  Dr. S. Mohsen Asghari was born in 1978, in Tehran. He was graduated in Professor Hesabi high school in Tehran (1996), received his B.Sc. in Biology-Animal Sciences from Gorgan University of Agricultural Sciences, Gorgan (2000), and his M.Sc. (2003) and Ph.D. (2008) in Biochemistry from Tarbiat Modares University, Tehran, Iran. During M.Sc. and Ph.D., the focus of his studies was on the structure-function relationships of enzymes and rational protein engineering. After a sabbatical in Utrecht University, the Netherlands, he was joined the University of Guilan at 2009 as assistant professor. Dr Asghari was promoted to associate professor of biochemistry in 2017 and, since 2020, he has joined to IBB.

He is teaching enzymology, cell signaling and biochemistry of cancer for M.Sc. and Ph.D. students of IBB, enzymology for Ph.D. students of biotechnology (College of Science), and advanced biochemical engineering for Ph.D. students of biotechnology (School of Chemical Engineering).

Dr. Asghari's group aims to find and develop the novel vascular endothelial growth factor receptor (VEGFR)-targeting peptides to combat pathological angiogenesis in tumors and major blinding retinal diseases such as aged macular degeneration (AMD), and improve tumor imaging. Moreover, nanomedicinal systems are being used to combine cancer treatment and tumor imaging. His Lab., Biochemical Engineering Lab., has close collaborations with Tehran University of Medical Sciences Preclinical Core Facility, Tehran University of Medical Sciences Faculty of Pharmacy, Shahid Beheshti University of Medical Sciences Ophthalmic Research Center and KNTU Peptide Synthesis Lab.

Research Interests:

Receptor tyrosine kinases (RTKs) are key molecules in numerous cellular processes, the inhibitors of which play an important role in the clinic. Among them are the vascular endothelial growth factor (VEGF) family members and their receptors (VEGFRs), which are essential in the formation of new blood vessels by angiogenesis. Angiogenesis underlies many severe diseases including different cancers and major blinding retinal diseases such as aged macular degeneration (AMD). This observation has driven development of specific inhibitors that block a central factor in tumor growth and AMD, VEGF, from binding to its receptors VEGFR-1 and mainly VEGFR-2. In Biochemical Engineering Lab., we focus on the designing and characterization of small peptidomimetics that target the extracellular ligand-binding domain of both VEGFR1 and VEGFR2. These peptides specifically prevent the binding of VEGF family members to their receptors and downstream signaling. VEGFR-targeting peptides can serve as theranostic agents (i.e. applicable for both therapeutic and diagnostic purposes) in oncology and ophthalmology. An important aspect in our strategy is dual blockade of VEGFR1 and VEGFR2, resulting in greater targeting efficiency and, consequently, more effective inhibition of angiogenesis. We also apply nanomedicinal approaches to enhance the functional properties and the circulation half-life of the peptides, and/or to combine the cancer treatment with tumor imaging. In this regard, we are currently working on nanoalbumin (NAB)-based drug delivery, solid lipid nanoparticles (SLNs) and gold nanoparticles.

Projects:

  1. Improvement of the receptor binding property of the peptides. Given that the binding affinity is a critical aspect in the application of the targeting molecules, we devote considerable efforts to enhance the binding affinity (decreasing the dissociation constant (Kd)) of the peptides toward the ectodomain of VEGFRs.
  2. Application of the VEGFR-targeting peptides for treatment of cancer. To assess the antitumor effects of peptides, different in vitro and in vivo experiments are being used. The in vitro characterizations, using human umbilical vein endothelial (HUVE) and/or different tumoral cell lines, include cell proliferation, migration, angiogenesis, apoptosis induction and the downstream signaling pathways of VEGFRs. The in vivo studies are carried out in animal research facility of IBB. In this core facility, extensive animal studies in the field of translational medicine are carried out. To this end, we deliver the peptides in tumor-bearing animal models alone or in combination with chemotherapeutics via direct injection or using nanosystems, including nanoalbumin (NAB), solid lipid nanoparticles (SLNs) and gold nanoparticles, and evaluate the efficacy of treatments. In collaboration with the Tehran University of Medical Sciences Preclinical Core Facility, we use animal-PET, micro-CT and animal-SPECT to investigate the biodistribution and anti-metastatic potential of our therapeutics.
  3. Application of VEGFR-targeting peptides for treatment of aged macular degeneration (AMD). In this project, in collaboration with Shahid Beheshti University of Medical Sciences Ophthalmic Research Center, we aim to apply our anti-angiogenic peptides for treatment of the neovascular angiogenesis in AMD. Accordingly, besides in vitro studies, the animal models of AMD are treated by the peptides via either intraperitoneal injection or eye drops.
  4. Designing and characterization of the peptide-based contrast agents for imaging of breast and brain tumors. In this project, funded by National Institute for Medical Research Development (NIMAD), we use our VEGFR-binding peptides, e.g. as peptide-DTPA-Gd or peptide-DTPA-Ga68, for contrast enhancement in MRI and PET imaging, respectively, using animal models of breast and brain tumors.

Courses

Enzymology

Enzymology is the branch of biochemistry aiming to understand how enzymes work through the relationship between structure and function and how they fold into their native state. This multidisciplinary research field integrates areas of biochemistry, microbiology, molecular biology, molecular genetics, and biophysics. In addition, given the therapeutic and commercial success of small-molecule enzyme inhibitors, as exemplified by kinase inhibitors in oncology, a major focus of current drug-discovery and development efforts is on enzyme targets.

Syllabus Details

1) Enzyme classification. 2) Oligomeric enzymes (Advantages of enzyme oligomerization). 3) Transition state theory. 4) Explaining the efficiency of enzyme catalysis. 5) Chemical kinetics. 6) Enzyme active site. 7) Kinetics of one-substrate enzymatic reactions. 8) Methods for plotting initial-rate data. 9) Bisubstrate kinetic mechanisms. 10) Factors affecting the activity of enzymes. 11) Enzyme inhibition. 12) Brief fundamentals of enzyme assay. 13) How calculate the enzyme reaction rate, Km, kcat, kcat/Km, and specific activity. 14) Examples of enzyme mechanism.

Student Learning Outcomes

The major learning objective of the course is to understand the thermodynamic basis of catalysis, theories of enzyme kinetics, the mechanisms of enzyme catalysis, enzyme assay and the mechanisms of enzyme regulation in the cell. At the conclusion of the course students should be able to:

· Describe transition-state theory and Arrhenius equation.

· Describe and use the equations of enzyme kinetics.

· Describe the methods used in enzyme kinetics.

· Describe the principles of enzyme inhibition.

· Describe the mechanisms of enzyme catalysis.

· Describe the determination of enzyme's kinetic parameters (Km, kcat, kcat /Km, specific activity).

· Describe the catalytic mechanisms employed by the most well-characterized enzymes.

· Describe the mechanisms of enzyme regulation.
