Jinpeng Li, Qingying Fan, Manyu Jin, Chenlong Mao, Hui Zhang, Xiaoling Zhang, Liyun Sun, Daniel Grenier, Li Yi, Xiaogai Hou & Yang Wang
Streptococcus suis (S. suis), more specifically serotype 2, is a bacterial pathogen that threatens the lives of pigs and humans. Like many other pathogens, S. suis exhibits quorum sensing (QS) system-controlled virulence factors, such as biofilm formation that complicates treatment. Therefore, impairing the QS involving LuxS/AI-2 cycle in S. suis, may be a promising alternative strategy for overcoming S. suis infections. In this study, we investigated paeoniflorin (PF), a monoterpenoid glycoside compound extracted from peony,...

Nevertheless, the role of circRNAs in cavernous nerve-damaging ED (CNI-ED) is unknown. Here, we aimed to discover novel circRNAs, probed their potential role in the CNI-ED, and construct a ceRNA network of circRNAs. Twelve male Sprague Dawley rats were randomly divided into 2 groups by us: bilateral cavernous nerve crush (BCNC) and control groups....

GlyinsRNA: a webserver for predicting glycosylation sites on small RNAs

Chunmei Cui, Xiaobin Wu & Yuan Zhou
Versatile RNA modifications play important roles in post-transcriptional regulations of gene expression, among which glycosylation modifications on small RNAs emerge as a novel clade whose characteristics need further interrogations. Here, we demonstrated that the sequence pattern around RNA glycosylation sites was not random and could be exploited for glycosylation site prediction. A machine learning predictor, GlyinsRNA, which integrated multiple RNA sequence representation encodings, was established. GlyinsRNA achieved AUROC (area under the receiver operating characteristic curve)...

Cell membrane-anchored anti-HIV single-chain antibodies and bifunctional inhibitors targeting the gp41 fusion protein: new strategies for HIV gene therapy

Yue Chen, Hongliang Jin, Xiaoran Tang, Li Li, Xiuzhu Geng, Yuanmei Zhu, Huihui Chong & Yuxian He
Emerging studies indicate that infusion of HIV-resistant cells could be an effective strategy to achieve a sterilizing or functional cure. We recently reported that glycosylphosphatidylinositol (GPI)-anchored nanobody or a fusion inhibitory peptide can render modified cells resistant to HIV-1 infection. In this study, we comprehensively characterized a panel of newly isolated HIV-1-neutralizing antibodies as GPI-anchored inhibitors. Fusion genes encoding the single-chain variable fragment (scFv) of 3BNC117, N6, PGT126, PGT128, 10E8, or 35O22 were constructed with...

Deepened snow cover mitigates soil carbon loss from intensive land use in a semi-arid temperate grassland

Ping Li, Emma Sayer, Zhou Jia, Yuntao Wu, Meifeng Deng, Xin Wang, Chao Liu, Bin Wang, Yang Wang, Yongfei Bai & Lingli Liu
Carbon (C) loss due to soil erosion is a major issue in semi-arid grasslands. The extent of soil erosion is determined by soil properties and vegetation structure, especially during the non-growing season. In many Inner Mongolian grasslands, intensive land use, such as overgrazing and mowing, has severely reduced plant cover and damaged soil structure, which has exacerbated soil C loss by erosion. At the same time, increasing winter snowfall due to climate change is stimulating...

Ziyou Tao, Chao Lu, Shuai Gao, Peng Zhang, Yuan Chen, Yuanguo Wang, Zhaoyu Yang, Kai Xiong & Yuxin Liu
Thymoma is the most common primary mass in anterior mediastinum. Although associated with low malignancy, it is often accompanied by myasthenia gravis resulting in poor prognosis. Due to the dual factors of tumor immune tolerance and autoimmune reaction, it is urgent to understand the immune status of MG with thymoma. In this study, RNA sequencing data were obtained from the TCGA and GEO cohorts to identify differentially expressed messenger RNAs and infiltrated immune cells. A...

Nitrogen addition, rather than altered precipitation, stimulates nitrous oxide emissions in an alpine steppe

Yang Yang, Yuanming Xiao, Changbin Li, Bo Wang, Yongheng Gao & Guoying Zhou
Anthropogenic-driven global change, including changes in atmospheric nitrogen (N) deposition and precipitation patterns, is dramatically altering N cycling in soil. How long-term N deposition, precipitation changes, and their interaction influence nitrous oxide (N2O) emissions remains unknown, especially in the alpine steppes of the Qinghai-Tibetan Plateau (QTP). To fill this knowledge gap, a platform of N addition (10 g m−2 yr−1) and altered precipitation (± 50% precipitation) experiments was established in an alpine steppe of the...
