microRNA expression profiling in Natural Killer exosomes

Project description:Natural Killer (NK) cells are important components of the immune system in the defense against tumor transformation. They release exosomes containing proteins and nucleic acids, including microRNAs (miRNAs) that play a role in the anti-tumor NK cell functions since they are able to recognize and kill cancer cells. In this study, we explored the miRNA content of NK exosomes by microarray as compared to their cellular counterpart and we identified a small subset of miRNAs highly expressed in NK exosomes.

Expression profiling of Natural killer B cells

Project description:Investigation of global gene expression levels between B cells, Natural killer cells and Natural killer B cells Gene expression profiling using sorted B cells, Natural killer cells and Natural killer B cells from WT mouse spleen. Total RNA extracted from WT cells were quantified by the NanoDrop ND-1000 and RNA integrity was assessed by standard denaturing agarose gel electrophoresis. The sample preparation and microarray hybridization were performed based on the NimbleGenâs standard protocols.

miRNA expression profiling of NKTCL (Natural Killer/T-Cell Lymphoma) samples

Project description:We performed a comprehensive genome-wide miRNA expression profiling (MEP) of extranodal nasal-type Natural Killer/T-cell lymphoma (NKTL) using formalin fixed paraffin-embedded tissue (FFPE) (n=30) and NK cell lines (n=6) in comparison with normal NK cells, with the objective of understanding the pathogenetic role of miRNA deregulation in NKTL. Total RNA, including miRNA, were extracted using Ambion Recoverall Kit and profiled using Agilent human miRNA V2.

Next-generation sequencing identifies the natural killer cell microRNA transcriptome

Project description:Natural killer (NK) cells are innate lymphocytes important for early host defense against infectious pathogens and surveillance against malignant transformation. Resting murine NK cells regulate the translation of effector molecule mRNAs (e.g. granzyme B, GzmB) through unclear molecular mechanisms. MicroRNAs (miRNAs) are small non-coding RNAs that post-transcriptionally regulate the translation of their mRNA targets, and are therefore candidates mediating this control process. While the expression and importance of miRNAs in T and B lymphocytes has been established, little is known about miRNAs in NK cells. Here, we utilized two next-generation sequencing (NGS) platforms to define the miRNA transcriptomes of resting and cytokine-activated primary murine NK cells, with confirmation by RT-qPCR and microarrays. We delineate a bioinformatics analysis pipeline that identified 302 known and 28 novel mature miRNAs from sequences obtained from NK cell small RNA libraries. These miRNAs are expressed over a broad range, exhibit isomiR complexity, and a subset is differentially expressed following cytokine-activation. Using this miRNA NGS data, miR-223 was identified as a mature miRNA present in resting NK cells with decreased expression following cytokine-activation. Further, we demonstrate that miR-223 specifically targets the 3’UTR of murine GzmB in vitro, indicating that this miRNA may contribute to control of GzmB translation in resting NK cells. Thus, the sequenced NK cell miRNA transcriptome provides a valuable framework for further elucidation of miRNA expression and function in NK cell biology. Illumina GA (SRR036363, SRR036364) and SOLiD (SRR036206, SRR036210) sequencing data have been submitted to the NCBI Sequence Read Archive (SRA). The study uses a custome made array to characterize miRNA of activated and resting murine splenic natural killer cells
