MRNA expression profiles in YT and NK92 cells

ABSTRACT: 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.

mRNA expression profiles in YT and NK92 cells

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 GeneChipÂ® 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.

miRNA expression profiles in YT and NK92 cells

Project description:The miRNA expression profiles of of EBV-infected YT and NK92 cells are compared. YT cells have weaker expression of T-bet and IFNg than NK92 cells. It was found that the EBV-encoded miR-BART20-5p inhibits the expression of T-bet and IFNg in YT cells. Approximately 100 ng total RNAs from YT and NK92 cells were used as the input. The GeneChip miRNA 2.0 array from Affymetrix, including probes for 44 EBV-encoded miRNAs and 1105 human miRNAs, was used. The experiments were performed in the microarray core laboratory of National Health Research Institute, Taiwan.

NK92 cells and peripheral blood NK cells respond oppositely upon dasatinib treatment

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.

Expression data of PRDM1α or empty vector-transduced NK92 or KHYG1 cell lines

Project description:CD25 (IL2RA) is a subunit of IL2 receptor complex, which determines the sensitivity of the receptor to IL2. Here, we investigated whether PRDM1, a transcriptional repressor implicated as a tumor suppressor in NK cell malignancies, directly represses CD25 (IL2RA). Using ChIP-seq, we identified a direct binding site of PRDM1 within 1st intron of CD25 (IL2RA) in activated primary human NK cells. We used DNA microarrays on two PRDM1α transduced NK cell lines (i.e. NK92 and KHYG1) to address whether PRDM1 transcriptionally represses CD25.

Transcriptome analysis of NK92 teated with PPMX-T003 for connectivity scoring analysis

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.

Time kinetics of gene expression in NK92 cells after Plasmodium falciparum-iRBC encounter

Project description:To study the effect of Plasmodium falciparum-infected erythrocytes on gene expression in NK92 cells, microarray analysis after 6, 12 and 24 hours of co-culture with either uRBC or iRBC was performed. The aim was to identify pathways in NK92 cells that are switched on after iRBC encounter in a time-dependent manner that will help to understand the mechanisms in innate immune defenses against Plasmodium falciparum infection. Variation in gene expression of NK92 cells was determined after 6, 12, and 24 hours of co-culture with either infected or uninfected RBC compared to timepoint 0 (start of co-culture, untreated control). All experiments were done in triplicate, that means that samples were collected in 3 different experiments (A, B, and C) each time after 0, 6, 12 and 24 hours of co-culture.

Quantitative Analysis of different NK cell types Transcriptomes

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.
