目的:观察艾灸对癌性疲劳(CRF)小鼠及磷脂酰肌醇3激酶-蛋白激酶B(PI3K-AKT)信号通路的影响.方法:将BALB/C小鼠随机分为空白组10只、模型组15只、艾灸组15只、红外组15只.空白组不进行任何处理,模型组选择4T1乳腺癌细胞系皮下移植联合顺铂构建CRF动物模型,艾灸组及红外组分别予艾灸、红外照射CRF小鼠关元穴4周.干预治疗后检测小鼠行为学(疲劳跑台实验、悬尾实验),并运用酶联免疫吸附试验检测血清白细胞介素-6(IL-6)、肿瘤坏死因子α(TNF-α)含量,蛋白质免疫印迹法检测肿瘤组织磷酸化磷脂酰肌醇3激酶(P-PI3K)、蛋白激酶B(AKT)、磷酸化蛋白激酶B(P-AKT)、B淋巴细胞瘤-2基因(Bcl-2)、胱天蛋白酶-3(Caspase-3)蛋白表达,RT-PCR法检测肿瘤组织IL-6 mRNA及PI3K mRNA表达.结果:与空白组比较,模型组小鼠疲劳跑台时间及距离减少,脾脏指数、跑台电击次数及悬尾时间,血清IL-6、TNF-α含量增加;与模型组比较,干预小鼠跑台时间及距离增加,跑台电击次数和悬尾不动时间,瘤重、脾脏指数、IL-6、TNF-α、P-PI3K、P-AKT与IL-6 mRNA、PI3K mRNA减少,艾灸组Bcl-2含量减少,Caspase-3表达增加;与红外组比较,艾灸组小鼠悬尾不动时间、IL-6、TNF-α、P-PI3K、IL-6mRNA表达减少.结论:艾灸可改善CRF,其机制可能是通过炎症介质介导的PI3K-AKT信号通路发挥作用,而红外线是艾灸起效的重要因素.
Effects of Moxibustion on PI3K-AKT Signaling Pathway in Cancer-related Fatigue Mice
Objective:To observe the effects of moxibustion on cancer-related fatigue(CRF)in mice and its impact on the phos-phoinositide 3-kinase(PI3K)-protein kinase B(AKT)signaling pathway.Methods:BALB/C mice were randomly divided into four groups:blank control group(n=10),model group(n=15),moxibustion group(n=15),and infrared group(n=15).The blank control group received no treatment.The model group was induced with a CRF animal model by subcutaneously transplanting 4T1 breast cancer cells and administering cisplatin.The moxibustion and infrared groups received moxibustion and infrared radiation at the Guanyuan(BL 26)for 4 weeks,respectively.After the intervention,the behavior of the mice was assessed through fatigue tread-mill experiment and tail suspension test.Serum levels of interleukin-6(IL-6)and tumor necrosis factor-alpha(TNF-α)were meas-ured using enzyme-linked immunosorbent assay(ELISA).Western blot was used to detect protein expression of phosphorylated PI3K(p-PI3K),AKT,phosphorylated AKT(p-AKT),B-cell lymphoma 2(Bcl-2),and caspase-3 in tumor tissues.Reverse tran-scription-polymerase chain reaction(RT-PCR)was used to detect the mRNA expression of IL-6 and PI3K in tumor tissues.Re-sults:Compared with the blank control group,the model group exhibited a reduction in fatigue treadmill time and distance,an in-crease in spleen index,treadmill shock frequency,and tail suspension time,as well as elevated serum levels of IL-6 and TNF-α.Compared with the model group,the intervention groups showed an increase in treadmill time and distance,a reduction in shock fre-quency and tail immobility time,a decrease in tumor weight,spleen index,IL-6,TNF-α,p-PI3K,p-AKT,IL-6 mRNA,and PI3K mRNA levels.In the moxibustion group,Bcl-2 levels were reduced,while caspase-3 expression was increased.Compared with the infrared group,the moxibustion group had reduced tail immobility time,IL-6,TNF-α,p-PI3K,and IL-6 mRNA expression.Conclu-sion:Moxibustion can alleviate CRF,and its mechanism may involve the PI3K-AKT signaling pathway mediated by inflammatory mediators.Infrared radiation plays a significant role in the effectiveness of moxibustion.
