结论
2

Objective
2
To investigate the effect of pulsatilla saponin A (PSA) on proliferation and apoptosis of human Burkitt lymphoma (BL) cell line Raji cells and expression of related pathway proteins.
Method
2
With Raji cells as the research object, the cell proliferation was detected by cell counting kit-8 (CCK-8) method, and the half-maximal inhibitory concentration (IC
50
) values of 24 h, 48 h and 72 h were calculated to be 19.77, 18.31, 16.70 μmol·L
-1
, respectively. In subsequent related experiments, 0, 8, 16, 32 μmol·L
-1
PSA were selected according to the IC
50
value of Raji cells treated with PAS for 72 h. After 0, 8, 16, 32 μmol·L
-1
PSA acted on Raji cells for 24, 48, 72 h, the optical density values of cell growth curve were detected by CCK-8 method. The zymogen activities of cysteine aspartate-specific protease (Caspase)-3, Caspase-8 and Caspase-9 in Raji cells treated with 0, 8, 16 and 32 μmol·L
-1
PSA for 24 h were measured by Caspase-3, Caspase-8 and Caspase-9 colorimetric assay kit. The apoptosis rate and cell cycle of Raji cells treated with different concentrations of PSA after 24 h were detected by flow cytometry. The expression of B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein (Bax), cleaved poly(ADP-ribose) polymerase (cleaved PARP), cleaved cysteinyl aspartate-specific protease-3 (cleaved Caspase-3) apoptosis related protein and Janus kinase 2 (JAK2), signal transducer and activator of transcription 3 (STAT3), phosphorylated-JAK2 (p-JAK2), and phosphorylated- STAT3 (p-STAT3) pathway proteins in Raji cells after 24 h of treatment with 0, 8, 16 and 32 μmol·L
-1
PSA were tested by Western blot.
Result
2
Compared with control group, decreased cell survival rate, inhibited cell proliferation, activated zymogens of Caspase-3, Caspase-8 and Caspase-9 (
P
<
0.01), increased apoptosis (
P
<
0.05,
P
<
0.01), and enhanced cell cycle arrest in Gap phase 2 (G
2
) were observed in 8, 16 and 32 μmol·L
-1
PSA groups(
P
<
0.05,
P
<
0.01). Compared with control group, cells treated with 8, 16 and 32 μmol·L
-1
PSA had lower expression of Bcl-2, p-JAK2, p-STAT3 proteins (
P
<
0.05,
P
<
0.01), and higher expression of Bax, cleaved PARP and cleaved Caspase-3 protein (
P
<
0.01), while no significant change was found in the expression of JAK2 and STAT3 proteins.
Conclusion
2
PSA could inhibit proliferation and induce apoptosis of Raji cells, and its potential mechanism might be related to the regulation of JAK2/STAT3 signaling pathway.
