Project description:Natural Killer (NK) cell is a valuable tool for immunotherapy in cancer treatment, both the cultured cell line NK92 and primary NK cells are widely studied and used in the research and clinical trials. Clinical observations witnessed the improvement of patients’ NK cells in terms of cell counts and cytotoxic activity upon dasatinib treatment, an approved drug against CML and Ph+ ALL. Several studies supported the clinical observations, yet others argued a detrimental effect of dasatinib on NK cells. Due to the complex conditions in different studies, the definite influence of dasatinib on NK92 and primary NK cells remains to be settled. Here, we used a well-defined in vitro system to evaluate the effects of dasatinib on NK92 cells and peripheral blood (PB)-NK cells. By coculturing NK cells with dasatinib to test the cell counts and target cell killing activities, we surprisingly found that the chemical influenced oppositely on these two types of NK cells. While dasatinib suppressed NK92 cell proliferation and cytotoxic activity, it improved PB-NK killing tumor cells. RNA-seq analysis further supported this finding, uncovering several proliferating and cytotoxic pathways were responding invertedly between them. Our results highlighted an intrinsic difference between NK92 and PB-NK cells and may build clues to understand how dasatinib interacts with NK cells in vivo.

Project description:We compared transcriptome of different types of NK cells including obtained from peripheral Blood (PB-NK), derived from human ES cell, H9-NK, derived from human iPSC (iPSC-NK), derived from CD34+ cells from umbilical cord blood (UCB-NK), NKcell line (NK92) and 3 cancer cell lines (K562, Raji and Jurkat). When comparing the similarity of the NK cells populations by the number of differentially expressed genes to iPSC NK cells, there were the fewest differentially expressed genes in the comparison with the UCB NK cells, followed by the PB-NK cells, followed by the H9 embryonic stem cell derived-NK cells and lastly by the NK92 cell line.

Project description:PPMX-T003, an humanized anti-transferrin receptor 1 inhibitory antibody, has anti-neoplastic potential against mature NK cell neoplasms. However, its molecular mechanism is not elucidated. To investigate, we performed RNAseq of NK92 cells treated with PPMX-T003 to obtain defferentially expressed gene signature and compared it to those of well-known anti-neoplastic agents for prediction of similarity in transcriptomic change.

Project description:YT and NK92 cells are EBV-infected lymphoma cells of NK- cell origin. YT cells have weaker expression of T-bet and IFNg than NK92 cells. However, this data set shows that both cell lines have similar mRNA levels, implying post-transcriptional regulations.

Project description:YT and NK92 cells are EBV-infected lymphoma cells of NK- cell origin. YT cells have weaker expression of T-bet and IFNg than NK92 cells. However, this data set shows that both cell lines have similar mRNA levels, implying post-transcriptional regulations. Affymetrix chips (Human Genome U133 plus 2.0) were used for a genome-wide screen of transcriptional profiles on YT and NK cells. Hybridization and washing of the arrays were done according to the GeneChip® Expression Analysis Technical Manual from Affymetrix. The arrays were scanned with GenePix 4000B (Molecular Devices, Sunnyvale, CA.), and the data were extracted with Affymetrix Microarray suite (MAS) software.

Project description:The aim of the study was to determine the effect of natural killer (NK) cells on the global gene expression in Plasmodium falciparum. FCR3-CSA-infected red blood cells (RBCs) were co-cultured for 24h with NK92. Prior to RNA extraction, the parasitized RBCs were separated via Ficoll from the lymphocyte fraction. Control cultures of parasites without NK cells were cultivated in parallel. In addition, the effect of the separation method was determined via a Ficoll control culture of FCR3-CSA that was passed over a Ficoll gradient. All three treatments were performed in triplicate. The RNA was reverse-transcribed and hybridized onto microarrays.

Project description:Human NK cells activity against cancer cells is deeply suppressed by TGF-β1, an immunomodulatory cytokine that is released and activated in the tumor microenvironment. Moreover, our previous data showed that TGF-β1 modifies the chemokine receptor repertoire of NK cells. In particular, it decreases the expression of CX3CR1 that drives these effectors toward peripheral tissues, including tumor sites. In order to identify possible mechanisms mediating chemokine receptors modulation, we analyzed the miRNA profile of TGF-β1-treated primary NK cells. The analysis pointed out miR-27a-5p as a possible modulator of CX3CR1. We demonstrated the functional interaction of miR-27a-5p with the 3’ untranslated region (3’UTR) of CX3CR1 mRNA by two different experimental approaches: by the use of a luciferase assay based on a reporter construct containing the CX3CR1 3’UTR and by transfection of primary NK cells with a miR-27a-5p inhibitor. We also showed that the TGF-β1-mediated increase of miR-27a-5p expression is a consequence of miR-23a-27a-24-2 cluster induction. Moreover, we demonstrated that miR-27a-5p down-regulates the surface expression of CX3CR1. Finally we showed that Neuroblastoma cells induced in resting NK cells a downregulation of the CX3CR1 expression that was paralleled by a significant increase of miR-27a-5p expression. Therefore, the present study highlights miR-27a-5p as a pivotal TGF-β1-induced regulator of CX3CR1 expression.

Project description:Clostridium acetobutylicum is a Gram positive, endospore forming firmicute that has been known as the model organims for ABE (acetone-butanol-ethanol) fermentation. With its ability to consume a wide variety of substrates, C. acetobutylicum carries out a biphasic ABE fermentation, which consists of the acidogenic growth phase with the formation of butyric acid and acetic acid, followed by the solventogenic stationary phase with the formation of acetone, butanol and ethanol, characterised by the reassimilation of acids. The production butanol is of renewed ineterest both as a potential biofuel and bulk chemical production. Both butanol and butyric acid posses toxic characteristic and here, we focus on understanding and modeling the stress response of C. acetobutylicum to one of the two important toxic metabolites: butyric acid.
