Long non-coding RNA TRPM2 antisense RNA as a potential therapeutic target promotes tumorigenesis and metastasis in esophageal cancer

Wei Wang, Yukai Dai, Xin Yang & Xinming Xiong
Esophageal cancer (EC) is one type of aggressive gastrointestinal cancers. The treatment of EC is challenging. Effective therapeutic targets require development. Long non-coding RNA TRPM2 antisense RNA (LncRNA TRPM2-AS) is considering a novel biomarker and therapeutic target for various types of cancer. However, the role of lncRNA TRPM2-AS in EC remains unknown. This study aimed to illustrate effects of LncRNA TRPM2-AS on EC growth and metastasis and potential underlying molecular mechanisms. LncRNA TRPM2-AS expression was...

Sodium houttuyfonate enhances the mono-therapy of fluconazole on oropharyngeal candidiasis (OPC) through HIF-1α/IL-17 axis by inhibiting cAMP mediated filamentation in Candida albicans-Candida glabrata dual biofilms

Mengli Chen, Ting Cheng, Chen Xu, Min Pan, Jiadi Wu, Tianming Wang, Daqiang Wu, Guiming Yan, Changzhong Wang & Jing Shao
Candida albicans and Candida glabrata are two common opportunistic fungi that can be co-isolated in oropharyngeal candidiasis (OPC). Hypha is a hallmark of the biofilm formation of C. albicans, indispensable for the attachment of C. glabrata, which is seldom in mycelial morphology. Increasing evidence reveals a hypoxic microenvironment in interior fungal biofilms, reminding of a fact that inflammation is usually accompanied by oxygen deprivation. As a result, it is assumed that the disaggregation of hypha-mediated...

Serum vancomycin levels predict the short-term adverse outcomes of peritoneal dialysis–associated peritonitis

Ying Ma, Yingzhou Geng, Li Jin, Xiaopei Wang, Changna Liang, Liyi Xie, Wanhong Lu & Jing Lv
Background:The role of monitoring serum vancomycin levels during treatment of peritoneal dialysis (PD)–associated peritonitis is controversial. Substantial inter-individual variability may result in suboptimal serum levels despite similar dosing of vancomycin. The published predictors of suboptimal serum vancomycin levels remain limited.Methods:Data were retrospectively collected from 541 patients on continuous ambulatory peritoneal dialysis between 1 January 2018 and 31 December 312019. For gram-positive cocci and culture-negative peritonitis, we adopted a vancomycin administration and monitoring protocol. Short-term adverse...

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...

A transcriptomic analysis of neuropathic pain in the anterior cingulate cortex after nerve injury

Yu Zhang, Shiwei Jiang, Fei Liao, Zhifeng Huang, Xin Yang, Yu Zou, Xin He, Qulian Guo & Changsheng Huang
The anterior cingulate cortex (ACC) is a core brain region processing pain emotion. In this study, we performed RNA sequencing analysis to reveal transcriptomic profiles of the ACC in a rat chronic constriction injury (CCI) model. A total of 1628 differentially expressed genes (DEGs) were identified by comparing sham-operated rats with rats of 12 hours, 1, 3, 7, and 14 days after surgery, respectively. Although these inflammatory-related DEGs were generally increased after CCI, different kinetics...

Yongqi Yue, Yonglin Hua, Jing Zhang, Yu Guo, Dan Zhao, Wentao Huo, Yan Xiong, Fenfen Chen, Yaqiu Lin, Xianrong Xiong & Jian Li
The domestic yak was regarded as a valuable model to explore the molecular mechanism of high-altitude animal adaptation, including the extreme tolerance of starvation and cold stress, which is closely associated with specifically seasonal deposition and metabolism of subcutaneous adipose tissue. However, the key regulators for these processes remain largely unknown. Here, the yak adipogenesis model in vitro was established and liver kinase b1 (LKB1) was regarded as a key negative regulator involved in yak...

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...

SPRY4 promotes adipogenic differentiation of human mesenchymal stem cells through the MEK–ERK1/2 signaling pathway

Na Li, Yunfei Chen, Haiyan Wang, Jing Li & Robert Chunhua Zhao
Obesity is a chronic metabolic disorder characterized by the accumulation of excess fat in the body. Preventing and controlling obesity by inhibiting the adipogenic differentiation of mesenchymal stem cells (MSCs) and thereby avoiding the increase of white adipose tissue is safe and effective. Recent studies have demonstrated that Sprouty proteins (SPRYs) are involved in cell differentiation and related diseases. However, the role and mechanism of SPRY4 in MSC adipogenic differentiation remain to be explored. Here,...

The Cauchy Combination Test under Arbitrary Dependence Structures

Mingya Long, Zhengbang Li, Wei Zhang & Qizhai Li
Combining individual p-values to perform an overall test is often encountered in statistical applications. The Cauchy combination test (CCT) (Journal of the American Statistical Association, 2020, 115, 393–402) is a powerful and computationally efficient approach to integrate individual p-values under arbitrary dependence structures for sparse signals. We revisit this test to additionally show that (i) the tail probability of the CCT can be approximated just as well when more relaxed assumptions are imposed on individual...
