#1
Lan Zhang, Yu Hu, Xiaoyu Duan, Tingting Tang, Yingbin Shen, Bin Hu, Aiping Liu, Hong Chen, Cheng Li, Yuntao Liu
Water-soluble polysaccharides were extracted from the caps and stipes of thirteen boletus mushrooms representing five different species collected in Southwest China. Investigations of their structures and antioxidant activities allowed an evaluation of structure-function relationships. The polysaccharides were composed mainly of the monosaccharides arabinose, xylose, mannose, glucose and galactose. Most samples displayed a broad molecular weight range, with significant differences observed between the molecular weight ranges of the polysaccharides from the caps and the stipes...

Among approximately 14 human-pathogenic microsporidian species, Enterocytozoon bieneusi is the most common. It can inhabit the small intestines, causing chronic diarrhea and wasting syndrome. Until now, determining prevalence and the corresponding genotypes of E. bieneusi in humans have been performed only in a few provinces of China. Herein, 93 fecal specimens were collected from diarrheic children in Chongqing. By PCR and sequencing of the internal transcribed spacer (ITS) region of the E. bieneusi rDNA sequence, we found 11 (11...

The main challenge of anticancer drugs is poor tumor targeting. Now cellular carriers are widely investigated to deliver anticancer agents. As an ideal cellular candidate, human umbilical cord derived mesenchymal stem cells (hUC-MSCs) possess inherent tropism potential to tumor. Here, we constructed hUC-MSCs carrying transferrin-inspired-nanoparticles that contain doxorubicin(hUC-MSCs-Tf-inspired-NPs) to achieve enhanced anti-tumor efficacy and made an evaluation. Results represented that hUC-MSCs-Tf-inspired-NPs not only exhibit the controlled-release property of Tf-inspired-NPs, but also integrate tumor tropism and penetrative abilities of MSCs...

An efficient base-promoted C(sp3)-H bond functionalization strategy for the synthesis of multi-substituted chromans from the formal [3+3] cycloaddition of benzo[c]oxepines and electron-rich phenols has been developed. The corresponding 4H-chromenes can be easily obtained in excellent yields by simple filtration from chromans. Preliminary mechanistic studies indicate that the C-O bond cleavage is the key step for the C(sp3)-H bond functionalization and this reaction could have occurred through a tandem C-O bond cleavage/ Michael addition/ annulation reactions...

SCN5A encodes the voltage-gated Na+ channel NaV1.5 that is responsible for depolarization of the cardiac action potential and rapid intercellular conduction. Mutations disrupting the SCN5A coding sequence cause inherited arrhythmias and cardiomyopathy, and single-nucleotide polymorphisms (SNPs) linked to SCN5A splicing, localization, and function associate with heart failure-related sudden cardiac death. However, the clinical relevance of SNPs that modulate SCN5A expression levels remains understudied. We recently generated a transcriptome-wide map of microRNA (miR) binding sites in human heart, evaluated their overlap with common SNPs, and identified a synonymous SNP (rs1805126) adjacent to a miR-24 site within the SCN5A coding sequence...

The compensatory proliferation of insulin-producing β cells is critical to maintaining glucose homeostasis at the early stage of type 2 diabetes. Failure of β cells to proliferate results in hyperglycemia and insulin dependence in patients. To understand the effect of the interplay between β cell compensation and lipid metabolism upon obesity and peripheral insulin resistance, we eliminated LDL receptor-related protein 1 (LRP1), a pleiotropic mediator of cholesterol, insulin, energy metabolism, and other cellular processes, in β cells...

Eradication of HIV-1 (HIV) is hindered by stable viral reservoirs. Viral latency is epigenetically regulated. While the effects of histone acetylation and methylation at the HIV long-terminal repeat (LTR) have been described, our knowledge of the proviral epigenetic landscape is incomplete. We report that a previously unrecognized epigenetic modification of the HIV LTR, histone crotonylation, is a regulator of HIV latency. Reactivation of latent HIV was achieved following the induction of histone crotonylation through increased expression of the crotonyl-CoA-producing enzyme acyl-CoA synthetase short-chain family member 2 (ACSS2)...

We develop a new fluorescence method for the sensitive detection of alkaline phosphatase (ALP) based on dephosphorylation-initiated transcription reaction-mediated dual signal amplification. This research demonstrates for the first time a significant improvement in ALP assay performance by using a nucleic acid amplification strategy, which enables sensitive detection of ALP activity in vitro and in cell extracts. Importantly, this method can be further applied for kinetic analysis and ALP inhibition assay.

Background: Eosinophil-lineage committed progenitor cells (EoP) migrate from the bone marrow and differentiate locally to provide an ongoing source of mature eosinophils in asthmatic inflammatory responses in the airways. Sputum levels of EoP are increased in asthmatics compared to normal controls suggesting an exaggerated eosinophilopoietic environment in the airways. Understanding what factors promote EoP traffic to the airways is important to understand the diathesis of asthma pathology...

Biaryl amides as new RORγt modulators were discovered. The crystal structure of biaryl amide agonist 6 in complex with RORγt ligand binding domain (LBD) was resolved, and both "short" and "long" inverse agonists were obtained by removing from 6 or adding to 6 a proper structural moiety. While "short" inverse agonist ( 8 ) recruits a corepressor peptide and dispels a coactivator peptide, "long" inverse agonist ( 9 ) dispels both. The two types of inverse agonists can be utilized as potential tools to study mechanisms of Th17 transcriptional network inhibition and related disease biology...
