Qi Yang, Shengwen Duan, Lifeng Cheng, Xiangyuan Feng, Ke Zheng, Chao Xu & Yuande Peng
Ramie bast is a kind of multipurpose biological material. Selective bio-degradation of ramie bast compounds is an important step to partial utilization of complex polysaccharides. Bacillus subtilis is a kind of dominant species with its ability to degrade ramie bast. In order to understand how polysaccharides were catalyzed and utilized in the metabolism of the bacteria, the proteome of B. subtilis strain 168 was analyzed in the presence of ramie bast as sole carbon source,...

Aucubin slows the development of osteoporosis by inhibiting osteoclast differentiation via the nuclear factor erythroid 2-related factor 2-mediated antioxidation pathway

Yongfeng Zhang, Xin Liu, Yangyang Li, Minkai Song, Yutong Li, Anhui Yang, Yaqin Zhang, Di Wang & Min Hu
Osteoporosis (OP) is a metabolic disease. We have previously demonstrated that aucubin (AU) has anti-OP effects that are due to its promotion of the formation of osteoblasts. To investigate the mechanisms of anti-OP effects of AU. C57BL/6 mice were randomly divided into control group, 30 mg/kg Dex-induced OP group (OP model group, 15 μg/kg oestradiol-treated positive control group, 5 or 45 mg/kg AU-treated group), and 45 mg/kg AU-alone-treated group. The administration lasted for 7 weeks....

β-galactosidase GALA from Bacillus circulans with high transgalactosylation activity

Yaru Yan, Weishi Guan, Xiaoyi Li, Kaier Gao, Xinxin Xu, Bo Liu, Wei Zhang & Yuhong Zhang
β-galactosidase catalyzes lactose hydrolysis and transfers reactions to produce prebiotics such as galacto-oligosaccharides (GOS) with potential applications in the food industry and pharmaceuticals. However, there is still a need for improved transgalactosylation activity of β-galactosidases and reaction conditions of GOS production in order to maximize GOS output and reduce production costs. In this study, a β-galactosidase gene, galA, from Bacillus circulans was expressed in Pichia pastoris, which not only hydrolyzed lactose but also had strong...

Multiple Imputation Inference with Integer-Valued Point Estimates

Bo Liu & Jerome P. Reiter
We consider settings where an analyst of multiply imputed data desires an integer-valued point estimate and an associated interval estimate, for example, a count of the number of individuals with certain characteristics in a population. Even when the point estimate in each completed dataset is an integer, the multiple imputation point estimator, that is, the average of these completed-data estimators, is not guaranteed to be an integer. One natural approach is to round the standard...

However, the role of LSECs in liver regeneration in hypoxic environments and their specific molecular mechanism is unknown. Therefore, this study aimed to explore the miRNA–mRNA network that regulates the proliferation of LSECs during hypoxia. In this study, first, we found that the proliferation ability of primary LSECs treated with hypoxia was enhanced compared...

Data integration and evolutionary analysis of long non-coding RNAs in 25 flowering plants

Shiye Sang, Wen Chen, Di Zhang, Xuan Zhang, Wenjing Yang & Changning Liu
Abstract Background Long non-coding RNAs (lncRNAs) play vital roles in many important biological processes in plants. Currently, a large fraction of plant lncRNA studies center at lncRNA identification and functional analysis. Only a few plant lncRNA studies focus on understanding their evolutionary history, which is crucial for an in-depth understanding of lncRNAs. Therefore, the integration of large volumes of plant lncRNA data is required to deeply investigate the evolution of lncRNAs. Results We present a...

Yanan Han, Galina Yurevna Zheleznyakova, Yanara Marincevic-Zuniga, Majid Pahlevan Kakhki, Amanda Raine, Maria Needhamsen & Maja Jagodic
DNA methylation is the most studied epigenetic mark involved in regulation of gene expression. For low input samples, a limited number of methods for quantifying DNA methylation genome-wide has been evaluated. Here, we compared a series of input DNA amounts (1-10ng) from two methylome library preparation protocols, enzymatic methyl-seq (EM-seq) and post-bisulfite adaptor tagging (PBAT) adapted from single-cell PBAT. EM-seq takes advantage of enzymatic activity while PBAT relies on conventional bisulfite conversion for detection of...

Bowen Li, Qian Ren, Jizu Ling, Zhongbin Tao, Xuemei Yang & Yuning Li
The association of neutrophil-to-lymphocyte ratio (NLR) and mean platelet volume (MPV) with the severe gastrointestinal (GI) involvement in pediatric Henoch–Schonlein Purpura (HSP) has been reported in many studies. However, the conclusions from the previous studies were controversial. Therefore, for the first time, we performed a meta-analysis to systematically evaluate the relationship of NLR and MPV to the severe GI involvements. We retrieved PubMed, EMBASE, Web of Science, and Chinese National Knowledge Infrastructure (CNKI) (up to...

Zhongyan Zhao, Chanji Wu, Xiangying He, Eryi Zhao, Shijun Hu, Yeguang Han, Ting Wang, Yanquan Chen, Tao Liu & Shixiong Huang
Stroke is a main cause of disability and death worldwide, and ischemic stroke accounts for most stroke cases. Recently, microRNAs (miRNAs) have been verified to play critical roles in the development of stroke. Herein, we explored effects of miR-152-3p on vascular endothelial cell functions under hypoxia. Human umbilical vein endothelial cells (HUVECs) were treated with hypoxia to mimic cell injury in vitro. Reverse transcription quantitative polymerase chain reaction revealed that miR-152-3p exhibited high expression in...

Long non-coding RNA RP11-283G6.5 confines breast cancer development through modulating miR-188-3p/TMED3/Wnt/β-catenin signalling

Jing Pei, Shengquan Zhang, Xiaowei Yang, Chunguang Han, Yubo Pan, Jun Li, Zhaorui Wang, Chenyu Sun & Jing Zhang
The contributions of long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) to breast cancer are critical areas of investigation. In this study, we identified a novel lncRNA RP11-283G6.5 which was lowly expressed in breast cancer and whose low expression was correlated with poor overall survival and disease-free survival of breast cancer patients. Functional experiments revealed that ectopic expression of RP11-283G6.5 confined breast cancer cellular growth, migration, and invasion, and promoted cellular apoptosis. Conversely, RP11-283G6.5 silencing facilitated...

Cun Zhang, Yongwei Li, Changlong Yin, Jie Zheng & Guozhi Liu
Peucedanol is a major extract of Peucedanum japonicum Thunb. (Apiaceae) roots, which is a commonly used herb in paediatrics. Its interaction with cytochrome P450 enzymes (CYP450s) would lead to adverse effects or even failure of therapy. The interaction between peucedanol and CYP450s was investigated. Peucedanol (0, 2.5, 5, 10, 25, 50, and 100 μM) was incubated with eight human liver CYP isoforms (CYP1A2, 2A6, 3A4, 2C8, 2C9, 2C19, 2D6, and 2E1), in pooled human liver...
