Before joining the Bando Lab, John worked as a High Frequency Trader. Andranik Ivanov and Sebastian Meczmack (Prof. Rajewsky's . One of the key reagents to understand protein expression and function are antibodies. Among the next significant questions to address are how complex phenotypes arise in the context of the whole organism and how the programs regulating these phenotypes are influenced by genetic background and environment. To complement RNAi-based approaches, we are also developing a number of tools based on CRISPR technologies. Rabin A, Zaffagni M, Ashwal-Fluss R, Patop IL, Jajoo A, Shenzis S, Carmel L, Kadener S.

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. These esg>yki gut tumors induce organ wasting by secreting the insulin binding protein ImpL2 into the hemolymph, which reduces insulin signaling in peripheral tissues. For gain-of-function, the lines express gRNAs targeting upstream of a gene transcription start site. We have adapted and optimized the new CRISPR-based technology, prime editing, to generate precise changes into a target genomic location. Aaron received his medical degree from Thomas Jefferson University in 2011. We chose to use peripheral blood monocytes as source material for gene expression profiling, because (a) blood is an easily accessible source of human cells and (b) monocytes constitute a homogenous blood cell population and have been shown to possess a high-amplitude circadian clock ( 24, 25) in contrast to other PBMCs, such as B or T cells. Additional unpublished work from my lab demonstrates that a subset of circRNAs is translated. What are the key functions of these molecules in the brain and during aging?

Informative set of videos on insect physiology and endocrinology: New paper: In addition to her passion for medicine and science, Jess is also passionate about advocacy for science. These studies have allowed us to better characterize what cell types are present in different gut regions and provide us with new powerful data sets with which we can better characterize the transcriptional networks that define lineage relationships among cell types, cell-cell interactions among cell types (i.e. Antibodies allow protein visualization by immunostaining, biochemical study by immunoprecipitation and western blot, and proteomic study by IP-MS. One point of focus for DRSC-BTRR efforts is establishment of CRISPR pooled screening in cell lines from mosquito vectors of infectious diseases. 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.
