The Role of microRNAs Related to Apoptosis for -Methyl-d-Aspartic Acid-Induced Neuronal Cell Death in the Murine Retina.

Glaucoma is one of the leading causes of acquired blindness and characterized by retinal ganglion cell (RGC) death. MicroRNAs are small noncoding RNAs that degrade their target mRNAs. Apoptosis is one of the common mechanisms leading to neuronal death in many neurodegenerative diseases, including glaucoma.

GYY4137, an Extended-Release Hydrogen Sulfide Donor, Reduces NMDA-Induced Neuronal Injury in the Murine Retina.

We previously reported that systemic administration with sodium hydrogen sulfide, a rapid-release donor compound of hydrogen sulfide (HS), protected retinal neurons against N-methyl-D-aspartic acid (NMDA)-induced injury. For clinical application of HS donors for retinal neurodegeneration, topical administration with an extended-release donor compound will be better. In the present study, we histologically investigated whether GYY4137, an extended-release hydrogen sulfide donor, had a protective effect on NMDA-induced retinal injury in the mice in vivo.
