molecules is altered, the functions and behavior of cells and tissues can be affected and changed. Quantifying and analyzing these molecules is a promising tool for the early detection of different diseases, including PA. This article reviews alterations in these small molecules and the relationship between these alterations and the incidence of PA.
