Electrophysiological and Behavioral studies in mouse models of cortico-striatal plasticity is the outcome of my project. Generated cortico-striatal plasticity in mice by injecting them with psycostimulants such as cocaine and amphetamine. I focused my studies on gestational effect of psycostimulants, which showed symptom’s like Parkinson’s disease. Psycostimulants are known to increase the dopamine neurotransmitter levels in-vivo, but the gestational effect is unknown. The mechanism of synaptic plasticity is studied in striatal slices and dissociated striatal cells by patch clamping experiments. Patched cells were characterized by biocytin immunohistochemistry. Patch clamping data is correlated with behavior and multiphoton imaging studies done in those mice. I observed very interesting differences in synaptic plasticity at different age groups of mice and also observed significant differences in male and female mice. These studies help’s in understanding the effects of alterations made in dopaminergic neurotransmission in neurons of striatum at different age groups and sex of mice. Impaired dopaminergic neurotransmission in striatum is the leading cause for various neurological disorders hence this research is very important to find cures for movement and learning disorders which include both neurodegenerative and neurodevelopmental diseases.

Identification of possible role of microchimeric cells in Human and Mouse models of Lupus and Multiple Sclerosis is the outcome of my project. Microchimeric cells are stem cells which pass from mother to offspring during pregnancy. The hypothesis is that these cells loose tolerance to body immune system due to some unknown reason and triggers autoimmune diseases such as lupus and multiple sclerosis. This is a novel field of research and needs lots of studies to conclude anything. Lupus is devastating autoimmune blood disorder with lot of damaging effects on brain. Multiple sclerosis is also an autoimmune brain disorder. Interestingly, immunohistochemical, DNA Fluorescent Insitu Hybridization and quantitative PCR studies done on the postmortem human brain tissue, lymphocytes from patient blood samples and mouse tissue showed that there is an increase in microchimeric cells in these diseases. In order to understand the gene expression in microchimeric cells in disease verses normal conditions, I isolated microchimeric cells using LASER capture microdissection and studied gene expression pattern in them using microarray experiments and quantitative RT-PCR technique. I still need to repeat these experiments many times to reach to a conclusion. This is a very important research because if microchimeric cells are triggering autoimmune diseases then we can develop strategies to make them tolerate body immune system or specifically eliminate them.

Active and inactive Neurotransmitter Nitric oxide isoform expression in neurons and Adenocarcinoma is the outcome of my project. Nitric oxide is a gaseous neurotransmitter extensively studied in gut. It is known to relax smooth muscle cells in gut to open the pyloric sphincter for passage of food from one part of stomach to next part. The function of nitric oxide in adeno- carcinoma and striatum part of brain, specially regulating the dopaminergic neurotransmission is unknown. I focused my research in identifying novel active isoforms of neuronal nitric oxide synthase enzyme expressed in nerve terminals by using western blot and immunoprecipitation in gut which I will compare with the ones expressed in brain during normal and pathological conditions. This type of research is very important because brain disorders severely affect neuronal cells in brain not much to the gastrointestinal neurons. So, if we can find the differences between these neurons, especially protection mechanisms, these can be used to protect brain cells as well.

Role of Polyadenylation in Rett Syndrome is the outcome of my project. Lower levels or mutations in Mecp2 gene in brain causes neurodevelopmental disorder Rett syndrome. Mecp2 protein is expressed primarily by two types of transcripts short transcript and long transcript. Longer transcript has a long 3’ non coding region (3’UTR). Switch from short to long form alters the mRNA stability and subcellular localization in neurons. I identified and quantified these transcripts at various developmental stages in mouse brain by using Northern blot, RT-PCR and quantitative PCR. I also developed a cell culture model for Rett Syndrome and quantified Mecp2 gene and protein levels with development using LASER Scanning Cytometry. Transfected these cells with siRNA (Decoy approach) to knock down Mecp2 expression. Future aim is to knock down 3’UTR and study the effect on neurotransmission in cells. It is a very important research because this will give us an idea that which transcript is actually involved in neurotransmission and which transcript localizes itself or translate protein in nerve terminals.

