Xingui Liu
University of Dundee
Discovery of XL01126: a PROTAC degrader of Leucine Rich Repeat Kinase 2
Xingui is currently a Marie Skłodowska-Curie fellow in Prof. Alessio Ciulli’s lab at the Center for Targeted Protein Degradation (CeTPD), where she is focusing her research on developing PROTAC degraders of Leucine Rich Repeat Kinase 2 (LRRK2), a promising target for Parkinson’s disease. Before joining the Ciulli group, she was a Postdoc associate at the University of Florida working with Prof. Guangrong Zheng and Prof. Daohong Zhou. At the University of Florida, she was part of a team that developed very effective BCL-XL/BCL-2 PROTAC degrader molecules. One of which was licensed to the Dialectic Therapeutics and led to the development of one of the first VHL-based PROTACs to enter the clinic and to be dosed in human patients for the treatment of hematological malignancies. She completed her PhD in Guangrong Zheng’s lab at University of Arkansans for Medical Sciences, where she designed, synthesized, and characterized delta-tocotrienol based radio-protectors.

High through-put interrogation of the UPS
Stephen J. Elledge is the Gregor Mendel Professor of Genetics and Medicine at Harvard Medical School and the Brigham and Women’s Hospital Division of Genetics, and is a Howard Hughes Medical Institute Investigator. He received his B.S. in chemistry from the University of Illinois and his Ph.D. in biology from the Massachusetts Institute of Technology. He began his laboratory at the Baylor College of Medicine in Houston and moved in 2003 to the Brigham and Women’s Hospital and Harvard Medical School Department of Genetics. He is an elected member member of the National Academy of Sciences, National Academy of Medicine, and American Academy of Arts and Sciences. His many awards include the Dickson Prize (2010), Lewis S. Rosenstiel Award for Distinguished Work in the Basic Medical Sciences (2013), Gairdner Foundation International Award (2013), Albert Lasker Basic Medical Research Award (2015), Breakthrough Prize in Life Sciences (2017) and the Gruber Prize in Genetics (2017).
Dr. Elledge’s research interests center on genetic approaches to biological problems including the study of proteins that sense and respond to DNA damage, and regulate the cell division cycle and cancer. Through this work he uncovered a protein kinase cascade that is now known as the DNA Damage Response. He discovered F-box proteins and Skp1 and along with Dr. Wade Harper, uncovered the two largest families of E3 ubiquitin ligases: the cullin-RING ligases (CRL), starting with the Skp1-Cul1-F-box sub-family, and the RING domain ligases. He has also worked in unraveling the role of cancer drivers in the evolution of cancer through aneuploidy and how tumor suppressors allow cancers to evade the immune system. More recently Dr. Elledge has developed a suite of immunological methods, such as T-Scan, VirScan and EpiScan, that allows the genome-wide identification of epitopes recognized by B and T cells. He has used these tools to investigate the role of viruses in human disease such as Measles, MS and COVID-19.

Vincenzo D'Angiolella
Oxford Institute for Radiation Oncology
Neomorphic mutations in E3 ubiquitin ligases to divert substrate specificity
Vincenzo D’Angiolella is an Associate Professor at the Oxford Institute for Radiation Oncology. His research group focuses on understanding the role of the ubiquitin system in cancer pathogenesis and response to treatment with chemo- and radiotherapy. He is currently holding two programme grants from the Cancer Research UK (CRUK) and Medical Research Council (MRC), focused on the role of Cullin Ring ubiquitin Ligases (CRLs) in brain cancers (medulloblastoma and glioblastoma) pathogenesis. Studies from his laboratory have uncovered the mechanism of action and function of Fbxl17 in medulloblastoma (Raducu et al., 2016) and highlighted a novel synthetic lethal interaction between cyclin F loss and Chk1 kinase inhibition (Burdova et al., 2019). More recently, the laboratory has identified that mutations occurring on the E3 ligase KBTBD4 in medulloblastoma change substrate specificity driving the recognition of the chromatin remodelling complex CoREST (Chen et al., 2022). This work describes the first neomorphic mutation in an E3 ubiquitin ligase and elucidates a novel mechanism of tumorigenesis in medulloblastoma. Vincenzo has a Medical Degree (MD) from the University of Naples “Federico II” and completed his PhD at the same University in the field of General Pathology. During his PhD utilizing X. Laevis as a model system, he investigated the process of mitosis and spindle checkpoint (D'Angiolella et al., 2001; D'Angiolella et al., 2003; D'Angiolella et al., 2007) Following the completion of his studies, he worked as a postdoctoral fellow at the New York University School of Medicine in the USA in the laboratory of Professor Michele Pagano. During the postdoctoral studies, he elucidated the mechanism-of-action and function of cyclin F, the founding member of the F-box proteins. He uncovered that cyclin F does not partner with Cyclin Dependent Kinases (CDKs) like other cyclins do, but acts as an E3 ubiquitin ligase, forming a canonical CRL1 (D'Angiolella et al., 2012; D'Angiolella et al., 2010).

The second topic is to study the mechanism of cancers and develop small molecules including covalent and non-covalent inhibitors and proteolysis targeting chimeras (PROTACs) degraders to treat cancers. He has published 42 peer-reviewed papers. His work includes the development of the first-generation selective BCL-XL PROTAC degrader (DT2216) and the second-generation BCL-xL and BCL-2 dual-degrading PROTAC (753b). DT2216 is currently being investigated as a novel anticancer agent in a Phase-1 clinical trial at Dialectic Therapeutics. Most recently, he led an interdisciplinary team to build new assays for target identification and validation, and to discover new E3 ligase ligands to extend the frontiers of targeted protein degradation.

Muhammad Murtaza Hassan
Stanford University
Murtaza, born in Pakistan, and raised in Canada where he conducted his university studies (HBSc, University of Toronto 2009-2013; MSc, York University 2014-2017, Supervisor: Edward Lee-Ruff; PhD, University of Toronto 2017-2021, Supervisor: Patrick T. Gunning) is an avid chemical biology enthusiast.
For his doctoral studies at the Gunning lab, Murtaza developed some of the most potent and selective HDAC8 inhibitors in literature, using conformationally constrained benzamides to complement the unique HDAC8 pocket.
Currently, his postdoctoral work with Professor Nathanael Gray at Stanford focuses on expanding current pharmacological tools to target the undruggable proteome. One example of this involves exploring the potential for trans-labelling molecules. Based on the JQ1 scaffold, Murtaza developed MMH1 and MMH2, that bind BRD4 non-covalently, but covalently trans-label DCAF16 (an E3 ligase), leading to the targeted degradation of BRD4. These monovalent trans-labelling molecules demonstrate nanomolar BRD4 degradation, on-par with well-established bivalent degraders such as MZ1 and dBET6.
