Synthesis and Anti-Inflammatory Activity of the Natural Cyclooxygenase-2 Inhibitor Axinelline A and Its Analogues.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used medications to treat conditions such as arthritis, pain, and fever. They reduce inflammation by inhibiting cyclooxygenase (COX) enzymes that catalyze the committed step in prostaglandin (PG) biosynthesis. Despite their significant therapeutic benefits, many NSAIDS have undesirable adverse effects.

[Research progress of steroidal saponins in Paris polyphylla var. yunnanensis and their microbial transformation].

Steroidal saponins, important natural organic compounds in Paris polyphylla var. yunnanensis, have good biological activity. Structural modification of steroidal saponins by microbial transformation could produce a large number of products with novel structures and excellent bioactivity, which can provide functional compounds for the research and development of steroidal drugs.

[Traditional use of Paris polyphylla and its active components].

This paper reviewed the traditional use of Paris polyphylla and its active components, aiming to provide reference for the development and utilization of this plant. It was found that P. polyphylla has been used as a medicinal plant by eight ethnic minorities.

RDUR, a lncRNA, Promotes Innate Antiviral Responses and Provides Feedback Control of NF-κB Activation.

Influenza A virus (IAV), a highly infectious respiratory pathogen, remains a major threat to global public health. Numerous long non-coding RNAs (lncRNAs) have been shown to be implicated in various cellular processes. Here, we identified a new lncRNA termed RIG-I-dependent IAV-upregulated noncoding RNA (RDUR), which was induced by infections with IAV and several other viruses.

[Synergistic role of JAK/STAT5 and PI3K/AKT signaling pathways in regulating eIF4B in acute leukemia].

Human acute leukemia (AL) is a clonal malignancy with abnormal hematopoietic stem cells. Clinically, AL is very difficult to cure due to its sudden onset and short course of disease progression. Previous studies have shown that eukaryotic initiation factor 4B (eIF4B) plays a critical role in the development of chronic leukemia.

Identification of an Interferon-Stimulated Long Noncoding RNA (LncRNA ISR) Involved in Regulation of Influenza A Virus Replication.

Long noncoding RNAs (lncRNAs) are involved in a diversity of biological processes. It is known that differential expression of thousands of lncRNAs occurs in host during influenza A virus (IAV) infection. However, only few of them have been well characterized.

Influenza Virus-Induced Robust Expression of SOCS3 Contributes to Excessive Production of IL-6.

Influenza A virus (IAV) remains a major public health threat in the world, as indicated by the severe pneumonia caused by its infection annually. Interleukin-6 (IL-6) involved excessive inflammatory response to IAV infection profoundly contributes to the virus pathogenesis. However, the precise mechanisms underlying such a response are poorly understood.

Evolution and Genetic Diversity of Porcine Circovirus 3 in China.

The identification of a new circovirus (Porcine Circovirus 3, PCV3) has raised concern because its impact on swine health is not fully known. In Fujian Province in eastern China, even its circulating status and genetic characteristics are unclear. Here, we tested 127 tissue samples from swine from Fujian Province that presented respiratory symptoms.

In-depth proteomic analysis of the byssus from marine mussel Mytilus coruscus.

Unlabelled: Mussels attach to various submerged surfaces by using the byssus, which contains different proteins and is a promising source of water-resistant bio-adhesives for potential use in biotechnological and medical applications. The protein composition of the byssus has not yet been fully understood although at least eleven byssal proteins were characterized previously. In order to increase genomic resources and identify new byssal proteins from mussel Mytilus coruscus, high-throughput Illumina sequencing was undertaken on the foot, and 79,997,776 paired-ends reads were generated, yielding a library containing 88,825ft unigenes.
