Plasma microRNA signature associated with retinopathy in patients with type 2 diabetes.

Diabetic retinopathy (DR) is a leading cause of vision loss and disability. Effective management of DR depends on prompt treatment and would benefit from biomarkers for screening and pre-symptomatic detection of retinopathy in diabetic patients. MicroRNAs (miRNAs) are post-transcriptional regulators of gene expression which are released in the bloodstream and may serve as biomarkers.

Clobetasol and Halcinonide Act as Smoothened Agonists to Promote Myelin Gene Expression and RxRγ Receptor Activation.

One of the causes of permanent disability in chronic multiple sclerosis patients is the inability of oligodendrocyte progenitor cells (OPCs) to terminate their maturation program at lesions. To identify key regulators of myelin gene expression acting at the last stages of OPC maturation we developed a drug repositioning strategy based on the mouse immortalized oligodendrocyte (OL) cell line Oli-neu brought to the premyelination stage by stably expressing a key factor regulating the last stages of OL maturation. The Prestwick Chemical Library of 1,200 FDA-approved compound(s) was repositioned at three dosages based on the induction of Myelin Basic Protein (MBP) expression.

MicroRNA profiling in migraine without aura: pilot study.

Background And Purpose: MicroRNAs (miRNAs) are short, non-coding RNAs whose deregulation has been shown in several human diseases, including pain states and diseases associated with increased cardiovascular (CV) risk. This study aimed at identifying differentially expressed circulating miRNAs in patients with 'migraine without aura' (MO), a pain condition whose link with CV risk remains debated.

Methods: Fifteen female MO patients and 13 matching healthy controls underwent a circulating microRNA expression profiling.

Plasma exosome microRNA profiling unravels a new potential modulator of adiponectin pathway in diabetes: effect of glycemic control.

Context: Type 2 diabetes is a chronic disease characterized by inadequate β-cell response to the progressive insulin resistance. MicroRNAs (miRNAs) are short, endogenous, noncoding RNAs representing a class of powerful gene expression modulators. Previous population studies observed a modulation of circulating miRNAs in diabetic patients; however, few data are presently available on miRNA modulation in diabetic patients naïve to pharmacological treatment as well as the effect of glycemic control on this.

Overexpression of microRNA-145 in atherosclerotic plaques from hypertensive patients.

Background: MicroRNAs (miRNAs) are endogenous, non-coding, short, single-stranded RNAs and represent a new class of gene regulators. Recent evidence supports a role for miRNAs in cardiovascular pathophysiology and atherosclerosis development. We have previously demonstrated that miR-145 is widely expressed in human atherosclerotic lesions and its downregulation has been correlated with vascular smooth muscle cell dedifferentiation, a cardinal step in the development of atherosclerosis.
