Water transport from roots to leaves through xylem is important for plant growth and development. Defects in water transport can cause drought stress, even when there is adequate water in the soil. Here, we identified the maize (Zea mays) wilty5 (wi5) mutant, which exhibits marked dwarfing and leaf wilting throughout most of its life cycle under normal growth conditions. wi5 seedlings exhibited lower xylem conductivity and wilted more rapidly under drought, NaCl, and high temperature treatments than wild type plants. Map-based cloning revealed that WI5 encodes an active endo-1,4-β-xylanase from glycosyl dehydration family 10, which mainly functions in degrading and reorganizing cell wall xylan. RT-PCR and GUS assays revealed that WI5 is highly expressed in stems, especially in internodes undergoing secondary wall assembly. RNA-seq suggested that WI5 plays a unique role in internode growth. Immunohistochemistry and electron microscopy confirmed that wi5 is defective in xylan deposition and secondary cell wall thickening. Lignin deposition and xylan content were markedly reduced in wi5 compared to the wild type plants. Our results suggest that WI5 functions in xylem cell wall thickening through its xylanase activity and thereby regulates xylem water transport, the drought stress response, and plant growth in maize.

Hypoxia inducible factor-1α (HIF-1α) plays an important role in anti-inflammatory and cellular responses to hypoxia. Previous studies have found that B or T cell-specific HIF-1α Knock Out (KO) mice exhibit severe colonic inflammation. However, we know very little about other functions of HIF-1α in intestinal epithelial cells (IECs). In our study, HIF-1αΔIEC mice were used to study the function of HIF-1α in IECs. HIF-1α was knocked down in Caco2 cells by transfection with a small interfering (si) RNA. Immunohistochemical (IHC) staining and Western blotting were used to detect the expression of Zonula Occluden-1 (ZO1) and Occludin. The content of colon was harvested for high performance liquid chromatography analysis to examine the levels of butyrate in the gut. Our research found that HIF-1α played a protective role in Dextran sulphate sodium (DSS)-induced colitis which was partly due to its regulation of TJ protein expression. Further study revealed that HIF-1α mediated TJ proteins levels by moderating the content of butyrate. Moreover, we found that butyrate regulated TJ protein expression which is dependent on HIF-1α. These results indicated that there is a mutual regulatory mechanism between butyrate and HIF-1α and have an important contribution to the study of HIF1a and butyrate in the maintenance of barrier function of the gastrointestinal (GI) tract.

However, the molecular basis of the antidepressant mechanism of LBRD and the quality marker ingredients of LBRD remain unclear. This study aimed to investigate the quality marker ingredients of LBRD and to show the molecular mechanism of its antidepressant activities. In this study, we adopted the chronic unpredicted mild stress paradigm to construct a depression model. High-performance liquid chromatography (HPLC) was used to determine the levels of the main markers in LBRD. The underlying mechanism of LBRD was explored by measuring neurotransmitter and cytokine levels using enzyme-linked immunosorbent assay, and by quantifying differentially expressed gene (DEG) of transcriptome in the medial prefrontal cortex (mPFC) tissue through RNA sequencing. HPLC results showed that the average levels of quality marker ingredients of LBRD (ferulic acid, dioscin, verbascoside and catalpol) were 0.00079%, 0.00039%, 0.7% and 1.6% (w/w), respectively. LBRD intervention significantly attenuated the depressive phenotype compared with that in the depressed group. LBRD treatment altered the enriched DEGs in the signaling pathways of γ-aminobutyric acid (GABA) and glutamate neurotransmitter, synaptic plasticity and axon guidance, circadian rhythm and neural-immunity. GABAergic and glutamatergic synapses as well as brain-derived neurotrophic factor (BDNF)/TrkB-dependent phosphoinositide 3-kinase (PI3K)/Akt/mammalian target of rapamycin-1 (mTOR1), might be the main signaling pathways underlying the multi-target therapeutic effects of LBRD against depression. © 2020 John Wiley & Sons Ltd and International Behavioural and Neural Genetics Society.The synthesis of silacycles is highly appealing due to their important applications in organic synthesis, medicinal chemistry, and materials chemistry. However, sila-tetralins and sila-benzosuberanes are surprisingly under-represented due to a lack of general methods to access these compounds. We successfully developed a Pd-catalyzed strain-release silicon-based cross-coupling as an unprecedented ring-expansion method, which constitutes a general route for preparing diverse sila-tetralins and sila-benzosuberanes. © 2020 Wiley-VCH Verlag GmbH & Co.

CP 43 However, endoscopic submucosal dissection (ESD) can be tedious procedures and require a long and extensive training to master. Devices for endoscopic full-thickness resection (EFTR) are limited and not widely available. We report here a simpler endoscopic method to resect small SETs using a commercially available endoscopic mucosal resection (EMR) kit and enucleation technique. METHODS All patients with SETs who underwent device-assisted resection at our tertiary care hospital during April 2015 and November 2016 were enrolled in this retrospective study. All procedures were performed by a single expert endoscopist with an advanced endoscopy trainee. A mucosotomy and a limited dissection under mucosa were performed to preserve the mucosa before device-assisted nucleation of the tumor to facilitate endoscopic closure of the defect closure in all cases. RESULTS A total of 12 patients (6 male, age 38 to 70 years old) were included.
