Throughout my Ph.D., I explored the therapeutic applications of isolated mitochondria in various metabolic disorders, including diabetes, non-alcoholic fatty liver disease, CCl4-induced liver injury, and Alzheimer's disease, utilizing Wistar rats and Swiss albino mice as animal models. In my research, I independently conducted a comprehensive array of laboratory experiments, primarily in biochemistry, evaluating oxidative stress parameters such as SOD (superoxide dismutase), CAT (catalase), GSH (glutathione reductase), MDA (malondialdehyde-lipid peroxidation), NO (nitric oxide), and Total Protein, along with assessing mitochondrial enzyme complex activities. Additionally, I extensively employed essential molecular biology techniques such as RT-PCR, RNA isolation from animal tissues, cDNA preparation, mitochondria isolation, mtDNA isolation, and mtDNA copy number determination, often using gel electrophoresis for analysis. Furthermore, I delved into evaluating the impact of mitochondria transplantation on vital physiological parameters, including blood glucose levels, insulin tolerance, oral glucose tolerance, body weight, BMI, waist circumference, blood pressure, total cholesterol, and lipid profiling. My research also included investigating inflammatory markers like IL-6 and NFkB and exploring bioenergetics and mitochondria biogenesis units, specifically ATP and PGC1 alpha. During my studies, I synthesized nanoparticles such as Graphene quantum dots and superparamagnetic iron oxide, applying chemical techniques to track intravenously transplanted mitochondria in diabetic rats and analyze their biodistribution within the tissues. I gained proficiency in various characterization techniques to track intravenously transplanted mitochondria in diabetic rats and analyze them, using SEM (scanning electron microscopy), TEM (transmission electron microscopy), UV-Vis spectroscopy, FT-IR spectroscopy, photoluminescence spectroscopy, and X-ray diffraction for thorough analysis. Moreover, my work involved the study of diverse cell lines such as HepG2 (hepatic cells), U87MG (neuronal cells), A549 (sarcoma cells), and THP1 (human leukemia monocytic cells). I developed expertise in their passaging and subculturing while observing and analyzing morphological differences using an inverted microscope. Additionally, I performed staining procedures with trypan blue and mitotracker green, conducted cell counting, and utilized cytotoxicity assays (MTT) to evaluate the effects of different nanoparticles. I was responsible for performing data and statistical analysis and participated in writing papers where results were published. I also actively collaborated with my research supervisor to direct future experiments to find the answers to our research questions, conception, design, and execution to address defined problems and also to maintain clean, organized, and well-stocked laboratory environments. I presented my research findings to scientific and general audiences and published my work in peer-reviewed journals.
