The Chinese herbal prescription JieZe-1 (JZ-1) is effective against HSV-2 (Herpes simplex virus type 2) infection. However, its mechanism remains unclear. To explore the mechanism of JZ-1 in protecting against HSV-2 infection. Using the methods of network pharmacology, the hub components and targets were screened and functionally enriched. We established a genital herpes (GH) mouse model and observe the disease characteristics. Then, the GH mice in different groups (10 per/group) were treated with 20 μL...

Functional redundancy changes along a drought stress gradient for the shift of selection effect to complementarity effect in experimental plant communities

Song Gao, Xiaoyan Wang, Tong Chen, Qiaodi Yan, Mengchun Shen, Jiang Wang & Feihai Yu
Species interactions alter with environmental change, which influences the relationship between biodiversity and ecosystem functioning (BEF). How BEF relationships change with environments requires knowledge of the changes of functional attributes in individual species in response to environmental change. Here, we assembled experimental plant communities with different species richness (1, 2, 4, 8, and 16) and exposed them to a drought stress gradient (control, moderate and intensive drought stress). Functional redundancy decreased with increasing drought stress...

Difficulties translating antisense-mediated activation of Frataxin expression from cell culture to mice

Audrius Kilikevicius, Jun Wang, Xiulong Shen, Frank Rigo, Thahza P. Prakash, Marek Napierala & David R. Corey
Friedreich’s ataxia (FA) is an inherited neurodegenerative disorder caused by decreased expression of frataxin (FXN) protein. Previous studies have shown that antisense oligonucleotides (ASOs) and single-stranded silencing RNAs can be used to increase expression of frataxin in cultured patient-derived cells. In this study, we investigate the potential for oligonucleotides to increase frataxin expression in a mouse model for FA. After confirming successful in vivo delivery of oligonucleotides using a benchmark gapmer targeting the nuclear noncoding...

The Effect of the Acidic Gas Pollutant on Wool Keratin Fiber Structure

Zhe Jiang, Rubing Bai, Jinfang Zhang, Ende Li, Yifan Cui, Ning Zhang, Nan Zhang & Qiang Wang
Increase in air pollution caused by acidic gases, such as nitrogen dioxide, call for the need to study potential effects on the structure of textile materials. Wool is a natural protein fiber which is easily damaged due to rich reaction positions and cross-linked bonds in the fiber. This study reports, for the first time, effect of nitrogen dioxide, as a model acid gas pollutant, on the structure of wool. On the macro level, wool fabric...

Hui Liu, Huihua Zhang, Deheng Shi & Zunlue Zhu
The potential energy curves of 103 Ω states generated from the 39 Λ–S states of PN have been calculated using the internally contracted multireference configuration interaction method with the Davidson modification. Core-valence correlation and scalar relativistic corrections, as well as the basis-set extrapolation to the complete basis set limit are considered. The spin–orbit coupling is computed using the state interaction approach with the Breit-Pauli Hamiltonian. The spectroscopic parameters and molecular constants of bound and quasibound...

Kenaf (Hibiscus cannabinus L.) is an industrial fiber crop with significant heterosis and tolerance to abiotic stresses. However, the mechanism underlying heterosis in kenaf under drought conditions is completely unknown. In this study, F1 hybrids were remarkably tolerant to drought stress. Through methylation-sensitive amplification polymorphism (MSAP) analysis, we highlighted that total DNA methylation level under drought decreased by 11.2% in F1 and increased by 29.7% and 13.1% in parents CP079 and CP071, respectively. Unlike parents,...

Autophagy loss impedes cancer-associated fibroblast activation via downregulating proline biosynthesis

Jingru Bai, Tong Liu, Bo Tu, Meng Yuan, Zhaoqi Shu, Minghe Fan, Sihan Huo, Yuyao Guo, Lina Wang, Hua Wang & Ying Zhao
Cancer-associated fibroblasts (CAFs) are considered one of the most critical stromal cells that interact with pancreatic ductal adenocarcinoma (PDAC) and promote tumor growth, metastasis, and treatment resistance. Previous studies illustrated macroautophagy/autophagy contributes to CAF activation during tumor progression. Here in our study, we found that autophagy deficiency in CAFs impedes CAF activation by inhibiting proline biosynthesis and collagen production. Furthermore, we uncovered that autophagy promotes proline biosynthesis through mitophagy-mediated regulation of NADK2 (NAD kinase 2,...

Bias reduction by transformed flat-top Fourier series estimator of density on compact support

Liang Wang & Dimitris N. Politis
The problem of nonparametric estimation of a univariate density with rth continuous derivative on compact support is addressed (r≥2). If the density function has compact support and is non-zero at either boundary, regular kernel estimator will be completely biased at such boundary. Although several correction methods were proposed to improve the bias at the boundary to h2 in the last decades, this paper initiates a way to further improve bias to higher order (hr) for...

DAR-PCR: a new tool for efficient retrieval of unknown flanking genomic DNA

Tianyi Sun, Mengya Jia, Lingqin Wang, Zhaoqin Li, Zhiyu Lin, Cheng Wei, Jinfeng Pei & Haixing Li
Abstract Various PCR-based genome-walking methods have been developed to acquire unknown flanking DNA sequences. However, the specificity and efficacy levels, and the operational processes, of the available methods are unsatisfactory. This work proposes a novel walking approach, termed differential annealing-mediated racket PCR (DAR-PCR). The key to DAR-PCR is the use of primer-mediated intra-strand annealing (ISA). An ISA primer consists of a 5’ root homologous to the known sequence and a heterologous 3’ bud. In the...

Nan Zhang, Hong‑Ping Zhu, Wei Huang, Xiang Wen, Xin Xie, Xian Jiang, Cheng Peng, Bo Han & Gu He
Abstract Peripheral myelin protein 22 (PMP22) and epithelial membrane proteins (EMP-1, -2, and -3) belong to a small hydrophobic membrane protein subfamily, with four transmembrane structures. PMP22 and EMPs are widely expressed in various tissues and play important roles in cell growth, differentiation, programmed cell death, and metastasis. PMP22 presents its highest expression in the peripheral nerve and participates in normal physiological and pathological processes of the peripheral nervous system.
