Circulating miR-126 as a Potential Non-invasive Biomarker for Intracranial Aneurysmal Rupture: A Pilot Study.

Aim: Intracranial aneurysms (IAs) are characterized by abnormal dilation and thinning of the cerebral vessels wall, leading to rupture and life-threatening aneurysmal subarachnoid hemorrhage (aSAH) condition. This dictates the need to find new biomarkers that predict the presence of IAs and the risk of their rupture. The aim of this study was to measure circulating miR-126 at various time points post-aSAH to identify the timing of peak levels.

Differential non-coding RNAs expression profiles of invasive and non-invasive pituitary adenomas.

Background: Pituitary adenoma (PA) accounts for 10-15% of all intracranial neoplasms. Despite their benign nature, PA often shows invasive growth. MicroRNAs (miRNAs) and long non-coding RNAs (lncRNAs) are a class of non-coding RNAs that play important roles in PA initiation and progression.
