Department of Pathology and Laboratory Medicine Spring 2015 Seminar Series: Friday, February 6,
Yuriy Alekseyev, Ph.D.
Research Associate Professor of Pathology & Laboratory Medicine
Director, Microarray Resource
Ph.D. 2001, Wayne State University
Yuriy serves as director of BU Microarray Core Resource facility since 2007. Prior to joining BU, Yuriy was a post-doctoral associate with Dr. John Essigmann at MIT where he used animal models to study transcriptional networks affected by a human hepatocarcinogen Aflatoxin B1 and by chemoprevention agents that suppress aflatoxin-induced carcinogenesis.
Yuriy earned a Ph.D. in Biochemistry from the Department of Chemistry at Wayne State University in the laboratory of Dr. Romano, where he studied mechanisms of DNA replication, mutagenesis and repair of carcinogenic lesions. Prior to that he received a M.S. in biotechnology from Moscow Academy of Fine Chemical Technology and worked in Moscow State Scientific Center GNIIGenetica where he studied plant toxins and took part in development of immunotoxins for potential use in cancer therapy and organ transplantation.
Genetic research and technology are developing at a very fast pace. Microarray technology and massively parallel sequencing are widely used to explore the complex biological states that result from the interplay between an organism’s genome sequence and its environment. As a result, these technologies are proving themselves to be a powerful tools for diagnostics. Clinicogenomic approaches based on these technologies are beginning to yield individually tailored therapies for treating cancer and other diseases and the hope is that these types of approaches will soon become a general practice.
The mission of the Boston University Microarray Resource is to provide the investigators with the tools they need to apply the power of genome-wide experimentation to their research topics and to keep them abreast of innovations within this fast changing area. We provide services including sample processing and assistance with data analysis using the Affymetrix platform, which enables rapid, reproducible and accurate microarray analysis on the genome-wide scale. In addition to gene expression analysis the platform makes it possible to perform whole-genome association studies, copy number analysis, targeted genotyping, sequence analysis, studies of gene regulation, DNA methylation, origins of replication, transcription factor binding, alternative splicing, etc. Recently, we introduced a new service: library preparation for Illumina massively parallel sequencing. These technologies have been broadly used by members of the Boston University research community and beyond who are interested in diverse topics including cancer research, infectious disease, immunology, stem cell research and molecular biology: including many who are interested in seeing the results of this research translate into new approaches for patient diagnosis and care.
