PMID: 39515294
In mammalian cells, primary miRNAs are cleaved at their hairpin structures by the Microprocessor complex, whose core is composed of DROSHA and DGCR8. Here, we show that 5' flanking regions,...

. 2022 Mar;
82(9):1691-1707.e8.
PMID: 35349793
Transposable elements (TEs) are widespread genetic parasites known to be kept under tight transcriptional control. Here, we describe a functional connection between the mouse-orthologous "nuclear exosome targeting" (NEXT) and "human...

RNA Biol
. 2021 Sep;
18(sup1):537-547.
PMID: 34470577
Many long noncoding RNAs (lncRNAs) are localized in the nucleus and play important roles in various biological processes, including cell proliferation, differentiation and antiviral response. Yet, it remains unclear how...

Yamada T, Imamachi N, Imamura K, Taniue K, Kawamura T, Suzuki Y, et al.
Cell Rep
. 2020 May;
31(5):107542.
PMID: 32375027
RNA-binding proteins (RBPs) play a pivotal role in gene expression by modulating the stability of transcripts. However, the identification of degradation target mRNAs of RBPs remains difficult. By the combined...

Imamura K, Takaya A, Ishida Y, Fukuoka Y, Taya T, Nakaki R, et al.
EMBO J
. 2018 Jun;
37(13).
PMID: 29880601
Cytoplasmic mRNA degradation controls gene expression to help eliminate pathogens during infection. However, it has remained unclear whether such regulation also extends to nuclear RNA decay. Here, we show that...

Methods Mol Biol
. 2017 Dec;
1720:1-13.
PMID: 29236247
Analysis of RNA stability at genome-wide level is an advanced method in RNA biology that examines the half-life of each transcript. In particular, a pulse-labeling method using uridine analogs enables...

11(5):238-245.
PMID: 29021503
We screened innate immunostimulant-producing bacteria using a silkworm muscle contraction assay, and isolated Rhizobium sp. strain M2 from soil. We purified the innate immunostimulant from strain M2, and characterized the...

PMID: 25879614
Background: Histone epigenome data determined by chromatin immunoprecipitation sequencing (ChIP-seq) is used in identifying transcript regions and estimating expression levels. However, this estimation does not always correlate with eventual RNA...

PMID: 25555590
Genome-wide analysis for determining RNA turnover is an advanced method in RNA biology that examines the specific half-life of nuclear noncoding RNA (ncRNA). In particular, a pulse-labeling method using uridine...
