Abstract:
Title: Through the Looking Glass: Uncovering the Molecular Mechanisms of Phytochemical Treatment for the Prevention Age-Related Macular Degeneration

Purpose: Age-Related Macular Degeneration (AMD), the primary cause for blindness in people over 65, has no cure. Stopping angiogenesis prevents AMD. Ethnodyne Visio™ (a mixture of phytochemicals: Withaferin A, Gallic Acid, and Bacopaside I) is emerging as a promising preventive for AMD. However, its mechanism of action is unknown.
Hypothesis: Studying the gene network regulated by constituents of Ethnodyne Visio™ will reveal its mechanism of action.
Procedure: Data sets from a systems-level analysis of AMD (GEO2R-GSE85871) was compared with data sets for constituents of Ethnodyne Visio™ to obtain significant (p< 0.05) changes in gene expression and to reveal common impacts of each phytochemical in Ethnodyne Visio™. G: Profiler and STRING were used to reveal the interaction network and molecular functions. A list of transcriptomic (mRNA) variations caused by constituents of Ethnodyne Visio™ was cross-compared with a systems-level analysis of AMD. Altered signaling changes in AP-1 and SMAD transcription factors and epigenetic regulatory miRNAs and histone acetyl-transferase were discovered.
Conclusion: The phytochemical components of Ethnodyne Visio™ may affect the epigenetic miRNA and SWI/SNF complexes, as well as transcriptomic gene regulatory mechanisms.
