Supplementary MaterialsDataSheet_1. The modulations of the transcript levels were then subjected to bio-informatics analyses using established software. Treatment with ISO downregulated 1,129 genes and upregulated 204 others. Pre-treatment with the TA bark extracts markedly restored that expression pattern with only 97 genes upregulated and 85 genes downregulated. The TA alone group had only 88 upregulated and 26 downregulated genes. The overall profile of expression in ISO + TA and TA alone groups closely matched with the control group. The genes that were modulated included those involved in metabolism, activation of receptors and cell signaling, and cardiovascular and other diseases. Networks associated with those genes included those involved in angiogenesis, extracellular matrix organization, integrin binding, inflammation, drug metabolism, redox metabolism, oxidative phosphorylation, and organization of myofibril. Overlaying LY2603618 (IC-83) of the networks in ISO and ISO_TA group showed that those activated in ISO group were mostly absent in ISO_TA and TA group, suggesting a global effect of the TA extracts. LY2603618 (IC-83) This study CXCR3 for the first time reveals that LY2603618 (IC-83) LY2603618 (IC-83) TA partially or completely restores the gene regulatory network perturbed by ISO treatment in rat heart; signifying its LY2603618 (IC-83) efficacy in checking ISO-induced cardiac hypertrophy. (Roxb.) (TA) has been in use as a cardioprotective agent for centuries by Indian system of medicine (Ayurveda) (Mongalo et al., 2016; Amalraj and Gopi, 2017). Studies done in our laboratory have shown that the bark extract of TA has beneficial effects in experimentally induced myocardial ischemia, hypertrophy, fibrosis, and other cardiovascular disorders. It boosts anti-oxidant activities, prevents fibrosis, protects against ischemia reperfusion injury and has anti-hypotensive effects (Kumar et al., 2009; Maulik and Katiyar, 2010; Maulik et al., 2016; Meghwani et al., 2017). In a recent study, arjunolic acid, one of the constituents of the aqueous TA extract, was shown to ameliorate cardiac fibrosis by inhibiting TGF- signaling (Bansal et al., 2017). Earlier, we had used limited proteomic approach (2D gel based) to establish that TA bark extract substantially modulates the rat cardiac proteome under adrenergic (ISO) stress (Kumar et al., 2017). To further establish the efficacy of TA extract we now have used more robust approach that is global transcriptomic analyses to establish the efficacy of TA extract in modulating various biological pathways and gene networks targeted by ISO. We demonstrate that TA extract reverses ISO induced reprogramming of gene expression in rat heart. Our study for the first time convincingly establishes that the effects of TA are far wider than that is expected for today’s drug generally having an individual target. Components and Methods Pet Tests and Ethics Declaration Lab bred Wistar male rats (150C200 g, 10C12 weeks) had been employed for the analysis and taken care of under standard lab conditions (temperatures; 25C 2C, comparative moisture; 50% 15% and 12-h dark/12-h light period). The scholarly research was carried out relative to the Institutional Pet Ethics Committee, All India Institute of Medical Sciences, New Delhi, India. All pet treatment and experimental protocols had been performed in conformity with the Country wide Institutes of Wellness (NIH) Recommendations for the Treatment and Usage of Laboratory Pets (NIH Publication no. 85723, modified 1996).
