Tumor-derived exosomal miRNA-141 promote angiogenesis and malignant progression of lung cancer by targeting growth arrest-specific homeobox gene (GAX)

Wulong Wang, Guodai Hong, Siyuan Wang, Wenbin Gao & Ping Wang
Previous researches have suggested that exosomal miRNA-141 has association with metastatic lung cancer, however, its role and regulatory mechanism require further study. In this study, exosomes were isolated from lung cancer patients and normal human serum and identified. We found that the expression of miRNA-141 was up-regulated in the lung cancer serum exosomes compared with the normal serum exosomes. When the exosomes were extracted for co-culture with HUVECs, they were absorbed and distributed around the...

Dahai Liu, Li Liu, Kui Duan, Junqiang Guo, Shipeng Li, Zhigang Zhao, Xiaotuo Zhang, Nan Zhou & Yun Zheng
Abstract Background Transposable elements (TE) account for more than 50% of human genome. It has been reported that some types of TEs are dynamically regulated in the reprogramming of human cell lines. However, it is largely unknown whether some TEs in Macaca mulatta are also regulated during the reprogramming of cell lines of monkey. Results Here, we systematically examined the transcriptional activities of TEs during the conversion of Macaca mulatta fibroblast cells to neuroepithelial stem...

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...

The hypermucoviscosity of hypervirulent K. pneumoniae confers the ability to evade neutrophil-mediated phagocytosis

Qi Xu, Xuemei Yang, Edward Wai Chi Chan & Sheng Chen
Hypervirulent Klebsiella pneumoniae (HvKP), which causes highly fatal infections, is a new threat to human health. In an attempt to investigate the underlying mechanisms of resistance to neutrophil-mediated killing and hence expression of high-level virulence by HvKP, we tested the binding affinity of HvKP strains to various types of human cells. Our data showed that HvKP exhibited weaker binding to both lung epithelial cells, intestinal Caco-2 cells and macrophages when compared to the classic, non-hypervirulent...

Folic acid-modified ROS-responsive nanoparticles encapsulating luteolin for targeted breast cancer treatment

Yu Wang, Qianmei Wang, Wei Feng, Qian Yuan, Xiaowei Qi, Sheng Chen, Pu Yao, Qing Dai, Peiyuan Xia, Dinglin Zhang & Fengjun Sun
Luteolin (Lut) is a natural flavonoid polyphenolic compound with multiple pharmacological activities, such as anti-oxidant, anti-inflammatory, and anti-tumor effects. However, the poor aqueous solubility and low bioactivity of Lut restrict its clinical translation. Herein, we developed a reactive oxygen species (ROS)-responsive nanoplatforms to improve the bioactivity of Lut. Folic acid (FA) was employed to decorate the nanoparticles (NPs) to enhance its targeting ability. The size of Lut-loaded ROS-responsive nanoparticles (Lut/Oxi-αCD NPs) and FA-modified Lut/Oxi-αCD NPs...

Early Cretaceous rapid exhumation processes in the southern Great Xing’an Range, NE China: implications for extensional geodynamics

Wen Chen, Wen Zhang, Shuangfeng Zhao, Jingbo Sun, Ze Shen, Qiuyi Du & Zhi Li
The Mesozoic-Cenozoic geological evolution of the southern Great Xing’an Range (GXR) has long been controversial since it is located in the superposed region of different tectonic regimes and involves complex interactions. Here, we present low-temperature thermochronological data from granitoids emplaced in multiple magmatic stages to delineate the tectono-thermal history and further understand the geodynamic process. Most zircon and apatite (U-Th)/He ages, within error, indicate Early Cretaceous: the zircon average (U-Th)/He ages range from 146.7 ±...
