AbstractA defining challenge in synthetic biology is the development of high-throughput and automated methodologies for precise design and engineering of cells. To address these challenges, we develop multiplex genome engineering technologies for versatile genome modification and evolution of bacterial and eukaryotic cells. We use these technologies to create genetic variants to reveal a causal understanding of complex phenotypes as well as engineer pathways and recode genomes. These Genomically Recoded Organisms (GROs) contain alternative genetic codes, in which codons have been eliminated from the genome of E. coli. GROs exhibit improved properties for incorporation of nonstandard amino acids that expand the chemical diversity of proteins or polymers, establish genetic isolation and multi-virus resistance, and enable the engineering of GROs to depend on synthetic amino acids for robust biocontainment strategies. We have also developed new computational-experimental technologies – computer aided design of synthetic genetic elements (CAD-SGE) – that permits the redesign, expression, and mobilization of biosynthetic pathways in diverse organisms for the discovery of new metabolites. This work increases the toolbox for genomic and cellular engineering with broad applications for new classes of enzymes, materials, and therapeutics.

AbstractViruses and virus-like mobile genetic elements are ubiquitous parasites (and sometime symbionts) of all cellular life forms and the most abundant biological entities on earth. The recent, unprecedented advances of comparative genomics and metagenomics have led to the discovery of diverse novel groups of viruses and a rapid expansion of the chartered region of the virosphere. These discoveries provide for a vastly improved understanding of the evolutionary relationships within the virosphere. Arguably, we are approaching the point when the global architecture of the virus world can be outlined in its entirety, and the key evolutionary events in each of its domains can be reconstructed. I will present such an outline of the global organization of the virosphere and the corresponding megataxonomy, including 6 distinct virus realms, that has been recently approved by the International Committee on Taxonomy of Viruses, as well as some new candidates. The expansion of the prokaryotic virosphere that is being shown to include many groups of viruses, particularly, those with RNA genomes, previously thought to be eukaryote-specific, will be emphasized. I will further discuss the position of viruses within the wider space of replicators and the recent dramatic expansion of the “alternative virosphere” that includes viroids and diverse viroid-like viruses that seem to have evolved on multiple, independent occasions.

AbstractAbstract: While research institutions including Weizmann are leading the way in cutting edge work in omics data analysis and modeling, biotechs and pharma are very advanced, and in some cases leading, in areas related to molecular design and clinical data analysis. I have been leading the AI / ML work for R&D at one of the largest pharma companies for almost two years and will share some of the methods we have been developing and using to address computational challenges across all stages of the drug discovery and development process. I Will also try to share some of the lessons I have learned over this period.

AbstractEarly detection of recurrence and monitoring of Molecular Residual Disease (MRD) post-surgery is critical for clinical decision-making to tailor personalized treatments across solid cancers. C2i Genomics has developed an ultra-sensitive whole-genome ctDNA test, allowing extremely accurate and sensitive monitoring of patients with solid tumors. Here we present results from applying whole-genome sequencing (WGS) and identification of ctDNA across a variety of adult and pediatric solid tumors. We integrate a genome-wide mutation and copy number monitoring approach coupled with advanced signal processing and Artificial Intelligence (AI) for measuring the tumor load from low-input blood samples (~1mL of plasma) with ultra-sensitive detection. The increased sensitivity allowed clinical detection of tumor fraction down to 5*10-5 and recurrence detection sensitivity achieving >65% at the first two months after definitive treatment, enabling earlier clinical intervention for high-risk patients.

AbstractDespite favorable initial response to therapy, a third of cancer patients will develop recurrent disease and succumb to it within five years of diagnosis. While there has been much progress in characterizing the pathways that contribute to stable genetic drug resistance, the mechanisms underlying early reversible resistance, also known as persisters-driven resistance, remain largely unknown. It has long been believed that persisters represent a subset of cells that happen to be non-proliferating at the time of treatment, and therefore can survive drugs that preferentially kill rapidly proliferating cells. However, in my talk I will describe a rare persister population which, despite not harboring any resistance-conferring mutation, can maintain proliferative capacity in the presence of drug. To study this rare, transiently-resistant, cycling persister population, we developed Watermelon, a high-complexity expressed barcode lentiviral library for simultaneous tracing of each cell’s clonal origin and proliferative and transcriptional states. We combine single cell transcriptomics with imaging and metabolomics to show that cycling and non-cycling persisters arise from different cell lineages with distinct transcriptional and metabolic programs. Finally, I will describe how by studying persister cells we can gain critical insights on cellular memory, fate, and evolution, which can guide the development of better anti-cancer treatments.

