Materials And Methods: The differentially expressed (DE) genes (DEGs) and DE lncRNAs (DELs) from 501 LUSC and 49 normal lung tissues, and DE miRNAs (DEMs) from 478 LUSC and 45 normal lung tissues were respectively obtained via the TCGA database.

MiR-509-3-5p-NONHSAT112228.2 Axis Regulates p21 and Suppresses Proliferation and Migration of Lung Cancer Cells.

Background: Although the involvement of individual microRNA and lncRNA in the regulation of p21 expression has largely been evidenced, less is known about the roles of functional interactions between miRNAs and lncRNAs in p21 expression. Our previous work demonstrated that miR-509- 3-5p could block cancer cell growth.

Methods: To gain an insight into the role of miR-509-3-5p in the regulation of p21 expression, we performed in silico prediction and showed that miR-509-3-5p might target the NONHSAT112228.

Insufficient awareness and vaccination practices for inflammatory bowel disease patients in China: A multi-center survey of Chinese gastroenterologists.

Objective: The prevalence of inflammatory bowel disease (IBD) has been increasing worldwide, and the risk of infection has increased due to the use of immunosuppressive and biologic medications. Some of these infections can be prevented with vaccinations. The aim of this study was to evaluate the vaccination practices of Chinese gastroenterologists for patients with IBD.

Clathrin-dependent endocytosis predominantly mediates protein absorption by fat body from the hemolymph in Bombyx mori.

During insect larval-pupal metamorphosis, proteins in the hemolymph are absorbed by the fat body for the maintenance of intracellular homeostasis; however, the type of proteins and how these proteins are internalized into the fat body are unclear. In Bombyx mori, the developmental profiles of total proteins in the hemolymph and fat body showed that hemolymph-decreased protein bands (55-100 kDa) were in accordance with those protein bands that increased in the fat body. Inhibition of clathrin-dependent endocytosis predominantly blocked the transportation of 55-100 kDa proteins from the hemolymph into the fat body, which was further verified by RNA interference treatment of Bmclathrin.

PP2A inhibition by LB-100 protects retinal pigment epithelium cells from UV radiation via activation of AMPK signaling.

AMP-activated protein kinase (AMPK) signaling activation can inhibit Ultra-violet (UV) radiation (UVR)-induced retinal pigment epithelium (RPE) cell injuries. LB-100 is a novel inhibitor of protein phosphatase 2A (PP2A), the AMPKα1 phosphatase. Here, our results demonstrated that LB-100 significantly inhibited UVR-induced viability reduction, cell death and apoptosis in established ARPE-19 cells and primary murine RPE cells.

Objective: This study aims to study the effect of Rho kinase inhibitor fasudil on the expression endothelin-1 (ET-1) and nitric oxide (NO) in rats with hypoxic pulmonary hypertension (HPH).

Methods: Twenty-four male SD rats were randomly divided into three groups: control group, model group (HPH group) and HPH+fasudil group. The rat HPH model was established by intermittent hypoxia (IH) at atmospheric pressure.

Prediction of phosphorylation sites based on Krawtchouk image moments.

Protein phosphorylation is one of the most pervasive post-translational modifications and regulates diverse cellular processes in organisms. Under the catalysis of protein kinases, protein phosphorylation usually occurred in the residues serine (S), threonine (T), or tyrosine (Y). In this contribution, we proposed a novel scheme (named KMPhos) for the theoretical prediction of protein phosphorylation sites.

[Yield reduction risk based on WOFOST model and water stress for winter wheat in Henan Province, China].

The main wheat production area in Henan Province was classified into five regions based on observed wheat production data, historical meteorological data and soil data from thirty sites du-ring 1981 to 2014. The changes in the risk of yield loss of winter wheat under water stress condition in each region were calculated with WOFOST model. From 1981 to 2014, the yield reduction rate of winter wheat showed an increasing trend at all the sites with the increase rate of 2.

MiR-509-3-5p causes aberrant mitosis and anti-proliferative effect by suppression of PLK1 in human lung cancer A549 cells.

MicroRNAs (miRNAs) are potent post-transcriptional regulators of gene expression and play roles in DNA damage response (DDR). PLK1 is identified as a modulator of DNA damage checkpoint. Although down-regulation of PLK1 by certain microRNAs has been reported, little is known about the interplay between PLK1 and miR-509-3-5p in DDR.

A Type of Low-Latency Data Gathering Method with Multi-Sink for Sensor Networks.

To balance energy consumption and reduce latency on data transmission in Wireless Sensor Networks (WSNs), a type of low-latency data gathering method with multi-Sink (LDGM for short) is proposed in this paper. The network is divided into several virtual regions consisting of three or less data gathering units and the leader of each region is selected according to its residual energy as well as distance to all of the other nodes. Only the leaders in each region need to communicate with the mobile Sinks which have effectively reduced energy consumption and the end-to-end delay.

E2F1 regulates p53R2 gene expression in p53-deficient cells.

The p53R2 gene encoding a small subunit of the ribonucleotide reductase has been identified as a p53-inducible gene. Although this gene is discovered as a target for p53 family proteins, the mechanism underlying p53R2 induction by DNA damage in p53-defiencient cells remains to be elucidated. In this study, we demonstrate that transcription factor E2F1 regulates the p53R2 gene expression in p53-deficient cells.

Comparative genomics of the marine bacterial genus Glaciecola reveals the high degree of genomic diversity and genomic characteristic for cold adaptation.

To what extent the genomes of different species belonging to one genus can be diverse and the relationship between genomic differentiation and environmental factor remain unclear for oceanic bacteria. With many new bacterial genera and species being isolated from marine environments, this question warrants attention. In this study, we sequenced all the type strains of the published species of Glaciecola, a recently defined cold-adapted genus with species from diverse marine locations, to study the genomic diversity and cold-adaptation strategy in this genus.

E2F1-regulated DROSHA promotes miR-630 biosynthesis in cisplatin-exposed cancer cells.

DNA damage may regulate microRNA (miRNA) biosynthesis at the levels of miRNA transcription, processing and maturation. Although involvement of E2F1 in the regulation of miRNA gene activation in response to DNA damage has been documented, little is known about the role of E2F1 in miRNA processing. In this study we demonstrate that E2F1 enhances miR-630 biosynthesis under cisplatin (CIS) exposure through promoting DROSHA-mediated pri-miR-630 processing.
