In recent years, a number of tools have become available for remotely activating neural circuits in Drosophila. Despite widespread and growing use, very little work has been done to characterize exactly how these affect activity identified fly neurons. Using the GAL4-UAS system, we expressed blue light–gated Channelrhodopsin-2 (ChR2) mutated form ChR2 (H134R-ChR2) motor sensory neurons Drosophila third-instar locomotor circuit. Neurons expressing H134R-ChR2 show enhanced responses light...
Glioma growth is driven by signaling that ultimately regulates protein synthesis. Gliomas are also complex at the cellular level and involve multiple cell types, including transformed reactive cells in brain tumor microenvironment. The distinct functions of various types likely lead to different requirements regulatory paradigms for Proneural gliomas can arise from transformation glial progenitors proliferate via mitogenic affects translation. To investigate translational regulation this...
Importance Appendiceal adenocarcinoma is a rare tumor, and given the inherent difficulties in performing prospective trials such disease, there are currently minimal high-quality data to guide treatment decisions, highlighting need for more preclinical clinical investigation this disease. Objective To prospectively evaluate effectiveness of fluoropyrimidine-based systemic chemotherapy patients with inoperable low-grade mucinous appendiceal adenocarcinoma. Design, Setting, Participants This...
Ribosome profiling has emerged as a powerful tool for genome-wide measurements of translation, but library construction requires multiple ligation steps and remains cumbersome relative to more conventional deep-sequencing experiments. We report new, ligation-free approach ribosome that does not require ligation. Library can be completed in one day with little 1 ng purified RNA footprints. apply mouse brain tissue identify new patterns cell type-specific translation test its ability...
Abstract Purpose: Appendiceal adenocarcinoma (AA) remains an orphan disease with limited treatment options for patients unable to undergo surgical resection. Evidence supporting the efficacy of combined VEGF and PD-1 inhibition in other tumor types provided a compelling rationale investigating this combination AA, where immune checkpoint inhibitors have not been explored previously. Experimental Design: We conducted prospective, single-arm phase II study evaluating safety atezolizumab...

Small bowel adenocarcinoma (SBA) is a rare malignancy marked with poor prognosis. The cellular and proteomic heterogeneity within the tumor immune microenvironment (TIME) of SBA likely driver prognosis, disease progression response to therapy. We have addressed major gap in knowledge TIME using highly multiplexed, protein imaging tumor-immune ecosystem generating comprehensive, single-cell level, spatial, atlas > 600,000 cells from 136 matched normal samples clinically genomically...
Here we incorporate recent advances in Drosophila neurogenetics and “optogenetics” into neuroscience laboratory exercises. We used the light-activated ion channel channelrhodopsin-2 (ChR2) tissue-specific genetic expression techniques to study neural basis of behavior larvae. designed implemented exercises using inexpensive, easy-to-use systems for delivering blue light pulses with fine temporal control. Students first examined behavioral effects activating glutamatergic neurons larvae then...
The Drosophila larval neuromuscular preparation has proven to be a useful tool for studying synaptic physiology1,2,3. Currently, the only means available evoke excitatory junctional potentials (EJPs) in this involves use of suction electrodes. In both research and teaching labs, students often have difficulty maneuvering manipulating type stimulating electrode. present work, we show how remotely stimulate at NMJ without By expressing channelrhodopsin2 (ChR2) 4,5,6 motor neurons using...
Abstract Cancer stem cells (CSC) play a critical role in metastasis, relapse, and therapy resistance colorectal cancer. While characterization of the normal lineage cell development intestine has led to identification many genes involved induction maintenance pluripotency, recent studies suggest significant heterogeneity CSC populations. Moreover, while canonical cancer marker have been identified, ability use these classical markers annotate stemness at single-cell level is limited. In this...
Abstract Protein synthesis is dysregulated in many diseases, but we lack a systems-level picture of how signaling molecules and RNA binding proteins interact with the translational machinery, largely due to technological limitations. Here present riboPLATE-seq, scalable method for generating paired libraries ribosome-associated total mRNA. As an extension PLATE-seq protocol, riboPLATE-seq utilizes barcoded primers pooled library preparation, additionally leverages anti-rRNA ribosome...