AbstractSleep is ubiquitous in the animal kingdom, but its function has been a mystery. Besides its importance for the brain, sleep appears to play an essential physiological role, emphasized by the fact that severe sleep loss can be lethal. The cause of this lethality was unknown. We found that extreme sleep deprivation results in high levels of reactive oxygen species (ROS) that trigger oxidative stress specifically in the gut of flies and mice. Using flies, we show that neutralization of intestinal ROS prevents premature death of sleep-deprived animals, suggesting a causal link between ROS accumulation in the gut and lethality upon sleep loss. What may explain the observed phenomena? Could it teach us about the normal, daily function of sleep? In the second part of my talk, I will present our current attempts and preliminary data aiming at answering these questions.

AbstractA fresh biography of Galileo Galilei which puts his scientific discoveries in context. Disturbed by rampant science denial in America—and around the world—that has only intensified in recent years, I began researching the life, ideas, and actions of this brilliant man who encountered similar pressures centuries ago. The result is a biography filled with lessons relevant for today—whether with respect to trusting the advice given by scientists in relation to COVID-19, the reality of climate change, the efficacy of vaccines, or the teaching of creationist theories in schools. I will discuss these topics in this talk.

AbstractI will present trans-Tango, a new technique for anterograde transsynaptic circuit tracing and manipulation that we have established in fruit flies. At the core of trans-Tango is a synthetic signaling pathway that is introduced into all neurons in the animal. This pathway converts receptor activation at the cell-surface into reporter expression through site-specific proteolysis. Specific labeling is achieved by presenting a tethered ligand at the synapses of genetically defined neurons, thereby activating the pathway in their postsynaptic partners. Activation of the pathway culminates in expression of a reporter that can be visualized. Because our system is modular, it can be easily adapted to experiments in which the properties of specific circuits are modified and the functional consequences are analyzed. We first validated trans-Tango in the Drosophila olfactory system and then implemented it in the gustatory system, where projections beyond the firstorder receptor neurons are not well characterized. We identified second-order neurons within the sweet and bitter circuits and revealed that they target brain areas involved in neuromodulation with similar but distinct projection patterns. I will also present experiments in which we use trans-Tango in functional analysis of the gustatory circuits. Using our studies in flies as proof of concept, we are currently establishing an equivalent technique for labeling circuits in vertebrate models, such as mice and zebrafish. These experiments establish trans-Tango as a flexible platform for comprehensive transsynaptic analysis of neural circuits.

AbstractProtein homeostasis is critical for cellular function and survival. Dysregulation of the cellular protein homeostasis can lead to a build-up of misfolded proteins and facilitate the manifestation of a variety of pathological disorders including neurodegeneration, cancer and inflammation. Where and how the misfolded proteins accumulate, however, has remained a mystery. In studying MUC1 kidney disease (a rare kidney disorder), we have found that some of these pathologies may share a single, previously unrecognized cellular mechanism: a jam at a specific step in the secretory pathway involving a cargo receptor called TMED9. A small molecule called BRD4780 can break the jam and restore cells to normal function, providing a promising potential for therapeutic developments.

AbstractIt is a challenge to answer questions like: why some people develop a disease, react to a specific treatment and/or develop severe side-effects while others don’t. In order to explain these occurrences, one has to take a holistic approach and study the body physiology from a systems level perspective. Longitudinal multi-omics measurements together with genetics, on a large population, can serve such a purpose and help in predicting, reasoning, and preventing diseases. In partnership with Arivale Inc., we have developed infrastructure to collect longitudinal Personalized Dense Dynamic Data clouds (PD3 clouds) on thousands of individuals, which include genetics and longitudinal measurements of clinical labs, microbiome, metabolome, proteome, and self-reported data. The value of these extremely high-dimensional data clouds is clear; however, it also comprises a challenge in data analysis and interpretation. One way to reduce data dimensionality is called Pareto Task Inference (PARTI, Hart et al. 2015). We used this method to analyze the clinical labs and found that the data falls on a significant tetrahedron. The 4 vertices are archetypes that specialize in a certain task. Using all other datatypes, we identified enriched traits next to every archetype and revealed the underline tradeoffs that shape the data. This distinctive analysis uncovers unexpected relationships between datasets such as metabolomics, proteomics and clinical labs, and helps in interconnecting the different datatypes to characterize different states of human health.
