- Paper Abstract
- Ulcerative colitis (UC) is a type of chronic disease of inflammation, and matrine has anti-inflammatory activity. However, it is unclear that whether matrine can alleviate UC. This study aimed to evaluate the effect of matrine on DSS-induced intestinal epithelial cell injury. Cell viability was performed by MTT assay. Then cell apoptosis was analyzed using the TUNEL assay and flow cytometry. The levels of interleukin (IL)-2, IL-6, TNF-α, and IL-1β were evaluated using qRT-PCR. Myeloperoxidase (MPO) activity was detected using ELISA assay. Nitric oxide (NO) production was detected by the Griess reagent. Bax, cleaved caspase-3, Bcl-2, JAK2, p-JAK2, STAT3, p-STAT3, STAT5, p-STAT5 levels were measured by Western blot. Bax (6A7) was asses using immunoprecipitation and immunofluorescence assays. The results illustrated that cell viability was inhibited as the concentration of DSS increased. Matrine did not affect cell viability at the concentration of 0-2 mg/ml but inhibited cell viability in a time-independent manner. Matrine suppressed the levels of pro-inflammatory factors, MPO activity, NO production, and apoptosis of DSS-stimulated cells. Furthermore, we found that matrine inhibited the levels of p-JAK2/JAK2 and p-STAT3/STAT3 but did not affect p-STAT5/STAT5. AG490 treatment further enhanced the effect of matrine on the apoptosis and pro-inflammatory factor levels in DSS-induced cells. In summary, matrine protected NCM460 cell against injury by inactivating the JAK2/STAT3 pathway. These data suggested for the first time that matrine may effective in treating UC.
