The co-infection of porcine reproductive respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV2) is quite common in clinical settings and no effective treatment to the co-infection is available. In this study, we established the porcine alveolar macrophages (PAM) cells model co-infected with PRRSV/PCV2 with modification in vitro, and investigated the antiviral activity of Matrin...

Matrine is one of the main bioactive alkaloids of Sophora flavescens Aiton, which has been widely used to treat various diseases in China. These diseases include viral hepatitis, liver fibrosis, cardiac arrhythmia, skin diseases, and tumors. However, matrine is also the main toxic compound of this herb, and the available biomarkers are not reliable in detecting or quantifying matrine risk. Meta...

It has been well documented that matrine, a tetracyclo-quinolizindine alkaloid, possessed a positive inotropic effect. However, the underlying mechanisms at the cellular and ion channel levels have not been completely clarified. Therefore, the present study was designed to identify the cellular target and the mechanisms of inotropic effect of matrine. Guinea pig papillary muscles were used to s...

Non-small cell lung cancer (NSCLC) is the leading cause of cancer-associated mortality in the United States. Chemotherapy prolongs survival rates among patients with advanced disease, however, this is at the cost of clinically significant adverse effects. Matrine is an active component of traditional Chinese medicine and is a promising alternative drug for the treatment of NSCLC. In the present...

Different endophytes isolated from the seeds of Sophora flavescens were tested for their ability to produce matrine production. Response surface methodology (RSM) was applied to optimize the medium components for the endophytic fungus. Results indicated that endophyte Aspergillus terreus had the ability to produce matrine. The single factor tests demonstrated that potato starch was the best car...

The aim of this study was to investigate the protective effects of matrine on lipopolysaccharide (LPS)-induced inflammation and oxidative stress in vivo and in vitro. The results showed that matrine improved intestinal inflammatory status and oxidative balance and enhanced chemokine receptor 7 (CCR7) expression. In LPS-challenged mice and Caco-2 cells, matrine alleviated LPS-induced inflammatio...

The induction of apoptosis-resistant rheumatoid synovial tissue cells has been related to constitutively active Janus kinase/signal transducers and activators of transcription (JAK/STAT) signaling in rheumatoid arthritis (RA). The excessive proliferation and inherent resistance to apoptosis of fibroblast-like synoviocytes (FLS) is an important mechanism by which RA originates. However, the effe...

OBJECTIVE To observe the effects of matrine on proliferation and apoptosis of human renal cell carcinoma cell line GRC-1 in vitro, and to explore its mechanism. METHODS The human renal cell carcinoma cell line GRC-1 was treated with matrine of different concentrations for 24, 48, 72 and 96 h respectively. The MTT assay was used to evaluate the cytotoxic effects of matrine on GRC-1 cells. The ...

BACKGROUND Many studies have investigated the efficacy and safety of matrine in treating malignant pleural effusion by thoracic perfusion. This study is an analytic value of available evidence. METHODS Twelve studies were analyzed in this study. Pooled odds ratios and hazard ratio with 95 % confidence intervals were calculated using the fixed effects model. RESULTS Overall response rate of ...

Matrine may be protective against colorectal cancer (CRC), but how it may work is unclear. Thus, we explored the underlying mechanisms of matrine in CRC. Matrine-related proteins and CRC-related genes and therapeutic targets of matrine in CRC were predicted using a network pharmacology approach. Five targets, including interleukin 6 (IL-6), the 26S proteasome, tumor necrosis factor alpha (TNF-α...
