Events for May 20 - April 29

TITLE: "Cellular plasticity and fate choices in developing tissues and single cancer cells" ABSTRACT: While cellular processes are often reproducible and precise, cells may also alter their molecular states and adopt new fates in response to stimuli, a phenomena referred to as “plasticity”. I am interested in understanding the control principles governing cellular plasticity and fate […]

TITLE: "Exploration of human genetic and phenotypic diversity through cell villages" ABSTRACT: Our species is characterized by an immense diversity in neurological and psychological traits. Common and rare genetic variants have been linked to trait differences and disease risk in human populations, though the underlying biology is poorly understood and difficult to study at large scales. […]

TITLE: "Imaging-based genetic recording of developmental histories" ABSTRACT: Systems-level understanding of cell fate decisions has been hampered by limitations of the existing methods to capture developmental history of the cells. Synthetic recording, which uses genome editing to create sequence diversity in genetic barcodes, is emerging as a promising approach for mapping cell lineage and molecular history. […]

TITLE: "Genomewide supervised prediction of activating and repressive regions in over hundred cell and tissue types" ABSTRACT: While the vast majority of variants associated with common disease risk are distributed across the non-coding genome, our understanding of the regulatory elements contained within remains notably incomplete. Strategies for identifying and characterizing these regulatory elements, such as […]

TITLE: "XIST controls X chromosome dampening and autosomal genes in early human development" ABSTRACT: Female human pre-implantation embryos and naïve human pluripotent stem cells (hPSCs) equalize X-linked gene expression with males via X-chromosome dampening (XCD), a unique strategy of dosage compensation in mammals. The mechanisms controlling XCD are unknown. Here, we show that the long non-coding […]

TITLE: "Fast estimation of genetic correlation for Biobank-scale data" ABSTRACT: Genetic correlation is an important parameter in understanding the shared genetic basis across pairs of complex traits with applications ranging across disease subtyping, genetic prediction, and causal inference. The availability of genome-wide genetic data has led to a number of methods that aim to estimate genetic […]

TITLE: "Determining mRNA nuclear export kinetics reveals a wide range of values associated with innate immune response genes" ABSTRACT: The abundance and stimulus-responsiveness of mature mRNA is known to be determined by nuclear synthesis and cytoplasmic decay. However, nuclear processing and export events and may also contribute.  Here, we investigated the role nuclear export rates […]

TITLE: "Oncogenic alterations in the p53 pathway abolish oscillatory competence" ABSTRACT: The tumor suppressor p53 displays concentration oscillations in response to DNA damage, a behavior that has been suggested to be essential to its anti-cancer function.  Many genetic alterations in the p53 pathway have been shown to be oncogenic, whether by experiment or by clinical associations […]

TITLE: Structural interrogation of small open reading frame (sORF) encoded proteins ABSTRACT: Advances in genomics and proteomics have unearthed sequences of a startling number of novel proteins. Despite this, our knowledge of their three-dimensional structure and function relies on only a small fraction of the known protein universe.  Small open reading frames (sORFs) encoding proteins less […]
