Project description:Mucuna pruriens extract MPE pretreatment may have a direct protective effect on heart (other than immunological neutralization of the venom neurotoxin and phospholipase A2 by the anti-MPE antibodies) that renders the heart more resistant to the toxic action of the venom The direct protective effect probably involves functional changes to the cardiac tissue that enable the heart to resist the reduction of contractility and rate induced by the cobra venom.To explore the possibility of the direct action of MPE pretreatment on heart and to understand the molecular events involved in the protection of MPE pretreatment against the lethal action of Naja sputatrix venom, gene expression studies were carried out using microarray analysis.
Project description:The venom proteomes of three medically important Nigerian Elapidae snakes Naja haje, Naja katiensis and Naja nigricollis was studied using Hydrophilic Interaction Liquid Chromatography (HILIC) coupled with LC-MS/MS analysis. Peptides/Proteins were identified and characterised using the SEQUEST and X!Tandem algorithms incorporated on to the Scaffold proteome software version 4.10.0. The Nigerian elapid species studied displayed about 70% similarity in composition of their venoms.
Project description:Bites by the Indian spectacled cobra (Naja naja) are widely reported across the Indian subcontinent, with an associated high rate of mortality and morbidity. In western India (WI), the numbers of reported incidents of cobra envenomation are significantly higher than the other snake bites. In this study the venom proteome of WINn was deciphered for the first time using tandem mass spectroscopy analysis.
Project description:Venoms of Naja mossambica and Naja nigricincta nigricincta were analysed in order to identify the proteins. Samples were run on SDS-PAGE gel or analysed without digestion.
