Inhibition of p53 alleviates prostate cell apoptosis in Escherichia coli‑induced bacterial prostatitis.
Inhibition of p53 alleviates prostate cell apoptosis in Escherichia coli‑induced bacterial prostatitis.
Mol Med Rep. 2019 Jun 06;:
Authors: Wang H, Ji Z
Abstract
Previous studies demonstrated that uropathogenic Escherichia coli infection contributes to human bacterial prostatitis. Apoptosis of prostate epithelial cells is closely associated with the progression of bacterial prostatitis. The aim of the present study was to investigate the effect of cellular tumor antigen p53 (p53) on the apoptosis of bacterial prostatitis cells. The prostate epithelial RWPE‑1 cell line was infected with Escherich...

Rac1 GTPase is a critical factor in phagocytosis in the large yellow croaker Larimichthys crocea by interacting with tropomyosin
Publication date: Available online 11 May 2019Source: Fish & Shellfish ImmunologyAuthor(s): Fang Han, Wanbo Li, Xiande Liu, Dongling Zhang, Lanping Liu, Zhiyong WangAbstractThe Rho family GTPase Rac1 acts as a molecular switch for signal transduction to regulate various cellular functions. Here, a Rac1 homolog (LcRac1) was identified in large yellow croaker (Larimichthys crocea), one of the most economically important marine fishes. The LcRac1 protein was expressed in Escherichia coli and purified. Subsequently the specific antibody was raised using the purified fusion protein (GST-LcRac1). LcRac1 was ubiquitously expresse...

Engineered targeting tLyp-1 exosomes as gene therapy vectors for efficient delivery of siRNA into lung cancer cells
In conclusion, the targeting tLyp-1 exosomes are successfully engineered, and can be used for gene therapy with a high transfection efficiency. Therefore, the engineered targeting tLyp-1 exosomes offer a promising gene delivery platform for future cancer therapy.Graphical AbstractThe tLyp-1-lamp2b plasmid transfected HEK293T cells can secreted tumor targeting tLyp-1 exosomes. By electroporation technology, targeting tLyp-1 exosomes were loaded with siRNA. When targeting tLyp-1 exosome ruptured in cytoplasm, siRNA was loaded into the RNA-induced silencing complex (RISC). The sense (passenger) strand was degraded while the a...

Human CAR NK Cells: A New Non-viral Method Allowing High Efficient Transfection and Strong Tumor Cell Killing
In conclusion, the method of NK cell transfection described in our present study is highly efficient, does not require expensive dedicated structures necessary for viral transduction and avoids possible risks associated with the use of viral vectors. Importantly, it may be applied to NK cells or NK-92 cell line, greatly improving their anti-tumor activity and providing a new NK cell-based platform for new protocols of adoptive immuno-therapy of cancer.

NOD2 and TLR2 Signal via TBK1 and PI31 to Direct Cross-Presentation and CD8 T Cell Responses
The objective of this study was to explore the role of NOD2 and TLR2 in cross-presentation in human dendritic cells undertaking an unbiased screen. We have used a quantitative phosphoproteomic analysis by liquid chromatography-tandem mass spectrometry (LC-MS/MS) followed by a computational analysis to identify the proteins as differentially abundant in response to NOD2 and TLR2 sensing. Validation of the phosphoproteomic analysis was performed by the detection of proteins in phosphoenriched lysates and detected by western blot. Techniques for the modulation of gene expression (shRNA and siRNA) were used to confirm the resu...

UBXN1 interacts with the S1 protein of transmissible gastroenteritis coronavirus and plays a role in viral replication
AbstractTransmissible gastroenteritis coronavirus (TGEV) is an enteropathogenic coronavirus that causes diarrhea in pigs and is associated with high morbidity and mortality in sucking piglets. S1 is one of two protein domains in the spike (S) glycoprotein and is responsible for enteric tropism, sialic acid recognition, and host receptor binding. Although there has been extensive research on the S1 protein of TGEV, little is known about the intracellular role of TGEV-S1. In the present study, we used yeast two-hybrid screening of a cDNA library from porcine intestinal cells to identify proteins that interact with TGEV-S1. A...

Endothelial Cell-Derived TGF- β Promotes Epithelial-Mesenchymal Transition via CD133 in HBx-Infected Hepatoma Cells
Conclusion: The study indicates that secretory factors like TGF-β from neighboring endothelial cells may enhance expression of CD133 and impart an aggressive EMT phenotype to HBx-infected hepatoma cells in HBV induced HCC.
Introduction
Hepatocellular Carcinoma (HCC) is one of the most common cancer worldwide, representing approximately 4% of all malignancies (1). It has been estimated that more than 50% of HCC cases in the world are associated with hepatitis B virus (HBV) (2). HBV is a partially double stranded DNA virus belonging to the Hepadnavirus family. The HBV genome is 3.2 kb in size and contains fou...

Autophagy Is a Defense Mechanism Inhibiting Invasion and Inflammation During High-Virulent Haemophilus parasuis Infection in PK-15 Cells
In this study, we sought to investigate whether SH0165 (serovar 5, high-virulent strain) and HN0001 (serovar 6, non-virulent strain) infection induces autophagy and the specific role of autophagy in bacterial invasion and inflammation during H. parasuis infection. Moreover, we explored the mechanism underlying autophagy regulated inflammation through inflammatory signaling cascades during H. parasuis infection. This observation could provide useful information for further understanding the role of autophagy in H. parasuis infection and improve our knowledge of new strategies against this pathogen.

Oligomeric S100A4 Is Associated With Monocyte Innate Immune Memory and Bypass of Tolerance to Subsequent Stimulation With Lipopolysaccharides
Conclusion: Bypass of tolerance by DAMPs might be a phenomenon as important as TI, since it could explain how chronic inflammation can be maintained in spite of an environment with multiple TLR2/TLR4-ligands. In RA monocytes, a PRDM8-dependent TI mechanism could be responsible for sustained chemokine/cytokines levels.
Introduction
Monocytes and macrophages play a central role in the pathophysiology of inflammation. For instance, in rheumatoid arthritis (RA), activated monocytes massively infiltrate synovial tissues and produce tumor necrosis factor-α (TNFα) (1–3). Accordingly, therapies aime...

Plant-Derived Alkaloids: The Promising Disease-Modifying Agents for Inflammatory Bowel Disease
Conclusion
This paper summarizes the current findings regarding the anti-colitis activity of plant-derived alkaloids and shows how these alkaloids exhibit significant and beneficial effects in alleviating colonic inflammation. These natural alkaloids are not only promising agents for IBD treatment but are also components for developing new wonder drugs. However, the underlying molecular mechanisms or toxicological evaluation of most plant-derived alkaloids still require much scientific research, and their actual efficacies for IBD patients have not been verified well in field research. Thus, further clinical trials to elu...

Complement C5b-9 and Cancer: Mechanisms of Cell Damage, Cancer Counteractions, and Approaches for Intervention
In conclusion, osmotic burst of inflated complement-damaged cells may occur, but these bursts are most likely a consequence of metabolic collapse of the cell rather than the cause of cell death.
The Complement Cell Death Mediator: A Concerted Action of Toxic Moieties
Membrane pores caused by complement were first visualized by electron microscopy on red blood cell membranes as large ring structures (22). Similar lesions were viewed on E. coli cell walls (23). Over the years, ample information on the fine ultrastructure of the MAC that can activate cell death has been gathered (24) and has been recently further examined (...
