A paper entitled "Autoactivation of thrombin precursors" by Nicola Pozzi, Ph.D. and the Di Cera lab will be published in the April 16 edition of The Journal of Biological Chemistry. The cover of the journal will feature a figure created by Tracey Baird, showing the crystal structures of the mutant S195A prethrombin-2 (cyan) and thrombin (gold) bound to argatroban (yellow sticks).
The paper discusses new findings showing that thrombin zymogen precursors are capable of catalytic activity and autoactivation. Activity of the mature thrombin protease is regulated by conformational selection in the trypsin fold, which could unlock autoactivation of the zymogen. Both the zymogen and protease exist in equilibrium between the active and inactive forms, which helps regulate the catalytic activity of the protease and could unlock activity of the zymogen. The production of enzymes through zymogen autoactivation could be applied to many clinically relevant trypsin-like proteases.
The results of the seventh round of the President's Research Fund were announced recently. Two Biochemistry faculty were among the recipients of these awards.

Joel Eissenberg, Ph.D., Professor of Biochemistry, recently published an article in the January/February 2013 issue of Missouri Medicine. The article, entitled "Telomeres, Cancer & Aging: Live Long and Prosper?" reviews research on telomeres, protective DNA sequences at the ends of chromosomes. Telomeres could play a role in aging and lifespan, since they protect chromosome ends from fraying and damage. They could also be a potential target for treating tumor cells, which have a much higher expression of telomerase, helping them to achieve immortality through telomere stability.
Alessandro Vindigni, Ph.D., Associate Professor of Biochemistry, recently published new findings that could help to improve existing chemotherapy treatments for cancer patients. The study, published in Nature Structural and Molecular Biology on February 10, details their work on the role of RECQ1 helicase during replication stress response, particularly in tumor cells after anticancer drug treatment with DNA topoisomerase 1 inhibitors. This work challenges long-established models of how DNA replication deals with genotoxic stress and provides a new rationale for the design of novel targeted inhibitors to sensitize cancer cells to much lower doses of the selected chemotherapeutic agent that are not toxic to normal cells.
Ray Kreienkamp, a second year medical student at SLU, won second prize in the 48th annual Alpha Omega Alpha Medical Honor Society student research forum held in January. The research for his presentation, entitled "Negative role of cathepsin-L in regulation of homologous recombination," was conducted in the laboratory of Susana Gonzalo, Ph.D., Assistant Professor of the Department of Biochemistry.
Ray competed against 40 total students during the initial poster presentation on January 10 and was one of six finalists selected to give an oral presentation on his work on January 30.
Susana Gonzalo, Ph.D., Assistant Professor of Biochemistry, and her lab group have identified possible new diagnostic markers and treatments for breast cancers classified as "triple-negative." These cancers, which are difficult to treat and have a poor prognosis, tend to affect younger women who often have the BRCA1 mutation and are at an increased risk for breast and ovarian cancers.
Susana's group found a pathway that is activated in triple-negative breast cancers and responsible for unchecked tumor cell growth, making these tumors especially difficult to treat. This pathway is turned off by vitamin D, which could provide a new way to treat these cancers by helping traditional therapies to be more effective. They also identified three biomarkers that could help identify those patients who would most benefit from vitamin D treatment.
Susana's research was recently published in The Journal of Cell Biology. Her lab group worked in collaboration with the labs of Xavier Matias-Guiu and Adriana Duso at IRBLleida in Spain. The work was partially funded by a $500,000 Department of Defense grant. You can read the full story here.
Sergey Korolev, Ph.D., Associate Professor of Biochemistry, received a grant from the Center for the Advancement of Science in Space (CASIS) to advance crystallization of medically relevant proteins using microgravity. As part of this project, CASIS will assist Dr. Korolev in coordinating access to the International Space Station National Laboratory (ISS NL) for the purposes of using the microgravity environment and a counter-diffusion method to improve the crystal quality of two key proteins: human calcium-independent phospholipase PLA2g6 and prothrombin. Both proteins are essential players in the cardiovascular system and inflammatory cascades.
The microgravity environment will facilitate the solution of an atomic resolution structure and will help obtain better crystals, revealing the conformation of the proteins and allowing for analysis of the functional sites. These structural studies will permit development of new therapeutic approaches to treat multiple devastating diseases. Thrombin is one of the most important pharmacological targets in blood coagulation, while the PLA2g6 protein is a novel promising target for cardiovascular disease as well as for muscular dystrophy, Parkinson's disease, and diabetes.
The overall mission of CASIS is the advancement of educational and scientific research in connection with the ISS NL. Among CASIS's goals are efforts to fully utilize the ISS NL and enable technology that enhances utilization of the ISS NL by commercial interests, other government agencies, and educational entities.
Dale Dorsett, Ph.D., Professor of Biochemistry and Ángel Baldán, Ph.D, Assistant Professor of Biochemistry, have been named Outstanding Scientists in 2013 by the Academy of Science of St. Louis. Dr. Dorsett will receive the Fellows Award and Dr. Baldán will receive the Innovation Award.
Dale has been called "the godfather of cohesinopathies." His discoveries have steered the course of understanding and potential therapy for this class of human genetic disorders. Dale's pioneering work has advanced knowledge in the fundamental mechanism of gene control during development. His research papers have been cited in thousands of publications, testifying to the impact of his discoveries on modern cell and molecular biology. The impact of his work truly extends from the bench to the clinic.
Ángel began his groundbreaking studies on atherosclerosis as a postdoctoral fellow at UCLA. He showed that mice lacking a protein called ABCG1 develop massive cholesterol deposition and lipid release in the lung, resembling life-threatening human respiratory distress syndrome. This has important implications for the clinical course of lung infections, asthma, allergies and chronic obstructive pulmonary disease. Since moving to St. Louis, Ángel discovered the gene for sterol regulatory element binding protein 2 (SREBP-2) contains within it a second gene for a key regulatory RNA, called miR-33. This finding uncovered an unexpected mechanism by which the cholesterol-lowering statin drugs work and showed that miR-33 regulates key bile transporters in the liver, significant for patients with certain mutations. These findings suggest novel therapeutic approaches to manage patients at risk for cardiovascular disease and provide new insight into statin therapy and improving the effectiveness and safety of cholesterol-lowering medication.
The Outstanding St. Louis Scientist Awards will be presented on April 24, 2013 in the Starlight Room of the Chase Park Plaza. For more information on the awardees, please see the story in Newslink.

