ABOUT
Thomas Kislinger received his MSc in Analytical Chemistry from the University of Munich, Germany (1998). He completed his PhD in 2001, investigating the role of Advanced Glycation Endproducts in diabetic vascular complications at the University of Erlangen, Germany and Columbia University, New York. Between 2002 and 2006 he completed a post-doctoral fellowship at the University of Toronto. In 2006 he joined the Princess Margaret Cancer Centre as an independent investigator. Dr. Kislinger holds positions as Senior Scientist at the Princess Margaret Cancer Centre and as Professor and Chair at the University of Toronto in the Department of Medical Biophysics. The Kislinger lab applies proteomics technologies to translational and basic cancer biology. This includes the development of novel proteomics methodologies, identification of liquid biopsy signatures and the molecular identification of novel cell surface markers.

ABSTRACT
Background: The early environment provides many cues to young organisms that guide their development as they mature. Maternal personality and behavior are an important aspect of the environment of the developing human infant. The molecular mechanisms by which these influences are exerted are not well understood. We attempted to identify whether maternal traits could be associated with alterations in DNA methylation patterns in infants.
Methods: 32 women oversampled for history of depression were recruited in pregnancy and provided information on depressive symptoms, attachment style, and history of early life adversity. Buccal cell DNA was obtained from their infants at six months of age for a large-scale analysis of methylation patterns across 5×106 individual CpG dinucleotides, using clustering-based criteria for significance to control for multiple comparisons. Separately, associations between maternal depression, attachment style, and history of adversity and psychobehavioral outcomes in preschool-age children were examined.
Results: Tens of thousands of individual infant CpGs were alternatively methylated in association with each of the three studied maternal traits. Genes implicated in cell-cell communication, developmental patterning, growth, immune function/inflammatory response, and neurotransmission were identified. The result sets were highly coextensive among the three maternal traits, but areas of divergence exhibited intriguing parallels with behavioral outcomes.
Conclusions: Maternal personality traits are an important aspect of the infant environment that shapes offspring development in many ways. Infant genes that are epigenetically modified in reponse to maternal traits are potential candidate mediators for these effects. We have identified a large number of such genes and demonstrated parallels to clinically measurable outcomes in children.
ABOUT
Dr. Robakis is a psychiatrist with clinical and research interests in perinatal mood disorders and in the contribution of early life experiences to adult mental health and illness. She completed her M.D. as well as a Ph.D. in developmental neurobiology at Columbia University’s Medical Scientist Training Program, residency training in psychiatry at Stanford University School of Medicine, and a research fellowship in perinatal mood disorders also at Stanford. She remained on the clinical faculty at Stanford until 2019, when she accepted a position at the Icahn School of Medicine at Mount Sinai, where she is currently Associate Clinical Professor of Psychiatry and Assistant Director of the Women’s Mental Health Program.
Dr. Robakis’ research interests include the effects of early life stress and disordered attachment on risk for psychiatric illness in the perinatal period, on alterations in metabolism and cognition, and on psychobehavioral development in offspring. She is particularly interested in using epigenetic marks to help identify the biological pathways through which early life experiences exert their effects on outcomes in adulthood and intergenerationally.

ABSTRACT
Metastatic progression defines the final stages of tumor evolution and underlies the majority of cancer-related deaths. The heterogeneity in disseminated tumor cell populations capable of seeding and growing in distant organ sites contributes to the development of treatment resistant disease. We recently reported the identification of a novel tumor-derived cell population, circulating hybrid cells (CHCs), harboring attributes from both macrophages and neoplastic cells, including functional characteristics important to metastatic spread. These disseminated hybrids outnumber conventionally defined circulating tumor cells (CTCs) in cancer patients. It is unknown if CHCs represent a generalized cancer mechanism for cell dissemination, or if this population is relevant to the metastatic cascade. We detect CHCs in the peripheral blood of patients with cancer in myriad disease sites encompassing epithelial and non-epithelial malignancies. Further, we demonstrate that in vivo-derived hybrid cells harbor tumor-initiating capacity in murine cancer models and that CHCs from human breast cancer patients express stem cell antigens, features consistent with the ability to seed and grow at metastatic sites. We reveal heterogeneity of CHC phenotypes reflect key tumor features, including oncogenic mutations and functional protein expression. Importantly, this novel population of disseminated neoplastic cells opens a new area in cancer biology and renewed opportunity for battling metastatic disease.
ABOUT
The research focus of the Wong laboratory revolves around understanding the regulatory mechanisms that control epithelial stem cell homeostasis and their expansion in developmental, homeostasis and disease contexts, including cancer. I have substantial training and experience in intestinal stem cell investigation leveraging in vivo and ex vivo modeling, as well as in myriad cutting edge technologies (i.e. cyCIF, scRNA-seq). My publication record spans my post-doctoral fellowship in Dr. Jeffrey Gordon’s laboratory at Washington University School of Medicine, to studies in my own laboratory at Oregon Health & Science University. Our research impacts the understanding of regulatory mechanisms that govern cell state in the context of the evolving tissue microenvironment and changing cell signaling landscape, in development and disease.
Our studies in stem cell regulation led to the intriguing finding that stem cells can fuse with tissue macrophages in the context of injury repair and may impact tissue regeneration. We have extended these findings to the cancer setting, where cancer-macrophage fusions are detectible in primary and metastatic tumors, and my group recently identified and characterized these cells as a novel circulating tumor cell population. Importantly, our studies in cell culture, in mice and humans provide an indepth evaluation of hybrid cells to set the foundation for continued investigations into their biology, impact on disease progression or tissue regeneration, and use as a biomarker for disease burden. Importantly, we coined the term, circulating hybrid cell (CHC) for this novel population and reported they exist at higher levels than conventionally defined circulating tumor cells in the peripheral blood of cancer patients. This work was published in 2018 and highlighted by Science Magazine as one of the top ten publications in the cancer field in the science family journals. The science proposed in this U01 application leverage hybrid cell biology to assess treatment response and resistance in breast cancer patients undergoing targeted therapy. Our proposal leverages active collaborations with Dr. Young Hwan Young’s group to synergize biology with computation, as well as a number of other valuable collaborators to ensure success of the proposed, cutting-edge science.
