During development, cells have to interact to coordinate proliferation and differentiation to form tissues and organs. Second, we identified 53 transcription factors, specifically expressed or enriched in the ISCs, and are characterizing how they cooperate to integrate signal inputs. Im an undergraduate in the Class of 2023 majoring in Chemical Biology at Brandeis. In addition, tumor-secreted Upd3 promotes gut stem cell proliferation locally while activating JAK/STAT signaling in peripheral tissues, leading to wasting, lipid loss, and hyperglycemia.

Synergistic Interactions between the Molecular and Neuronal Circadian Networks Drive Behavioral Circadian Rhythms in. More. In the Bandopadhay Lab, Marissa is working to study drivers of Diffuse Midline Gliomas, including the mechanisms through which MYC isoforms are activated. We previously developed a recombination-mediated cassette exchange (RMCE) system that enables pooled CRISPR screening in Drosophila cells, as well as bioinformatics tools for identifying sgRNA designs for mosquitos and mosquito cell lines. Understanding how circadian rhythms are generated, maintained, and adapted to changing conditions is key, as several diseases such as cancer and depression are associated with misalignment of the circadian clock with the environment. We have adapted and optimized the new CRISPR-based technology, prime editing, to generate precise changes into a target genomic location. Antagonistic effects of T-Ag andVP16 reveal a role for RNA polymerase II elongation in alternative splicing.

In addition, skeletal muscles produce various myokines that influence metabolic homeostasis, lifespan, and the progression of age-related diseases and aging in non-muscle tissues. Chikne V.*, Doniger T.*, Bartok O. A polar mechanism coordinates different regions of alternative splicing within a single gene. In a collaboration with Sebastian Kadener's 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. This plasticity is the result of the existence of very efficient input pathways that convey the external signals into the core oscillator machinery. Fun fact: Leslie played basketball through college and is now an avid cyclist. Now, in an article published in the journal Molecular Cell, the lab of Dr. Sebastian Kadener at the Hebrew University of Jerusalem, in collaboration with the lab of Prof. Nikolaus Rajewsky at the . 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. He then pursued a PhD in chemistry at Caltech (17) under the mentorship of Dr. Jackie Barton.

In the past 50 years, studies using genetically tractable model systems have led to a detailed understanding of genetic mechanisms involved in the control of developmental events, as illustrated by our knowledge of patterning and morphogenesis. Control of alternative pre-mRNA splicing by RNA Pol II elongation: faster is not always better. In the Bandopadhayay Lab, Leslie has been able to combine her background in cancer cell metabolism with genomic, transcriptomic and gene editing approaches to understand the biology of pediatric brain tumors and elucidate mechanisms of resistance to targeted therapies such as BET-bromodomain inhibition.

PubMed ID: 31702556 Jess received her BS in Biological Sciences with Honors in Neurobiology at Stanford University in 2008 before joining the Medical Scientist Training Program at Stanford University School of Medicine, receiving her MD and PhD in 2015. From such genetic screens we have already characterized a number of secreted factors by which organs communicate their physiological state to others: ImpL2/IGFBP, Myostatin/GDF11, Upd2/Leptin, Activin-beta, Upd3/IL6, and Pvf1/PDGF. Now the stage is set for the most exciting questions, which we are currently working in the lab, by combining molecular, computational and RNA biology with advances techniques in genetics and neurosciences. using proximity labeling to identify all proteins secreted by the tumors. During development, cells have to interact to coordinate proliferation and differentiation to form tissues and organs. Moreover, in 2019, we were funded to function as the Drosophila Research and Screening Center-Biomedical Technology Research Resource (DRSC-BTRR), which focuses on development of new screening and other technologies. We renamed the center DRSC/TRiP-Functional Genomics Resources to better represent our current capabilities. She also loves bagels and is always on the hunt for the best bagel.