Ray's research focuses on two areas of the blood clot cascade. His lab's newest line of research investigates the role of antithrombin in blood vessel wall inflammation. This important work could lead to improved treatments for patients of strokes, heart attacks and embolisms. His previous work, for which he was awarded an NIH grant in 2010, aims to prevent organ failure in sepsis patients by increasing the clotting activity of activated Protein C.
Ray's research was recently awarded a four-year grant from the National Heart, Lung and Blood Institute for the antithrombin studies.
Enrico Di Cera, M.D., Alice A. Doisy Professor and Chairman of Biochemistry, has been awarded a five-year subcontract as part of a U54 Translational Research Centers in Thrombotic and Hemostatic Disorders (TRC-THD) Specialized Center grant headed by Evan Sadler, Ph.D., at Washington University. The application, which consists of 5 projects and 4 Core Units, was awarded by the National Heart, Lung and Blood Institute at the National Institutes of Health.
The overall goal of the grant is to improve the health and survival of thrombosis patients by initiating collaborations between basic scientists and clinicians to develop new treatments for thrombosis. Dr. Di Cera's project entitled "Engineering thrombin for exclusive activity toward Protein C" has two parts: 1) elucidation of the molecular mechanism of action of existing anticoagulant thrombin mutants; and, 2) conversion of thrombin into an exclusive activator or protein C.
Enrico Di Cera, M.D., Alice A. Doisy Professor and Chairman of Biochemistry, has been awarded a four-year grant entitled "Studies on the anticoagulant properties of thrombin" from the National Heart, Lung and Blood Institute at the National Institutes of Health.

We are pleased to announce that Yoonsang Cho, Ph.D., is joining the Department as Assistant Professor, effective July 2012. Dr. Cho was formerly an Associate Research Scientist in the Department of Pharmacology at Yale University School of Medicine.
Yoonsang is an established investigator studying the structural and chemical biology of ligands and receptors in inflammation and cancer. Immune cells interact indirectly with other cells via small protein ligands, such as cytokines and growth factors, but the mechanisms behind these interactions is not well understood. His research aims to unlock the molecular details of the ligand-receptor interactions in the hope that these molecules might be used as models to develop new therapies for cancer and inflammatory diseases.
Ángel Baldán, Ph.D., Assistant Professor of Biochemistry, was featured in Newslink in July for his continuing research on the microRNA, miR-33. Their most recent research focuses on the way that miR-33, which is induced by statins, can decrease bile production in the gallbladder, affecting the digestion of dietary lipids, which causes cholestasis and can lead to liver damage. Treatment with anti-miR-33 reversed the toxic side effects of statins in an animal model.
These important findings could lead to better statins to help control cholesterol levels, by reducing the liver damage that can be a side effect of these drugs. Their research could also help treat some genetic disorders that cause a similar defect in bile transporters and ultimately lead to liver damage through cholestasis.
Dr. Baldán's research was recently published in EMBO Molecular Medicine.
