摘要:

目的:通过体外实验方法从分子水平对蓝莓叶总黄酮的抗炎功效进行评价。方法:建立人永生化表皮细胞HaCaT与蓝莓叶总黄酮的共培养体系,利用反转录实时荧光定量聚合酶链式反应检测在不同培养时间点(0、15、30、60、120 min)白细胞介素-6(interleukin-6,IL-6)、IL-8、干扰素诱导蛋白-10(interferon-inducibleprotein-10,IP-10)等炎症细胞因子相关基因表达情况,观察蓝莓叶总黄酮的添加对这些基因表达的影响,并探讨蓝莓叶总黄酮在分子水平上的抗炎机理。结果:蓝莓叶总黄酮的添加能够提高抗炎因子IL-6、CXCR-2基因的表达量(P<0.05),降低促炎因子IL-8、IP-10基因的表达量(P<0.05),对CXCR-1基因的表达呈复杂型调节。结论:蓝莓叶总黄酮通过对炎症相关因子表达量产生影响,从而减弱促炎症反应,增强抗炎症反应,最终发挥抗炎功效。

Abstract:

Purpose: To evaluate the in vitro anti-inflammatory potential of total flavonoids from blueberry leaves. Methods:
a co-culture system of HaCaT cell and flavonoids were constructed. To examine the effect of flavonoids on the expression of
inflammatory cytokines including interleukin 6 (IL-6), interleukin-8 (IL-8), and interferon induced protein 10 (IP-10), realtime
reverse transcription quantitative PCR (RT-qPCR) was used to detect the expression of the related genes after co-culture
for different periods of time(0, 15, 30, 60, and 120 min). The anti-inflammatory mechanism of flavonoids from blueberry
leaves was analyzed at the molecular level. Results: The total flavonoids from blueberry leaves significantly enhanced
the expression of anti-inflammatory cytokines (IL-6 and CXCR-2) (P < 0.05) and significantly inhibited the expression of
pro-inflammatory cytokines (IL-8, IP-10) (P < 0.05) to achieve the anti-inflammatory activity. Chemotactic factor receptor
CXCR-1 was regulated complicatedly. Conclusions: The total flavonoids from blueberry leaves could decrease inflammation
by regulating the function of several gene loci via several steps.

Key words: total flavonoids from blueberry leaves, inflammatory cytokines, real-time reverse transcription PCR, anti-inflammatory
