All the studies that investigated the association between TNF-a polymorphisms and Schizophrenia published before 15 October 2020 were included in. The literature were comprehensively searched and identified in 2 English databases and 2 Chinese databases. The...

Vascular smooth muscle cell-derived hydrogen sulfide promotes atherosclerotic plaque stability via TFEB (transcription factor EB)-mediated autophagy

Zhenzhen Chen, Chenxi Ouyang, Haizeng Zhang, Yuanrui Gu, Yue Deng, Congkuo Du, Changting Cui, Shuangyue Li, Wenjie Wang, Wei Kong, Jingzhou Chen, Jun Cai & Bin Geng
Vascular smooth muscle cells (VSMCs) contribute to plaque stability. VSMCs are also a major source of CTH (cystathionine gamma-lyase)-hydrogen sulfide (H2S), a protective gasotransmitter in atherosclerosis. However, the role of VSMC endogenous CTH-H2S in pathogenesis of plaque stability and the mechanism are unknown. In human carotid plaques, CTH expression in ACTA2+ cells was dramatically downregulated in lesion areas in comparison to non-lesion areas. Intraplaque CTH expression was positively correlated with collagen content, whereas there was...

Long intergenic non-protein coding RNA 1273 confers sorafenib resistance in hepatocellular carcinoma via regulation of methyltransferase 3

Huifang Kong, Jie Sun, Wei Zhang, Huixin Zhang & Hong Li
Hepatocellular carcinoma (HCC) is often diagnosed in patients with advanced disease who are ineligible for curative surgical therapies. Sorafenib is a first-line agent approved for the treatment of advanced HCC. However, the frequent resistance of HCC cells to sorafenib greatly reduces its efficacy. Herein, we describe a novel long non-coding RNA (lncRNA) conferring sorafenib resistance. Long intergenic non-protein coding RNA 1273 (LINC01273) was significantly overexpressed in human HCC and sorafenib-resistant tissues, linking it to poor...

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...

Shisong Jing, Xinran Ren, Li Wang, Xiangri Kong, Xingye Wang, Xiren Chang, Xuerui Guo, Yan Shi, Jiyu Guan, Tiedong Wang, Bingmei Wang, Wu Song & Yicheng Zhao
The resistance of Staphylococcus aureus (S. aureus) to various antibiotics has increased dramatically due to the misuse of antibiotics, and thus the development of new anti-infective drugs with new targets is urgently needed to combat resistance. Caseinolytic peptidase P is a case in hydrolase that regulates the virulence level of S. aureus. Here, we found that nepetin, a small-molecule compound from traditional Chinese herbal flavonoids, effectively inhibits ClpP activity. Nepetin suppressed the virulence of S....

A hexagon-based method for polygon generalization using morphological operators

Lu Wang, Tinghua Ai, Dirk Burghardt, Yilang Shen & Min Yang
Numerous methods based on square rasters have been proposed for polygon generalization. However, these methods ignore the inconsistent distance measurement among neighborhoods of squares, which may result in an imbalanced generalization in different directions. As an alternative raster, a hexagon has consistent connectivity and isotropic neighborhoods. This study proposed a hexagon-based method for polygon generalization using morphological operators. First, we defined three generalization operators: aggregation, elimination, and line simplification, based on hexagonal morphological operations. We...

TET2 regulates osteoclastogenesis by modulating autophagy in OVX-induced bone loss

Chen Yang, Huaqiang Tao, Haifeng Zhang, Yu Xia, Jiaxiang Bai, Gaoran Ge, Wenming Li, Wei Zhang, Long Xiao, Yaozeng Xu, Zhirong Wang, Ye Gu, Huilin Yang, Yu Liu & Dechun Geng
Increased bone resorption by osteoclasts after estrogen deficiency is the main cause of postmenopausal osteoporosis. TET2 (tet methylcytosine dioxygenase 2) is a DNA demethylase that regulates cellular function and differentiation potential. Macroautophagy/autophagy maintains cellular homeostasis by recycling unnecessary and damaged organelles. This study revealed that TET2 promoted bone loss in oophorectomized (OVX) mice and that TET2 promoted osteoclast differentiation by regulating autophagy. Tet2 knockdown inhibited autophagy and osteoclast differentiation in vitro. Mechanistically, Tet2 knockdown increased...

Steffan Noe Christiansen, Jeppe Dyrberg Andersen, Marie-Louise Kampmann, Jing Liu, Mikkel Meyer Andersen, Jacob Tfelt-Hansen & Niels Morling
The Infinium MethylationEPIC BeadChip (EPIC) is a reliable method for measuring the DNA methylation of more than 850,000 CpG positions. In clinical and forensic settings, it is critical to be able to work with low DNA amounts without risking reduced reproducibility. We evaluated the EPIC for a range of DNA amounts using two-fold serial dilutions investigated on two different days. While the β-value distributions were generally unaffected by decreasing DNA amounts, the median squared Pearson’s...

Modulation of Atg genes expression in aged rat liver, brain, and kidney by caloric restriction analyzed via single-nucleus/cell RNA sequencing

Chuanbin Yang, Siyu Xia, Wei Zhang, Han-Ming Shen & Jigang Wang
Dysregulation of macroautophagy/autophagy has been closely implicated in aging. Caloric restriction (CR) is an effective intervention of aging partially via activation of autophagy. Recently, a high-throughput single-cell RNA-seq technique has been employed to detect the comprehensive transcriptomes of individual cells. However, the transcriptional networks of ATG (autophagy related) genes in the aging process and the modulation of ATG genes expression by CR at the single-cell level have not been elucidated. Here, by performing data analysis...
