Title: Protein Quality Control and Cancer Therapy
To safeguard proteomic integrity, eukaryotic cells rely on the ubiquitin proteasome system to degrade aberrant polypeptides and the autophagy pathway to eliminate protein aggregates. Inhibition of these protein quality control (PQC) systems in cells leads to unbalanced protein homeostasis (proteostasis) network, which culminates in cell death.  Many types of cancer cells are particularly sensitive to perturbed proteostasis network given their strong reliance on protein synthesis for growth.  As a result, targeting PQC pathways has been demonstrated to be an effective therapeutics for certain types of cancer.  The presentation will discuss the mechanism of endoplasmic reticulum-associated degradation (ERAD), a PQC mechanism that degrades misfolded ER proteins, and the possibility of targeting key ERAD regulators in cancer therapy.  A novel PQC pathway that might be a potential anti-cancer target will also be discussed.

William Frey

Dr. William H. Frey II is the Founder and Co-Director of the Alzheimer's Research Center at Regions Hospital, Professor of Pharmaceutics and faculty member in Neurology, Oral Biology and Neuroscience at the University of Minnesota and consultant to the pharmaceutical and biotechnology industry. The intranasal insulin treatment he developed for Alzheimer’s disease has been shown in multiple clinical trials to improve memory in both Alzheimer’s patients and normal adults. The intranasal therapeutic (stem) cell treatment he discovered has been shown to bypass the blood-brain barrier to treat Parkinson's, stroke, neonatal ischemia, multiple sclerosis and subarachnoid hemorrhage in animal models of these disorders.

Read a recent Neurology Reviews cover story written by their editor entitled: Intranasal Drug Delivery Bypasses the Blood-Brain Barrier which describes intranasal treatments based on Dr. Frey's discoveries using drugs, peptides, biologics and therapeutic stem cells for Alzheimer's, Parkinson's, MS, brain tumors, stroke, traumatic brain injury and other brain disorders: PDF icon Click Here

Pi-Yong Shi

Title: Flavivirus Antiviral and Vaccine Development
The Shi lab integrates both academic and industrial expertise for basic and translational research. Their research focuses on flaviviruses that cause significant human diseases, such as dengue, Zika, West Nile, and Japanese encephalitis viruses. Despite their global public health burden, there is no clinically approved therapy for flavivirus infection. To address this huge unmet medical need, they take a multidisciplinary approach (i) to study the molecular mechanism of viral replication and (ii) to translate the knowledge into antiviral, vaccine, and diagnostic products.

Daniel Harki

Title: Modulation of Transcription Factor Signaling with Covalent Small Molecule Inhibitors

Transcription factors (TFs) are DNA-binding proteins that modulate the transfer of genomic information to mRNA (and ultimately proteins) in cells. Aberrant TF activity causes many human diseases, such as chromic inflammation (elevated NF-kB signaling) and prostate cancer (elevated androgen receptor signaling), among others. Over 1000 TFs are believed to be encoded in the human genome, but only a fraction of TFs have been annotated for structure and function. Despite their central roles in human disease, TF-modulating drugs are largely unrealized due to challenges associated with developing TF-binding molecules. Our group has developed chemical modulators of NF-kB (p50/p65) signaling that (i) covalently engage upstream kinases that activate the p50/p65 heterodimer for transcription, (ii) directly target p65 and block the ability of the p50/p65 heterodimer to bind DNA, and (iii) mimic the endogenous DNA binding site of the p50/p65 heterodimer and sequester it. The development of these unique NF-kB modulators, our efforts to develop next-generation compounds, and thoughts on their potential applications will be presented.

Ravit Boger MD

Title: Drug Development for Cytomegalovirus

Dr. Ravit Boger is an associate professor of pediatrics and oncology at the Johns Hopkins University School of Medicine. Her area of clinical expertise is pediatric infectious diseases. She is known for her research on congenital cytomegalovirus (CMV) infection. Her lab was among the first in this country to characterize CMV genes, and they recently identified a protein that regulates the body’s immune response to CMV.

The main themes of Boger group's research include:

  • CMV INHIBITION BY ARTEMISININ-DERIVED DIMERS: Boger group has shown that artemisinin-derived dimers inhibit human CMV replication significantly more that artemsinin-derived monomers, a pattern that has been observed in inhibition of cancer cell lines. Current work focuses in identifying mechanisms of CMV inhibition by these compounds and their effects on cell-signaling pathways.
  • MODELS OF ANTI-VIRAL COMBINATION THERAPY: Boger group has performed extensive analysis of CMV inhibition using combination of known CMV inhibitors. Using several models for analysis of drug combination they have shown that the slope parameter is an important factor in distinguishing between classes of CMV inhibitors and for analyzing the outcome of drug combination.
  • ROLE OF WNT PATHWAY IN CMV REPLICATION: Prof. Boger and coworkers have shown that in contrast to other herpesviruses (such as EBV and KSHV) CMV infection of human foreskin fibroblasts results in inhibition of the WNT pathway.
  • CMV CONTROL BY NOD1 AND NOD2: Boger group has shown that NOD1 and NOD2 recognize CMV and restrict virus replication. They are studying mechanisms of CMV control by NOD1 and NOD2, and the effects of their polymorphisms on virus replication.

David Yu

Title:Elucidating and Exploiting SIRT2 and SAMHD1 in the DNA Damage Response
The SIRT2 sirtuin deacetylase and tumor suppressor proteins directs the replication stress response and more generally DNA damage response and is a novel target for cancer therapy. SAMHD1 is a dNTP triphosphohyrodylase that is well-established in restricting HIV-1 infection but also has a novel dNTPase indepedent function in directing DNA double-strand break repair by homologous recombination through DNA end resection, which may be exploited for cancer therapy
