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...

MetabolomicsBased on the Metabolomic Approach the Energy Metabolism Responses of Oriental River Prawn Macrobrachium nipponense Hepatopancreas to Acute Hypoxia and Reoxygenation
Hypoxia represents a major physiological challenge for prawns and is a problem in aquaculture. Therefore, an understanding of the metabolic response mechanism of economically important prawn species to hypoxia and re-oxygenation is essential. However, little is known about the intrinsic mechanisms b...

ProteomicsMelatonin confers saline-alkali tolerance by relieving nitrosative damage and S-nitrosylation of plasma membrane H+-ATPase 2 in tomato
Soil salination and alkalization are global problems impairing plant survival by disrupting REDOX homeostasis. Whether melatonin regulates REDOX homeostasis at nitrosative level, and thus affects plant saline-alkali tolerance remains unknown. In saline-alkali stress, excess nitric oxide (NO) causes ...

TranscriptomicsTime course of oxidative stress responses in yeast, caused by Menadione or hydrogen peroxide
Oxidative stress caused by Menadione or Hydrogen peroxide in synchronized Saccharomyces cerevisiae cultures. Alpha factor synchronized cultures (0.2-0.4 OD), treated at the beginning of S phase (25 min after release from G1 arrest) with either 2 mM Menadione (MD) or 0.24 mM Hydrogen peroxide (HP), s...

ProteomicsDNA damage-induced alternative splicing of p53
Samples were reduced in loading buffer and separated by SDS-PAGE for 3-4 min followed by in-gel digestion with trypsin. Digests were analyzed by LC-MS/MS using a Waters nanoACQUITY interfaced to a Thermo Fusion Lumos MS. The LC separation 90 min gradient of 5-30% MeCN in a trapping configurations w...

TranscriptomicsThe transcriptomic changes affected by BDF2 and SIR2 under salt stress
The strain bdf1M-bM-^HM-^Fbdf2M-bM-^HM-^F[BDF2 L][SIR2 H] improved salt resistance of bdf1M-bM-^HM-^F. To gain further insight into the mechanism of BDF1 in suppressing bdf1M-bM-^HM-^F salt sensitivity, DNA microarray analysis was performed to determine the reason for the salt sensitivity of bdf1M-b...

TranscriptomicsClassification of three temporal kinetic transcripts of SGIV
Singapore grouper iridovirus (SGIV) is the major agent that causes severe iridovirus diseases in grouper maricluture. Based on the genomic information, a DNA microarray, containing probes corresponding to 162 putative SGIV open reading frames (ORFs) was constucted. The viral microarrays wereused to ...

MetabolomicsMitochondrial Transplantation of Brown Adipocytes Interferes with the Metabolism of Tumor Stem Cells and Inhibits the Recurrence of Brain Glioma after Operation

Glioblastoma multiforme (GBM) is highly aggressive, with treatment resistance and recurrence driven by metabolically plastic glioma stem cells (GSCs). Inspired by brown adipose tissue (BAT) thermogenesis, researchers transplanted BAT-derived mitochondria (BA-Mito) into GSCs, reducing stemness mar...

MetabolomicsMetabolomic profiling of Campylobacter jejuni with resistance gene ermB by ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry and tandem quadrupole mass spectrometry
The metabolome changes of Campylobacter jejuni with resistant gene ermB remain unclear. Here, we described an untargeted metabolomic workflow based on ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry to investigate the metabolites perturbations mediated by erm...

GenomicsChIP-Seq analysis of ER binding sites in MCF7 breast cancer cells
Estrogen Receptor (ER) is a hormonal transcription factor that plays important roles in breast cancer. It functions primarily through binding to the regulatory regions of target genes containing the consensus ERE motifs. In order to identify ER target genes and re-define the ERE motifs we performed...
