Rotation Project Description
Lab GEMS Research Concentration Rotation Project Name Project Description Benevolenskaya Molecular Biology and Genetics
Cancer BiologyStudying new mechanisms of drug resistance using single cell RNA sequencing Roles of histone demethylase KDM5A in pRB-mediated differentiation Frolov Molecular Biology and Genetics
Cancer BiologyThe role of Hippo and RB tumor suppressor pathways in control of cell proliferation and differentiation 1) To begin exploring the mechanisms of E2F/Rb-dependent activation of metabolic genes during adult skeletal muscle development.
The expression of metabolic genes is activated by E2F/Rb in differentiating muscle but not in proliferating adult muscle precursors. The goal of the project is to understand the mechanistic basis of these differences. Approaches used: genetics, genomics and biochemistry.
2) Role of Homothorax (Hth) in Hippo pathway in the eye progenitor cells.
The Hippo tumor suppressor pathway controls organ size by regulating the transcriptional co-activator Yki (YAP). Sd is the best known DNA-binding factor that recruits Yki to target genes. Recent data generated in the lab suggest that, in eye progenitor cells Yki is recruited by a different DNA-binding factor called Homothorax (Hth). The goal of this project is to evaluate this hypothesis using single cell genomics, bioinformatics, genetics and cell biology approaches.Kuchay Molecular Biology and Genetics

Cell Biology and Regenerative MedicineUnderstanding the role of aberrant protein turnover at cellular membranes in health and disease. We employ interdisciplinary approaches (e.g., Proteomics, CRISPR/CAS9 gene editing, cell and mouse genetics, biochemistry, pharmacology) to investigate the role of membrane bound E3-ubiquitin ligases, enzymes that mark protein targets with ubiquitin polymers, to induce their complete degradation via ubiquitin proteasome system. We are interested in molecular mechanisms, developing new tools and assays for the membrane compartment specific E3-ligases to leverage our expertise for the targeted- protein degradation of disease-causing deregulated protein targets.

Cell Biology and Regenerative MedicineSynthetic Biology - CRISPR The project is essential the construction of and testing/validation of a new synthetic biology tool using aspects of CRISPR systems to provide mammalian cells with a set of genetic instructions not encoded within their genomes. It will involve some molecular DNA cloning, design of new DNA sequences, and hopefully testing how well the new sequences function in cells. Nakamura Molecular Biology and Genetics
Cancer BiologyRegulation of telomere maintenance. Telomeres are specialized nucleoprotein structures at the end of linear chromosomes, essential for stable maintenance of eukaryotic genomes.
We currently have two possible GEMS student rotation projects. The first project will be based on the characterization of a novel RPA (Replication Protein A) mutant that fails to maintain telomeres and survive by circularizing chromosomes, even though telomerase is robustly recruited to telomeres. The second project will be characterizing various mutants that affect the transcription of long noncoding RNA (lncRNA) known as TERRA and cause telomere elongation.Rehman Molecular Biology and Genetics

Microbiology, Immunity and Inflammation
NeurobiologyProject 1: Development of human stem cell derived organoids to model lung disease
Project 2: The role of inflammation and infection in promoting Alzheimer's Disease
Project 3: Maternal-fetal inheritance of inflammatory stressProject 1: Working with stem cell derived progenitor cells of the lung epithelium, lung fibroblasts and lung vascular cells to create an organoid platform in which disease mechanisms can be studied. For the rotation, the primary goal will be for students to learn how to generate the organoids and assess the maturation of differentiated cells. Depending on the interest level and time, we can also subject the organoids to stressors and assess whether disease responses can be observed. A senior scientist will assist and guide the student to learn stem cell culture, differentiation and organoid assembly.
Project 2: Do repeated inflammatory stressors and bacterial or viral infections promote neurodegenerative disorders? Students will work with a neurobiologist in our lab and expose mice carrying human Alzheimer's disease mutations to stressors such as bacterial toxins or viral nucleic acid mimics and quantify how such stressors impact the blood brain barrier, premature senescence in certain brain areas and impair regeneration.
Project 3: How does inflammatory stress during pregnancy get transmitted to the next generation. Students will work with an immunologist to expose pregnant mice to bacterial toxins or viral stressors and then assess changes in the immune system, bone marrow and vasculature of the progeny. The assessment will focus on using flow cytometry to quantify changes in the hematopoietic and vascular lineages, as well as isolate cell populations for molecular studies.Segev Molecular Biology and Genetics Project 1: The role of Rab1 GTPase in membrane traffic coordination and neurological disease
Project 2: Aberrant Processing Bodies (PBs) accumulation and clearance in a neurodevelopmental disorderIn both projects we use cutting-edge molecular genetics, biochemistry and microscopy technologies in yeast and human cells, to study cell biological questions related to human disease.
In Project 1, we study the effect of depletion of Rab1 GTPase or its TRAPP activator on secretion, Golgi morphology and autophagy, all of which are associated with neurological disorders.
In Project 2, we study the effect of mutations associated with neurodevelopment in human patients on the formation of aberrant PBs and explore cellular pathways that can clear them.GEMS Information
