Bacosides Encapsulated in Lactoferrin Conjugated PEG-PLA-PCL-OH Based Polymersomes Act as Epigenetic Modulator in Chemically Induced Amnesia. Neurochem Res. 2020 Jan 20;: Authors: Goyal K, Konar A, Kumar A, Koul V Abstract The present study demonstrates the epigenetic mechanisms underlying the effect of Bacoside rich extract of Bacopa monniera-a nootropic herb, on scopolamine treated amnesic mice conferred via chromatin modifying enzymes. The focus of the work was to elucidate the modulation of the chromatin modifying enzymes: DNMT1, DNMT3a, DNMT3b, HDAC2, HDAC5 and CPB in scopolamine induced amnesic mice after treatment with bacoside rich extract of Bacopa monniera (BA) and BA encapsulated in lactoferrin conjugated PEG-PLA-PCL-OH based polymersomes (BAN). We observed remarkable difference between the results obtained after the treatment with BA and BAN. Interestingly BAN was found to be more efficient in downregulating DNA methylation and histone chain deacetylation. Scopolamine treatment showed up-regulation of DNMT1 expression in qRT-PCR by 3.14-fold as compared to the control, which was considerably decreased by 1.5-fold after treatment with BA and remarkably decreased 0.11-fold by BAN treatment. Scopolamine treatment up-regulated the expression of DNMT3a by 1.6-fold while for DNMT3b by 3.13-fold. In DNMT3a and DNMT3b the fold change decreased to 0.64 and 0.76 after BA treatment, whereas the BAN treatment further down-regulated t...
