Psoriasis is a common and chronic inflammatory skin disease that is complicated by gene-environment interactions. Although genomic, transcriptomic, and proteomic analyses have been performed to investigate the pathogenesis of psoriasis, the role of metabolites in psoriasis, particularly of lipids, remains unclear. Lipids not only comprise the bulk of the cellular membrane bilayers but also regulate a variety of biological processes such as cell proliferation, apoptosis, immunity, angiogenesis, and inflammation...

Nowadays, the regular recommended dose of decitabine for the treatment of myelodysplastic syndrome (MDS) is 20 mg/m2/day for 5 consecutive days with a relatively high incidence of treatment-related morbidities and costs. In this study, a retrospective and multicenter analysis was performed to explore the very-low-dose decitabine schedule for the treatment of patients with IPSS intermediate- or high-risk MDS. A total of 31 newly diagnosed MDS cases from 14 hospitals in Beijing received decitabine monotherapy (decitabine 6 mg/m2/day intravenously for 7 consecutive days, repeated every 4 weeks)...

Human LCN6, a lipocalin protein, exhibits predominant expression in epididymis and location on the sperm surface. However, the biological function of LCN6 in vivo remains unknown. Herein, we found that unlike human LCN6, mouse Lcn6 gene encoded two transcript variants that were both up regulated by androgen. Subsequently, we generated a conditional knockout mouse model to disrupt Lcn6 in the adult and investigate its function. In this model, spermatogenesis was normal and Lcn6 deficiency did not affect the natural birth rate of male mice or in vitro fertilization ability of their cauda epididymal sperm...

Increasing evidence suggests that abnormal synaptic function leads to neuronal developmental disorders and is an important component of the etiology of autism spectrum disorder (ASD). Neurexins are presynaptic cell-adhesion molecules that affect the function of synapses and mediate the conduction of nerve signals. Thus, neurexins are attractive candidate genes for autism. Since gene families have greater power to reveal genetic association than single genes, we designed this case-control study to investigate six genetic variants in three neurexin genes (NRXN1, NRXN2, and NRXN3) in a Chinese population including 529 ASD patients and 1,923 healthy controls...

Advances in microfluidic emulsification have enabled the generation of exquisite multiple-core droplets, which are promising structures to accommodate microreactions. An essential requirement for conducting reactions is the sequential coalescence of the multiple cores encapsulated within these droplets, therefore, mixing the reagents together in a controlled sequence. Here, a microfluidic approach is reported for the conduction of two-step microreactions by electrically fusing three cores inside double-emulsion droplets...

Realization of the hydrogen economy relies on effective hydrogen production, storage, and utilization. The slow kinetics of hydrogen evolution and oxidation reaction (HER/HOR) in alkaline media limits many practical applications involving hydrogen generation and utilization, and how to overcome this fundamental limitation remains debatable. Here we present a kinetic study of the HOR on representative catalytic systems in alkaline media. Electrochemical measurements show that the HOR rate of Pt-Ru/C and Ru/C systems is decoupled to their hydrogen binding energy (HBE), challenging the current prevailing HBE mechanism...

Alcoholic liver disease (ALD) is a consequence of heavy and prolonged alcohol consumptions. We previously demonstrated a hepatic gamma-aminobutyric acid (GABA) signaling system that protects the liver from toxic injury. The present study was designed to investigate the role of the hepatic GABA signaling system in the process of acute ethanol exposure-induced liver injury. Our results showed that the expression of GABA synthesizing enzyme glutamic acid decarboxylase and type A GABA receptor (GABAA R) subunits was upregulated in ethanol-treated mice compared with saline-treated controls...

Barnyardgrass (Echinochloa crus-galli) is a pernicious weed in agricultural fields worldwide. The molecular mechanisms underlying its success in the absence of human intervention are presently unknown. Here we report a draft genome sequence of the hexaploid species E. crus-galli, i.e., a 1.27 Gb assembly representing 90.7% of the predicted genome size. An extremely large repertoire of genes encoding cytochrome P450 monooxygenases and glutathione S-transferases associated with detoxification are found. Two gene clusters involved in the biosynthesis of an allelochemical 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA) and a phytoalexin momilactone A are found in the E...

E3 ligases are a class of enzymes that can transfer ubiquitin to substrates for their degradation, which are of importance in cellular homeostasis. Since many oncogenic or tumor-suppressive proteins are reported to be regulated by the ubiquitin-proteasome system (UPS), E3 ligases, which function as substrate interacting modules, have been attracting more and more attention as promising anticancer drug targets due to their pivotal role in conferring substrate specificity. Generally, based on their molecular structure and functional mechanism, E3 ligases can be divided into three major types: homologous to E6-associated protein C-terminus (HECT), really interesting new gene (RING), and RING-in-between-RING (RBR) E3 ligases...
