As a faculty member in the Department of Pathobiology (since October 2000), I established the extramurally funded programs in the areas of Directed Molecular Evolution and Targeting. The research programs included:

  • Construction of new phage vectors and diverse phage display libraries.
  • Selection of tumor-targeting phage probes and their use for diagnosis and targeted gene and drug delivery and treatment of cancer diseases.
  • Selection and evolutionary improvement of phage-derived probes against Salmonella typhimurium, Bacillus anthracis and other food and environmental threat agents.
  • Genetically engineered self-assembling of bio-selective layers in biosensors for detection of microbial and toxic threat agents.
  • Optimization of monitoring and detection of Salmonella typhimurium, Bacillus anthracis and other threat agents by phage-derived probes immobilized on the surface of biosensors.

Work in Progress

My current research program is focused on:

  • Monitoring and detection of biological threats
  • Diagnosis of infectious diseases and cancer
  • Targeting of tumor cells

To attack these problems, I employ methods of Directed Molecular Evolution, Multivalent Phage Display and Phage Nanobiotechnology that have been developed by my group. This program is a continuation of my previous study of the Combinatorial Biochemistry and Landscape phage Libraries.

Academic Training

I began my research activity in 1969 as a student at the Moscow State University in the Laboratory of Phosphor-organic Chemistry headed by Prof. E.E. Nifant'ev. My goal was to synthesize molecules that could normally operate in living cells. In my master diploma project, I developed new phosphorylation agents for synthesis of DNA, glycosyl-phosphates and other important natural compounds. After graduating from the University in 1972, I continued my research as a Ph.D. student in the Institute of Organic Chemistry, USSR Academy of Sciences, Moscow. My supervisors were Academician N.K. Kochetkov and Prof. V.N. Shibaev — internationally recognized leaders in DNA and carbohydrate chemistry. In my Ph.D. dissertation project, I studied biosynthesis of Salmonella antigens using synthetic analogs of thymidine-diphosphate-rhamnose. Results of this study were presented in 7 papers.

Since 1977, I focused my scientific interests on directed molecular evolution, synthesis and designed reconstruction of DNA, phage display, protein drug design, and diagnostics.

Site-Directed Mutagenesis

The 70th revolutionized biotechnology by inventing recombinant DNA. Thus, since 1977, after establishing my laboratory in Scientific Association “Vector”, Novosibirsk (USSR), I focused my scientific interests on directed molecular evolution, designed reconstruction of DNA, phage display, protein drug design, and diagnostics. As result, my group developed first analogues of oligonucleotides inducing site-directed mutations in vitro and in vivo

We inventored a method allowing to introduce mutations localized in the operator-promotor regions of genome:

Multivalent Phage Display

In 1985, George Smith published in Science his revolutionary paper describing cloning of foreign gene as a fusion to the Minor coat protein pIII of the filamentous phage fd (Times Cited: 1,971). Later this technique was named “Phage Display”:

After Smith’s publication, I was fascinated to learn if filamentous phage can tolerate multiple mutations and insertions of foreign peptides into the Major coat protein pVIII, 2,700 copies of which cover the viral DNA to form viral capsid. It was commonly believed that pVIII is extremely conservative and cannot be modified. Using methods of site-directed mutagenesis, we constructed vectors that allowed us to check this hypothesis. Our efforts resulted in construction of the first recombinant phages with the pVIII protein fused to foreign peptides:

Phage Nanobiotechnology for Detection of Threat Agents

These preliminary results inspired me to study filamentous phage with pVIII fusions (later named “landscape phage”) as novel engineered nanomaterials for design of synthetic vaccines, diagnostics, detectors and drug/gene delivery vectors:

Cancer Targeted Nanomedicines

My current interest lies in the area of cancer-targeted drug development. We first demonstrated that cancer-targeted major coat proteins isolated from preselected landscape phages can be complexed with liposomes, micelles, nanotubes and siRNA, increasing their therapeutic effect:
