Exosomes Confer Chemoresistance to Pancreatic Cancer Cells By
FULL PAPER British Journal of Cancer (2017) 116, 609–619 | doi: 10.1038/bjc.2017.18 Keywords: chemoresistance; exosomes; pancreatic cancer; ROS; microRNA Exosomes confer chemoresistance to pancreatic cancer cells by promoting ROS detoxification and miR-155-mediated suppression of key gemcitabine-metabolising enzyme, DCK Girijesh Kumar Patel1, Mohammad Aslam Khan1, Arun Bhardwaj1, Sanjeev K Srivastava1, Haseeb Zubair1, Mary C Patton1, Seema Singh1,2, Moh’d Khushman3 and Ajay P Singh*,1,2 1Department of Oncologic Sciences, Mitchell Cancer Institute, University of South Alabama, Mobile, AL, USA; 2Department of Biochemistry and Molecular Biology, College of Medicine, University of South Alabama, Mobile, AL, USA and 3Department of Interdisciplinary Clinical Oncology, Mitchell Cancer Institute, University of South Alabama, Mobile, AL, USA Background: Chemoresistance is a significant clinical problem in pancreatic cancer (PC) and underlying molecular mechanisms still remain to be completely understood. Here we report a novel exosome-mediated mechanism of drug-induced acquired chemoresistance in PC cells. Methods: Differential ultracentrifugation was performed to isolate extracellular vesicles (EVs) based on their size from vehicle- or gemcitabine-treated PC cells. Extracellular vesicles size and subtypes were determined by dynamic light scattering and marker profiling, respectively. Gene expression was examined by qRT-PCR and/or immunoblot analyses, and direct targeting of DCK by miR-155 was confirmed by dual-luciferase 30-UTR reporter assay. Flow cytometry was performed to examine the apoptosis indices and reactive oxygen species (ROS) levels in PC cells using specific dyes. Cell viability was determined using the WST-1 assay. Results: Conditioned media (CM) from gemcitabine-treated PC cells (Gem-CM) provided significant chemoprotection to subsequent gemcitabine toxicity and most of the chemoresistance conferred by Gem-CM resulted from its EVs fraction. -

High RRM1-expression associates with gemcitabine-resistance in various cancers and RRM1 inhibition may provide novel cancer treatment approaches. Our study eluci- dates how RRM1 inhibition affects cancer cell proliferation and influences gemcitabine-resistant bladder cancer cells. Of nine bladder cancer cell lines investigated, two RRM1 highly expressed cells, 253J and RT112, were selected for further experimentation. An RRM1-targeting shRNA was Citation: Zhang, X.; Taoka, R.; Liu, cloned into adenoviral vector, Ad-shRRM1. Gene and protein expression were investigated using D.; Matsuoka, Y.; Tohi, Y.; Kakehi, Y.; real-time PCR and western blotting. -

Expression and Characterisation ofa Gene Enc oding RbpD, an RNA- Bind ing Protein in Anabaena sp. strain PeC 7120 by Rob in lee Tremblay A lhesis submitted to the Scltool of Graduale Studies in partial fulfilment of the requirements fOl" the degree of Master of Science Department of BiochemistrylFacultyof Science Memorial University of Newfoundland January 2000 SI.JOM'S Newfoun dland Abs t ra ct The RNA-binding protein RbpD, from the cyano bacterium Anaba ena sp, strain Pe C 7120 was expressed in £Sch~ ric h ia coli and successfully purified using me IMPACT I system (New England Biolabs). The rbp D gene was cloned into the pCYBt expre ssion vector by using polymerase chain reaction to introduce Ndel and SapI restriction sites at the 5' end 3' ends of the gene respect ively. The 3'.-end mutagenesis also chan ged the stop codon into a cysteine codon. The resulting gene encoded a fusion protein consisting of RbpD, the Saccharomyces cerev isiae VMA intein and a chitin binding domain.. Expressi on of the fusion protein was observed in £ coli strain MCI061 but Western blot analysis using an intein-directed ant ibody indicated that significant in vivo fmeln-direcred splicing of the fusion protein occurred. We were unable to eliminate this problem; no fusion protein expression was observed in 8 other E coli strains tested. Wild -type RbpD was purified following binding of the fusion protein 10 a chitin column and overnight cleavage in the presence of a reducing agent, dlthicthrehc l. A number of modifications to the manufacturer' s purification protocol were found to be necessary for success ful purification. -
Taurine Reduction in Anaerobic Respiration of Bilophila Wadsworthia RZATAU

