The tagged endogenous proteins can then be isolated for further analysis by MS. To analyze protein-protein interactions or identify components that localize to discrete subcellular compartments, we developed tools based on APEX, an engineered ascorbate peroxidase derived from plants, and BioID, a mutant form of the biotin ligase BirA from E coli and demonstrated their use for in vivo studies. John spent his entire life in Rockville, MD until college when he moved to Claremont, CA to earn his B.S. Im a Masters student studying the expression of Ultradian Genes and their role in Canton-S flies. Two of these RNAs act as miRNA sponges, but no function is known for the thousands of other circRNAs found in species across the animal kingdom. UAS-gypsy structure and functional test. Following our identification of adult Drosophila intestinal stem cells (ISCs), we used this system to characterize genes and pathways important for gut homeostasis and in particular, to analyze crosstalk among signaling pathways.

Send us removal request. Finally, as an alternative to RNAi for partial loss-of-function screens using a Cas system, we have shown that Cas13 is an effective tool for CRISPRi in Drosophila cells. Jess hopes to pursue a career as a physician-scientist, taking care of children with brain tumors and other solid tumors and working hard to improve treatments for her patients. Jens joined the Bando Lab in 2023 as a visiting graduate student to understand how distinct histone mutations influence gliomagenesis and also aims to exploit the dependence of pLGGs on the MAPK pathway. Hanan M., Soreq H. and Kadener S. CircRNAs in the brain. Fun fact: Like many Swedish people, Eric has completed Vasaloppet, a 60-mile cross-country skiing race (twice!). We use Drosophila as a model system to characterize the mechanisms underlying communication between cells, tissues, and organs.

Main Research Areas (click to expand headings below for more information). Michael earned a BA in cellular biology and neuroscience from Rutgers University. A defining property of circadian clocks is temperature compensation, characterized by the resilience of circadian free-running periods against changes in environmental temperature. Rosi is attending the structural MS workshop in Finland. Nov, 2017. Following. I am interested in studying circular RNA formation. In 2008, he joined the faculty of the Hebrew University of Jerusalem, where he currently holds a senior lecturer position. Further, our work and that of others has suggested functions of these moleculesin vivo. An early ancestor in the evolution of splicing: a.

Molecular Neurobiology and RNA metabolism. Despite the importance of antibodies in biology study, antibodies are not available for most fly proteins. With this advance, we hope to enable the mosquito community to easily perform genome-wide loss- or gain-of-function screens in cells, for example to discover entry and infection mechanisms of pathogens and drugs, as well as to aid in the functional annotation of mosquito genomes. For his senior clinic project, John worked with HRL Laboratories to create an algorithm for electrostatically tuning quantum dots using neural networks for quantum computers. We showed that their translation is mediated by IRES-like sequences, is enhanced in response to starvation and happens in association with membranes and in synapses. Nucleic Acids Research47(11): e95; 1-16 (2017). Proximity labeling utilizes enzymes that generate reactive radicals to covalently tag neighboring proteins. Cs. Hu, Comjean, Attrill, Antonazzo, Jim Thurmond, Li, Chao, Mohr, Brown, Perrimon She also loves sleeping in, making guacamole, and reading about art history.

In mature animals, cells and organs interact to maintain homeostasis and coordinate their physiological roles. This collection is available to the community through the Bloomington Drosophila Stock Center. The current model postulates that circadian oscillators keep time by complex transcriptional and post-transcriptional feedback loops. We are now adapting the pooled-format CRISPR screening approach for use in cell lines from medically relevant mosquito species. Sebastian Kadener Prof. Nac. She makes a mean pour over coffee, and her favorite animal is a tie between a sloth and a quokka. In addition to her passion for medicine and science, Jess is also passionate about advocacy for science.

Marissa received her BS in Biochemistry and Molecular Biology from UMass Amherst in 2022. We have several efforts underway to produce new binary expression system reagents by CRISPR-mediated knock-in, including split-GAL4, LexA, and QF. For example, we identified a number of ion channels that either directly or indirectly regulate stem cell proliferation. Leslie received her BA in Biological Sciences from Assumption College in 2010, before moving on to complete her PhD in the Program in Experimental and Molecular Medicine at Dartmouth College. Software. Associate Professor, Brandeis University. During her time at Brandeis, Maddie worked in the lab of Sebastian Kadener studying RNA metabolism and the circadian rhythm. In the Bandopadhayay Lab, Anna will be expanding her skills to apply genomic approaches to understand the mechanisms through which gliomas develop, and to develop strategies to overcome therapeutic resistance. Moreover, we also showed that the neural and molecular circadian systems compensate and interact with each other. Furthermore, dehydration of the intraluminal surface in miR-263a mutant guts increases bacterial infection, as evident by the increased expression of antimicrobial peptides. We are now using this tool to establish sensors of each signaling pathway involved in gut homeostasis, and will use these reagents to examine pathway crosstalk. She received her BA in Molecular and Cell Biology from the University of California, Berkeley in 2019. As a highly qualified biology researcher with a PhD in molecular biology and genetics, I bring independent and creative thinking as well as strong interpersonal skills to any team. Fun fact: In his native language of Urdu, Shers full name translates to lion/tiger brave. This dual reporter can be used in either fixed or live tissues to monitor spatio-temporal activity of signaling pathways at an unprecedented resolution. ), we have identified and validated novel mechanisms of how stem cells adjust their rate of proliferation/differentiation to meet the demand for tissue regeneration. In a collaboration with Sebastian Kadeners lab at Brandeis, we generated a new set of PspCas13b and RfxCas13d expression constructs that can be used to target RNA in cells and in vivo.
