RESEARCH ACTIVITY AND SCIENTIFIC ACHIEVEMENTS:
Dr. Federova came to the Medical College of Ohio in 2003 as a research assistant professor in the laboratory of Dr. Shapiro and Dr. Malhotra to begin a pilot project "Proteomic study of kidneys from partially nephrectomized rats immunized against cardiotonic steroid marinobufagenin." She found that immunization against marinobufagenin attenuated the severity of fibrosis and oxidative stress seen after partial nephrectomy. This observation promoted a large investigation into marinobufagenin role in the development of renal fibrosis. They demonstrated that marinobufagenin induced periglomerular, perivascular and interstitial fibrosis and provided evidence that marinobufagenin triggers epithelial to mesenchymal transition through up-regulation and subcellular relocation of the transcription factor Snail in kidneys and renal epithelial cell line. Recently she analyzed the Snail expression in pathologies associated with elevated levels of marinobufagenin, such as preeclampsia and cardiac fibrosis. The expression of the transcription factor Snail in human and rat placentas was down-regulated by 30-50% in preeclampsia.She also found that the transcription factor Snail is specifically localized in rat cardiac and renal autonomic nerves and its level remained unchanged with marinobufagenin infusion.

Since 2007 Dr. Fedorova has worked with Dr. Najjar, the Director of the Center of Endocrine and Diabetic Research at the University of Toledo, Health Science Campus. She particularly helped Dr. Najjar in the study of apoptosis, inflammation and fibrosis in the liver of mice with genetically altered insulin clearance.

Dr. Federova also teaches laboratory work to graduate, medical, and summer students and residents in Dr. Shapiro and Dr. Malhotra's laboratory. She also consults graduate students from Dr. Najjar's laboratory for the immunohistochemical analysis of metastasis development and epithelial to mesenchymal transition.

Before Dr. Federova joined the University of Toledo, she worked at Tuft University in Boston. She started there in 1999 as a research assistant in the Transgenic Core Research Laboratory under supervision of Dr. Janis Lem. Upon completion of her Ph.D. thesis. In 2001 she transferred to the Vision Research Laboratory of Dr. Elizabeth Fini and began a pilot project "Proteomic analysis of normal and keratoconus corneas" as a research fellow. At that time she received a post-doctoral fellow grant support from Fight for Sight To Prevent Blindness America.
