From Transcriptomics to Treatment in Inherited Optic Neuropathies

Area of Science:

• Neuroscience
• Genetics
• Ophthalmology

Background:

• Inherited optic neuropathies, including Leber Hereditary Optic Neuropathy (LHON) and Dominant Optic Atrophy (DOA), are monogenetic diseases.
• These conditions share a common pathway of mitochondrial dysfunction leading to retinal ganglion cell (RGC) death and vision loss.
• They serve as models for studying neurodegenerative diseases like Glaucoma and Parkinson disease.

Purpose of the Study:

• To discuss the significance of inherited optic neuropathies.
• To explore the application of transcriptomic techniques in developing novel therapies.
• To identify potential therapeutic targets for mutation-independent, neuroprotective treatments.

Main Methods:

• Review and discussion of existing research on inherited optic neuropathies.
• Analysis of transcriptomic data from affected cells using techniques like RNA-sequencing.
• Exploration of cellular and animal models of LHON and DOA.

Main Results:

• Matured cellular and animal models of LHON and DOA are available.
• Transcriptomic techniques enable detailed analysis of affected cells.
• This confluence presents opportunities for identifying novel pathogenic players.

Conclusions:

• Inherited optic neuropathies are crucial models for understanding mitochondrial dysfunction in neurodegeneration.
• Transcriptomic analysis is a powerful tool for discovering new therapeutic targets.
• The study highlights the potential for developing mutation-independent, neuroprotective therapies for vision loss.
