HIF-1α promotes the keloid development through the activation of TGF-β/Smad and TLR4/MyD88/NF-κB pathways

Rui Lei, Jian Li, Feng Liu, Weihan Li, Shizhen Zhang, Yang Wang, Xi Chu & Jinghong Xu
A keloid is defined as an overgrowth of the dense fibrous tissues that form around a wound. Since they destroy the vascular network, keloid tissues often exhibit anoxic conditions. Hypoxia-inducible factor-1α (HIF-1α) is a core factor that mediates hypoxia stress responses and regulates the hypoxic cellular and biological behaviors. In this study, we found that the expression level of HIF-1α in keloid tissue was significantly higher than that in the normal skin tissue. Hypoxia-induced HIF-1α...

Comparative study of excretory–secretory proteins released by Schistosoma mansoni-resistant, susceptible and naïve Biomphalaria glabrata

Conor E. Fogarty, Min Zhao, Donald P. McManus, Mary G. Duke, Scott F. Cummins & Tianfang Wang
Abstract Background Schistosomiasis is a harmful neglected tropical disease caused by infection with Schistosoma spp., such as Schistosoma mansoni. Schistosoma must transition within a molluscan host to survive. Chemical analyses of schistosome-molluscan interactions indicate that host identification involves chemosensation, including naïve host preference. Proteomic technique advances enable sophisticated comparative analyses between infected and naïve snail host proteins. This study aimed to compare resistant, susceptible and naïve Biomphalaria glabrata snail-conditioned water (SCW) to identify potential attractants...

Landscape of RNA editing reveals new insights into the dynamic gene regulation of spermatogenesis

Xiaodan Wang, Xiaolong Wu, Zhenshuo Zhu, Hao Li, Tongtong Li, Qun Li, Peng Zhang, Leijie Li, Dongxue Che, Xia Xiao, Tong Liu, Jinlian Hua & Mingzhi Liao
Spermatogenesis is an important physiological process associated with male infertility. As a kind of post-transcriptional regulation, RNA editings (REs) change the genetic information at the mRNA level. But whether there are REs and what’s the role of REs during the process are still unclear. In this study, we integrated published RNA-Seq datasets and established a landscape of RNA REs during the development of mouse spermatogenesis. Totally, 7530 editing sites occurred in 2012 genes among all...

Sevoflurane suppresses migration and invasion of glioma cells by regulating miR-146b-5p and MMP16

Le Zhang, Jun Wang, Zhijie Fu, YanQiu Ai, Yanrong Li, Ying Wang & Yanping Wang
Glioma is the most common brain tumor with poor prognosis all over the world. Anesthetics have been demonstrated to have important impacts on cell migration and invasion in different cancers. However, the underlying mechanism that allows anesthetics-mediated progression of glioma cells remains elusive. Sevoflurane (Sev), a class of common anesthetics, was used to expose to U87-MG and U251 cells. The expressions of microRNA-146b-5p (miR-146b-5p) and matrix metallopeptidase 16 (MMP16)were measured by quantitative real-time polymerase chain...

Yanmeng Chen, Bocun Shen, Xiaochuan Zheng, Quanxin Long, Jie Xia, Yao Huang, Xuefei Cai, Deqiang Wang, Juan Chen, Ni Tang, Ailong Huang & Yuan Hu
Hepatitis B virus (HBV) is a partially double-stranded DNA virus that replicates by reverse transcription. We previously demonstrated that the host restriction factor-APOBEC3B (A3B) inhibited HBV replication which was dependent on its deaminase activity during reverse transcription. However, the host factors involved in the process of regulating the anti-HBV function of A3B are less known. In this research, to obtain a comprehensive understanding of the interaction networks of A3B, we conducted coimmunoprecipitation and mass spectrometry...

Tick-borne encephalitis virus NS4A ubiquitination antagonizes type I interferon-stimulated STAT1/2 signalling pathway

Qi Yang, Jia You, Yuan Zhou, Yun Wang, Rongjuan Pei, Xinwen Chen, Min Yang & Jizheng Chen
Tick-borne encephalitis virus (TBEV) accounts for approximately 10,000 annual cases of severe encephalitis in Europe and Asia and causes encephalitis in humans. In this study, we demonstrate TBEV appears to activate the interferon (IFN)-β dependent on RIG-I/MDA5. Both the IFN-β accumulation and the IFN stimulated genes (ISGs) transcription greatly delay. Further studies reveal that TBEV NS4A could block the phosphorylation and dimerization of STAT1/STAT2 to affect type I and II IFN-mediated STAT signalling. Additional data...
