结果
2
与空白组比较,血小板诱导组吸光度
A
570
显著升高(
P
<
0.01);血小板+丹参注射液组
A
570
则较血小板诱导组显著降低(
P
<
0.01),且与丹参注射液组比较,经血小板诱导的同剂量丹参注射液组细胞增殖抑制率更显著(
P
<
0.01)。与空白组比较,血小板诱导组集落数明显增加(
P
<
0.05);血小板+丹参注射液的集落数则明显低于血小板诱导组(
P
<
0.05,
P
<
0.01)。与空白组比较,血小板诱导组上清液中TGF-
β
1
含量显著升高(
P
<
0.01);血小板+丹参注射液组TGF-
β
1
含量显著降低(
P
<
0.01);与丹参注射液(24 g·L
-1
)组比较,经血小板诱导的同剂量丹参注射液组抑制率更高(
P
<
0.01)。与空白组比较,经丹参注射液处理的血小板上清中TGF-
β
1
明显减少(
P
<
0.05,
P
<
0.01);经丹参注射液处理的SKOV3上清中TGF-
β

的含量差异无统计学意义。与空白组比较,SKOV3细胞上清液诱导组的血小板聚集、血栓素A
2
(TXB
2
)和5-羟色胺(5-HT)分泌显著升高(
P
<
0.01),细胞上清液诱导+丹参注射液组上述指标均显著降低(
P
<
0.01),且与丹参注射液(24 g·L
-1
)组比较,经细胞上清液诱导的同剂量丹参注射液组抑制率更高(
P

结论

丹参注射液可通过抑制血小板与肿瘤细胞相互作用从而对SKOV3细胞增殖产生的影响,其作用机制可能与抑制血小板分泌TGF-
β

有关。
Objective
2
To investigate the inhibitory effects of Danshen injection against ovarian cancer cell proliferation induced by the interaction between platelets and cancer cells.
Method
2
The induction of platelets on SKOV3 growth
in vitro
and the inhibitory effect of Danshen injection at 12,24,and 48 g·L
-1
were observed by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and cell colony formation assays. The content of transforming growth factor-
β
1
(TGF-
β
1
) in the platelet-tumor cell interaction system and platelet supernatant and the effect of Danshen injection on TGF-
β
1
secretion were detected by enzyme-linked immunosorbent assay (ELISA). The influences of tumor cell culture supernatant on platelet aggregation and secretion and the inhibitory effect of Danshen injection were determined by microplate assay and ELISA. The effects of Danshen injection on platelet nuclear factor kappa B (NF-
κ
B) signaling pathway were assayed by Western Blot.
Result
2
Compared with the blank group, the platelet induction group exhibited significantly elevated absorbance at
A
570
(
P
<
0.01), while the absorbance at
A
570
in the platelet + Danshen injection group was significantly lower than that in the platelet induction group (
P
<
0.01). The comparison with the Danshen injection group revealed that the cell proliferation inhibitory rate in the platelet + Danshen injection group at the same dose was more significant (
P
<
0.01). The number of colonies in the platelet induction group was obviously increased in contrast to that in the blank group(
P
<
0.05), while the number of colonies in the platelet + Danshen injection group was significantly lower than that in the platelet induction group(
P
<
0.05,
P
<
0.01). As demonstrated by comparison with the blank group, TGF-
β
1
content in the supernatant of the platelet induction group rose remarkably(
P
<
0.01), whereas that in the platelet + Danshen injection group declined(
P
<
0.01). Compared with the Danshen injection (24 g·L
-1
) group, the platelet + Danshen injection group displayed more obvious inhibition(
P
<
0.01). Compared with the blank group, Danshen injection significantly reduced the TGF-
β
1
content in platelet supernatant(
P
<
0.05,
P
<
0.01). There was no significant change in the content of TGF-
β
1
in SKOV3 supernatant treated with Danshen injection. The platelet aggregation, thromboxane A
2
(TXB
2
), and serotonin (5-HT) secretion in the SKOV3 cell supernatant induction group were significantly increased as compared with those in the blank group (
P
<
0.01), while such indexes in the cell supernatant induction + Danshen injection group were obviously decreased (
P
<
0.01). Compared with the Danshen injection (24 g·L
-1
) group, the cell supernatant induction + Danshen injection group displayed more obvious inhibition at the same dose(
P
<
0.01). Compared with the blank group, the platelet induction group exhibited obviously up-regulated phosphorylated TGF-
β
-activated kinase-1 (TAK-1) and NF-
κ
B, but down-regulated phosphorylated inhibitory protein of NF-
κ
B (I
κ
B)(
P
<
0.01), which however were significantly reversed in the platelet + Danshen injection group
(
P
<
0.01).
Conclusion
2
Danshen injection affect the proliferation of SKOV3 cells by inhibiting their interaction with platelets, which may be related to the inhibited secretion of TGF-
β
