Research History
(2015-present): As part of a research line at biotechnology lab ofRazi Vaccine and Serum Research Institute we are studying the epitope mapping of snake venom using monoclonal antibodies.
(2012-2013):In my postdoctoral researches at St. John’s University I studied the interaction network in membranechannel-forming proteins TRPP/PKD complexes. These proteins were previously identified as the disease genes causing autosomal dominant polycystic kidney disease (ADPKD). I have studied the roles of extracellular loops in these proteins for the assembly and function of TRPP/PKD complexes using co-IP, IF and electrophysiological assays. I wasalso involved in other project which studied the effect of Edaravonein neuronal cellprotection in response to oxidative stress. Weperformed comparative two-dimensional gel electrophoresis (2DE) based proteomic analyses on SH-SY5Y neuroblastoma cells exposed to oxidative stress and in combinationwith Edaravone. We showed that Edaravone can reverse the cytotoxic effects of H2O2 through itsspecific mechanism. We observed that oxidative stress changes metabolic pathways and cytoskeletalintegrity. Edaravone seems to reverse the H2O2-mediated effects at both the cellular and protein level viainduction of Peroxiredoxin-2.
(2011-2012): In my former postdoctoral research at Lehman College we performed a comprehensive study on the regulation of ExoR protein expression and its interaction with ExoS protein, the membrane-bound sensor of the ExoS/ChvI two-component regulatory system by using different site directed mutagenesis. In SinorhizobiummelilotiExoR–ExoS/ChvIsignallingpathway regulate the biosynthesis of succinoglycan, an exopolysaccharide important for host invasion. We are in the process of filing a U.S. patent about ExoR/ExoS/ChvI sensing pathway involved in the symbiosis.
(2007-2011):In my PhD studies at INBIOTEC (a Spanish biotech company collaborating with University of Leon), I worked on different projects. My main study was characterization of gamma-butyrolacone receptors in tacrolimus producer strains S. tsukubaensisand S. tacrolimicus and analysis of their autoregulatory function. Using REDIRECT technology I succeed to generate several deletions in the regulatory genes involved in gamma-butyrolactone pathway. Then I analyzed the impact of alteration of these targets on tacrolimus production (using HPLC analysis) and morphogenesis (using electronic microscopy). The expression and purification of gamma-butyrolactone receptor proteins using GST gene fusion system and FPLC and analysis of their DNA binding activity using EMSA and Footprinting assays were other part of my study.
I also optimized the fermentation conditions for tacrolimus production and growth rate in S. tsukubaensisin terms of carbon, nitrogen and calcium sources as well as pH. As a result the tacrolimus production in the optimized condition increase up to four fold. In addition I was involved in the genome sequencing project of S. tsukubaensis where I analyzed the physical map of S. tsukubaensis genome using PFGE electrophoresis. Moreover we compared the secretomic maps of three Penicilliumchrysogenum strains (non-industrial and industrial strains with different levels of penicillin production) using 2DE-MS/MS. Our purpose was to develop a better insight into the biochemical pathways involved in penicillin production.
(2004-2006):In my M.Sc. research we performedthe molecular analysis of the clavulanic acid regulatory gene (claR gene) isolated from an Iranian strain Streptomyces clavuligerus PTCC 1709. Furthermore we studied the relationship between the length of CA repeats in the EGFR gene and the risk of breast cancer incidence and prognosis. At the same time we succeeded to develop a novel STR based molecular diagnosis of Charcot-Marie-Tooth neuropathies.
