β
(IL-1
β
),IL-6,IL-10和肿瘤坏死因子-
α
(TNF-
α
)释放;采用实时荧光定量聚合酶链式反应法(Real-time PCR)检测炎症相关因子诱导型一氧化氮合酶(iNOS),前列腺素内过氧化物合酶2(PTGS2)/环氧合酶-2(COX-2)的表达及蛋白免疫印迹法(Western blot)检测磷脂酰肌醇3-激酶(PI3K)/蛋白激酶B(Akt)途径关键蛋白的活化。
结果
2
与空白组比较,LPS(0.5 mg·L
-1
)刺激24 h后能显著促进RAW264.7细胞增殖(
P
<
0.01),与模型组比较,JGL对细胞增殖无显著显著影响;与空白组比较,LPS(0.5 mg·L
-1
)能显著增加NO,IL-1
β
,IL-6,IL-10和TNF-
α
的释放(
P
<
0.01),与模型组比较,JGL(20~300 mg·L
-1
)给药24 h后能剂量依赖性显著抑制NO的释放(
P
<
0.01);与模型组比较,JGL各剂量组IL-1
β
,IL-6,IL-10均明显降低(
P
<
0.05,
P
<
0.01),但对TNF-
α
的释放未见明显的抑制作用;与空白组比较,LPS(0.5 mg·L
-1
)能显著诱导iNOS,PTGS2/COX-2基因表达(
P
<
0.05,
P
<
0.01),与模型组比较,JGL各剂量组能下调iNOS,PTGS2/COX-2 mRNA的表达(
P
<
0.05,
P
<
0.01);与空白组比较,LPS(0.5 mg·L
-1
)组PI3K/Akt通路显著活化(
P
<
0.01),JGL(10,20,40,80 mg·L
-1
)显著降低PI3K p110和p-PI3K p85蛋白及Akt磷酸化水平(
P
<
0.01),抑制PI3K/Akt通路活化。
结论
2
金骨莲提取物能明显抑制LPS诱导的RAW264.7细胞炎症反应,减少炎症因子的释放,其抗炎作用与抑制PI3K/Akt途径有关。
Objective
2
To explore the inhibitory effect and mechanism of Jingulian extract (JGL) on inflammation.
Method
2
The following groups were set up in this study: a control group (10% fetal bovine serum), a lipopolysaccharide (LPS) model group (0.5 mg·L
-1
), and JGL groups (10, 20, 40, 60, 80, 120, 160, 200, 250, 300 mg·L
-1
+ 0.5 mg·L
-1
LPS). The RAW264.7 cells were cultured for 24 hours. Cell proliferation was detected by cell counting kit-8 (CCK-8) assay. Nitric oxide (NO) release was detected by Griess assay. The release of cytokines interleukin (IL)-1
β
, IL-6, IL-10, and tumor necrosis factor (TNF)-
α
was determined by enzyme linked immunosorbent assay (ELISA). The expression of inducible nitric oxide synthase (iNOS) and intraprostaglandin peroxidase synthase 2 (PTGS2)/cyclooxygenase-2 (COX-2) was measured by real-time fluorescence-based quantitative polymerase chain reaction (Real-time PCR) and the activation of key proteins in the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway by Western blot.
Result
2
Compared with the control group, LPS (0.5 mg·L
-1
)could promote the proliferation of RAW264.7 cells after stimulation for 24 hours (
P
<
0.01). Compared with the model group, JGL had no significant effect on cell proliferation. Compared with the control group, LPS (0.5 mg·L
-1
)increased the release of NO, IL-1
β
, IL-6, IL-10, and TNF-
α
(
P
<
0.01). Compared with the model group, JGL (20-300 mg·L
-1
)inhibited the release of NO in a dose-dependent manner after stimulation for 24 hours (
P
<
0.05) and reduced IL-1
β
, IL-6, and IL-10 (
P
<
0.05,
P
<
0.01), but no obvious inhibition on the release of TNF-
α
was observed. LPS (0.5 mg·L
-1
) could induce the expression of iNOS and PTGS2/COX-2 genes as compared with the control group (
P
<
0.05,
P
<
0.01). JGL could down-regulate the mRNA expression of iNOS and PTGS2/COX-2 genes as compared with the model group (
P
<
0.05,
P
<
0.01). LPS (0.5 mg·L
-1
) could activate the PI3K/Akt pathway (
P
<
0.01) as compared with the control group, while JGL (10, 20, 40, and 80 mg·L
-1
) decreased the expression of PI3K-p110, p-p85, and p-Akt (
P
<
0.01), and inhibited the activation of PI3K/Akt pathway.
Conclusion
2
JGL extract could significantly inhibit the inflammatory response and activation of the PI3K/Akt pathway induced by LPS in RAW264.7 cells. The anti-inflammatory effect was related to the inhibition of the PI3K/Akt pathway.
