Research Progress on Structure-Activity Relationship of 1,8-Naphthalimide DNA Chimeras Against Tumor.

The development of 1,8-naphthalimide derivatives as cell probes, DNA targeting agents, and anti-tumor drugs is one of the research hotspots in the field of medicine. Naphthalimide compounds are a kind of DNA embedder, which can change the topological structure of DNA by embedding in the middle of DNA base pairs, and then affect the recognition and action of topoisomerase on DNA. Aminofide and mitonafide are the first 2 drugs to undergo clinical trials.

Study on the detection of anthrax by ICP-MS based on gold nanoparticle labeling.

Background: In recent years, inductively coupled plasma mass spectrometry (ICP-MS) has been widely used in the field of molecular biology because of its unique advantages. Anthrax is a widespread and long-standing infectious disease, which affects and restricts people's work and life seriously.

Objective: The study goal is to develop a new method for the detection of anthrax.

First Detection of Mukawa Virus in and in China.

Mukawa virus (MKWV), a novel tick-borne virus (TBV) of the genus of family , has been firstly reported in in Japan. In this study, we made an epidemiological investigation in China to obtain the geographic distribution and genetic features of this virus outside Japan. We screened 1,815 adult ticks (665 , 336 , 599 , 170 , 45 ) and 805 wild small mammals collected from eight provinces.

Investigating the inotropic effect of pyruvic acid on the isolated rat heart and its underlying mechanism.

Pyruvic acid is important organic chemical intermediates that plays a role in cardiomyocyte pathophysiology and therapy. This study sought to explore the inotropic effects of pyruvic acid on the function of the isolated rat hearts and investigate its underlying mechanism. Pyruvic acid produced a greater negative inotropic effect compared to HCl and sodium pyruvate in a concentration-dependent pattern in the hearts.

Formic acid up-regulates vascular tension through nitric oxide-cGMP signaling pathway.

Formic acid is a common organic acid used in many industrial processes. There is a paucity of research on the direct toxicity of formic acid and how it might affect the cardiovascular system. This study aimed to understand the effect of formic acid on vascular tension in an animal model and the underlying mechanism.

The interaction between the PARP10 protein and the NS1 protein of H5N1 AIV and its effect on virus replication.

Background: During the process that AIV infect hosts, the NS1 protein can act on hosts, change corresponding signal pathways, promote the translation of virus proteins and result in virus replication.

Results: In our study, we found that PARP domain and Glu-rich region of PARP10 interacted with NS1, and the presence of NS1 could induce PARP10 migrate from cytoplasm to nucleus. NS1 high expression could reduce the endogenous PARP10 expression.

Interaction of influenza virus NS1 protein with growth arrest-specific protein 8.

NS1 protein is the only non-structural protein encoded by the influenza A virus, and it contributes significantly to disease pathogenesis by modulating many virus and host cell processes. A two-hybrid screen for proteins that interact with NS1 from influenza A yielded growth arrest-specific protein 8. Gas8 associated with NS1 in vitro and in vivo.

[Analysis of PARP10 tissue expression profile, interactive protein and UV stress reaction].

One pair of primers were designed and synthesized based on the cDNA sequence encoding Homo sapiens poly (ADP-ribose) polymerase family, member 10 (PARP10) reported on the GenBank. The cDNA sequence encoding PARP10 was cloned from 293FT cell by RT-PCR. Then the RT-PCR product was cloned into pCMV-Myc and pEGFP-C1 plasmids.

[Effect of influenza virus NS1 protein on host cell].

NS1 is a non-structural protein of the influenza A virus, which could only be expressed when cells are infected. The effect of NS1 protein on host cell is still not clear. To understand the role of NS1 protein in cell infection, recombinant plasmid pCMV-myc-NS1 was constructed, and then transfected into A549 cells.
