Total and GC B cells with or without miR-146a

Project description:To examine the impact of miR-146a on GC B cell development, transcriptomic profilings of total B cells isolated from unimmunized mice with B cell-specific deletion of miR-146a (B-KO) or GC B cells isolated from B-KO mice upon sheep red blood cell (SRBC) immunization were done.

miR-146a Pulldown-sequencing data

Project description:Human CD4+ Total memory cells (CD4+CD25-CD45RA-CCR7+/-) were activated with anti-CD3/anti-CD28 antibodies and transfected with biotinylated miR-146a mimic or biotinylated mimic negative control by Exiqon. After 24h cells were lysed and miRNA:mRNA complexes pulled-down with streptavidin agarose O/N at 4°C. RNA was then purified using TRI-reagent and RNA zymospin columns. Four independent donors were used for this experiment. Total RNA was sequenced in 2 lanes, paired ends. This experiment is assessing direct targets bound by miR-146a in human T cells.

miR-146a target identification in gastric cancer

Project description:We have found expression of miR-146a up-regulated in gastric cancer. To identify new targets of miR-146a we profiled the transcriptome after miR-146a over-expression in the human gastric cancer cell line SNU638. SNU638 cells were transfected in triplicates with 50 nM miR-146a or control (siGlo) using Lipofectamine 2000. Total RNA was harvested 24 h after transfection using Trizol reagent. There are a total of six arrays included in this experiment, including three biological replicates of mRNA expression after miR-146a over-expression and three controls in SNU638 cells.

Mir-146a wild-type 3ʹ sequence identity is dispensable for proper innate immune function in vivo

Project description:A long-prevailing model has held that the “seed” region (nucleotides 2-8) of a microRNA is typically sufficient to mediate target recognition and repression. However, numerous recent studies, both within the context of defining miRNA/target pairs by direct physical association and by directly assessing this model in vivo in C. elegans have brought this model into question. To test the importance of miRNA 3' pairing in vivo, in a mammalian system, we engineered a mutant murine mir-146a allele in which the 5' half of the mature microRNA retains the sequence of the wild-type mir-146a but the 3ʹ half has been altered to be anti-complementary to the wild-type miR-146a sequence. Mice homozygous or hemizygous for this mutant allele are phenotypically indistinguishable from wild-type controls and do not recapitulate any of the immunopathology previously described for mir-146a-null mice. Our results strongly support the conclusion that 3ʹ pairing is dispensable in the context of the function of a key mammalian microRNA.

miR-146a regulates many lncRNAs in RAS induced senescence [Anti-146a]

Project description:miR-146a is a known anti-inflammatory miRNA. Intringuigly, it is overexpressed in RAS-induced senescent cells which is accompanied with a rich pro-inflammatoy secretpry phenotype. We aim to study possible sponges for miR-146a.

miR-146a promotes the initiation and progression of melanoma by activating Notch signaling

Project description:Oncogenic mutations in BRAF and NRAS occur in 70% of melanomas. Here we identify a microRNA, miR-146a, that is highly upregulated by oncogenic BRAF and NRAS. Expression of miR-146a increases the ability of human melanoma cells to proliferate in culture and form tumors in mice, whereas knockdown of miR-146a has the opposite effects. We show these oncogenic activities are due to miR-146a targeting the NUMB mRNA, a repressor of Notch signaling. Previous studies have shown that pre-miR-146a contains a single nucleotide polymorphism (C>G rs2910164). We find that the ability of pre-miR-146a/G to activate Notch signaling and promote oncogenesis is substantially higher than that of pre-miR-146a/C. Analysis of melanoma cell lines and matched patient samples indicates that during melanoma progression pre-miR-146a/G is enriched relative to pre-miR-146a/C, resulting from a C-to-G somatic mutation in pre-miR-146a/C. Collectively, our results reveal a central role for miR-146a in the initiation and progression of melanoma. SKMEL28 melanoma cell line stably expressing either an empty vector or pre-miR146a with either C or G SNP (SKMEL28-FG12, SKMEL28-miR-146a/C and SKMEL28-miR-146a/G) were used to prepare total RNA. Microarray analysis was performed by using biological replicates for each stable cell lines for a total of 6 samples.
