ProteomicsCBB staining showed beneficial effects on proteomic analysis employing PAGE separation followed with whole-gel slicing, in-gel digestion and quantitative LC-MS/MS
Proteomic analysis by combining PAGE separation, gel slicing and slice-by-slice LC-MS/MS has been frequently reported in recent years. Since the MS analysis would provide identities and quantities of the proteins along the whole lane, visualization by dye staining could be skipped to save time and ...

ProteomicsA new method for differential proteomic analysis utilizing native MS-electropherograms: a comparison between plasma and serum proteins by combining native PAGE, whole-gel slicing and quantitative LC-MS/MS
MS identification has long been used for PAGE-separated protein bands, but global and systematic quantitation utilizing MS after PAGE has remained rare and not been reported for native PAGE. Here we reported on a new method combining native PAGE, whole-gel slicing and quantitative LC-MS/MS aiming c...

Proteomics1DE-MS profiling of rat cerebral cortex proteins of focal cerebral ischemia-reperfusion injury by combining SDS-PAGE, gel slicing, quantitative LC-MS/MS and profile reconstruction
A rat model of focal cerebral ischemia-reperfusion (I/R) injury was established by 2 hour-middle cerebral artery occlusion (MCAO) followed with 1, 7 and 14 days of reperfusion. Validation of the model was done by the measurement on cerebral blood flow, infarct volume, histological damage and neurol...

TranscriptomicsPIWI slicing and EXD1 drive biogenesis of nuclear piRNAs from cytosolic targets of the mouse piRNA pathway
PIWI-interacting RNAs (piRNAs) guide PIWI proteins to suppress transposable elements in animal gonads. Here we demonstrate that in the mouse embryonic male germline, endonucleolytic cleavage (slicing) of a transcript by cytosolic MILI acts as a trigger to initiate its further 5??3? processing into n...

ProteomicsProteomic analysis of focal cerebral ischemia/reperfusion injury in rats
Stroke is a leading cause of mortality and long-term disability and ischemic stroke accounts for 87% of all strokes. Though timely recanalization of the occluded vessel is essential in the treatment of ischemic stroke, it is well known to cause ischemia-reperfusion (I/R) injury which result in neuro...

TranscriptomicsRNA clamping by Vasa assembles a piRNA Amplifier complex on transposon transcripts
Germline-specific Piwi-interacting RNAs (piRNAs) protect the genome against selfish genetic elements and are essential for fertility in animals. piRNAs targeting active transposons are amplified by a feed-forward loop known as the Ping-pong cycle, which links endonucleolytic slicing of target RNA...

TranscriptomicsFunctional analysis of Arabidopsis ARGONAUTE1 using a slicer-defective mutant: Small RNA immunoprecipitation
The Arabidopsis ARGONAUTE (AGO) protein AGO1 associates with microRNA (miRNA) and specific classes of short-interfering RNA (siRNA). AGO1-small RNA complexes recognize target RNA transcripts through base-pairing interactions and inhibit translation of target RNAs through endonucleolytic cleavage (sl...

TranscriptomicsFunction, targets and evolution of Caenorhabditis elegans piRNAs (small RNA-Seq)
piRNAs are required to maintain germline integrity and fertility but their mechanism of action is poorly understood. Here we demonstrate that C. elegans piRNAs silence transcripts in trans through imperfectly complementary sites. We find that target silencing is independent of Piwi endonuclease acti...

TranscriptomicsThe structure of human Argonaute-2 in complex with miR-20a
Argonaute proteins lie at the heart of the RNA-Induced Silencing Complex (RISC), wherein they use small RNA guides to recognize targets. Some Argonaute proteins can directly cleave their targets, whereas others recruit co-factors to repress independently of “slicing.” Prior studies established the a...
