Chronic PM exposure disrupts intestinal barrier integrity via microbial dysbiosis-triggered TLR2/5-MyD88-NLRP3 inflammasome activation.

Background: PM, a known public health risk, is increasingly linked to intestinal disorders, however, the mechanisms of its impact are not fully understood.

Purpose: This study aimed to explore the impact of chronic PM exposure on intestinal barrier integrity and to uncover the underlying molecular mechanisms.

Methods: C57BL/6 J mice were exposed to either concentrated ambient PM (CPM) or filtered air (FA) for six months to simulate urban pollution conditions.

rNMPID: a database for riboNucleoside MonoPhosphates in DNA.

Motivation: Ribonucleoside monophosphates (rNMPs) are the most abundant non-standard nucleotides embedded in genomic DNA. If the presence of rNMP in DNA cannot be controlled, it can lead to genome instability. The actual regulatory functions of rNMPs in DNA remain mainly unknown.

GlioMarker: An integrated database for knowledge exploration of diagnostic biomarkers in gliomas.

Gliomas are the most frequent malignant and aggressive tumors in the central nervous system. Early and effective diagnosis of glioma using diagnostic biomarkers can prolong patients' lives and aid in the development of new personalized treatments. Therefore, a thorough and comprehensive understanding of the diagnostic biomarkers in gliomas is of great significance.

BioVisReport: A Markdown-based lightweight website builder for reproducible and interactive visualization of results from peer-reviewed publications.

Interactive visualization is an effective way to promote the reproducibility of results presented in biomedical publications and to facilitate additional exploration of the reported data. However, there is a lack of convenient tools that balance reproducibility with ease of use. To address this problem, we develop BioVisReport, a lightweight solution for the rapid generation of an interactive website based on a user-defined Markdown file, which acts as a text markup language without requiring users to master complex syntax and allows them to preview the results in real-time.

Advances in exosome biomarkers for cervical cancer.

Cervical cancer (CC) ranks as the fourth most frequently diagnosed malignancy in females worldwide. Exosomes are a subclass of extracellular vesicles released by nearly all types of cells that act as cargo transport vehicles, carrying proteins, and genetic material (such as miRNAs, long noncoding RNAs, and mRNAs) derived from their parent cells may affect receiving cells and thus have emerged as key players in several biological processes, including inflammatory pathways. In this review, we concentrated on the findings of exosome investigations in CC, particularly their components.

Subchronic exposure to concentrated ambient PM2.5 perturbs gut and lung microbiota as well as metabolic profiles in mice.

Exposure to ambient fine particular matter (PM2.5) are linked to an increased risk of metabolic disorders, leading to enhanced rate of many diseases, such as inflammatory bowel disease (IBD), cardiovascular diseases, and pulmonary diseases; nevertheless, the underlying mechanisms remain poorly understood. In this study, BALB/c mice were exposed to filtered air (FA) or concentrated ambient PM2.

Clinicopathological and prognostic implications of polo-like kinase 1 expression in colorectal cancer: A systematic review and meta-analysis.

Background: Polo-like kinase 1 (PLK1) is a potential prognostic marker in colorectal cancer (CRC). Nevertheless, the clinicopathological and prognostic roles of PLK1 in CRC are still undefined. Therefore, we performed a meta-analysis to investigate the clinicopathological and prognostic relevance of PLK1 expression in CRC patients.

Commensal Microbes Affect Host Humoral Immunity to Infection.

As important players in the host defense system, commensal microbes and the microbiota influence multiple aspects of host physiology. infection is highly contagious among humans. However, the roles of the microbiota in pathogenesis are poorly understood.

Expressing MicroRNA Sponge Drastically Improves the Insecticidal Activity of Baculovirus via Increasing the Level of Ecdysteroid Hormone in Larvae.

is a conserved miRNA highly expressed in insects. We previously showed that the antisense inhibitor (antagomiR) of improved the infection by baculovirus Autographa californica nucleopolyhedrovirus (AcMNPV) in and larvae. Here, we constructed a recombinant AcMNPV (vPH-banS) expressing sponge, an mRNA containing eight antisense binding sites for .

Temporary CXCR3 and CCR5 antagonism following vaccination enhances memory CD8 T cell immune responses.

Although current vaccination strategies have been successful at preventing a variety of human diseases, attempts at vaccinating against some pathogens such as AIDS and tuberculosis (TB) have been more problematic, largely in that abnormally high numbers of antigen specific CD8+ T cells are required for protection. This study assessed the effect of temporarily dampening the chemokine receptor CXCR3 and CCR5 after vaccination on host immune responses by the administration of TAK-779, a small molecule CXCR3 and CCR5 antagonists commonly used to inhibit HIV infection. Our results showed that the use of TAK-779 enhanced memory CD8+ T cell immune responses both qualitatively and quantitatively.

The Effect of MicroRNA bantam on Baculovirus AcMNPV Infection in Vitro and in Vivo.

The role of microRNA bantam, one of the most abundant microRNAs in Sf9 cells, was studied for its role in baculovirus infection in vitro and in vivo. The expression level of bantam was increased after AcMNPV infection in Sf9 cells and in Spodoptera litura larvae. In Sf9 cells, application of bantam inhibitor or mimic altered the expression of many virus genes, the most affected gene being lef8, gp41 and p10, the expression level of which was increased by 8, 10 and 40 times, respectively, in the presence of bantam inhibitor.
