ABSTRACT The cytidine deaminase APOBEC3G (A3G) exerts a multifaceted antiviral effect against HIV-1 infection. First, A3G was shown to be able terminate HIV infection by deaminating the cytosine residues uracil in minus strand of viral DNA during reverse transcription. Also, number studies have indicated that inhibits transcription non-editing-mediated mechanism. However, mechanism which directly disrupts is not fully understood. In present study, using cell-based coimmunoprecipitation...

The decline of clinically effective antibiotics has made it necessary to develop more antimicrobial agents, especially for refractory biofilm-related infections. Silver nanoparticles (AgNPs) are a new type agent that can eradicate biofilms and reduce bacterial resistance, but its anti-biofilm mechanism not been elucidated. In this study, we investigated the molecular AgNPs against multidrug-resistant Pseudomonas aeruginosa by means tests, scanning electron microscopy (SEM), tandem mass tag...

Abstract As the Human Microbiome Project (HMP) progresses, relationship between microbes and human health has been receiving increasing attention. A growing number of reports support correlation cancer microbes. However, most studies have focused on bacteria, rather than fungal communities. In this study, we studied alteration in lung mycobiome patients with non-small-cell (NSCLC) using metagenomic sequencing qPCR. The higher diversity more complex network were observed NSCLC. addition,...

Since May 2022, the has rapidly spread across world some imported case was confirmed sporadically China. Under these circumstances, data of cases were collected consecutively Chengdu, southwest China to investigate clinical epidemiological characteristics. In study, 28 male patients have infection, with 26 identifying as MSM (men who sex men). Typical lesions...

Differentially expressed microribonucleic acids (miRNAs) in the placenta and circulating exosomes are of diagnostic value for gestational diabetes mellitus (GDM). In a cross-sectional study, we identified miRNAs both pregnant women with GDM, estimated their value.Next-generation sequencing was used to identify that were differentially between GDM normal glucose tolerance pregnancies. Quantitative polymerase chain reaction validate targets. Western blot transmission electron microscopy...

Dietary habits have been proven to help alter the composition of gut microbiota, and exploring impact nutritional patterns on microbiota changes can protect health. However, few studies focused dietary over an experimental timeframe. In this study, 16S rRNA gene sequencing was employed investigate mice under different patterns, including AIN-93G diet (Control), high protein (HPD), fiber (HFD), switch (Switch). The alpha diversity HPD group significantly decreased, but HFD restore decline....

Abstract In the bone immune microenvironment, cells can regulate osteoblasts through a complex communication network. Macrophages play central role in mediating osteogenesis, exosomes derived from them have osteogenic regulation and be used as carriers tissue engineering. However, there are problems with exosomal therapy alone, such poor targeting, content of loaded molecules cannot reach therapeutic concentration. this study, macrophage-derived modified miR-365-2-5p were developed to...

ABSTRACT The switch of Kaposi's sarcoma-associated herpesvirus (KSHV) from latency to lytic replication is a key event for viral dissemination and pathogenesis. MLN4924, novel neddylation inhibitor, reportedly causes the onset KSHV reactivation but impairs later phases program in infected cells. Thus far, molecular mechanism involved modulation cycle by MLN4924 not yet fully understood. Here, we confirmed that treatment different KSHV-infected primary effusion lymphoma (PEL) cell lines with...
