Аннотация
BACKGROUND: Fangchinoline (Fan) is extracted from traditional Chinese medicine (called Fangji), or the root of Stephania tetrandra Moore. Fangji is well-known in Chinese medical literature for treating rheumatic diseases. Sjogren's syndrome (SS) is a rheumatic disease whose progression can be mediated via CD4+ T cell infiltration.
OBJECTIVE: This study identifies the potential role of Fan in inducing apoptosis in Jurkat T cells.
METHODS: First, we explored the biological process (BP) associated with SS development by performing a gene ontology analysis of SS salivary gland-related mRNA microarray data. The effect of Fan on Jurkat cells was investigated by analyzing the viability, proliferation, apoptosis, reactive oxygen species (ROS) production, and DNA damage.
RESULTS: Biological process analysis showed that T cells played a role in salivary gland lesions in patients with SS, indicating the significance of T cell inhibition in SS treatment. Viability assays revealed that the half-maximal inhibitory concentration of Fan was 2.49 μM in Jurkat T cells, while the proliferation assay revealed that Fan had an inhibitory effect on the proliferation of Jurkat T cells. The results of the apoptotic, ROS, agarose gel electrophoresis, and immunofluorescence assays showed that Fan induced oxidative stress-induced apoptosis and DNA damage in a dosedependent manner.
CONCLUSION: These results indicate that Fan could significantly induce oxidative stress-induced apoptosis and DNA damage and inhibit the proliferation of Jurkat T cells. Moreover, Fan further enhanced the inhibitory effect on DNA damage and apoptosis by inhibiting the pro-survival Akt signal.
