Prospect and clinical value of oxymatrine in prevention and treatment of pancreatic fibrosis

Studies have confirmed that pancreatic stellate cell activation is the central event in the initiation and development of pancreatic fibrosis (PF), but the specific mechanism of PF is still unknown, and there is no specific treatment for PF. Some basic studies have confirmed that oxymatrine (OMT) has a certain therapeutic effect on PF, but further research is needed. It can be predicted that OMT has a far-reaching research prospect and good clinical application value for the prevention and treatment of PF, and is also conducive to the better development and utilization of traditional Chinese herbal medicine radix sophorae flavescentis.

Traditional uses, phytochemistry, and pharmacological properties of Sophora alopecuroides L

Sophora alopecuroides L., known as ku dou zi in China, has a long history as a traditional Chinese medicine for the treatment of bacillary dysentery, enteritis, hepatitis, and other diseases, and exerts a critical role in anti-tumor. It contains abundant of alkaloids such as oxymatrine, matrine, and total alkaloids, which have been developed in China as anti-disease drugs related with inhibition of the angiogenesis-associated factors, anti-inflammatory response, and regulation of JNK, p38 MAP kinase, and NF-κB signal pathways and so on. The purpose of this review is to take comprehensive summary of the botany, traditional uses, phytochemistry, and pharmacological properties of Sophora alopecuroides L. so as to provide opportunities for further study and clinical application.

Oxymatrine down-regulates VEGF expression in human pancreatic carcinoma SW1990 cells

AIM: To observe the influence of oxymatrine (OM) treatment on vascular endothelial growth factor (VEGF) expression in human pancreatic carcinoma SW1990 cells and to assess the mechanism behind the cytotoxicity of OM against SW1990 cells.

METHODS: Cultured SW1990 cells were divided into two groups: control group and OM group. The OM group was further divided into three subgroups and treated with 1, 2 and 4 g/L OM, respectively. The mRNA and protein expression of VEGF in SW1990 cells was analyzed by real-time polymerase chain reaction (RT-PCR) and Western blot, respectively. The changes in the cytotoxicity of OM against SW1990 cells were assessed by MTT assay. The effect of OM on the invasiveness of SW1990 cells was analyzed using cell invasion assay kit.

RESULTS: The expression levels of VEGF mRNA in SW1990 cells were significantly lower in the three OM subgroups than in the control group (0.648 ± 0.043, 0.395 ± 0.012, 0.317 ± 0.031 vs 0.889 ± 0.028, all P < 0.05). Similar results were obtained for the protein expression of VEGF (1.668 ± 0.212, 1.523 ± 0.345, 1.388 ± 0.187 vs 1.876 ± 0.327, all P < 0.05). The invasion of SW1990 cells in the OM subgroups was markedly lower than that in the control group (325 ± 64.43, 206 ± 84.76, 124 ± 46.78 vs 498 ± 78.54, all P < 0.05).

CONCLUSION: OM is able to reduce the invasion of SW1990 cells possibly by down-regulating the expression of VEGF.