Human Genetics

Role of dynamin protein and transcriptional factors in Huntington’s disease is the outcome of my project

Huntington’s disease is a neurodegenerative disorder caused due to increase in glutamate

repeats on huntingtin’s gene. Developed a cell culture model for Huntington’s disease by overexpressing huntingtin gene with different number of glutamate repeat’s. The severity of disease depends on increasing number of glutamate repeat’s. I co-transfected these cells with dynamin construct to study the effect of dynamin along with the severity of disease. I found very interesting results which indicate that dynamin protein in involved in mitochondrial fission and fusion, involved in formation of nerve terminals and also involved in internalization of D1 and D2 receptors in neurons which regulate the dopaminergic neurotransmission. Future studies are, to find out how dynamin levels effect neurotransmission in striatum. I also did preliminary studies to see how transcriptional factors affect Huntington’s disease. I made GST and His tag fusion proteins for Sp1 and Huntingtin in bacteria, purified the proteins and studied protein- protein interactions.

Novel slow intermediate free-radicals in Ischemia Reperfusion Injury is the outcome of my project. Free radicals generated during ischemia reperfusion injury causes severe damage to brain cells. I developed a liposomal membrane model to study Ischemia reperfusion injury and also synthesized cobalt complexes to amplify free radical damage. I increased the levels of fast acting radicals by filling the liposome’s with caged cobalt complexes and exposed them to LASER beam. Cobalt complexes released oxygen upon LASER exposure and damaged the membranes by forming free radicals. These radicals were trapped by spin traps and detected by Electron spin resonance spectrometry (ESR). My experiments proved that only oxy, hydroxy and peroxy radicals can be detected by regular ESR machine. It is not possible to detect other (hypothetical) fast generating radicals by using regular ESR machine. A cutting edge Pulsed electron spin resonance spectrometer can be used to detect free radicals generated at nanosecond time scale, may help us in identifying new free radicals. This research is very important because unknown fast acting free radicals damage organ’s during transplantation. This damage limits the time frame of organ transportation from one place to another and also use. We identified these damaging slow intermediate free radical’s as a marker this technology can save many lives.

Education

Ph.D. in Biochemical-Engineering Thesis submitted: Nov 1999 (Indian Institute of Technology, Bombay, India) Degree awarded: May 2000

Used 1-3liter Bioreactor which is also a microbial fermentation sort of combined unique design by me during my Ph.D. as graduate studies. Bacterial fermentation to produce economically important products such as xanthan gum, ascorbic acid, pyocyanin etc. Analyzed these products using chromatographic techniques such as HPLC and GC. To understand the metabolism and molecular mechanism of product formation, expression of Sox RS regulon in presence and absence of Antioxidants and Oxidants were studied. This research is very important because this is the first time we showed the effect of optimum and excess free radicals generated in bacteria on product quality and quantity. This research has lots of applications in industry.

M.S. in Biochemistry, India July 1993-May1995

Summer project done on: “Effects of pesticides on mice”, the results showed that pesticides interfere with electron transport system in mitochondria and generate free radicals. These mice showed symptom’s like Parkinson’s disease. This is a very important study to show how environmental pollutant’s leads to devastating neurological diseases.

B.S. in Biology and Chemistry, India July 1991-June 1993

Research project: “Effects of pesticides on benthic biota” was a voluntary work I did during my spare time to gain some experience in the field of free radical research. Fresh water invertebrate species which are very important to keep a healthy pond ecosystem, showed protein loss and mortality in geographical area’s (Madhya Pradesh) where excessive pesticides were used. Pesticides generated free radicals in these species which formed protein adducts and led to protein loss detected using spectrophotometer. Studies involve survey of vector born diseases due to imbalance of pond ecosystem. Water analysis for various pathological microbes is also done by me.
