PIWI Slicing and RNA Elements in Precursors Instruct Directional Primary piRNA Biogenesis

Cell Reports, 2015
PIWI proteins and PIWI-interacting RNAs (piRNAs) mediate repression of transposons in the animal gonads. Primary processing converts long single-stranded RNAs into ∼30-nt piRNAs, but their entry into the biogenesis pathway is unknown.

PANoptosis in the pathogenesis of myelodysplastic syndromes

Molecular Oncology, EarlyView.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

Determination of ribonuclease sequence-specificity using Pentaprobes and mass spectrometry

, 2012
The VapBC toxin-antitoxin (TA) family is the largest of nine identified TA families. The toxin, VapC, is a metal-dependent ribonuclease that is inhibited by its cognate antitoxin, VapB. Although the VapBCs are the largest TA family, little is known about

Rrp47p is an exosome-associated protein required for the 3 ' processing of stable RNAs [PDF]

, 2003
Related exosome complexes of 3'-->5' exonucleases are present in the nucleus and the cytoplasm. Purification of exosome complexes from whole-cell lysates identified a Mg2+-labile factor present in substoichiometric amounts. This protein was identified

Role of CXCL10 released from osteocytes in response to TNF-α stimulation on osteoclasts

Scientific Reports
Tumor necrosis factor-alpha (TNF-α) is a significant cytokine that regulates bone resorption under inflammatory conditions. However, its mechanism of action in osteocytes remains unclear.

ADP‐ribosylation: An emerging regulator of the epigenome

Molecular Oncology, EarlyView.
ADP‐ribosylation has emerged as a dynamic epigenetic signaling mechanism that modifies histones and chromatin‐associated proteins. Through coordinated PARylation and MARylation, it integrates with other histone modifications to regulate chromatin structure, transcription factor activity, and gene expression, influencing genome function and disease ...

Structural insights into the dynamics and function of the C-terminus of the E. coli RNA chaperone Hfq [PDF]

, 2011
The hexameric Escherichia coli RNA chaperone Hfq (Hfq(Ec)) is involved in riboregulation of target mRNAs by small trans-encoded RNAs. Hfq proteins of different bacteria comprise an evolutionarily conserved core, whereas the C-terminus is variable in ...

Profiling and characterization of a longissimus dorsi muscle microRNA dataset from an F2 Duroc × Pietrain pig resource population

Genomics Data, 2017
To elucidate the effects of microRNA (miRNA) regulation in skeletal muscle of adult pigs, miRNA expression profiling was performed with RNA extracted from longissimus dorsi (LD) muscle samples from 174 F2 pigs (~5.5 months of age) from a Duroc × Pietrain

Profiling neoadjuvant therapy response in rectal cancer using meta‐analysis of publicly available transcriptomic RNA‐seq datasets

Molecular Oncology, EarlyView.
This study integrates publicly available transcriptomic datasets to identify molecular signatures associated with response to neoadjuvant chemoradiotherapy in locally advanced rectal cancer. By analyzing a combination of multiple cohorts with bioinformatics approaches, we reveal biological pathways and immune‐related features that may improve ...

The type II poly(A)-binding protein PABP-2 is a downstream target of the "let-7" microRNA in the heterochronic pathway of "Caenorhabditis elegans" : mechanisms of microRNA-mediated gene silencing in "Caenorhabditis elegans" [PDF]

, 2012
microRNAs (miRNAs) are a large class of small, non-coding RNAs that post-transcriptionally regulate gene expression in animals, plants and protozoa. miRNAs are genomically encoded and transcribed by RNA polymerase II. Primary transcripts are sequentially
