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. Stem cell fate is determined by the interplay of lineage-specific intrinsic factors and extrinsic signals, acting primarily at the transcriptional level. Selected for Faculty of 1000 (Factor 9 Exceptional). The EMBO journal 20 (20), 5759-5768, 2001. Selected for Faculty of 1000 (Factor 3 Recommended). This plasticity is the result of the existence of very efficient input pathways that convey the external signals into the core oscillator machinery. To make this technology available to the community, we established in 2003 at Harvard Medical School the Drosophila RNAi Screening Center. 369.

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. 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. as achieved by mapping signal pathway activities in various cell types), and the physiological roles of various cells.

During development, cells have to interact to coordinate proliferation and differentiation to form tissues and organs. This plasticity is the result of the existence of very efficient input pathways that convey the external signals into the core oscillator machinery. How do circRNAs work at the molecular level? Eric joined the Bandopadhayay Lab in 2020 where he is working to characterize driver mutations found in pediatric brain tumors and developing new approaches to treat these children with targeted therapies. We have taken a number of approaches to address the spatial and temporal regulation of signaling pathway activities in the gut epithelium. Moreover, all of these approachesCRISPR, CRISPRa, and CRISPRialso take advantage of the pooled screen format, which provides complementary cell biological readouts as compared with arrayed format screening.

Selected for Faculty of 1000 (Factor 6 Must Read). Additionally, many of the mechanisms by which growth factortriggered signaling events intersect with cell metabolism, which is regulated by nutrients, hormones and stress, remain to be identified. We now have available for screening: genome-wide RNAi libraries and subset RNAi libraries (Kinase/Phosphatase; Ubiquitination; Transmembrane proteins; Transcription factors; RNA-binding proteins; Autophagy-related proteins; G-protein coupled receptors; Membrane-bound organelles; and Orthologs of human proteins for which there are FDA-approved drugs); Overexpression libraries (UAS-ORFs); and reagents for both gain-of-function (UAS-miR) and loss-of-function (UAS-miR-sponges) miRNA screens. * Corresponding authors.

B.S., University of Barcelona, Spain Ph.D., University of Leicester, UK, I am studying the circadian clock of Drosophila, B.S. 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. We continue to evaluate and create new methods for genome engineering. Lacadie S.A., Tardiff D.F., Kadener S. and Rosbash M.

Nogues G., Kadener S., Cramer P., Bentley D. and Kornblihtt A.R. Circadian clocks are also exceptionallyplasticas they can quickly and specifically adjust to specific environmental cues. leptin), neural development, and behavior are conserved. Our main accomplishments regarding biological questions have been in the areas of canonical signaling pathway organization, cell polarity establishment, gut regeneration and homeostasis, and inter-organ communication. Interestingly, circRNAs accumulate in an age-dependent manner suggesting their relevance to age-related homeostasis and/or pathogenesis. Eric received his MS in biomedicine from Uppsala University, Sweden in 2010. Circadian clocks are remarkably robust: they are able to keep time without timing cues and are resilient to large variations in environmental conditions. Circadian clocks are remarkably robust: they are able to keep time without timing cues and are resilient to large variations in environmental conditions. Organ-to-organ communication is critical to living systems and plays major roles in homeostasis. Lerner I. In October 2021, Anna defended her PhD thesis (and Mimi had the honor of being her faculty opponent!!). She makes a mean pour over coffee, and her favorite animal is a tie between a sloth and a quokka. Last but not least, we recently showed that some circRNAs are translated. Third, more recently we used single-cell RNAseq (scRNAseq) to describe all the cell types and their transcriptomes in the Drosophila gut. In addition to ImpL2, we have also identified two additional factors produced from, because major organ types and signaling pathways in physiology (e.g. 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 . Olivia received her B.A. These lines can be combined with tissue-specific delivery of Cas9 to generate clones of cells (mosaics) or combined with germline expression of Cas9 to generate null mutations. In addition to ImpL2, we have also identified two additional factors produced from yki-gut tumors that contribute to tissue wasting: the Pvr receptor tyrosine kinase ligand Pvf1 and the IL6-like cytokine Unpaired 3 (Upd3). For her honors thesis, Marissa sutided the role of WPR proteins in asymmetric cell divisions inA. thalianaroots. We are particularly interested on the role of circular RNAs (circRNAs) at the molecular and neural levels as well as the mechanisms underlying circadian clocks. Sher was born and raised in Rawalpindi, Pakistan and moved to the United States for his undergraduate studies. Acquiring answers to these fascinating questions requires a deep understanding of the mechanisms by which cells integrate signals received from their inner selves, neighboring cells, other organs and the environment. Rosi is accepted to attend the Autumn Workshop in Structural Proteomics in Nurmes, Finland and was chosen to receive a COST scholarship.

Title. Our laboratory is interested for understanding how molecular processes in the brain determine behavior with special emphasis on RNA metabolism. I am analyzing the effect of circRNA on aging in Drosophila, majoring in biochemistry and neuroscience. Over the years, we have added a number of screening reagents and developed bioinformatics tools to improve the platform. Strikingly, these phenotypes are reminiscent of the pathophysiology of cystic fibrosis (CF), as in CF the non-functional CF transmembrane conductance regulator (CFTR) increases ENaC activity resulting in chronic dehydration of the intraluminal surface liquid in organs such as kidney, colon, lung and sweat glands.
