Tetracycline (TC), a widely used veterinary antibiotic, is a pervasive emerging contaminant threatening crop production. Here, we employed integrated physiological, metabolomic, and transcriptomic analyses to decipher the response of soybean (Glycine max L.) to TC. While seed germination was unaffec...
Lung cancer (LC) is still one of the most deadly cancers in the world, but there is a lack of non-invasive biomarkers to assist diagnosis and guide treatment. Herein, untargeted serum metabolomics of 57 LC patients and 59 HC people was performed based on gas chromatography-mass spectrography (GC-...

Abstract:
Cells sense several kinds of stimu...
BACKGROUND: In addition to determining static states of gene expression (high vs. low), it is important to characterize their dynamic status. For example, genes with H3K27me3 chromatin marks are not only suppressed but also poised for activation. However, the responsiveness of genes to perturbations...
Transfer RNA (tRNA) modifications enhance the efficiency, specificity and fidelity of translation in all organisms. The anticodon modification mcm5s2U34 is required for normal growth and stress resistance in yeast; mutants lacking this modification have numerous phenotypes. Mutations in the homologo...
Mitogen-activated dual-specificity MAPK phosphatases are important negative regulators in the MAPK signalling pathways responsible for many essential processes in plants. In a screen for mutants with reduced organ size we have identified a mutation in the active site of the dual-specificity MAPK ph...
The activity of Src-family kinases (SFKs), which phosphorylate immunoreceptor tyrosine-based activation motifs (ITAMs), is a critical factor regulating myeloid-cell activation. In a previous paper (Freedman et al., 2015) we showed that the SFK LynA is uniquely susceptible to rapid ubiquitin-mediated...
Spermatogonial stem cells (SSCs) possess the capacity for spontaneous reprogramming during in vitro culture, while the underlying mechanisms remain poorly understood, especially why addition of epidermal growth factor (EGF), leukemia inhibitory factor (LIF) remarkably enhanced transition efficien...
Crosstalk and complexity within signaling pathways has limited our ability to devise rational strategies for using network biology to treat human disease. This is particularly problematic in cancer where oncogenes that drive or maintain the tumorigenic state alter the normal flow of molecular inform...
