Anti-angiogenic properties of microRNA-29a in preclinical ocular models.

Abnormal neovascularization is an important cause of blindness in many ocular diseases, for which the etiology and pathogenic mechanisms remain incompletely understood. Recent studies have revealed the diverse roles of noncoding RNAs in various biological processes and facilitated the research and development of the clinical application of numerous RNA drugs, including microRNAs. Here, we report the antiangiogenic activity of microRNA-29a (miR-29a) in three animal models of ocular neovascularization.

Elevated Plasma Levels of Drebrin in Glaucoma Patients With Neurodegeneration.

Glaucoma is an optic neuropathy characterized by progressive degeneration of retinal ganglion cells (RGCs). Aberrations in several cytoskeletal proteins, such as tau have been implicated in the pathogenesis of neurodegenerative diseases, could be initiating factors in glaucoma progression and occurring prior to axon degeneration. Developmentally regulated brain protein (Drebrin or DBN1) is an evolutionarily conserved actin-binding protein playing a prominent role in neurons and is implicated in neurodegenerative diseases.

Circulating S100A8/A9 Levels Reflect Intraocular Inflammation in Uveitis Patients.

To investigate whether there is an association between circulating S100A8/A9 levels and uveitis activity. A total of 549 plasma samples were collected from uveitis patients and non-uveitic controls. S100A8/A9 plasma levels were elevated in uveitis patients compared to non-uveitic controls ( < 0.