COOK* Faculta¨t fu¨r Biologie, Universita¨t Konstanz, D-78434 Konstanz, Germany Received 7 November 1996/Accepted 18 February 1997 Organosulfonates are important natural and man-made compounds, but until recently (T. J. Lie, T. Pitta, E. R. Leadbetter, W. Godchaux III, and J. R. Leadbetter. Arch. Microbiol. 166:204–210, 1996), they were not believed to be dissimilated under anoxic conditions. We also chose to test whether alkane- and arenesulfonates could serve as electron sinks in respiratory metabolism. We generated 60 anoxic enrichment cultures in mineral salts medium which included several potential electron donors and a single organic sulfonate as an electron sink, and we used material from anaerobic digestors in communal sewage works as inocula. None of the four aromatic sulfonates, the three unsubstituted alkanesulfonates, or the N-sulfonate tested gave positive enrichment cultures requiring both the electron donor and electron sink for growth. Nine cultures utilizing the natural products taurine, cysteate, or isethionate were considered positive for growth, and all formed sulfide. Two clearly different pure cultures were examined. Putative Desulfovibrio sp. strain RZACYSA, with lactate as the electron donor, utilized sulfate, aminomethanesulfonate, taurine, isethionate, and cysteate, converting the latter to ammonia, acetate, and sulfide. Strain RZATAU was identified by 16S rDNA analysis as Bilophila wadsworthia. In the presence of, e.g., formate as the electron donor, it utilized, e.g., cysteate and isethionate and converted taurine quantitatively to cell material and products identified as ammonia, acetate, and sulfide. -

Mitigation of ALS Pathology by Neuron-Specific Inhibition of Nuclear Factor Kappa B Signaling
The Journal of Neuroscience, June 24, 2020 • 40(26):5137–5154 • 5137 Neurobiology of Disease Mitigation of ALS Pathology by Neuron-Specific Inhibition of Nuclear Factor Kappa B Signaling Kallol Dutta,1 Sai Sampath Thammisetty,1 Hejer Boutej,1 Christine Bareil,1 and Jean-Pierre Julien1,2 1CERVO Brain Research Centre, Québec City, Québec G1J 2G3, Canada, and 2Department of Psychiatry and Neuroscience, Université Laval, Québec City, Québec G1V 0A6, Canada To investigate the role of neuronal NF-jB activity in pathogenesis of amyotrophic lateral sclerosis (ALS), we generated trans- genic mice with neuron-specific expression of a super-repressor form of the NF-jB inhibitor (IjBa-SR), which were then crossed with mice of both sexes, expressing ALS-linked gene mutants for TAR DNA-binding protein (TDP-43) and superoxide dismutase 1 (SOD1). Remarkably, neuronal expression of IjBa-SR transgene in mice expressing TDP-43A315T or TDP-43G348C mice led to a decrease in cytoplasmic to nuclear ratio of human TDP-43. The mitigation of TDP-43 neuropathology by IjBa-SR, which is likely due to an induction of autophagy, was associated with amelioration of cognitive and motor deficits as well as reduc- tion of motor neuron loss and gliosis. Neuronal suppression of NF-jB activity in SOD1G93A mice also resulted in neuroprotection with reduction of misfolded SOD1 levels and significant extension of life span. The results suggest that neuronal NF-jB signaling constitutes a novel therapeutic target for ALS disease and related disorders with TDP-43 proteinopathy. Key words: amyotrophic lateral sclerosis; frontotemporal dementia; IjB suppressor; NF-jB; superoxide dismutase; TDP-43 Significance Statement This study reports that neuron-specific expression of IkB super-repressor mitigated behavioral and pathologic changes in transgenic mouse models of amyotrophic lateral sclerosis expressing mutant forms of either Tar DNA-binding protein 43 or superoxide dismutase. -
