Cuticular proteins (CPs) are implicated in insecticide resistance in mosquito populations. Here, we investigated the role of cuticular genes in regulation of insecticide resistance in Culex pipiens pallens. We identified two CpCPRs (CpCPR63 and CpCPR47) that exhibited higher transcript levels in pyrethroid-resistant strains than in susceptible strains. Mosquito mortality was increased after knockdown of CpCPR genes by dsRNA injection. The RNA interference experiment suggested an interaction between CpCPR63 and CpCPR47, as silencing of one gene resulted in decreased expression of the other...

Long-term use of inorganic nitrogen (N) fertilization has greatly influenced the bacterial community in black soil of northeast China. It is unclear how N affects the bacterial community in two successive crop seasons in the same field for this soil type. We sampled soils from a long-term fertilizer experimental field in Harbin city with three N gradients. We applied sequencing and quantitative PCR targeting at the 16S rRNA gene to examine shifts in bacterial communities and test consistent shifts and driving-factors bacterial responses to elevated N additions...

Colorectal cancer (CRC) is a common malignant tumor, in which the inflammatory microenvironment plays an important role. STAT3 signaling pathway is regarded as the "bridge" between inflammation and cancer, and involved in the development of CRC. SOCS3 is a key negative feedback regulator of JAK/STAT signaling pathway. Studies about SOCS3 gene in CRC are rarely reported. The purpose of this study is to determine the expression of SOCS3 in CRC tissue and its correlation with the clinical pathological characteristics and prognosis of colorectal cancers...

hOGG1 plays a role in several disease pathways, including various cancers. Despite such functional importance, how hOGG1 is regulated at the transcriptional level in human non-small cell lung cancer (NSCLC) remains unknown, particularly via DNA methylation changes. We obtained NSCLC tissues and adjacent non-cancerous tissues and examined hOGG1 mRNA expression levels. NSCLC cells were treated with 5-Aza to test whether DNA methylation can influence the expression of hOGG1. The MassARRAY EpiTYPER and luciferase reporter gene assays were used to define the functional region of the hOGG1 gene (including CpG sites)...

The CRISPR/Cas9 system is an efficient gene-editing method, but the majority of gene-edited animals showed mosaicism, with editing occurring only in a portion of cells. Here we show that single gene or multiple genes can be completely knocked out in mouse and monkey embryos by zygotic injection of Cas9 mRNA and multiple adjacent single-guide RNAs (spaced 10-200 bp apart) that target only a single key exon of each gene. Phenotypic analysis of F0 mice following targeted deletion of eight genes on the Y chromosome individually demonstrated the robustness of this approach in generating knockout mice...

BACKGROUND: Placenta accreta (PA), a severe complication during delivery, is closely linked with massive hemorrhage which could endanger the lives of both mother and baby. Moreover, the incidence of PA has increased dramatically with the increasing rate of cesarean deliveries in the past few decades. Therefore, studies evaluating the effects of different perioperative managements based on different modalities in the treatment of PA are necessary. Among the numerous treatment measures, prophylactic abdominal aortic balloon occlusion (AABO) in combination with cesarean section for PA seems to be more advantageous than others...

MicroRNAs (miRNAs) are short, non-protein-coding RNAs and transcripts that are 18-24 nt in length. miR-204 was first identified as an anti-oncogene and is reported to be downregulated in non-small cell lung cancer, glioma, gastric and thyroid cancer. Recent studies have proposed that a low level of miR-204 expression is associated with tumor progression and disease outcome in breast cancer. Forkhead box A1 (FOXA1), a transcription factor, plays a crucial role in breast cancer and has been predicted as a target of miR-204...

Chronic inflammation plays important roles in cancer initiation and progression. Resolving chronic inflammation or blocking inflammatory signal transduction may prevent cancer development. Here, we report that the combined low-dose use of two anti-inflammatory drugs, aspirin and triptolide, reduces spontaneous lung cancer incidence from 70% to 10% in a mouse model. Subsequent studies reveal that such treatment has little effect in resolving chronic inflammatory conditions in the lung, but it significantly blocks NF-κB-mediated expression of proliferation and survival genes in cancer cells...

Large-scale ecological restoration programs are considered as one of the key strategies to enhance ecosystem services. The Headstream region of Yangtze River (HYZR), which is claimed to be China's Water Tower but witnessed the rapid grassland deterioration during 1970s-2000, has seen a series of grassland restoration programs since 2000. But few studies have thoroughly estimated the hydrological effect of this recent grassland restoration. Here we show that restoration significantly reduces growing-season water yield coefficient (WYC) from 0...

The dominant Vγ2Vδ2 T cell subset recognizes phosphoantigen and exists only in humans and nonhuman primates. Despite the discovery of γδ T cells >30 y ago, a proof-of-concept study has not been done to prove the principle that the Vγ2Vδ2 T cell subset is protective against Mycobacterium tuberculosis and other infections. In this study, we used an adoptive cell-transfer strategy to define the protective role of Vγ2Vδ2 T cells in a primate tuberculosis (TB) model. Vγ2Vδ2 T cells for adoptive transfer displayed central/effector memory and mounted effector functions, including the production of anti-M...
