Gene-to-metabolite network for biosynthesis of lignans in MeJA-elicited Isatis indigotica hairy root cultures.

Root and leaf tissue of Isatis indigotica shows notable anti-viral efficacy, and are widely used as "Banlangen" and "Daqingye" in traditional Chinese medicine. The plants' pharmacological activity is attributed to phenylpropanoids, especially a group of lignan metabolites. However, the biosynthesis of lignans in I. indigotica remains opaque. This study describes the discovery and analysis of biosynthetic genes and AP2/ERF-type transcription factors involved in lignan biosynthesis in I. indigotica. MeJA treatment revealed differential expression of three genes involved in phenylpropanoid backbone biosynthesis (IiPAL, IiC4H, Ii4CL), five genes involved in lignan biosynthesis (IiCAD, IiC3H, IiCCR, IiDIR, and IiPLR), and 112 putative AP2/ERF transcription factors. In addition, four intermediates of lariciresinol biosynthesis were found to be induced. Based on these results, a canonical correlation analysis using Pearson's correlation coefficient was performed to construct gene-to-metabolite networks and identify putative key genes and rate-limiting reactions in lignan biosynthesis. Over-expression of IiC3H, identified as a key pathway gene, was used for metabolic engineering of I. indigotica hairy roots, and resulted in an increase in lariciresinol production. These findings illustrate the utility of canonical correlation analysis for the discovery and metabolic engineering of key metabolic genes in plants

In vitro antioxidant activities and anti-proliferative properties of the functional herb Abrus cantoniensis and its main alkaloid abrine

Abrus cantoniensis is a common and popular vegetative food consumed as beverage, soup and folk medicine in the tropical and subtropical areas of Asia. It has been claimed valuable for cleansing toxicants in the liver. However, the functional effects of A. cantoniensis have not yet been scientifically explored. This study comprehensively evaluated the in vitro antioxidant and anti-proliferative capacities of the herbal extract and the main alkaloid abrine. Abrine was qualitatively and quantitatively determined in methanol extract (ME) using HPLC-DAD and LC-MS/MS. The results showed that ME, ethyl acetate fraction (EF) and abrine exhibited comparable ABTS radical cation scavenging activities and reducing power to two commercial antioxidants (BHT and Trolox). The EF exerted strong cellular antioxidant activity and selective cytotoxicity against three cancer cell lines in a dose-dependent manner. Biological

Awareness of adverse drug reactions reporting among doctors in a tertiary care centre

Background: Adverse drug reactions (ADR) are more commonly observed during treatment course in a substantial number of patients. Though we have a functioning pharmacovigilance programme in India, we have only fewer number of adverse drug reactions being reported indicating lack of awareness, the unsure attitude and reluctance in reporting adverse drug reactions.Methods: We conducted a cross sectional pretested questionnaire based study for a period of six months. 600 questionnaires were distributed. 521 responded back to the questionnaire of which 29.6% were interns, 56.8% were junior residents, 5.2% doctors were senior residents, and 8.4% were Assistant professors. Awareness on ADR reporting, ADRs encountered in practice, common causative drugs for ADR, and awareness on the functions of Pharmacovigilance programme of India were assessed.Results: 44.9% were not aware of the pharmacovigilance programme; 59.5% of the study population were not aware of the voluntary reporting of ADRs. 100% of the doctors who participated actively in the study responded that have not reported any ADR so far under pharmacovigilance programme of India. 88.1% of the doctors who participated in the study were willing to undergo a training on ADR reporting and pharmacovigilance.Conclusions: This study concludes that serious measures have to be taken to educate the doctors on ADR reporting and pharmacovigilance. By means of involving pharmacovigilance as a part of the undergraduate programme and by organising regular workshops, group discussion and continuous medical education, we can improve the awareness among doctors regarding ADR reporting and pharmacovigilance

Improving effect of Platycodin D on ethanol-induced fatty liver via Keape-NRF2-are signal path

No Abstract

Dose-related liver injury of Geniposide associated with the alteration in bile acid synthesis and transportation.

Fructus Gardenia (FG), containing the major active constituent Geniposide, is widely used in China for medicinal purposes. Currently, clinical reports of FG toxicity have not been published, however, animal studies have shown FG or Geniposide can cause hepatotoxicity in rats. We investigated Geniposide-induced hepatic injury in male Sprague-Dawley rats after 3-day intragastric administration of 100 mg/kg or 300 mg/kg Geniposide. Changes in hepatic histomorphology, serum liver enzyme, serum and hepatic bile acid profiles, and hepatic bile acid synthesis and transportation gene expression were measured. The 300 mg/kg Geniposide caused liver injury evidenced by pathological changes and increases in serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and γ-glutamytransferase (γ-GT). While liver, but not sera, total bile acids (TBAs) were increased 75% by this dose, dominated by increases in taurine-conjugated bile acids (t-CBAs). The 300 mg/kg Geniposide also down-regulated expression of Farnesoid X receptor (FXR), small heterodimer partner (SHP) and bile salt export pump (BSEP). In conclusion, 300 mg/kg Geniposide can induce liver injury with associated changes in bile acid regulating genes, leading to an accumulation of taurine conjugates in the rat liver. Taurocholic acid (TCA), taurochenodeoxycholic acid (TCDCA) as well as tauro-α-muricholic acid (T-α-MCA) are potential markers for Geniposide-induced hepatic damage
