MetabolomicsZika virus disrupts steroidogenesis and impairs spermatogenesis by stalling the translation of CYP17A1 mRNA

ZIKV infection is associated with testicular damage and abnormal spermatogenesis. However, the molecular mechanisms underlying these pathogenic processes remain unclear. Here, we demonstrate that ZIKV disrupts Leydig cells' ability to produce testosterone, leading to decreased sperm counts and mo...

MetabolomicsOxygen-induced pathological angiogenesis promotes intense lipid synthesis and remodeling in the retina

The retina is a notable tissue with high metabolic needs which relies on specialized vascular networks to protect the neural retina while maintaining constant supplies of oxygen, nutrients and dietary essential fatty acids. Here we analyzed the lipidome of the mouse retina under healthy and patho...

TranscriptomicsRpb4 functions mainly in mRNA synthesis by RNA polymerase II
RNA polymerase II (Pol II) is the central enzyme that carries out eukaryotic mRNA transcription and consists of a 10-subunit catalytic core and a heterodimeric subcomplex of subunits Rpb4 and Rpb7 (Rpb4/7). Rpb4/7 has been proposed to shuttle from the nucleus to the cytoplasm, and to function there ...

MetabolomicsEnhanced fatty acid synthesis by Sigma28 in stringent responses contributes to multidrug resistance and biofilm formation in Helicobacter pylori

The metabolism of bacteria is closely associated with antibiotic resistance, yet the role of metabolism in the resistance of Helicobacter pylori remains unclear. In this study, we conducted integrated analysis using transcriptomics and non-targeted metabolomics to investigate the metabolic change...

TranscriptomicsSynthesis vs. Abundance, Bradyzoite Development
Parasites grown as either tachyzoites or bradyzoites for 40 hours were pulsed with 2,4-dithiouracil (DTU) for 1 hour. Following the pulse, mRNA was extracted and either used directly in microarray experiments (Abundance Arrays) or biotinylated and purified to select DTU labeled RNAs that were then ...

TranscriptomicsDynamic transcriptome analysis reveals mRNA synthesis and decay in yeast
To obtain rates of mRNA synthesis and decay in yeast, we established dynamic transcriptome analysis (DTA). DTA combines non-perturbing metabolic RNA labeling with dynamic kinetic modeling. DTA was used to monitor the cellular response to osmotic stress in comparison to the wild type. Genomic occupa...

TranscriptomicsGenomic Run-On (GRO): determination of the nascent transcriptional rate and mRNA amount in Xrn1 mutants
Maintaining the proper mRNA levels is a key aspect in the regulation of gene expression. The balance between mRNA synthesis and decay determines these levels. Using a whole-genome analysis, we demonstrate that most yeast mRNAs are degraded by the 5'-to-3' pathway (the "decaysome"), as prop...

ProteomicsYBX3 is a versatile RNA-binding protein that controls amino acid import by regulating SLC mRNA abundance
Summary: Amino acids (AA) support protein synthesis, and thus cell growth and proliferation. Specialized transporters mediate AA exchange across membranes and their regulation is critical for AA homeostasis. Here, we report that the DNA- and RNA-binding protein YBX3 regulates the expression of AA t...
