A Bioinspired Immunostimulatory System for Inducing Powerful Antitumor Immune Function by Directly Causing Plasma Membrane Rupture

ABSTRACT: Preparation of AMDs. 125 μM Ac4ManNAz were incubated with Raw 264.7 (~ 107 cells/dish) for 24, 48, and 72 h, followed by gentle washing with PBS or complete medium to produce Raw 264.7-Ac4ManNAz. Subsequently, Raw 264.7-Ac4ManNAz (~ 107 cells) were resuspended in PBS containing Alkynyl-Ce6(0.1 μM), ascorbic acid (0.2 μM) and CuSO4 (0.2 μM) and incubated for 1h at 37 °C. Then centrifuged (1000 rpm, 3 min) and washed 3 times with PBS to obtain precursor of AMDs. precursor of AMDs (~ 107 cells/tube, 1.0 ml) was immersed in liquid nitrogen, 24 h later, the frozen tubes were thawed at 37°C, centrifuged at 1500 rpm for 3 min, washed and resuspended by PBS to generate the AMDs (5 x 106 units/tube, 1.0 ml).

Global transcriptional response of Bordetella bronchiseptica after exposure to blood

Project description:B. bronchiseptica strain RB50 was grown in Stainer-Scholte (SS) broth at 37°C with shaking (220 rpm) overnight. Bacteria were subcultured at a starting OD600 of 0.1 into SS broth and grown at 37°C with shaking (220 rpm) up to an OD600 of 1.0. The cultures were pelleted and bacteria were washed twice with PBS buffer and equal aliquots were resuspended in SS broth (control) or in 100% sheep blood and incubated for 1 hour at 37°C.

RAW264.7 cells were treated with KDO, IFN beta and 8Br

Project description:RAW 264.7 cells were stimulated with KDO (100 ng/ml), IFN-β (300 pM) and/or 8-Br 100 μM. These ligands were applied individually or in combination with KDO for 60 min and 120 min. Total RNA was extracted using TriPure (Roche) following its protocol. Keywords: designed

Expression profiles of beta-hematin (BH)- or 4-hydroxy-2-nonenal (HNE)-treated RAW 264.7 cells

Project description:Hemozoin phagocytosis results in immunomodulation. In the present study, gene expression profiles were analyzed to identify transcriptional changes associated with two of the individual components of Hz in a model macrophage cell line. LPS-stimulated RAW 264.7 cells were exposed to the synthetic form of Hz, β-hematin (BH, 0.1 mg/mL) and HNE (35 μM) for 6 or 24 h. Keywords: variable treatment

Global gene transcriptional profiles of RAW 264.7 cells following the infection with Brucella abortus wild and mutant strains

Project description:We focused on whether transposon mutagenesis in Brucella abortus could induce difference in the trascriptional responses of RAW 264.7 cell infection model compared to the wild strain infected RAW 264.7 cells. The function of genes in Brucella abortus was analyzed through the identified differences in gene expression between RAW 264.7 cell infected with wild and mutant strains.

c756c936-c380-4c08-b0a3-f86f45a0393d - samples

Project description:The collection and use of tissue for this study had Melbourne Health institutional review board approval and patients provided written informed consent (Melbourne Health Local Project Number: 2016.087). Following the prostatectomy of 13 patients, ranging from 52 to 78 years of age and from CAPRA-S risk score of 0 (attributed to benign tissue samples, harvested from a site far from a low grade, low volume cancer) to 7 (Supplementary file 2), a four millimeter tissue core was collected from the prostate tumour site, conditional to histopathological verification66,67. If not otherwise specified, all procedures were carried out at 4 °C. Tissue blocks were washed in Phosphate-buffered saline (PBS) solution for 2 minutes and minced for 2 minutes with a scalpel. Homogenised tissue was added to a solution (total volume of 7 ml) composed by of 1 mg/ml collagenase IV (Worthington Biochemical Corp, USA), 0.02 mg/ml DNase 1 (New England Biolabs, USA), 0.2 mg/ml dispase (Merck, USA). The tissue homogenised was serially digested at 37 °C at 180 rpm, through three steps of 5, 10 and 10 minutes of duration, with the final 3 minutes dedicated to sedimentation at 0 rpm. After each digestion step, the supernatant was aspirated and filtered through a 70 μm strainer into a pre-chilled tube, diluting the solution with 15 ml of 2% bovine serum PBS to quench the enzymatic reaction. The resulting cumulative solution was then centrifuged at 1500 rpm for five minutes, with the supernatant collected and the cell pellet resuspended into 1 ml 2% PBS-serum prior to labelling (Fig. S1).

m6A profiles in shCTRL, shMETTL3 HeLa cells

Project description:Cells were washed with cold PBS twice and scraped from the plates, then centrifuged at 1000 rpm for 5 min to pellet cells. Washed cells were lysed with 400 L of cell lysis buffer (10 mM Tris-HCl pH7.5, 150 mM NaCl, 0.15% NP-40 and proteinase inhibitor cocktail) and incubated on ice for 10 min. The suspension was carefully add at the top of sucrose buffer (10 mM Tris-HCl pH7.5, 150 mM NaCl, 24% sucrose), and centrifuged at 3200g for 10 min to collect nuclear pellets. Pellets were resuspended in 250 L of Glycerol buffer (20 mM Tris-HCl pH7.5, 75 mM NaCl, 0.5 mM EDTA pH8.0, 50% glycerol), then then immediately add 250 μl Nuclear lysis buffer (10 mM Tris-HCl pH7.5, 300 mM NaCl, 7.5 mM MgCl2, 0.2 mM EDTA pH8.0, 1% NP-40, 1M urea). Mix by vortexing for 4 s and incubate on ice for 2 min. Centrifuge the lysate at 13,000 × g for 2 min to precipitate the chromatin–RNA complex. Brieﬂy rinse the chromatin pellets with PBS-EDTA. RNA was extracted with Trizol reagent. RNA libraries were prepared according to manual of SMARTer smRNA-Seq Kit for Illumina (Clontech, 635031).
