Alpha anteriorization and theta posteriorization during deep sleep

Yue Cui, Yu Li, Qiqi Li, Jing Huang, more

Journal of Neuroscience Research > 102 > 4 > n/a - n/a

Brain states (wake, sleep, general anesthesia, etc.) are profoundly associated with the spatiotemporal dynamics of brain oscillations. Previous studies showed that the EEG alpha power shifted from the occipital cortex to the frontal cortex (alpha anteriorization) after being induced into a state of general anesthesia via propofol. The sleep research literature suggests that slow waves and sleep spindles...

Frequency‐Sensitivity of the seismic damage to suspended ceilings

Yunxing Feng, Qiqi Li, Zhe Qu

Earthquake Engineering & Structural Dynamics > 52 > 7 > 2006 - 2024

Seismic damage to suspended ceilings was frequently reported even in minor to moderate earthquakes and caused problems to immediate occupancy and quick recovery of buildings. While peak floor acceleration (PFA) has been exclusively used as an intensity measure for suspended ceilings, this study introduces a shake table test on minimum subassemblies of suspended ceilings under sinusoidal excitation...

There is no fusion fascia in the abdomen and extraperitoneal fascia always surrounds the mesentery

Shicai Chen, Guohua Yang, Qiqi Li, Jiangyu Zhang, more

Journal of Anatomy > 242 > 5 > 796 - 805

Toldt's fascia has always been described as a fusion fascia formed by two layers of visceral peritoneum when the mesentery attaches to the posterior abdominal wall. However, there is still no consensus about the mesentery and its surrounding fascia based on the current anatomic theories. This study aimed to determine the anatomical structures of the abdomen and provide a correct surgical plane for...

ZNFX1 antisense RNA1 promotes antiviral innate immune responses via modulating ZNFX1 function

Xin Jia, Meiqi Zhang, Haojia Wang, Cuiqin Cheng, more

Journal of Medical Virology > 95 > 3 > n/a - n/a

Increasing evidence suggests that natural antisense transcriptional lncRNAs regulate their adjacent coding genes to mediate diverse aspects of biology. Bioinformatics analysis of the previously identified antiviral gene ZNFX1 revealed neighboring lncRNA ZFAS1 transcribed on the opposite strand from ZNFX1. Whether ZFAS1 exerts antiviral function via regulating the dsRNA sensor ZNFX1 is unknown. Here...

TGF‐β1 regulates the lncRNA transcriptome of ovarian granulosa cells in a transcription activity‐dependent manner

Qiqi Li, Yangan Huo, Siqi Wang, Liu Yang, more

Cell Proliferation > 56 > 1 > n/a - n/a

Objectives Transforming growth factor β1 (TGF‐β1), an essential cytokine belongs to TGF‐β superfamily, is crucial for female fertility. Increasing evidence show that long noncoding RNAs (lncRNAs) influence the state of granulosa cells (GCs). This study aimed to detect the effects of TGF‐β1 on the lncRNA transcriptome, and investigate whether lncRNAs mediate the functions of TGF‐β1 in GCs. Material...

MiR‐496 promotes migration and epithelial‐mesenchymal transition by targeting RASSF6 in colorectal cancer

Hua Wang, Bianbian Yan, Pan Zhang, Shuzhen Liu, more

Journal of Cellular Physiology > 235 > 2 > 1469 - 1479

Aberrant loss of tumor‐suppressor genes plays a crucial role in tumorigenesis and development of colorectal cancer (CRC). Extensive studies have reported tha hypermethylation of Ras association domain family member 6 (RASSF6) is common in various solid tumors. Another important mode of epigenetic regulation, microRNA (miRNA) regulation of RASSF6, is far from clear. The aim of the present work was...

MicroRNA‐3191 promotes migration and invasion by downregulating TGFBR2 in colorectal cancer

Hongjuan He, Xiaojuan Zhao, Ziqing Zhu, Le Du, more

Journal of Biochemical and Molecular Toxicology > 33 > 6 > n/a - n/a

Mutations in transforming growth factor beta receptor II (TGFBR2) are detected in up to 30% of overall colorectal cancer (CRC). Dysregulation of some microRNAs participated in the CRC pathogenesis. In this study, we used the gene ontology analyses, the Kyoto Encyclopedia of Genes and Genomes pathway analyses and gene set enrichment analysis to indicate that miR‐3191 was involved in the regulation...

Alteration of the tumor suppressor SARDH in sporadic colorectal cancer: A functional and transcriptome profiling‐based study

Hongjuan He, Erfei Chen, Lei Lei, Bianbian Yan, more

Molecular Carcinogenesis > 58 > 6 > 957 - 966

Sporadic colorectal cancer (sCRC) is one of the leading causes of cancer death worldwide. As a highly heterogeneous complex disease, the currently reported classical genetic markers for sCRC, including APC, KRAS, BRAF, and TP53 gene mutations and epigenetic alterations, can explain only some sCRC patients. Here, we first reported a deleterious c.551C>T mutation in SARDH in sCRC. SARDH was identified...

Biomedicine & Pharmacotherapy > 2018 > 106 > C > 1046-1051

MiRNA regulation is a crucial way of epigenetic changes. Mir-32 has been reported in several studies as an oncogene, however, its role and target in colorectal cancer (CRC) remains unclear. In this study, we aimed to explore the role of miR-32 in CRC using bioinformatic analysis and functional assays. We collected 28 pairs of CRC tumor tissues and adjacent normal tissues and confirmed miR-32 was significantly...

Erfei Chen, Qiqi Li, Hua Wang, Fangfang Yang, more

Biomedicine & Pharmacotherapy > 2018 > 106 > C > 1370-1377

Colorectal cancer (CRC) is a leading cause of cancer deaths worldwide. Accumulation of varieties of epigenetic changes, including miRNA regulation, is one of the fundamental processes driving CRC initiation and progression. Mir-92a has been reported in several studies as an oncogene, and particularly in colorectal cancer, it has become a useful biomarker for early detection of CRC in both serum or...

Surface Science > 2018 > 668 > C > 68-72

The chemical reactions of hydrogen gas generation via water splitting on Si-terminated 4H-SiC surfaces with or without C/Si vacancies were studied by using first-principles. We studied the reaction mechanisms of hydrogen generation on the 4H-SiC(0001) surface. Our calculations demonstrate that there are major rearrangements in surface when H₂O approaches the SiC(0001) surface. The first H splitting...
