Project description:Ayurvedic drug formulations Bacopa monnieri and Centella asiatica are known to have neuroprotective effects. These have been traditionally used in the treatment of Alzhemeir’s disease, and other neurological deficits. Using pan neuronal Aβ42 model of Drosophila melanogaster, a mass spectrometry based quantitative proteomic analysis platform was used to generate the data on proteins altered in response to the Aβ42 toxicity and restoration of altered proteins by consumption of aqueous extracts of two Ayurvedic drug formulations Bacopa monnieri and Centella asiatica aqueous extract. Quantitative proteomic analysis resulted in 0.67 million mass spectra corresponding to 2,59,168 peptide-spectrum matches (PSM) mapping to 24,305 non- redundant peptides corresponding to 11,480 Drosophila melanogaster proteins. Proteins were filtered for >3 PSMs, resulting in 9,540 proteins. Flies expressing Aβ42 significantly altered 517 proteins which were involved in maintaining essential neuronal functions. Supplementing flies with Bacopa monnieri or Centella asiatica extract commonly rescued 224 proteins from Aβ42 toxicity, moreover, extract supplemented group significantly altered proteins which were additionally supporting neuronal maintenance in flies with Aβ42 stress.
