Project description:The objectives of this study encompassed a thorough exploration of the potential implications of protein profiling in hairy roots, specifically focusing on optimizing and enhancing C. asiatica organ cell biofactories. In this pursuit, we categorized established C. asiatica hairy root lines according to their capacity for centelloside production, classifying them into HIGH, MID, or LOW categories. For comparative analysis, wild adventitious (Adv) roots were extracted from in vitro C. asiatica seedlings and cultivated in solid MS medium at 25°C in complete darkness, serving as control specimens. This meticulous, label-free proteomic analysis enabled the successful identification of several proteins. Our research substantially builds upon and extends the findings presented by Alcalde et al. (2022) (DOI: 10.3389/fpls.2022.1001023). In their study, distinctive morphological and metabolic variations were noted among different C. asiatica hairy root lines. Such differences are presumably attributable to the random incorporation of a selective set of genes from the T-DNA, with particular emphasis on the rol and aux genes.

Project description:Centella asiatica is an important medicinal plant with a wide range of bioactivities associated with its secondary metabolites. Using two extraction procedures, metabolomic approaches were used to investigate changes in the metabolome of C. asiatica cells treated with exogenous MeJA. GC–MS and LC–MS platforms were employed for semi-targeted and untargeted analyses, respectively. Multivariate data analyses indicated concentration-dependent changes in the metabolite profiles, indicative of the cellular response to MeJA. Annotation of biomarkers correlated with the treatment indicate differential responses in flavonoid-, phenylpropanoid (cinnamates)- and terpenoid pathways and changes in fatty acid profiles. MeJA treatment triggered the accumulation of bicyclic sesquiterpenoids (aristolochene, deoxy-capsidiol, 15-hydroxysolavetivone, solavetivone, 3-hydroxylubimin) and a tricyclic sesquiterpenoid (phytuberin), indicating the stimulatory effect of MeJA on this branch of the terpenoid pathways. In contrast, flavonoids were mostly negatively correlated with the treatment. The presence of the sesquiterpenoids in MeJA-elicited cells and other tentatively identified metabolites (abscisic acid, fatty acids, phytosterols and metabolites of shikimate–phenylpropanoid pathways) indicates that the changes in the metabolome are associated with a defensive function in response to elicitation by MeJA, rather than just the amplification of existing terpene pathways. These results provide a detailed and comprehensive picture of metabolic changes occurring in C. asiatica cells in response to MeJA elicitation and contribute to the understanding of flexible and controllable aspects of metabolic manipulation.

Project description:Leaves of Centella asiatica (Centella) were analysed for their triterpene composition and bioactivity such as collagen enhancement, antioxidant, anticellulite and UV protection capacity properties. Triterpenes of Centella were measured using HPLC-PAD on an Excil ODS 5 mm (C18) column for the simultaneous determination of asiatic acid, madecassic acid, asiaticoside and madecassoside. Centella was found to contain significant amounts of madecassoside (3.10 ± 4.58 mg/mL) and asiaticoside (1.97 ± 2.65 mg/mL), but was low in asiatic and madecassic acid. The highest collagen synthesis was found at 50 mg/mL of Centella extracts. The antioxidant activity of Centella (84%) was compared to grape seed extract (83%) and Vitamin C (88%). Its lipolytic activity was observed by the release of glycerol (115.9 µmol/L) at 0.02% concentration. Centella extracts exhibited similar UV protection effect to OMC at 10% concentration. In view of these results, the potential application of Centella in food and pharmaceutical industries is now widely open.

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.
